A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.

A filter holder for holding an open ended filter having an open proximal end and an open distal end in an operative position on a swimming pool cleaner having a pipe stub for receiving one open end of the filter is shown and described. The filter holder includes a cap for covering one open end of the filter, a coupler configured to cooperate with and engage the pipe stub, and a spanning connector configured to span and connect the cap and the coupler outside the pipe stub of the filter. The coupler may include L-shaped brackets. A constricting collar pins the brackets to the pipe stub. The spanning connector may include compression rods and nuts. The filter holder may include an optional adapter collar separable from the coupler, to adapt diameters of the coupler and the pipe stub. The invention may alternatively be considered to be a mobile swimming pool cleaner having a pleated medium filter rather than a flaccid bag filter.

A pool cleaning tool includes a front housing and a rear housing coupled together, an intake, an outlet, a turbine disposed within the front and rear housings, and a three-way diverter valve proximate the intake. The tool includes an abrasive member, rigidly coupled to the turbine, mounted outside the front and rear housings for rotation with the turbine. The three-way diverter valve has an on position in which water drawn into the intake is communicated into the tool, up to the turbine, and then out the outlet, thereby imparting rotation to the turbine and to the abrasive member.

A pair of cleansing handwear, including a scrubbing surface to scrub a surface of a pool to remove at least one of settlement, dirt, fungus, mildew, mold, and dirt, and at least one fingerless portion, such that at least one of a user's fingers can grasp at least one of tiles, rocks, leaves, and dirt during cleaning of the pool.

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.

An in-water suction cleaner includes a portable housing for disposing at water of a pool or tank, a motorized unit supported in the portable housing for vacuuming a suction cavity of the portable housing to suck the water in the suction cavity out of the portable housing through a fluid outlet of the portable housing so as to create a suction at a fluid inlet of the portable housing, a manual scrubbing arrangement detachably coupled at the fluid inlet of the portable housing for scrubbing pool or tank surfaces and for sucking the water into the suction cavity at the same time, and a filtering element replaceably disposed in the suction cavity for filtering the water from the fluid inlet to the fluid outlet through the suction cavity so as to ensure the water after filtered being discharged back to the pool or tank via the fluid outlet.

A pool cleaning system is provided. The system includes a pool pole. The system also includes an angled attachment device configured to connect to an end of the pool pole. The system additionally includes specialty tools structured to connect to an end of the angled attachment device. The angled attachment device is structured to connect to pool poles and to specialty devices in such a way to provide a plurality of angles to allow cleaning of pool surfaces and pool surface areas in an effective, efficient, and ergonomically friendly fashion for pool cleaning personnel. The pool cleaning system is arranged to change the angles at which the surfaces are being cleaned without having to change out components.

A sonic pool brush including a head assembly with a base having a plurality of electric motors/circuits mounted on an upper surface and a plurality of brush segments positioned in a row along the lower surface of the base. The brush segments connected one each to the electric motors/circuits, for oscillating motion of each individual brush segment when the plurality of electric motors/circuits are energized, each individual brush segment oscillating at a rate in the sonic range. A housing constructed to fit over the motors and engage the base in a waterproof arrangement and a source of electric power attachable to the plurality of electric motors/circuits for energizing the plurality of electric motors/circuits.

There is disclosed a system and method for streaming of volumetric three-dimensional video content. The system includes a separate rendering server and display device such that the rendering server receives pose and motion data from the mobile device and generates completed frames of video for the mobile device. The frames of video are transmitted to the mobile device for display. Predictive algorithms enable the rendering server to predict display device pose from frame-to-frame to thereby reduce overall latency in communications between the rendering server and display device.

A device for cleaning a swimming pool, containing water and comprising a bottom surface thereof, comprises a vacuum head defining a sweeping side, an inlet port, an outlet port and an internal cavity in fluid communication with the inlet and outlet ports. The sweeping side provides for being swept along the bottom surface of the swimming pool and defines an opening leading to the internal cavity. The outlet port provides for being in fluid communication with a vacuum for subjecting the internal cavity to a vacuum force for suctioning water and debris. The inlet port provides for being in fluid communication with a water source for injecting water into the inner cavity during suctioning. The vacuum force via the outlet port in tandem with water injection via the inlet port provides for the vacuum head to suction water and debris via the opening for discharge via the outlet port.
