iRobot, the company behind the Roomba robot vacuum, has filed for bankruptcy and will be taken over by its main Chinese supplier, Shenzhen PICEA Robotics Co. The company listed between $100 million and $500 million of assets and liabilities in a filing. iRobot's common stock will be wiped out as a result of the takeover. The company's decline is attributed to its failure to innovate and keep up with competitors.
