The iRobot Roomba® i7 Vacuum Cleaning Robot uses a premium 3-stage cleaning system with dual multi-surface rubber brushes and power-lifting suction to clean different floor surfaces throughout your home. It is ideal for homes with pets, cleaning not only the pet hair you see, but 99% of the allergens you don't. Roomba® i7 learns, maps and adapts to each room, letting you control which rooms are cleaned and when, and recharging as needed until the job is done. The iRobot HOME App connects to your Wi-Fi so you can control when, where, and how your robot cleans, all from your smart phone.
