The 500 series Roomba cleans routinelyÃ¢â‚¬Â¦ so you donÃ¢â‚¬â„¢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 BaseÃ¢â€Â¢ to recharge. Roomba efficiently vacuums the entire floor, under and around furniture and along walls and automatically adjusts from carpets to hard floors. Virtual WallÃ¢â€Â¢ Lighthouses confine and guide Roomba from room to room, then direct it to the Home Base to dock and recharge between cleanings.
