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.

While iRobot is selling itself off as scrap, let's remember what actually makes a good robovac.

Rodney Brooks, the cofounder of Roomba vacuum creator iRobot, said the idea of humanoid robots as catchall assistants, the future Elon Musk envisions, is “pure fantasy thinking,” in part because robots are coordination-challenged.

For instance, once iRobot perfected the concept for the Roomba, it wasn’t long before the first copies burst onto the scene. iRobot had the brand and the know-how, but that only goes so far against well-motivated copycats.
