| Summary of Significant Accounting Policies | 2. 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 consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. The accompanying unaudited financial data as of June 29, 2013 and for the three and six months ended June 29, 2013 and June 30, 2012 has 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 was derived from audited financial statements, but does 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 December 29, 2012, filed with the SEC on February 15, 2013. In the opinion of management, all adjustments necessary to state fairly its statement of financial position as of June 29, 2013 and results of operations and cash flows for the periods ended June 29, 2013 and June 30, 2012 have been made. The results of operations and cash flows for any interim period are not necessarily indicative of the operating results and cash flows for the full fiscal year or any future periods. Reorganization In fiscal year 2012, the Company initiated a reorganization that resulted in, among other things, the centralization of all of the Company's engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, the Company reviewed the financial statement classification of its costs and expenses. As a result of this review, the Company decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of the Company's financial performance. As part of this review, the Company also evaluated the impact of the reorganization on its segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, the Company recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statements of income for the three and six months ended June 30, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity. Revision of Consolidated Balance Sheet as of December 29, 2012 During the three month period ended March 30, 2013, the Company identified a classification error related to its reserves for uncertain tax positions on its December 29, 2012 consolidated balance sheet. The Company had recorded a gross income tax receivable in current assets and a gross uncertain tax positions liability against that receivable in current liabilities as of December 29, 2012. In addition, the Company misclassified certain uncertain tax position liabilities in current and long-term liabilities. The impact of the errors on the December 29, 2012 consolidated balance sheet was a decrease in Other Current Assets of $2.7 million, an increase in Other Assets of $0.2 million, a decrease in Accrued Expenses of $2.9 million, and an increase in Long-term Liabilities of $0.4 million. These adjustments were not considered to be material, individually or in the aggregate, to previously issued financial statements. The Company has revised its December 29, 2012 consolidated balance sheet to correct these errors as reflected herein. This revision had no impact on the consolidated statement of income, the consolidated statement of comprehensive income, or total cash flows from operating activities, investing activities, or financing activities. 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, 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 derives its revenue from product sales, government research and development contracts, 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. Sales to domestic resellers of home robots are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. 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 Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. 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. During the three month period ended June 29, 2013, the Company updated its assessment of customer defective product returns in its home robots business unit. This assessment demonstrated lower actual product returns experience than the estimates included in its historical returns reserve. The Company believes these lower actual returns were the result of its sustained investment in product quality. In the second quarter, the Company accordingly adjusted its accrual rates to reflect these lower return rates, resulting in a $3.5 million benefit to revenue for the three and six month periods ended June 29, 2013. The Company recorded a similar favorable adjustment of $3.3 million in the three month period ended June 30, 2012. Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are 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 currently in effect, 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 June 29, 2013, fiscal years 2007 through 2012 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue. Accounting for Share-Based Payments The Company accounts for share-based payments to employees, including grants of employee stock options and awards in the form of restricted shares and restricted stock units by establishing the fair value of each option grant using the Black-Scholes option pricing model and the fair value of awards based on stock price at the time of grant. The fair value of share-based payments is recorded by the Company as a charge against earnings. The Company recognizes share-based payment expense over the requisite service period of the underlying grants and awards. The Company’s share-based payment awards are accounted for as equity instruments. 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 0.7 million and 1.2 million shares of common stock for the three month periods ended June 29, 2013 and June 30, 2012, respectively, and approximately 0.7 million and 0.6 million shares of common stock for the six month periods ended June 29, 2013 and June 30, 2012, 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 examination by the Internal Revenue Service ("IRS") is closed for fiscal years prior to 2011. During the three month period ended June 29, 2013, the IRS completed its examination of the Company's tax returns for the years 2008, 2009 and 2010. The statute of limitations for examination by state tax authorities is closed for fiscal years prior to 2008. Federal carryforward attributes that were generated prior to fiscal year 2011, and state carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS 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 or changes in tax laws or regulations. The Company's income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. The Company recorded a tax (benefit)/provision of $(0.5) million and $3.3 million for the three month periods ended June 29, 2013 and June 30, 2012, respectively. The $(0.5) million benefit for the three month period ended June 29, 2013 resulted in an effective income tax rate of (6.3)%. The $3.3 million provision for the three month period ended June 30, 2012 resulted in an effective income tax rate of 31.0%. The decrease in the effective income tax rate from 31.0% for the three month period ended