ABSTRACT:
A portable rotary brush cleaning device for cleaning the inside of a bathtub or other household surfaces, comprising a machine body, a brush handle having two ends, and a motor-driven brush. The brush handle is attached to the machine body at one of its ends and to the brush at its other end. The machine body houses a water tank, a cleaning solution tank, a water pump, and a cleaning solution pump. The pumps supply water and cleaning solution to the brush via hoses that run along the length of the brush handle. A user first wets the brush by activating buttons which control the pumps. The user then activates the motor which causes the brush to rotate upon the brush handle. The user alternates between wetting the brush and rotating the brush on the surface to be cleaned, until the surface has been sufficiently cleaned.
