ABSTRACT:
A battery-powered washing unit is described which includes a motor drive unit driven by a DC battery pack with a yoke attached around the motor drive unit. An elongate and extendable handle is connected to the yoke for the user to grasp, and various brushes are connectable to the output shaft of the motor drive unit. Preferably the battery pack is sealed and self-contained and includes an integrated switch member at the top of the battery pack which consists of two powered positions, a low power and high power for various rotary speeds of the brush. Furthermore, the connection between the yoke and the motor drive unit consists of a locking mechanism having at least two locked positions, and a swivel position where the motor drive unit and the brush can swivel relative to the brush handle.
