A Robot That Vacuums

iRobot never intended to call its first consumer product, the self-vacuuming Roomba, a robot. But when every article and review of the product described it as such, iRobot ran with it. With more than six million sold since 2002, iRobot has redefined not only what a vacuum looks like, but what a robot is as well. "If you asked someone today, 'what is a robot?' they wouldn't say Commander Data on Star Trek anymore," says the company's CEO, Colin Angle. "They probably would say, ‘that vacuuming thing.' And that’s good for us."
