Abstract: An apparatus for cleaning a selected surface, usually fluid-wetted or submerged, has a membrane element. The membrane element comprises a lower surface and an upper surface. The membrane element has a means associated with the upper surface which generates a force which, when in motion, causes the lower surface and the selected surface to be pressed more closely together, particularly embodied as a "wing" cross-sectional profile for added cleaning force and structural support. The lower surface is often textured to create and control fluid motion related inter-surfacial attractive and fluid shearing forces used in the cleaning motion. A perimeter scraping edge surrounds at least a portion of the membrane element. An elongated handle, usually a float, is affixed to the membrane element upper surface. In addition to a slightly concave outer region of the lower surface, the membrane element lower surface may have a concave central region and one or more fluid release apertures piercing the membrane element.
