“iRobot reported another strong quarter, with sustained growth and product momentum throughout the first half of 2006,” said Colin Angle, co-founder and chief executive officer, iRobot. “The increased acceptance of our robots and iRobot’s ability to effectively execute on its plans are key drivers behind the company’s success.”

“We also launched a new version of the iRobot® Scooba® Floor Washing Robot that will sell at $299,” added Angle. “This new price point provides users the option to choose the functionality that works best for their homes.”

iRobot continued to make significant progress in its Government and Industrial robots business, securing a $64.3 million Indefinite Delivery-Indefinite Quantity (IDIQ) contract. The contract, awarded by the Naval Air Warfare Center Training Systems Division, is for iRobot PackBot® EOD robots, spare parts, training and repair services. Under the terms of the IDIQ contract, the military could order up to $64.3 million in robots, spare parts, training and repair services through May 2008.

Business Outlook and Financial Guidance
iRobot improved its financial guidance for 2006 by increasing the lower end of the revenue and pre-tax income range.

“The current trends in our business give us confidence that our revenues and pre-tax earnings results are likely to exceed the low end of our previous guidance,” said Geoff Clear, chief financial officer, iRobot. “Therefore, for full year fiscal 2006, our new revenue guidance is $182 million to $192 million and our pre-tax income guidance is breakeven to a pre-tax profit of two percent of revenues.”
