iRobot, the company behind the Roomba robot vacuum cleaner, is in Chapter 11 bankruptcy, with its Chinese manufacturing partner-cum-creditor poised to pick over the bones. The Roomba has been around for more than two decades, garnering great brand recognition and near-constant hardware and software innovation. It could turn a corner, but iRobot couldn't turn a profit. The company blamed a barrage of reasons for failure, including shipping delays, consumer timidity, and the joy of tariffs, with others pointing the finger at an army of low-cost knock-offs. Perhaps.