June 30, 2012 to (6.3)% for the three month period ended June 29, 2013 was primarily due to the release of $2.7 million of certain income tax reserves due to favorable conclusions of the IRS examination of the Company's income tax returns for the years 2008, 2009 and 2010, and the inclusion of the federal research and development tax credit in the 2013 income tax provision calculation, which was not enacted into law for inclusion in the 2012 income tax provision calculation. The Company recorded a tax provision of $0.02 million and $3.6 million for the six month periods ended June 29, 2013 and June 30, 2012, respectively. The $0.02 million provision for the six month period ended June 29, 2013 resulted in an effective tax rate of 0.1%. The $3.6 million provision for the six month period ended June 30, 2012 resulted in an effective tax rate of 30.8%. The decrease in the effective income tax rate from 30.8% for the six month period ended June 30, 2012 to 0.1% for the six month period ended June 29, 2013 was primarily due to the release of $2.7 million of certain income tax reserves due to favorable conclusions of the IRS examination of the Company's income tax returns for the years 2008, 2009 and 2010, the inclusion of the federal research and development tax credit in the 2013 income tax provision calculation, which was not enacted into law for inclusion in the 2012 income tax provision calculation, and the retroactive reinstatement of federal research and development tax credits in 2013. In January 2013, legislation was enacted that included the extension of the federal research and development tax credits. The legislation retroactively reinstated research and development tax credits for 2012 and extended them through December 31, 2013. As a result, the Company recorded a discrete benefit of $1.8 million related to 2012 during the six month period ended June 29, 2013. The Company anticipates the settlement of state tax audits may be finalized within the next twelve months and could result in a decrease in its unrecognized tax benefits of up to $0.7 million. 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 The Company’s financial assets measured at fair value on a recurring basis at June 29, 2013, were as follows:
The Company’s financial assets measured at fair value on a recurring basis at December 29, 2012, were as follows:
In each table above, the bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period. The realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet. Non-financial Assets The Company's non-financial assets, which include goodwill, intangible assets, and property, plant and equipment are not required to be measured at fair value on a recurring basis. However, the Company evaluates the non-financial assets for impairment if a trigger event occurs, or when an annual impairment test is performed. If the asset is determined to be impaired, the asset is required to be recorded at fair value. During the three month period ended June 29, 2013, the Company decided to refocus its funded research activities. The Company considered this decision to be an indicator of potential impairment for the $0.2 million of goodwill allocated to its Research reporting unit, and the $1.9 million intangible asset, net of accumulated amortization, associated with completed technology acquired as part of its acquisition of Nekton Research LLC completed in September 2008. Using the income approach, the Company determined that the fair value of the Research goodwill after the impairment charge was $0, and the fair value of the completed technology acquired as part of the acquisition of Nekton Research LLC was $124,000. Given that the impairment losses were valued using internal estimates, the Company classified the remaining fair value of long-lived assets as Level 3 in the fair value hierarchy. The Company’s non-financial assets measured at fair value on a non-recurring basis at June 29, 2013, were as follows:
(1) Completed technology acquired as part of the acquisition of Nekton Research, LLC completed in September 2008. 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. The Company first assesses 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. Recent Accounting Pronouncements In July 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This new guidance clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when certain situations exist at the reporting date. This new guidance is effective for annual reporting periods beginning on or after December 15, 2013 and subsequent interim periods. We are currently assessing the impact, if any, on our consolidated financial statements. In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance was effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The impact of these amendments on the Company’s consolidated financial statements was not material. 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 | 4. Stock Option Plans The Company has options outstanding under four stock incentive plans: the 1994 Stock Option Plan (the “1994 Plan”), the 2004 Stock Option and Incentive Plan (the “2004 Plan”), the 2005 Stock Option and Incentive Plan (the "2005 Plan") and the Evolution Robotics, Inc. 2007 Stock Plan (the "2007 Plan" and together with the 1994 Plan, the 2004 Plan and the 2005 Plan, the “Plans”). The 2005 Plan is the only one of the four plans under which new awards may currently be granted. Under the 2005 Plan, which became effective October 10, 2005, 1,583,682 shares were initially reserved for issuance in the form of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards and restricted stock awards. Additionally, the 2005 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning in 2007, by 4.5% of the outstanding number of shares of common stock on the immediately preceding December 31. Stock options 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 2005 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 June 29, 2013, there were 3,909,597 shares available for future grant under the 2005 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 periods from zero to five years, and expire seven or ten years from the date of grant or, if earlier, 60 or 90 days from employee termination. The exercise price of incentive stock options is equal to the closing price on the NASDAQ Global Market on the date of grant. The exercise price of nonstatutory options may be set at a price other than the fair market value of the common stock. On June 7, 2013, the Company granted each of its eight non-employee board members 3,172 restricted stock units. These restricted stock units will vest at the earlier of the first anniversary of the grant or the date of the first annual meeting of the stockholders following the date of grant. |

