Roomba® 971 gives you clean floors every day, in an entire level of your home. Use the iRobot HOME App to clean or schedule from anywhere, anytime. Roomba® 971 knows exactly where it has been and where it needs to go, recharging as needed until the job is done. Its suction power is up to 5X superior (vs. 600 Series), capturing dirt, dust, all types of hair and larger debris from hard floors and carpets. With patented dirt detect sensors, Roomba® 971 works harder where dirt is hiding.
