| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. The accompanying unaudited financial data as of October 1, 2016, and for the three and nine months ended October 1, 2016 and September 26, 2015 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The year-end balance sheet data were derived from audited financial statements, but do not include all disclosures required by accounting principles generally accepted in the United States. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended January 2, 2016, filed with the SEC on February 19, 2016. In the opinion of management, all adjustments necessary to state fairly the Company's statement of financial position as of October 1, 2016 and results of operations, comprehensive income and cash flows for the periods ended October 1, 2016 and September 26, 2015 have been made. The results of operations, comprehensive income and cash flows for any interim period are not necessarily indicative of the operating results, comprehensive income and cash flows for the full fiscal year or any future periods. Use of Estimates The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, valuation of goodwill and intangible assets, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results and trends, and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates. Fiscal Year-End The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter. Revenue Recognition The Company primarily derives its revenue from product sales. Until the divestiture of the defense and security business unit on April 4, 2016 (see Note 11), the Company also generated minimal revenue from government and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Beginning in the third quarter of 2015, with the introduction of the Company's first connected robot, each sale of a connected robot represents a multi-element arrangement containing the robot, an app and potential future unspecified software upgrades. Revenue is allocated to the deliverables based on their relative selling prices which have been determined using best estimate of selling price (BESP), as the Company has not been able to establish vendor specific objective evidence (VSOE) or obtain relevant third party evidence (TPE). Revenue allocated to the app and unspecified software upgrades is then deferred and recognized on a straight-line basis over the period in which the Company expects to provide the upgrades over the estimated life of the robot. Sales to domestic and Canadian resellers of consumer robots are typically subject to agreements allowing for limited rights of return, rebates and price protection. The Company also provides limited rights of returns for direct-to-consumer sales generated through its on-line stores, one domestic distributor and one international distributor. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return, rebates and price protection at the time the related sale is recorded. These estimates for rights of return are directly based on specific terms and conditions included in the customer agreements, historical returns experience and various other assumptions that the Company believes are reasonable under the circumstances. In the case of new product introductions, the estimates for returns applied to the new products are based upon the estimates for the most similar predecessor products until such time that the Company has enough actual returns experience for the new products, which is typically two holiday return cycles. At that time, the Company incorporates that data into the development of returns estimates for the new products. The Company updates its analysis of returns on a quarterly basis. If actual returns differ significantly from the Company's estimates, or if modifications to individual customer agreements are entered into that impact their rights of returns, such differences could result in an adjustment to previously established reserves and could have a material impact, either favorably or unfavorably, on the Company’s results of operations for the period in which the actual returns become known or the agreement is modified. Except for the one international distributor noted above, the Company's international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. Prior to the Company's divestiture of the defense and security business unit on April 4, 2016 (see Note 11), the Company generated minimal revenue from government contracts. Under cost-plus-fixed-fee (CPFF) type contracts, the Company recognized revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred included labor and material that were directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates submitted by the Company to the Defense Contract Management Agency (DCMA). Annually, the Company submits final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where the Company’s final actual billing rates are greater than the estimated rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (DCAA), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of October 1, 2016, fiscal year 2015 is open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (FFP) contracts was recognized using the percentage-of-completion method. For government product FFP contracts, revenue was recognized as the product was shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts were recorded as revenue as work was performed based on the percentage that incurred costs compared to estimated total costs utilizing the most recent estimates of costs and funding. Revenue earned in excess of billings, if any, was recorded as unbilled revenue. Billings in excess of revenue earned, if any, were recorded as deferred revenue. Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. Stock-based compensation cost for stock options is estimated at the grant date based on each option's fair value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards, time-based restricted stock units and performance-based restricted stock units is measured based on the closing fair market value of the Company's common stock on the date of grant. For performance-based restricted stock units, the compensation costs will be subsequently adjusted for assumptions of achievement during the period in which the assumption of achievement changes, as applicable. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures. Net Income Per Share The following table presents the calculation of both basic and diluted net income per share:
Restricted stock units and stock options representing approximately 0.5 million and 0.7 million shares of common stock for the three-month periods ended October 1, 2016 and September 26, 2015, respectively, and approximately 0.6 million and 0.5 million shares of common stock for the nine-month periods ended October 1, 2016 and September 26, 2015, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive. Income Taxes The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for examinations by the Internal Revenue Service is closed for fiscal years prior to 2013. The statute of limitations for examinations by state tax authorities is closed for fiscal years prior to 2011. Federal carryforward attributes that were generated prior to fiscal year 2013 and state carryforward attributes that were generated prior to fiscal year 2011 may still be adjusted upon examination by the federal or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example, recurring periods of income for tax purposes following historical periods of cumulative losses, generation of tax credits compared to future utilization of credits, or changes in tax laws or regulations. The Company's income tax provision and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. The Company is currently generating state research credits that exceed the amount being utilized. As a result of this trend, a valuation allowance may be needed in the future related to these state tax credits. The Company recorded a tax provision of $8.5 million and $5.8 million for the three months ended October 1, 2016 and September 26, 2015, respectively. The $8.5 million provision for the three months ended October 1, 2016 resulted in an effective income tax rate of 30.2%. The $5.8 million provision for the three months ended September 26, 2015 resulted in an effective income tax rate of 31.1%. The difference between the effective income tax rate of 30.2% for the three months ended October 1, 2016 and 31.1% for the three months ended September 26, 2015 was primarily due to the inclusion of the federal research and development tax credit in the three months ended October 1, 2016 that was not in effect for the three months ended September 26, 2015. The effective income tax rate for the three months ended September 26, 2015 does not include any benefit for the federal research and development tax credit. The federal research and development tax credit was permanently extended as part of the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015. The Company recorded a tax provision of $12.7 million and $11.9 million for the nine months ended October 1, 2016 and September 26, 2015, respectively. The $12.7 million provision for the nine months ended October 1, 2016 resulted in an effective income tax rate of 31.0%. The $11.9 million provision for the nine months ended September 26, 2015 resulted in an effective income tax rate of 32.4%. The difference between the effective income tax rate of 31.0% for the nine months ended October 1, 2016 and 32.4% for the nine months ended September 26, 2015 was primarily due to the inclusion of the federal research and development tax credit in the nine months ended October 1, 2016 that was not in effect for the nine months ended September 26, 2015, partially offset by a discrete income tax expense associated with the sale of the defense and security business. The effective income tax rate for the nine months ended September 26, 2015 does not include any benefit for the federal research and development tax credit. The federal research and development tax credit was permanently extended as part of the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015. Fair Value Measurements The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Financial Assets and Liabilities The Company’s financial assets measured at fair value on a recurring basis at October 1, 2016, were as follows:
The Company’s financial assets and liabilities measured at fair value on a recurring basis at January 2, 2016, were as follows:
Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In accordance with the guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The Company completes the annual impairment evaluation during the fourth quarter each year, or more frequently, if necessary, upon identification of a triggering event. Recent Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-15, "Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 refines how companies classify certain aspects of the cash flow statement in regards to debt prepayment, settlement of debt instruments, contingent consideration payments, proceeds from insurance claims and life insurance policies, distribution from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and for interim periods within fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-15 on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-Based Payment Accounting," which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact of ASU 2016-09 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." ASU 2016-02 requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the standard on its consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, "Income Taxes: Balance Sheet Classification of Deferred Taxes." ASU 2015-17 requires that the presentation of deferred tax assets and liabilities be classified as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. This standard will become effective for fiscal years, and the interim periods within those years, beginning after December 15, 2016, with early adoption allowed. The Company elected to prospectively adopt ASU 2015-17 as of January 2, 2016. The prior reporting period was not retrospectively adjusted. The adoption of this guidance had no impact on the Company's Consolidated Statements of Income and Comprehensive Income. In July 2015, the FASB issued ASU No. 2015-11, "Inventory: Simplifying the Measurement of Inventory." ASU 2015-11 applies only to inventory for which cost is determined by methods other than last-in, first-out and the retail inventory method, which includes inventory that is measured using first-in, first-out or average cost. Inventory within the scope of this standard is required to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new standard will be effective for the Company on January 1, 2017. The Company is currently assessing the potential impact of ASU 2015-11 on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." Under ASU 2015-05, if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. The new standard became effective for the Company on January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation - Amendments to the Consolidation Analysis." ASU 2015-02 reduces the number of consolidation models and changes the way reporting entities evaluate a variable interest entity. It is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company adopted ASU 2015-02 effective January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." ASU 2014-12 requires a reporting entity to treat a performance target that affects vesting and that could be achieved after the requisite service period as a performance condition. It is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company adopted ASU 2014-12 effective January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers," which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods. In July 2015, the FASB voted to defer the effective date of the new accounting guidance related to revenue recognition by one year to December 17, 2017 for annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is in the process of evaluating the impact that the adoption of the new revenue recognition standard issued in May 2014 will have on its consolidated financial statements and footnote disclosures. From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption. |

