Abstract: The apparatus for removal of debris from water comprises a body with at least one inlet to allow liquid to flow into the body, a water pump for pulling liquid into and through the body to an outlet, and a grating to catch and collect the debris. Brackets at the side or top of the body permit attachment to a dock or floating platform. The inlet has at least one weir with a shape to create a flow differential at the inlet of the body. The water pump pumps at such a speed to maintain the highest point on the bottom edge of the inlet at a level below the water line outside the body, and to maintain the water level within the body slightly below that of the water outside the body.
