Abstract
The present invention is a surface cleaning liquid extractor for vacuum cleaning a surface. The extractor has an open top recovery tank, a housing which seats upon the recovery tank and a convenient carrying handle which latches the housing and the recovery tank together. The extractor also has a floating splash damper positioned within the recovery tank for floating upon the surface of liquid collected in the tank to minimize splashing of the liquid. The top surface of the floating splash damper includes a domed portion for engaging the suction opening of the extractor and sealing off the suction from the recovery tank when the recovery tank has filled with liquid.
