Abstract: A self-contained cleaning system particularly suited for use with motor vehicles comprising a storage tank filled with cleaning fluid and containing a pump and a D.C. electric motor, a hose, and an external power cord, and a pistol shaped sprayer head. Depressing a trigger shaped control piece on the sprayer head opens a valve disposed therein and closes an electrical switch that activates the D.C. electric motor which drives the pump, sending cleaning fluid through the hose to the sprayer head. Cleaning fluid is emitted from one of several nozzles on a rotatable nozzle selector on the front of the sprayer head. A locking mechanism, which can hold the control piece in one of several pre-determined positions, along with a magnet in the base of the handle of the sprayer head enables hands free operation of the unit, with the sprayer head secured by the handle to a steel surface such as a car body. The 12 volt D.C.
