Abstract: 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 handle configured to facilitate manual movement of the cleaner over the pool surface.

Abstract: An electric-powered submersible pool cleaner includes a base, discharge conduit, and outwardly extending flange. The base includes an inlet port, and the discharge conduit extends upwardly from the base and circumscribes the inlet port and a portion of an electric-powered impeller to direct the flow of water and debris drawn through the inlet. The outwardly extending flange extends from an upper portion of the discharge conduit and secures a filter to filter debris and pass clean water back into the pool. The impeller includes one or more blades having leading and trailing edges and is set at a height such that the leading edges of the blades are positioned to extend into the discharge conduit below a lower portion of the outwardly extending flange and the trailing edges of the blades extend above the lower portion of the outwardly extending flange. A handle provides maneuverability of the cleaner.

Abstract: A hand-held submersible aquarium power cleaner for cleaning debris from an aquarium, includes an elongated housing having an intake compartment and a filtering compartment therein. A nozzle is positioned at a front end of the housing and is in fluid communication with the intake compartment, wherein a selectively openable channel is provided between the intake compartment and the filter compartment. A filter is disposed in fluid communication with the filter compartment. A water pump assembly has an impeller rotatably connected to an electric motor, wherein the impeller is in fluid communication with the intake compartment. A power switch controls power to the electric motor so that rotation of the impeller draws aquarium water and debris through the nozzle and into the filtering compartment, where the debris is captured and retained by the filter and cleansed water is discharged into the aquarium.

Abstract: A resilient black flexible polymer mat is submerged on the bottom of a small pool or pond to promote the passive solar heating of the water. The upper surface is non-reflective, textured and provided with projecting elements to increase the surface area for enhancing the amount of solar radiation absorbed to heat the mat; the bottom surface has a plurality of spaced-apart projecting frictional supporting members to assist in retaining the mat in position on the bottom of the pool or pond; spaced-apart passages extending between the upper and bottom surfaces permit the movement of water.

Abstract: An adjustable nozzle attachment for a pool cleaner includes a planar member having an upper surface and a lower surface with an orifice formed through the planar member adapted for coupling to a vacuum suction source. A plurality of attaching means are formed on the lower surface of the planar member, each of which is adapted to interchangeably or selectively receive at least one of a plurality of rollers and a plurality of brushes that extend from the lower surface and support the nozzle attachment during movement over a surface being cleaned. When installed, the plurality of rollers and brushes change the nozzle attachment's flexibility characteristics, thereby permitting a user to adjust the overall flexibility of the nozzle attachment, based upon the type of surface to be cleaned.

Abstract: A hand-held, electrically-powered pool cleaner includes a body and a nozzle for suctioning pool water. The body has a filter, an impeller and motor, rechargeable batteries, and a handle for carrying the body and for maneuvering the nozzle along a surface being cleaned the surface. The impeller draws pool water through the nozzle and the filter to remove debris water. A filter housing disposed between the nozzle and the body accumulates the filtered debris. The body optionally includes a pole attachment member to receive the free end of a pole for maneuvering the cleaner from outside of the pool.
