ABSTRACT:
A plastic housing shell has two spaced apart bosses in it and first and second shafts extend in parallelism from the bosses. A turbine rotor has a bore that fits loosely over the first shaft and has a concentric first pinion with the same oversized bore. A gear and an integral pinion are journaled on the second shaft. The gear meshes with the pinion on the turbine rotor and the pinion on the gear meshes with a gear on a base ring of a rotary brush. The gear on the brush ring has a bored cylindrical shaft extending axially from it which slips over the first shaft for the brush to rotate on it while the periphery of the cylindrical shaft fits into the bore of the pinion and rotor so the rotor is journaled on said cylindrical shaft. Springy latch prongs engage a cover through which the brush extends so said cover retains all of the brush assembly parts in assembled condition. No other fasteners are required. A conduit that supplies the water jet for driving the turbine serves as a handle for the brush.
