An improved swimming pool brush employing a true wing shape. Consisting of a leading edge continuing to a wing surface that is decreasing in its radius, concave or continually converging toward its leading edge, terminating at the trailing edge. This decreasing radius will empart a greater down force as the liquid passes over the surface, urging the brush against the surface being cleaned. A plurality of slots are incorporated into the surface to allow water to pass through to the rear of the wing surface which acts to cancel out any drag producing low pressure areas. On the return stroke, these slots allow water to pass from back to front decreasing the drag on the brush for effortless retrieval.
