A pool jet fitting can include an insert housing defining an insert body, a housing channel, and a base disposed within the housing channel. The base can include an outer sidewall that defines an internal chamber. The fitting has a valve disposed within the internal chamber. The valve includes a valve body, a valve channel that extends into the valve body along the first direction, and a valve opening that extends through the valve body and into the valve channel along a second direction that is angularly offset with respect to the first direction. The valve is movable between a first position whereby the valve opening has a first area through which the water flow moves and a second position whereby the valve opening has a second area through which the water flow moves that is greater than the first area.

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 low profile spa jet having a structure allowing for the use of a jet housing for both threaded/nut and grommet installation, wherein the jet protrudes into the spa tub less than 0.5″. The low profile spa jet also can have a jet face/flange that is interchangeable between threaded and grommet jet bodies without changing the relationship to the spa wall, wherein the jet protrudes the same amount in the installed state for both styles of jet body. The low profile spa jet also can have a jet face/flange that is removable and/or interchangeable before and after the jet body and jet internal are installed in the spa.

A spa suction bulkhead or manifold is described. The manifold may be placed behind a removable seat back of the spa or other removable structure. The manifold may have a top portion connected to a main suction line and a main pump line. The top portion may have a cylindrical wall in the center, such that the top portion is divided into a central opening (in fluid communication with the main pump line) and an outer ring portion (in fluid communication with the main suction line). The manifold may also have a cover with a central opening and a plurality of holes formed therein. A spa removable seat back containing jets may fit at its base into the central opening of the cover in fluid connection with the main pump line and allowing the outer ring portion and cover to be exposed for water intake.

A water spraying device is provided, the device including a water spraying body configured to be fixed to a pool above a water level. The water spraying body includes a first housing with a support seat, 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 pool.

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.

Methods and apparatus are disclosed for an improved underwater vacuum cleaning system. Urging elements are provided on a vacuum head to encourage debris, especially large pieces of underwater debris, to matriculate under the head or otherwise toward the vacuum opening, rather than traveling over the head or otherwise NOT toward the vacuum opening. Various embodiments of engagement elements are disclosed between the vacuum head and a vacuum hose to improve the connection therebetween.

A system and method for reinforcing a spa shell includes a structural support layer on an underside of the spa shell. The structural support layer may include an inner layer of rigidizer, a central foam layer, and an outer layer of rigidizer. The structural support layer may extend from a bottom side of the underside of the spa shell, across at least one sidewall of the underside of the spa shell to a lip of the spa shell, the structural support layer forming at least one rib along the sidewall of the underside of the spa shell.