| Commitments and Contingencies | 6. Commitments and Contingencies Lease Obligations Rental expense under operating leases for the three months ended June 29, 2013 and June 30, 2012 were $1.4 million and $1.1 million, respectively, and for the six months ended June 29, 2013 and June 30, 2012 were $2.4 million and $2.2 million, respectively. Future minimum rental payments under operating leases were as follows as of June 29, 2013:
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 several 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. 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 with respect to the Company’s products. 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 June 29, 2013 and December 29, 2012, respectively. Warranty The Company provides warranties on most products and has established a reserve for warranty based on identified or 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:
Inventory Based upon its business outlook, the Company provides purchase orders and material authorizations to its contract manufacturers for future delivery of finished goods. On the basis of these purchase orders and material authorizations, the Company’s contract manufacturers order components from their respective suppliers. Should the Company’s business outlook not materialize as expected, it may be contractually obligated to purchase from the contract manufacturers inventory they have secured on behalf of the Company, which may be in excess of customer demand. The Company continually evaluates whether any such obligation or exposure exists and records a liability in the period in which such obligations or exposure are identified. |

| Industry Segment, Geographic Information and Significant Customers | 8. Industry Segment, Geographic Information and Significant Customers The Company operates in two reportable segments, the home robots business unit and the defense and security robots business unit. The nature of products and types of customers for the two segments vary significantly. As such, the segments are managed separately. As a result of the reorganization completed at the beginning of fiscal year 2013, the Company determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. While no new reportable segments resulted from the reorganization, certain revenue and expenses previously included in the home robots business unit and the defense and security robots business unit are now combined with other revenue and expenses and presented separately from the two reportable segments. Home Robots The Company’s home robots business unit offers products to consumers through a network of retail businesses throughout the United States, to various countries through international distributors and retailers, and through the Company’s on-line store. The Company’s home robots business unit includes mobile robots used in the maintenance of households. Defense and Security The Company’s defense and security robots business unit offers products through a small U.S. government-focused sales force. Products are also sold to state and local agencies, as well as a limited number of countries, other than the United States, primarily through international distributors but also through a small internationally focused sales team. The Company’s defense and security robots are used by various U.S. and foreign governments, primarily for reconnaissance and bomb disposal missions. Other The Company’s other revenue and cost of revenue result from other smaller business units that do not meet the criteria of a reportable segment, as well as certain operational costs included in cost of revenue. The table below presents segment information about revenue, cost of revenue, gross margin and income before income taxes:
Geographic Information For the three months ended June 29, 2013 and June 30, 2012, sales to non-U.S. customers accounted for 59.3% and 60.2% of total revenue, respectively, and sales to non-U.S. customers for the six months ended June 29, 2013 and June 30, 2012 accounted for 59.6% and 62.6% of total revenue, respectively. Significant Customers For the three months ended June 29, 2013 and June 30, 2012, U.S. federal government orders, contracts and subcontracts accounted for 8.1% and 11.0% of total revenue, respectively, and for the six months ended June 29, 2013 and June 30, 2012, U.S. federal government orders, contracts and subcontracts accounted for 7.7% and 11.3% of total revenue, respectively.

