An electric-powered submersible vacuum cleaner for filtering water in a pool includes a base with an inlet port extending therethrough. A plurality of wheels extends from the lower surface of the base to facilitate movement of the cleaner over a surface of the pool. An impeller coaxially aligned with the inlet draws water and debris from the pool surface. An electric-powered drive train is coupled to the cleaner and configured to rotate the impeller. A discharge conduit in fluid communication with the inlet extends substantially normal with respect to the upper surface of the base and circumscribes the impeller to direct the flow of water/debris drawn through the inlet by the impeller. A filter mounted over the discharge conduit filters the debris from the drawn water and passes filtered water into the pool. A rotatable handle is attached to and facilitates manual movement of the cleaner over the pool surface.