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
| Stock Option Plans | Stock Option Plans and Stock-Based Compensation The Company has options outstanding under three stock incentive plans: the 2005 Stock Option and Incentive Plan (the "2005 Plan"), the Evolution Robotics, Inc. 2007 Stock Plan (the "2007 Plan") and the 2015 Stock Option and Incentive Plan (the "2015 Plan" and together with the 2005 Plan and the 2007 Plan, the "Plans"). The Company also has restricted stock units outstanding under the 2005 Plan and the 2015 Plan. The 2015 Plan is the only one of the three plans under which new awards may currently be granted. Under the 2015 Plan, which became effective May 20, 2015, 3,100,000 shares were initially reserved for issuance in the form of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards, restricted stock units, unrestricted stock awards, cash-based awards, performance share awards and dividend equivalent rights. Stock awards returned to the Plans, with the exception of those issued under the 2007 Plan, as a result of their expiration, cancellation or termination are automatically made available for issuance under the 2015 Plan. Eligibility for incentive stock options is limited to those individuals whose employment status would qualify them for the tax treatment associated with incentive stock options in accordance with the Internal Revenue Code of 1986, as amended. As of October 1, 2016, there were 1,562,005 shares available for future grant under the 2015 Plan. Options granted under the Plans are subject to terms and conditions as determined by the compensation committee of the board of directors, including vesting periods. Options granted under the Plans are exercisable in full at any time subsequent to vesting, generally vest over four years, and expire five or ten years from the date of grant or, if earlier, 60 or 90 days from employee termination. The exercise price of stock options is equal to the closing price on the NASDAQ Global Market on the date of grant. Other awards granted under the Plans generally vest over periods from one to four years. On September 9, 2016, the Company issued stock-based grants to certain employees, including executive officers. These grants included stock options totaling 45,075 shares of the Company's common stock and 156,860 time-based restricted stock units. Each of the above stock options have a per share exercise price of $39.09, the closing price of the Company's common stock on the NASDAQ Global Market on September 9, 2016. |

