The PowerDetect™ NeverTouch™ Pro robot vacuum and mop is designed to capture more, reach farther, and need you less (vs. Shark Matrix™ 2-in-1.) After every cleaning run, the robot will return to the NeverTouch™ Pro base to empty debris, refill the water tank, and wash and dry the mopping pad so it’s always ready for its next clean—maintenance-free cleaning for up to a month.
