A portable cleaning apparatus includes a handle and a wheel rotatably mounted to the handle having a plurality of scrubbing elements. A nozzle delivers fluid to the scrubbing elements to effect rotation of the wheel. The scrubbing elements can be secured to the wheel to limit pivoting movement of the scrubbing element in a direction of rotation of the wheel while permitting greater pivoting movement of the scrubbing elements in a direction opposite the direction of rotation of the wheel. A dispensing system mounted to the handle is remotely operable to position a dispenser of treatment material in the rotational path of the scrubbing elements to apply treatment material to the scrubbing elements.
