  • Patent number: 6101671
    Abstract: The present invention relates to a suction cleaning device which provides liquid dispensing, scrubbing, squeegeeing, and suction drying in a single, compact, self contained device. The suction cleaning device includes a cleaning device housing, a handle connected to the housing, an absorbent cleaning member mounted on the housing and movable between an extended and a retracted position, and a pair of squeegee blades. The squeegee blades are mounted in a squeegee tray, and at least one of the squeegee blades is movable between an extended and a retracted position in response to changes in the relative angle between the housing and the surface being cleaned. The movable squeegee blade is spring-biased into the extended position by one or more springs such as leaf springs. The device includes a suction system which draws the water from the floor surface which has been cleaned into a tank mounted on the housing which collects the liquid from the floor surface.
