A pool cleaner equipped with a rotating brush assembly is disclosed. The brush assembly is removably coupled to the pool cleaner using clamps that are readily accessible, supported by the pool cleaner, and operable by hand. The clamps may be manipulated between a ready configuration, a loaded configuration to receive a brush assembly, and a locked configuration to secure the brush assembly.

A swimming pool cleaner has a housing. The housing has an intake formed on a bottom section thereof. The intake runs along a width of the bottom section of the housing. A first rolling flap is proximate the intake. The first rolling flap is approximately equal in length to a length of the intake. The first rolling flap runs along the width of the bottom section and is hingly coupled to the bottom section of the housing along a front edge of the intake. The first rolling flap follows a contour of a surface of a swimming pool upon which the swimming pool cleaner is traveling upon to control a water flow into the intake.

The present invention provides a structure for assembling and disassembling a dirt suction head to/from a filter bag, comprising a first connection piece and a second connection piece; one end of the second connection piece is detachably connected to a connection pipe of the dirt suction head, and the other end of the second connection piece is provided with a holding cavity; one end of the first connection piece is connected to an opening of an end of a filter bag body, and the other end of the first connection piece is assembled into the holding cavity; or a circumferential side edge of the opening of the filter bag body is tightly pressed and fixed between an outer side wall of the first connection piece and an inner side wall of the holding cavity, which has achieved a quick assembling and disassembling and smooth external aesthetics of a connection position.

An underwater debris suction apparatus includes a power device and a filter device. The power device includes a suction component and a power drive device configured to provide power for the suction component. The underwater debris suction apparatus further includes a collection device, and the upper end of the collection device is provided with an opening. The suction component is at least partially located above the filter device or is entirely located in the space of the filter device. During operation of the suction component, unfiltered pool water enters the filter device through a water inlet channel and flows to the side wall of the filter device, so that the filtered water is discharged from the side wall of the filter device, and the debris that cannot be discharged from the side wall of the filter device falls into the collection device.

An apparatus for removing a layer of sediment which has settled on the bottom of a large water body that includes a structural frame configured to contain a bottom water flow and avoid a re-suspension of sediment outside the vicinity of the structural frame. The structural frame has a control zone configured for containing liquid and suspended particles dispersed during removal of bottom sediment in a suctioning area that is at least about 3 square feet. A sediment removing vacuum unit is operably associated with the structural frame to conduct a suctioned bottom water flow.

An electrically powered pool cleaner may include a housing defining an axial passageway. A rotatable sleeve impeller may be supported by the housing within the axial passageway. The axial passageway may include an unobstructed central portion for passage of fluid and pool debris therethrough into a filter bag removably connected to the housing. A motor may be operatively connected to the sleeve impeller and a power supply operatively connected to the motor. Rotation of the sleeve impeller may accelerate fluid flow through the axial passageway for drawing into the filter bag. The pool cleaner may include a rigid cover enclosing the filter components. The rigid cover may include a handle for handheld operation of the pool cleaner.

Exemplary embodiments are directed to pool cleaners that remove debris from water using a plurality of cyclonic flows, or that include a removable impeller subassembly, a check valve for a debris canister, a particle separator assembly having a handle that locks to the pool cleaner, a modular roller drive gear box, or a roller latch that secures a roller to the pool cleaner. Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.

The invention relates to an underwater cleaner (1), in particular for a swimming pool, comprising a suction nozzle housing (3) having a suction nozzle (2) which communicates with a suction chamber (4), and having a suction mouth (10) which defines a suction plane (9), wherein an outlet channel (5) stems from the suction chamber (4), which outlet channel has a connection (6) for a filter device in the region of its outlet opening (50), and comprising at least one water jet nozzle (7, 12) which opens into the suction chamber (4) in the region of the suction nozzle (2) and via which water can be fed under pressure into the suction chamber (4) such that a negative pressure is established in the suction chamber (4) according to the water jet pump principle, wherein a first water jet nozzle (7) opens into the suction chamber (4) in such a way that a flow center line (7a) of the first water jet nozzle (7) is directed into the outlet channel (5), wherein the first water jet nozzle (7) is formed in one piece with the suction nozzle housing (3) and the suction nozzle housing (3) can be produced together with the first water jet nozzle (7) by injection molding.

To enable easy production, it is provided that the first water jet nozzle (7) can be formed by a slider that can be pulled through the outlet channel (5) from the side (A) of the connection (6) for the filter device, and that the first water jet nozzle (7) widens in the direction of flow of the water jet.

A propeller for attachment to a rotatable output shaft of a submersible motor includes a hub having a first end, and an opposite second end, an outer curved surface, at least two blades extending radially outward from the outer curved surface and a central axial bore for receipt of the output shaft therethrough. The hub includes an arrangement of discharge channels extending between the first and second ends to allow waterflow and debris (e.g., grass, weeds and other stringy items) to pass through the hub and exit the second end without becoming entangled around the base of the motor output shaft.

A liquid-submersible vacuum system includes a housing enclosing a filtration element and a water pump, and a power converter configured to couple to a standard AC power supply. The vacuum system further includes a vacuum-to-waste assembly detachably coupled to the housing for selectively conveying filtered fluid from the vacuum system to a remote location.