| Commitments and Contingencies | Commitments and Contingencies Lease Obligations Rental expense under operating leases for the three months ended October 1, 2016 and September 26, 2015 were $1.6 million and $1.2 million, respectively, and for the nine months ended October 1, 2016 and September 26, 2015 were $4.4 million and $3.6 million, respectively. Future minimum rental payments under operating leases were as follows as of October 1, 2016:
Outstanding Purchase Orders At October 1, 2016, the Company had outstanding purchase orders aggregating approximately $125.5 million. These purchase orders, the majority of which are with contract manufacturers for the purchase of inventory in the normal course of business, are for manufacturing and non-manufacturing related goods and services, and are generally cancelable without penalty. In circumstances where we determine that we have financial exposure associated with any of these commitments, we record a liability in the period in which that exposure is identified. Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses incurred by the indemnified party, generally the Company’s customers, in connection with any patent, copyright, trade secret or other proprietary right infringement claim by any third party. The term of these indemnification agreements is generally perpetual after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of October 1, 2016 and January 2, 2016, respectively. Warranty The Company provides warranties on most products and has established a reserve for warranties based on estimated warranty costs. The reserve is included as part of accrued expenses (Note 5) in the accompanying balance sheets. Activity related to the warranty accrual was as follows:
Sales Taxes The Company collects and remits sales tax in jurisdictions in which it has a physical presence or it believes nexus exists, which therefore obligates the Company to collect and remit sales tax. The Company continually evaluates whether it has established nexus in new jurisdictions with respect to sales tax. The Company has recorded a liability for potential exposure in states where there is uncertainty about the point in time at which the Company established a sufficient business connection to create nexus. The Company continues to analyze possible sales tax exposure, but does not currently believe that any individual claim or aggregate claims that might arise will ultimately have a material effect on its consolidated results of operations, financial position or cash flows. |

