Abstract: A rotary brush having a soap-dispensing feature for cleaning surfaces is disclosed. A rotary brush in accordance with an exemplary embodiment of the present invention includes a brush head assembly operatively coupled to a telescopic handle. The telescopic handle may include an inner chamber configured to receive a cleaning agent that can be periodically delivered to the brush head assembly by pumping action. In certain embodiments, the telescoping handle may include a fluid conduit in fluid communication with the brush head assembly and an external fluid source. In other embodiments, the telescopic handle may be configured to store and deliver a cleaning agent without the use of an external source of fluid. A motor and gearing mechanism may be utilized to drive an inner, rotary brush head surrounded by an outer, stationary brush head.
