<p>A water-operated wash brush which includes a casing that supports a rotary brush and an impellor which drives the rotary brush through a gear train as an incident to direction of wash liquid into the casing from a tangential nozzle. The casing has a clear plastic cover for observing rotary operation of the impellor with the gear train being ascetically disposed on an underside of the impellor. A circular splash plate is interposed between the gear train and the rotary brush for preventing the splash back of wash liquid that might impede operation of the gear train.</p> |