| Goodwill, Other Intangible Assets and Other Assets | Goodwill and Other Intangible Assets Goodwill The carrying amount of the Company's goodwill at April 2, 2016 was $48.8 million, of which $41.1 million resulted from the acquisition of Evolution Robotics, Inc. in October 2012 and was assigned to the home robots (now consumer robots) reporting unit. $7.7 million resulted from the acquisition of Nekton Research, LLC completed in September 2008 and was assigned to the defense and security reporting unit. On April 4, 2016, the Company completed the sale of its defense and security business unit and therefore the goodwill balance assigned to the defense and security business unit was written off during the three months ended July 2, 2016. As a result, the Company’s goodwill balance as of October 1, 2016 was $41.1 million. Other Intangible Assets Other intangible assets include the value assigned to completed technology and a trade name. The estimated useful lives for all of these intangible assets are three to ten years. The intangible assets are being amortized on a straight-line basis, which is consistent with the pattern that the economic benefits of the intangible assets are expected to be utilized. Intangible assets at October 1, 2016 and January 2, 2016 consisted of the following:
Amortization expense related to acquired intangible assets was $0.9 million and $0.9 million for the three months ended October 1, 2016 and September 26, 2015, respectively. Amortization expense related to acquired intangible assets was $2.6 million and $2.6 million for the nine months ended October 1, 2016 and September 26, 2015, respectively.

| Disposal Groups, Including Discontinued Operations, Disclosure [Text Block] | Divestiture On April 4, 2016, the Company closed the previously announced sale of the defense and security business unit to iRobot Defense Holdings, Inc., a recently-formed portfolio company of Arlington Capital Partners. The purchase agreement provided for a purchase price of up to $45.0 million, comprising $30.0 million at the closing of the transaction, subject to adjustments for working capital and indebtedness as set forth in the purchase agreement, and up to an additional $15.0 million based on the 2016 revenue of the defense and security business. Based on the final adjustments for working capital and indebtedness, the purchase price was $24.5 million. The Company recognized a gain of $0.4 million on the sale of assets, which is recorded as a component of other income (expense), net, in the nine months ended October 1, 2016. The Company has elected not to recognize the fair value of the earn-out currently, and instead will recognize the earn-out payment if and when it is received. The sale of the defense and security business did not meet the criteria for discontinued operations presentation as it did not represent a strategic shift that had a major effect on the Company's operations and financial results. The Company and iRobot Defense Holdings, Inc. have also entered into a Transition Services Agreement ("TSA"), pursuant to which the Company will continue to perform certain functions on iRobot Defense Holdings Inc.’s behalf during a transition period not to exceed 12 months. The TSA provides for the reimbursement of the Company for direct costs incurred in order to provide such functions and is recorded as a component of other income. |

| Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany accounts and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. The accompanying unaudited financial data as of October 1, 2016, and for the three and nine months ended October 1, 2016 and September 26, 2015 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The year-end balance sheet data were derived from audited financial statements, but do not include all disclosures required by accounting principles generally accepted in the United States. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended January 2, 2016, filed with the SEC on February 19, 2016.

| Use of Estimates | Use of Estimates The preparation of these financial statements in conformity with accounting principles generally accepted in the United States requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates these estimates and judgments, including those related to revenue recognition, sales returns, bad debts, warranty claims, inventory reserves, valuation of investments, valuation of goodwill and intangible assets, assumptions used in valuing stock-based compensation instruments and income taxes. The Company bases these estimates on historical and anticipated results and trends, and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results may differ from the Company’s estimates. |