These investments are accounted utilizing the cost method of accounting. The Company regularly monitors the investments to determine if facts and circumstances have changed in a manner that would require a change in accounting methodology. Additionally, the Company periodically evaluates whether or not an investment has been impaired by considering such factors as economic environment, market conditions, operational performance and other specific factors relating to the business underlying the investment. If any such impairment is identified, a reduction in the carrying value of the investment would be recorded at that time. |

| Goodwill, Other Intangible Assets and Other Assets | 9. Goodwill, Other Intangible Assets and Other Assets Goodwill The carrying amount of the Company's goodwill at June 29, 2013 is $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 reporting unit. $7.7 million (net of a subsequent write-down of $0.2 million) resulted from the acquisition of Nekton Research, LLC completed in September 2008 and was assigned to the defense and security reporting unit. In conjunction with the reorganization completed as of the beginning of the fiscal year 2013, the defense and security reporting unit was divided into two reporting units: the defense and security reporting unit and the research reporting unit. As a result, the goodwill of $7.9 million was reassigned utilizing a relative fair value allocation approach. $7.7 million and $0.2 million were reassigned to the defense and security and research reporting units, respectively. During the three month period ended June 29, 2013, the Company decided to refocus its funded research activities. The Company considered this decision to be an impairment indicator, requiring an interim impairment test within the research reporting unit. The Company performed an impairment assessment using the income approach, and determined that goodwill was impaired. The Company recorded an impairment loss of $0.2 million within general and administrative expenses during the three months ended June 29, 2013. Other Intangible Assets Other intangible assets include the value assigned to completed technology, research contracts, and a trade name. The estimated useful lives for all of these intangible assets are two 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 June 29, 2013 and December 29, 2012 consisted of the following:
As part of the Company's decision during the three month period ended June 29, 2013 to refocus its funded research activities, the Company decided to no longer pursue certain research contracts in which completed technology acquired as part of the acquisition of Nekton Research, LLC was utilized. As a result, the Company performed an impairment assessment of the associated intangible asset using the income approach, and recorded an impairment loss of $1.8 million within general and administrative expenses in the three month period ended June 29, 2013. Amortization expense related to acquired intangible assets was $965,000 and $92,500 for the three months ended June 29, 2013 and June 30, 2012, respectively. Amortization expense related to acquired intangible assets was $1.9 million and $185,000 for the six months ended June 29, 2013 and June 30, 2012, respectively. The estimated future amortization expense is expected to be as follows:

| 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 The Company’s financial assets measured at fair value on a recurring basis at June 29, 2013, were as follows:
The Company’s financial assets measured at fair value on a recurring basis at December 29, 2012, were as follows:
In each table above, the bond investments are valued based on observable market values as of the Company’s reporting date and are included in Level 2. The bond investments are recorded at fair value and marked-to-market at the end of each reporting period. The realized and unrealized gains and losses are included in comprehensive income for that period. The fair value of the Company’s bond investments are included in short term investments in its consolidated balance sheet. Non-financial Assets The Company's non-financial assets, which include goodwill, intangible assets, and property, plant and equipment are not required to be measured at fair value on a recurring basis. However, the Company evaluates the non-financial assets for impairment if a trigger event occurs, or when an annual impairment test is performed. If the asset is determined to be impaired, the asset is required to be recorded at fair value. During the three month period ended June 29, 2013, the Company decided to refocus its funded research activities. The Company considered this decision to be an indicator of potential impairment for the $0.2 million of goodwill allocated to its Research reporting unit, and the $1.9 million intangible asset, net of accumulated amortization, associated with completed technology acquired as part of its acquisition of Nekton Research LLC completed in September 2008. Using the income approach, the Company determined that the fair value of the Research goodwill after the impairment charge was $0, and the fair value of the completed technology acquired as part of the acquisition of Nekton Research LLC was $124,000. Given that the impairment losses were valued using internal estimates, the Company classified the remaining fair value of long-lived assets as Level 3 in the fair value hierarchy. The Company’s non-financial assets measured at fair value on a non-recurring basis at June 29, 2013, were as follows:
(1) Completed technology acquired as part of the acquisition of Nekton Research, LLC completed in September 2008. |

| 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 consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. The accompanying unaudited financial data as of June 29, 2013 and for the three and six months ended June 29, 2013 and June 30, 2012 has 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 was derived from audited financial statements, but does 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 December 29, 2012, filed with the SEC on February 15, 2013.

