Abstract
A novel upright, hot water carpet cleaning extractor is disclosed. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be similarly operated in both the forward and reverse direction. The herein taught extractor comprises a base frame including the floor suction nozzle, suction fan, cleaning solution distributor, and a removable combination air/liquid separator and recovery tank. A manipulative push-pull handle is pivotly attached to the base frame having a removable cleaning solution supply tank supported thereon. The herein taught upright extractor is easily stored, self contained, easy to operate and requiring minimal effort by the operator.