| Fiscal Year-End | Fiscal Year-End The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition | Revenue Recognition The Company primarily derives its revenue from product sales. Until the divestiture of the defense and security business unit on April 4, 2016 (see Note 11), the Company also generated minimal revenue from government and commercial research and development contracts. The Company sells products directly to customers and indirectly through resellers and distributors. The Company recognizes revenue from sales of robots under the terms of the customer agreement upon transfer of title and risk of loss to the customer, net of estimated returns, provided that collection is determined to be reasonably assured and no significant obligations remain. Beginning in the third quarter of 2015, with the introduction of the Company's first connected robot, each sale of a connected robot represents a multi-element arrangement containing the robot, an app and potential future unspecified software upgrades. Revenue is allocated to the deliverables based on their relative selling prices which have been determined using best estimate of selling price (BESP), as the Company has not been able to establish vendor specific objective evidence (VSOE) or obtain relevant third party evidence (TPE). Revenue allocated to the app and unspecified software upgrades is then deferred and recognized on a straight-line basis over the period in which the Company expects to provide the upgrades over the estimated life of the robot. Sales to domestic and Canadian resellers of consumer robots are typically subject to agreements allowing for limited rights of return, rebates and price protection. The Company also provides limited rights of returns for direct-to-consumer sales generated through its on-line stores, one domestic distributor and one international distributor. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return, rebates and price protection at the time the related sale is recorded. These estimates for rights of return are directly based on specific terms and conditions included in the customer agreements, historical returns experience and various other assumptions that the Company believes are reasonable under the circumstances. In the case of new product introductions, the estimates for returns applied to the new products are based upon the estimates for the most similar predecessor products until such time that the Company has enough actual returns experience for the new products, which is typically two holiday return cycles. At that time, the Company incorporates that data into the development of returns estimates for the new products. The Company updates its analysis of returns on a quarterly basis. If actual returns differ significantly from the Company's estimates, or if modifications to individual customer agreements are entered into that impact their rights of returns, such differences could result in an adjustment to previously established reserves and could have a material impact, either favorably or unfavorably, on the Company’s results of operations for the period in which the actual returns become known or the agreement is modified. Except for the one international distributor noted above, the Company's international distributor agreements do not currently allow for product returns and, as a result, no reserve for returns is established for this group of customers. The estimates and reserve for rebates and price protection are based on specific programs, expected usage and historical experience. Actual results could differ from these estimates. Prior to the Company's divestiture of the defense and security business unit on April 4, 2016 (see Note 11), the Company generated minimal revenue from government contracts. Under cost-plus-fixed-fee (CPFF) type contracts, the Company recognized revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred included labor and material that were directly associated with individual CPFF contracts plus indirect overhead and general and administrative type costs based upon billing rates submitted by the Company to the Defense Contract Management Agency (DCMA). Annually, the Company submits final indirect billing rates to DCMA based upon actual costs incurred throughout the year. In the situation where the Company’s final actual billing rates are greater than the estimated rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is collected from the customer. These final billing rates are subject to audit by the Defense Contract Audit Agency (DCAA), which can occur several years after the final billing rates are submitted and may result in material adjustments to revenue recognized based on estimated final billing rates. As of October 1, 2016, fiscal year 2015 is open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates used, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (FFP) contracts was recognized using the percentage-of-completion method. For government product FFP contracts, revenue was recognized as the product was shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts were recorded as revenue as work was performed based on the percentage that incurred costs compared to estimated total costs utilizing the most recent estimates of costs and funding. Revenue earned in excess of billings, if any, was recorded as unbilled revenue. Billings in excess of revenue earned, if any, were recorded as deferred revenue. |

| Accounting for Share-Based Payments | Stock-Based Compensation The Company accounts for stock-based compensation through recognition of the fair value of the stock-based compensation as a charge against earnings. Stock-based compensation cost for stock options is estimated at the grant date based on each option's fair value as calculated by the Black-Scholes option-pricing model. Stock-based compensation cost for restricted stock awards, time-based restricted stock units and performance-based restricted stock units is measured based on the closing fair market value of the Company's common stock on the date of grant. For performance-based restricted stock units, the compensation costs will be subsequently adjusted for assumptions of achievement during the period in which the assumption of achievement changes, as applicable. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period, net of estimated forfeitures. |

| Net Income Per Share | Net Income Per Share The following table presents the calculation of both basic and diluted net income per share:
Restricted stock units and stock options representing approximately 0.5 million and 0.7 million shares of common stock for the three-month periods ended October 1, 2016 and September 26, 2015, respectively, and approximately 0.6 million and 0.5 million shares of common stock for the nine-month periods ended October 1, 2016 and September 26, 2015, respectively, were excluded from the computation of diluted earnings per share for these periods because their effect would have been antidilutive. |

