The 500 series Roomba cleans routinely… so you don’t have to. 500 Series robots offers the latest innovations from iRobot with unprecedented efficiency, coverage and cleaning performance. Roomba navigates and cleans rooms systematically, then returns to its Home Base™ to recharge. Roomba efficiently vacuums the entire floor, under and around furniture and along walls and automatically adjusts from carpets to hard floors. Virtual Wall™ Lighthouses confine and guide Roomba from room to room, then direct it to the Home Base to dock and recharge between cleanings.