| Reorganization | Reorganization In fiscal year 2012, the Company initiated a reorganization that resulted in, among other things, the centralization of all of the Company's engineering and operations activities. This reorganization was completed at the beginning of fiscal year 2013. In conjunction with this reorganization, the Company reviewed the financial statement classification of its costs and expenses. As a result of this review, the Company decided to classify certain expenses differently than had been classified and presented in prior periods to provide a more clear understanding of the Company's financial performance. As part of this review, the Company also evaluated the impact of the reorganization on its segment reporting and determined that certain modifications were necessary to present the segment information as now viewed by the Company's chief operating decision maker. Although the classification of certain expenses on the income statement has changed in fiscal year 2013 as compared to prior periods, the Company recast the financial results of prior periods in a manner consistent with the fiscal year 2013 presentation for comparability purposes. The reclassified amounts reflected in the consolidated statements of income for the three and six months ended June 30, 2012 included herein conform to the fiscal year 2013 presentation. This reclassification of costs and expenses did not impact previously reported net income or earnings per share as the changes only impacted the categorization of costs within the consolidated statements of income for the periods in question. Consequently, the classification changes did not impact previously presented consolidated balance sheets, statements of cash flow or statements of stockholders' equity. |

| Revision of Consolidated Balance Sheet as of December 29, 2012 | Revision of Consolidated Balance Sheet as of December 29, 2012 During the three month period ended March 30, 2013, the Company identified a classification error related to its reserves for uncertain tax positions on its December 29, 2012 consolidated balance sheet. The Company had recorded a gross income tax receivable in current assets and a gross uncertain tax positions liability against that receivable in current liabilities as of December 29, 2012. In addition, the Company misclassified certain uncertain tax position liabilities in current and long-term liabilities. The impact of the errors on the December 29, 2012 consolidated balance sheet was a decrease in Other Current Assets of $2.7 million, an increase in Other Assets of $0.2 million, a decrease in Accrued Expenses of $2.9 million, and an increase in Long-term Liabilities of $0.4 million. These adjustments were not considered to be material, individually or in the aggregate, to previously issued financial statements. The Company has revised its December 29, 2012 consolidated balance sheet to correct these errors as reflected herein. This revision had no impact on the consolidated statement of income, the consolidated statement of comprehensive income, or total cash flows from operating activities, investing activities, or financing activities. |

| 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, 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 derives its revenue from product sales, government research and development contracts, 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. Sales to domestic resellers of home robots are typically subject to agreements allowing for limited rights of return, rebates and price protection. Accordingly, the Company reduces revenue for its estimates of liabilities for these rights of return at the time the related sale is recorded. The Company makes an estimate of sales returns for products sold by domestic resellers directly based on historical returns experience and other relevant data. 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 Company has aggregated and analyzed historical returns from domestic resellers and end users which form the basis of its estimate of future sales returns by resellers or end users. When a right of return exists, the provision for these estimated returns is recorded as a reduction of revenue at the time that the related revenue is recorded. If actual returns differ significantly from its estimates, such differences could have a material impact on the Company’s results of operations for the period in which the returns become known. The estimates for returns are adjusted periodically based upon historical rates of returns. 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. During the three month period ended June 29, 2013, the Company updated its assessment of customer defective product returns in its home robots business unit. This assessment demonstrated lower actual product returns experience than the estimates included in its historical returns reserve. The Company believes these lower actual returns were the result of its sustained investment in product quality. In the second quarter, the Company accordingly adjusted its accrual rates to reflect these lower return rates, resulting in a $3.5 million benefit to revenue for the three and six month periods ended June 29, 2013. The Company recorded a similar favorable adjustment of $3.3 million in the three month period ended June 30, 2012. Under cost-plus-fixed-fee (“CPFF”) type contracts, the Company recognizes revenue based on costs incurred plus a pro rata portion of the total fixed fee. Costs incurred include labor and material that are 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 currently in effect, 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 June 29, 2013, fiscal years 2007 through 2012 are open for audit by DCAA. In the situation where the Company’s anticipated actual billing rates will be lower than the provisional rates currently in effect, the Company records a cumulative revenue adjustment in the period in which the rate differential is identified. Revenue on firm fixed price (“FFP”) contracts is recognized using the percentage-of-completion method. For government product FFP contracts, revenue is recognized as the product is shipped or in accordance with the contract terms. Costs and estimated gross margins on contracts are recorded as revenue as work is performed based on the percentage that incurred costs compare to estimated total costs utilizing the most recent estimates of costs and funding. Changes in job performance, job conditions, and estimated profitability, including those arising from final contract settlements and government audits, may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Since many contracts extend over a long period of time, revisions in cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to past performance in the current period. When the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the current period. Revenue earned in excess of billings, if any, is recorded as unbilled revenue. Billings in excess of revenue earned, if any, are recorded as deferred revenue. |