| Income Taxes | Income Taxes The Company is subject to taxation in the United States and various states and foreign jurisdictions. The statute of limitations for examinations by the Internal Revenue Service is closed for fiscal years prior to 2013. The statute of limitations for examinations by state tax authorities is closed for fiscal years prior to 2011. Federal carryforward attributes that were generated prior to fiscal year 2013 and state carryforward attributes that were generated prior to fiscal year 2011 may still be adjusted upon examination by the federal or state tax authorities if they either have been or will be used in a period for which the statute of limitations is still open. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company monitors the realization of its deferred tax assets based on changes in circumstances, for example, recurring periods of income for tax purposes following historical periods of cumulative losses, generation of tax credits compared to future utilization of credits, or changes in tax laws or regulations. The Company's income tax provision and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. The Company is currently generating state research credits that exceed the amount being utilized. As a result of this trend, a valuation allowance may be needed in the future related to these state tax credits. The Company recorded a tax provision of $8.5 million and $5.8 million for the three months ended October 1, 2016 and September 26, 2015, respectively. The $8.5 million provision for the three months ended October 1, 2016 resulted in an effective income tax rate of 30.2%. The $5.8 million provision for the three months ended September 26, 2015 resulted in an effective income tax rate of 31.1%. The difference between the effective income tax rate of 30.2% for the three months ended October 1, 2016 and 31.1% for the three months ended September 26, 2015 was primarily due to the inclusion of the federal research and development tax credit in the three months ended October 1, 2016 that was not in effect for the three months ended September 26, 2015. The effective income tax rate for the three months ended September 26, 2015 does not include any benefit for the federal research and development tax credit. The federal research and development tax credit was permanently extended as part of the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015. The Company recorded a tax provision of $12.7 million and $11.9 million for the nine months ended October 1, 2016 and September 26, 2015, respectively. The $12.7 million provision for the nine months ended October 1, 2016 resulted in an effective income tax rate of 31.0%. The $11.9 million provision for the nine months ended September 26, 2015 resulted in an effective income tax rate of 32.4%. The difference between the effective income tax rate of 31.0% for the nine months ended October 1, 2016 and 32.4% for the nine months ended September 26, 2015 was primarily due to the inclusion of the federal research and development tax credit in the nine months ended October 1, 2016 that was not in effect for the nine months ended September 26, 2015, partially offset by a discrete income tax expense associated with the sale of the defense and security business. The effective income tax rate for the nine months ended September 26, 2015 does not include any benefit for the federal research and development tax credit. The federal research and development tax credit was permanently extended as part of the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015. |

| Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements The authoritative guidance for fair value establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Financial Assets and Liabilities The Company’s financial assets measured at fair value on a recurring basis at October 1, 2016, were as follows:
The Company’s financial assets and liabilities measured at fair value on a recurring basis at January 2, 2016, were as follows:

