As a member of our latest generation of home robots, the iRobot Roomba 510 Vacuum Cleaning Robot features the newest innovations for dramatically improved performance, reliability and durability. It systematically cleans three rooms on a single charge, gets into hard-to-reach areas like wall edges and beneath furniture while avoiding stairs and other drop-off. Roomba automatically adjusts from carpets to hard floors and back again. Improved Virtual Wall tells Roomba where to clean by restricting off-limit areas.
