Fluid-wetted or submerged surface cleaning apparatus

An apparatus for cleaning a fluid-wetted or submerged surface, comprising:

• a) a membrane element, comprising:
• i) a generally planar to slightly concave lower surface configured as a means for generating and controlling a cleaning force associated with said generally planar to slightly concave lower surface while said membrane element is in motion;
• ii) an upper surface;
• iii) means for generating and controlling an additional cleaning force which causes said generally planar to slightly concave lower surface and the selected surface to be pressed more closely together while said membrane element is in motion and for structural support associated with said upper surface;
• and
• iv) a perimeter scraping edge surrounding said membrane element and
• b) an elongated handle hinged to said membrane element upper surface.

An apparatus for cleaning a fluid-wetted or submerged surface, comprising:

• a) a membrane element, comprising:
• i) a textured lower surface configured as a means for generating and controlling cleaning force associated with said textured lower surface while said membrane element is in motion;
• ii) an upper surface;
• iii) means for generating and controlling additional cleaning force which causes said textured lower surface and the selected surface to be pressed more closely together while said membrane element is in motion and for structural support associated with said upper surface, wherein said means for generating and controlling additional cleaning force and for structural support comprises a plurality of concentric rings, wherein said plurality of concentric rings increase in height towards a center of said membrane element;
• and
• iv) a perimeter scraping edge surrounding said membrane element and
• b) an elongated handle hinged to said membrane element upper surface, wherein said handle acts as a floatation and motion inducing means for the apparatus.