| Goodwill | Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company evaluates goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) annually or more frequently if the Company believes indicators of impairment exist. In accordance with the guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a two-step goodwill impairment test is performed. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The Company completes the annual impairment evaluation during the fourth quarter each year, or more frequently, if necessary, upon identification of a triggering event. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-15, "Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 refines how companies classify certain aspects of the cash flow statement in regards to debt prepayment, settlement of debt instruments, contingent consideration payments, proceeds from insurance claims and life insurance policies, distribution from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and for interim periods within fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-15 on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-Based Payment Accounting," which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact of ASU 2016-09 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." ASU 2016-02 requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of the standard on its consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, "Income Taxes: Balance Sheet Classification of Deferred Taxes." ASU 2015-17 requires that the presentation of deferred tax assets and liabilities be classified as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. This standard will become effective for fiscal years, and the interim periods within those years, beginning after December 15, 2016, with early adoption allowed. The Company elected to prospectively adopt ASU 2015-17 as of January 2, 2016. The prior reporting period was not retrospectively adjusted. The adoption of this guidance had no impact on the Company's Consolidated Statements of Income and Comprehensive Income. In July 2015, the FASB issued ASU No. 2015-11, "Inventory: Simplifying the Measurement of Inventory." ASU 2015-11 applies only to inventory for which cost is determined by methods other than last-in, first-out and the retail inventory method, which includes inventory that is measured using first-in, first-out or average cost. Inventory within the scope of this standard is required to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new standard will be effective for the Company on January 1, 2017. The Company is currently assessing the potential impact of ASU 2015-11 on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." Under ASU 2015-05, if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. The new standard became effective for the Company on January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation - Amendments to the Consolidation Analysis." ASU 2015-02 reduces the number of consolidation models and changes the way reporting entities evaluate a variable interest entity. It is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company adopted ASU 2015-02 effective January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." ASU 2014-12 requires a reporting entity to treat a performance target that affects vesting and that could be achieved after the requisite service period as a performance condition. It is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company adopted ASU 2014-12 effective January 3, 2016. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers," which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods. In July 2015, the FASB voted to defer the effective date of the new accounting guidance related to revenue recognition by one year to December 17, 2017 for annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is in the process of evaluating the impact that the adoption of the new revenue recognition standard issued in May 2014 will have on its consolidated financial statements and footnote disclosures. From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption. |

| Income Statement, Balance Sheet and Additional Disclosures by Disposal Groups, Including Discontinued Operations [Line Items] | |
| Disposal Groups, Including Discontinued Operations [Table Text Block] | On April 4, 2016, the Company closed the previously announced sale of the defense and security business unit to iRobot Defense Holdings, Inc., a recently-formed portfolio company of Arlington Capital Partners. The purchase agreement provided for a purchase price of up to $45.0 million, comprising $30.0 million at the closing of the transaction, subject to adjustments for working capital and indebtedness as set forth in the purchase agreement, and up to an additional $15.0 million based on the 2016 revenue of the defense and security business. Based on the final adjustments for working capital and indebtedness, the purchase price was $24.5 million. The Company recognized a gain of $0.4 million on the sale of assets, which is recorded as a component of other income (expense), net, in the nine months ended October 1, 2016. The Company has elected not to recognize the fair value of the earn-out currently, and instead will recognize the earn-out payment if and when it is received. The sale of the defense and security business did not meet the criteria for discontinued operations presentation as it did not represent a strategic shift that had a major effect on the Company's operations and financial results. The Company and iRobot Defense Holdings, Inc. have also entered into a Transition Services Agreement ("TSA"), pursuant to which the Company will continue to perform certain functions on iRobot Defense Holdings Inc.’s behalf during a transition period not to exceed 12 months. The TSA provides for the reimbursement of the Company for direct costs incurred in order to provide such functions and is recorded as a component of other income. |

| Income Statement, Balance Sheet and Additional Disclosures by Disposal Groups, Including Discontinued Operations [Line Items] | |
| Disposal Groups, Including Discontinued Operations [Table Text Block] | On April 4, 2016, the Company closed the previously announced sale of the defense and security business unit to iRobot Defense Holdings, Inc., a recently-formed portfolio company of Arlington Capital Partners. The purchase agreement provided for a purchase price of up to $45.0 million, comprising $30.0 million at the closing of the transaction, subject to adjustments for working capital and indebtedness as set forth in the purchase agreement, and up to an additional $15.0 million based on the 2016 revenue of the defense and security business. Based on the final adjustments for working capital and indebtedness, the purchase price was $24.5 million. The Company recognized a gain of $0.4 million on the sale of assets, which is recorded as a component of other income (expense), net, in the nine months ended October 1, 2016. The Company has elected not to recognize the fair value of the earn-out currently, and instead will recognize the earn-out payment if and when it is received. The sale of the defense and security business did not meet the criteria for discontinued operations presentation as it did not represent a strategic shift that had a major effect on the Company's operations and financial results. The Company and iRobot Defense Holdings, Inc. have also entered into a Transition Services Agreement ("TSA"), pursuant to which the Company will continue to perform certain functions on iRobot Defense Holdings Inc.’s behalf during a transition period not to exceed 12 months. The TSA provides for the reimbursement of the Company for direct costs incurred in order to provide such functions and is recorded as a component of other income. |
