As a member of our latest generation of robots, the iRobot Roomba 560 Vacuum Cleaning Robot features the newest innovations for dramatically improved performance, reliability and durability. On-board scheduling allows you to preset up to seven cleaning times per week for Roomba to clean when it's most convenient for you Ã¢?" whether you're at home or on the go. Roomba systematically cleans four rooms on a single charge, gets into hard-to-reach areas like wall edges and beneath furniture, avoids stairs and other drop offs and automatically adjusts from carpets to hard floors and back again. Each Virtual Wall Lighthouse (2 included) confines Roomba to one room until the entire floor is vacuumed before Roomba moves on to the next room. When its battery is running low, or when the cleaning is complete, Roomba automatically returns to its self-charging Home Base to dock and recharge.
