摘要： An apparatus is disclosed for a rotary head cleaner. The apparatus includes a plurality of liquid extraction devices positioned radially on a floor-facing surface of a rotary head, a driveshaft disposed between a rotary motor configured to rotate the rotary head, and a housing disposed between the rotary motor and the rotary head for supporting a wheel, and a handle. The apparatus also includes an evacuation tank having a capacity sensor in communication with an evacuation pump, the capacity sensor configured to detect when a maximum desired capacity of evacuated liquids is reached, a vacuum motor connected with the housing and configured to provide a suction force to the liquid extraction devices to extract liquid from a floor to the evacuation tank, and wherein a weight of the rotary motor, housing, handle, retractable wheel, and vacuum motor is supported by the liquid extraction devices.
