ABSTRACT:
An apparatus for cleaning a selected surface, usually fluid-wetted or submerged, has a membrane element. The membrane element comprises a generally concave lower surface that clings, when in motion, to the selected surface by a first force and a generally convex upper surface. The membrane element has a means associated with the generally convex upper surface which generates a second force which, when in motion, causes the lower surface and the selected surface to be pressed more closely together. particularly embodied as a generally wing shaped cross-sectional profile, wherein the generally wing shaped cross-sectional profile is produced with at least one ring wall comprised of a series of rods projecting up from the generally convex upper surface of the membrane and often a plurality of ring walls formed from projecting rods. An elongated handle, usually a float, is affixed to the membrane element upper surface.
