Abstract

A system for cleaning an underwater surface includes a cleaning head having a base with a scrubbing pad attached thereto, a hollow handle having leg portions that are connected to openings through the base and an extension tube open toward a rear portion of the cleaning head. A flexible skirt extends perpendicular to the lower surface of the base to surround the sides of the scrubbing pad. A water pump is connected to the extension tube of the handle via a hose to draw water through the base openings to produce a partial vacuum in a space between the base, the skirt and the underwater surface. In one embodiment at least one mechanical filter is disposed downstream of the cleaning head. The system may further include at least one biological and/or chemical filter disposed downstream of the cleaning head.

Claims

1. A system for cleaning an underwater surface, comprising:

a cleaning head comprising;

a base having an upper surface and a lower surface;

a scrubbing pad disposed on the lower surface of the base;

a handle extending from the upper surface of the base, the handle comprising a tubular structure with leg portions penetrating the base to define openings through the base and further having an extension tube open toward a rear portion of the cleaning head;

a skirt extending perpendicular to the lower surface of the base, the skirt comprising a flexible material adapted for creating a partial vacuum seal when the lower surface of the base is held against the underwater surface;

a water pump;

a hose for connecting the extension tube to the water pump so that water is drawn through the openings to produce a partial vacuum in a space between the base, the skirt and the underwater surface; and

a discharge disposed downstream of the pump.

2. The system of claim 1, further comprising at least one mechanical filter disposed downstream of the cleaning head.

3. The system of claim 1, further comprising at least one biological and/or chemical filter disposed downstream of the cleaning head.

4. The system of claim 1, further comprising one or more viewers disposed upstream of the discharge.

5. The system of claim 1, wherein the skirt has a plurality of openings formed therethrough.

6. The system of claim 1, where the scrubbing pad is releasably attached to the base.

7. The system of claim 1, wherein the scrubbing pad comprises an abrasive material selected from the group consisting of scrub brushes, sponges, cloths, carpet and synthetic steel wool substitutes.
