A cleaning head for cleaning a submerged surface includes a body portion, and a skirt portion extending around a periphery of the body portion, the skirt portion performing a sealing function between the body portion and a submerged surface desired to be cleaned when the cleaning head is disposed on the submerged surface during use. The cleaning head also includes at least one cleaning member for causing material on the submerged surface to separate from the submerged surface when the cleaning head is disposed on the submerged surface during use, and at least one suction aperture in fluid communication with a space defined between the body portion and the submerged surface during use.
