The present application discloses an automatic water surface skimmer, belonging to the technical field of water surface cleaning. For the existing anti-collision structure, most of impact force is transmitted to a hull through an anti-collision wheel, resulting in that the anti-collision wheel and the hull are damaged, the anti-collision effect is poor, and the service life of the anti-collision wheel and the hull is influenced. Further, garbage collected by adopting the existing solution is easily scatteredly fallen from an opening, and the collection effect is not good. The body of the automatic water surface skimmer is provided with an accommodating cavity running through upper and lower portions, such that a storage member can be placed from the top to the bottom, and it is convenient for a user to disassemble and assemble the storage member. Further, by changing the existing design that the water surface garbage enters from the opening in the front end of the storage member to the design that the garbage enters from the opening in the upper end of the storage member, the collected garbage can be effectively prevented from being scatteredly fallen from the opening in the front end, and the collection effect is good. In addition, the present application includes an anti-collision structure with at least two anti-collision wheels, such that the impact force can be effectively decomposed, the anti-collision effect is good, and the service life of the anti-collision wheels and the body can be effectively prolonged.

Debris filters for automatic swimming pool cleaners may be formed of metal, carbon fibers, or composites more rigid than soft nylon bags. In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.

Skimming devices may use pressurized water from, for example, a return line of a swimming pool or spa. The devices may be adjustable vertically and levelled relative to an upper water surface (waterline) of a pool. They additionally may create “blades” of debris-laden pool water entering their floating heads so as to move debris smoothly and efficiently over wings or foils into associated filters.

A skimmer for removing water from a basin to an outlet conduit includes a buoyant element with a buoyancy sufficient that the skimmer will float generally at a surface of water within the basin; an inlet mounted to an underside of the buoyant element, the inlet pipe defining an inlet located within a perimeter of the buoyant element for receiving water to be transmitted to the outlet conduit; and a flexible membrane arranged circumferentially around the buoyant element. The flexible membrane side wall extends downward from the buoyant element to a position below the inlet, the flexible membrane configured to at least one of, filter water passing through the flexible membrane and redirect water to pass under the flexible membrane, to and through the inlet at a water flow rate. A related kit includes two skirts configured for use in different flow conditions.

A floatation accessory for a pool vacuum is an apparatus that maintains an inverted position for a pool vacuum such that the mouth of the pool vacuum suctions debris along the surface of a pool. The apparatus includes a support platform, a first float, a second float, a support ridge, a handle, an elongated guard, and a suspension system. The support platform upholds the first float and the second float. The first float and the second float are used to float a pool vacuum that is engaged with the apparatus. The support ridge connects the first float and the second float and offsets the elongated guard from the mouth of a pool vacuum. The elongated guard offsets the mouth of a pool vacuum from the side walls of a pool. The suspension system loops a pool vacuum with the support platform, and consequently the first float and the second float.

The present invention provides a water surface cleaning machine, comprising a hull, a cleaning device provided at the bottom of the hull for collecting and storing water surface floating debris, a propulsion device provided at the front end and/or the back end of the hull for propelling the hull to travel on the water surface, a steering device provided at the corner portion between the front end and the side edge of the hull, wherein steering device causes the hull to rotate relative to an obstacle for adjusting traveling direction of the hull when the hull comes into contact with the obstacle during traveling on the water surface, and a power unit provided inside the hull for providing power to the propulsion device and the steering device.

A waste collection device (10) comprising a receptacle (12) having an opening (24) in an upper end and a tubular member (28) mounted for sliding movement within the opening (24). A pump is provided for pumping water outwardly from within the receptacle (12) and a basket is provided within the tubular member (28). The tubular member (28) comprises a cylindrical inner wall (32) and a cylindrical outer wall (33) connected at upper and lower ends thereof to define an annular chamber (36) to provide buoyancy to the tubular member (28).

A powered or non-powered pool skimmer device can include a funnel assembly comprising a funnel having a wide opening and a narrow opening, and a funnel profile extending between the wide opening and the narrow opening, a funnel plate to allow the funnel to freely float or be manually adjusted to position the funnel just beneath the water surface, a filter assembly positioned below the funnel assembly, and a main body with no bottom, so water can flow freely into the swimming pool's main filter system, that fits into an existing skimmer in both height and diameter extending along an axis, which can be locked into the skimmer via a skimmer adapter ring, wherein the funnel assembly, the filter assembly, and the pump assembly are positioned within the main body and arranged along the axis.

A sanitation device for cleaning a body of water in an immersion pool of a mikvah has a hollow member that extends along an axis X. In an operative position suitable for cleaning the device is arranged to extend generally immersed in the water and in a general upright orientation. The device further has an upper opening that in the operative position is arranged to be generally flush with the upper surface of the water and a propeller arranged to rotate about axis X and located at a lower region of the device that is arranged to form a downward flow that urges water to enter the device via the upper opening of the device.

A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.
