Abstract
Abstract The invention provides a water-driven brush in the form of a hand-held unit having a water inlet that can be connected to a sink faucet to provide a power source for a rotary brush that can be used for scrubbing plates or pots in the sink. A portion of the water is deflected onto the brush to facilitate the operation and the major water discharge through a main outlet can be used for rinsing the plates or pots.
