Abstract

A rotor assembly, including a circular spatter shield carrying a cylindrical brush element, is rotatably carried proximate one end of a hollow handle, the other end of which is connectable to a source of pressurized fluid. Delivery tubes extending from the handle direct the liquid against a row of inwardly directed impeller blades carried by the shield to force rotation of the rotor assembly. A fluid impervious flexible skirt coaxially encircles the brush element. A second brush element is stationarily secured to the handle coaxially within the rotor actuated brush element.