| Accounting for Share-Based Payments | Accounting for Share-Based Payments The Company accounts for share-based payments to employees, including grants of employee stock options and awards in the form of restricted shares and restricted stock units by establishing the fair value of each option grant using the Black-Scholes option pricing model and the fair value of awards based on stock price at the time of grant. The fair value of share-based payments is recorded by the Company as a charge against earnings. The Company recognizes share-based payment expense over the requisite service period of the underlying grants and awards. The Company’s share-based payment awards are accounted for as equity instruments. |

| 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 0.7 million and 1.2 million shares of common stock for the three month periods ended June 29, 2013 and June 30, 2012, respectively, and approximately 0.7 million and 0.6 million shares of common stock for the six month periods ended June 29, 2013 and June 30, 2012, 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 examination by the Internal Revenue Service ("IRS") is closed for fiscal years prior to 2011. During the three month period ended June 29, 2013, the IRS completed its examination of the Company's tax returns for the years 2008, 2009 and 2010. The statute of limitations for examination by state tax authorities is closed for fiscal years prior to 2008. Federal carryforward attributes that were generated prior to fiscal year 2011, and state carryforward attributes that were generated prior to fiscal year 2008 may still be adjusted upon examination by the IRS 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 or changes in tax laws or regulations. The Company's income tax provisions and its assessment of the ability to realize its deferred tax assets involve significant judgments and estimates. The Company recorded a tax (benefit)/provision of $(0.5) million and $3.3 million for the three month periods ended June 29, 2013 and June 30, 2012, respectively. The $(0.5) million benefit for the three month period ended June 29, 2013 resulted in an effective income tax rate of (6.3)%. The $3.3 million provision for the three month period ended June 30, 2012 resulted in an effective income tax rate of 31.0%. The decrease in the effective income tax rate from 31.0% for the three month period ended June 30, 2012 to (6.3)% for the three month period ended June 29, 2013 was primarily due to the release of $2.7 million of certain income tax reserves due to favorable conclusions of the IRS examination of the Company's income tax returns for the years 2008, 2009 and 2010, and the inclusion of the federal research and development tax credit in the 2013 income tax provision calculation, which was not enacted into law for inclusion in the 2012 income tax provision calculation. The Company recorded a tax provision of $0.02 million and $3.6 million for the six month periods ended June 29, 2013 and June 30, 2012, respectively. The $0.02 million provision for the six month period ended June 29, 2013 resulted in an effective tax rate of 0.1%. The $3.6 million provision for the six month period ended June 30, 2012 resulted in an effective tax rate of 30.8%. The decrease in the effective income tax rate from 30.8% for the six month period ended June 30, 2012 to 0.1% for the six month period ended June 29, 2013 was primarily due to the release of $2.7 million of certain income tax reserves due to favorable conclusions of the IRS examination of the Company's income tax returns for the years 2008, 2009 and 2010, the inclusion of the federal research and development tax credit in the 2013 income tax provision calculation, which was not enacted into law for inclusion in the 2012 income tax provision calculation, and the retroactive reinstatement of federal research and development tax credits in 2013. In January 2013, legislation was enacted that included the extension of the federal research and development tax credits. The legislation retroactively reinstated research and development tax credits for 2012 and extended them through December 31, 2013. As a result, the Company recorded a discrete benefit of $1.8 million related to 2012 during the six month period ended June 29, 2013. The Company anticipates the settlement of state tax audits may be finalized within the next twelve months and could result in a decrease in its unrecognized tax benefits of up to $0.7 million. |

| 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. The Company first assesses 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. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In July 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This new guidance clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when certain situations exist at the reporting date. This new guidance is effective for annual reporting periods beginning on or after December 15, 2013 and subsequent interim periods. We are currently assessing the impact, if any, on our consolidated financial statements. In February 2013, the FASB issued guidance requiring disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance was effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The impact of these amendments on the Company’s consolidated financial statements was not material. 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. |

This element represents the aggregate carrying amount of all cost-method investments held by the Company. Generally, such investments do not have readily determinable fair values and are not required to be accounted for by the equity method. The carrying amount of such securities equates to cost, adjusted for other-than-temporary impairment. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries, particularly foreign.
