Abstract
The present application relates to a method and device for cleaning surfaces. In one embodiment, a cleaning device includes a cleaning tool, a motor, a reservoir, an extractor, and a recovery tank. The reservoir stores fluid and may act as a base of the cleaning device. The extractor suctions used fluid from the surface and may be removably attached to the reservoir such that the extractor may be raised and lowered relative to the surface. The recovery tank stores the used fluid from the extractor and may be located adjacent the reservoir. The reservoir may also be formed to fit at least partially around the motor. The cleaning device may also be designed such that at least a portion of the weight of the fluid in the reservoir and the used fluid in the recovery tank is over the cleaning tool.
