A hand-held, electrically-powered pool cleaner includes a body and a nozzle for suctioning pool water. The body has a filter, an impeller and motor, rechargeable batteries, and a handle for carrying the body and for maneuvering the nozzle along a surface being cleaned the surface. The impeller draws pool water through the nozzle and the filter to remove debris water. A filter housing disposed between the nozzle and the body accumulates the filtered debris. The body optionally includes a pole attachment member to receive the free end of a pole for maneuvering the cleaner from outside of the pool.
