The original Roomba was the first robot vacuum in the US, and the second ever made, following Electrolux’s Trilobite the year prior. A basic bump-and-roll bot with bump and cliff sensors, the Roomba rolled randomly around your home, sucking up dirt, bumping from wall to wall, and generally trying not to fall down stairs.

In last month’s corporate filings, iRobot warned it could file for bankruptcy. The company owes nearly $100 million to Shenzhen Picea Robotics, $2.7 million to BYD, a Chinese electric vehicle company, and $3.4 to the U.S. Customs and Border Protection in unpaid tariffs.
