ABSTRACT:
A hand tool is constructed for detachable connection to a fluid cleaning machine such as a steam cleaning unit. A hollow head has convexly rounded front and rear edges to promote smooth back and forth sliding motion over fabric. Forward and rearward regions of the head constitute a suction chamber and a spray chamber respectively. A fluid solution line is surrounded and protected by a flexible suction hose that is releasably coupled to a neck of the hand tool. A flow control interconnects the fluid solution line and a spray nozzle in the spray chamber. Baffles positioned across a lower opening of the suction chamber reduce wrinkling and ridging tendencies of the fabric as it is being cleaned.
