A device for vacuuming debris from the bottom of a pool of water. The device comprises a housing which forms a frustoconical cavity having a mouth on the lower surface and an exit hole on the top of the frustoconical cavity. A hose is attached on one end to the exit hole and in fluid connection with a source of vacuum.

A water spraying device comprises a water spraying body configured to be fixed to a provided pool above a water level therein. The water spraying body includes a first housing with a support seat disposed therein, and a second housing including a rotating shaft supported by the support seat so the second housing is rotatable relative to the first housing. The water spraying body also includes a spray head in the second housing and configured to discharge water into the provided pool. A base configured to be fixed to the provided pool above a water level in the pool is also provided. In some embodiments, the base includes a side wall with a baffle extending circumferentially therefrom. In such embodiments, the water spraying body includes a casing with a spray head located atop to discharge water into the pool. Also in such embodiments, an abutment portion extends circumferentially around a bottom of the casing and is adapted to abut against the baffle.

A pop-up cleaning head is connectable to a swimming pool pump and is mounted in a swimming pool inner surface. The head has a pressurized extended position and an unpressurized retracted position respectively when pressurized water from the pool pump is connected to, or disconnected from, the cleaning head. The head includes a spring tube having a lower section with a nozzle orifice for directing a high pressure water stream from the swimming pool pump along and adjacent the pool inner surface. The spring tube has an upper section forming a chamber with the lower section and has a vent orifice aligned with the nozzle orifice to permit the high-pressure water stream to emanate from the head through the vent orifice and entrain pool water. The upper section includes passageways communicating with the pool to admit pool water into the chamber to be entrained in the high-pressure water stream emanating from the nozzle. The passageways extend along respective axes that are inclined to the longitudinal axis of the spring tube.

A system used to monitor and control a pool using a visual light communication system is disclosed.

Exemplary embodiments are directed to deck jet systems including an adjustable cover and flexible finishing cap. The deck jet systems include a housing with threads formed on an inner surface of the housing. The deck jet systems include an adjustment ring with threads formed on an outer surface of the adjustment ring complementary to the threads of the housing. The deck jet systems include an adjustable cover, the bottom surface of the adjustable cover being inserted into the proximal end of the housing and supported by a top surface of the adjustment ring. Engagement of the threads of the housing and the adjustment ring and rotation of the adjustment ring relative to the housing can vary an elevation of the adjustment ring relative to the housing which, in turn, varies an elevation of the adjustable cover relative to the housing. Exemplary embodiments are also directed to methods of adjusting a deck jet system.

Detailed are valve assemblies principally for use as part of in-floor cleaning systems for swimming pools. The assemblies may use mechanisms for converting continuous rotation into discontinuous rotation, changing the timing of water distribution to different outlet of the assemblies. One such mechanism includes both an impeller, whose blades are rotated continuously by impingement of pressurized water, and a Geneva drive, whose driven wheel is rotated discontinuously by one or more associated drive wheels.

A pipeline system of an inflatable SPA is provided. The pipeline system includes an air inlet pipeline; a water inlet pipeline, distributed along a circumferential direction of the inflatable SPA; and a plurality of jets for massage, where each of the plurality of jets includes a first water inlet, a first air inlet and an air-liquid mixing outlet, the first air inlet is connected with the air inlet pipeline, the first water inlet is connected with the water inlet pipeline, and air and water can be mixed in each of the plurality of jets and sprayed from the air-liquid mixing outlet. The water with bubbles can be sprayed into pool cavity surrounded by an inner pool wall of the inflatable SPA, which can play a massage effect on users.

A system used to monitor and control a pool using a visual light communication system is disclosed.

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.

A waterjet apparatus can be installed a wall for containing an artificial body of water, such as a pool bottom and/or sidewalls. The waterjet apparatus can be used with an intermittently operated water delivery system to clean pool bottom and/or sidewalls. The waterjet apparatus has a plaster attachment device for securing a plaster mixture to the waterjet apparatus The plaster attachment device can protrude from or be substantially flush with the pool bottom and/or sidewalls.
