A portable debris remover for use under the surface of a volume of water collects or removes debris from an underwater surface by entraining the debris into water and then filtering the water. The portable debris remover includes a body housing with a body mechanism that includes an inlet to receive water with the entrained debris and an outlet configured to discharge water after filtering. A hand operated squeezable bulb is connected to the housing and is operable between an at-rest position and a compressed position. As the bulb is squeezed to the compressed position, water is urged outwardly though the filter and past an open outlet check valve at the outlet. As the bulb is released to return to the at-rest position, some water comes in past the outlet check valve to back flush and clean the screen before the outlet check valve closes. Thereafter, water is urged into the bulb through the now open inlet check valve. The bulb is removable from the body housing so that debris can be removed from the bulb. An extension may be used to position the bulb for more favorable access by the user.

[ What is claimed is:] [1.]1. A portable debris remover for use under the surface of a volume of liquid within a structure having at least one submerged surface upon which debris from said liquid collects, said portable debris remover comprising:a body for positioning under the surface of the volume of liquid, said body having an inlet for positioning relative to said submerged surface and configured to receive liquid with debris from said submerged surface entrained therein, said body having an outlet configured to discharge liquid without said debris to said volume of liquid, said body having an axis and said body being positioned away from said submerged surface at an angle that is less than ninety degrees;a bulb sized for grasping with the hand and for positioning under the surface of the volume of liquid, said bulb having a bulb opening configured to connect to said body to be in communication with said inlet and said outlet, said bulb being formed of a squeezable material operable by the hand of a user between an at-rest position in which said bulb defines a first volume and a compressed position in which said bulb defines a second volume smaller than said first volume;an inlet check valve positioned relative to said inlet and operable between an open position and a closed position, said inlet check valve moving to the open position when liquid flows into said bulb through said bulb opening upon movement of said bulb from said compressed position to said at-rest position, said inlet check valve moving toward the closed position when liquid flows out of said bulb through said bulb opening upon movement of said bulb from said at-rest position to said compressed position;an outlet check valve positioned relative to said outlet and operable between an open position and a closed position, said outlet check valve moving to its open position when liquid flows out of said bulb through said bulb opening upon movement of said bulb from said at-rest position to said compressed position, and said outlet check valve moving toward the closed position after liquid flows into said bulb through said bulb opening upon movement of said bulb from said compressed position to said at-rest position;a screen positioned proximate said outlet to remove debris from said liquid when passing through said outlet; anda nozzle for attachment to said body, said nozzle being formed with an undersurface for contact with and movement over said submerged surface of said structure and said nozzle being formed to entrain debris in liquid urged into said inlet upon movement of said bulb from said compressed position to said at-rest position, said nozzle having a front with ports formed to receive said liquid with said debris entrained there through and a rear spaced from said front and formed to urge debris toward said front upon movement of said nozzle along said submerged surface.
