Abstract: 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.
