The Whiz can clean over 5,000 square feet per hour and lasts about 3 hours on a single charge. The battery can be upgraded so the robot can clean for even longer. Users can monitor the robot’s progress via an app and can even overtake control in case of an emergency. The 70-pound floor cleaning robot stands at about 2 feet and can move up to 1.5 miles per hour. Recharging the Whiz’s battery takes 5 hours.
