Abstract:

A cleaning device including a generating unit, a remote cleaning head having a dispensing chamber through which a heated cleaning solution is applied to a surface to be cleaned, and a closed circuitous system connected to a source of an aqueous liquid, a source of detergent, and the dispensing chamber of the remote head. As the cleaning device is used, liquid and detergent simultaneously enter the circuitous system and are mixed and circulated therein while simultaneously being heated to and maintained at a preselected temperature of about 180. degree. F. to provide a continuing supply of heating cleaning solution at the cleaning head. During use of the device, a suction blower creates a vacuum which extends from a tank within the generating unit through a flexible hose and into a suction chamber in the cleaning head. Thus, spent cleaning solution and entrained soil and debris will be drawn from the surface and into the tank. This tank is automatically evacuated through a drain conduit when the quantity of spent solution therein reaches a predetermined level.
