A gear change and gear change biasing mechanism for use in an automatic swimming pool cleaner.

An integrated process and system for the cleaning of any body of water in need of periodic cleaning, including but not limited to a swimming pool or spa. A submersible water filtration apparatus comprises a housing unit, an impeller driven by an electric motor powered by batteries, an inlet where fluid, such as water, is drawn inwards into the submersible water filtration apparatus, an outlet for returning filtered water into the body of water, and at least one filter zone.

Pool cleaners are disclosed relating to underwater vacuum cleaning that include a main body, a debris discharge opening, a debris suction opening and a pressure chamber. The pressure chamber may be arranged around an unobstructed cylindrical flow path with the pressure chamber being positioned between the debris discharge opening and the debris suction opening such that water discharged from the pressure chamber directs debris into a debris bag. The cleaners may further be configured to operate by way of a submersible pump, submersible electric motor and a battery.

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 pool cleaner includes a pool cleaner body and at least two wheels mounted to the pool cleaner body so as to be rotatable about a common wheel axis. An access cover selectively closing an access opening defined in the body. A handle closure is mounted to the body so as to be rotatable about the common wheel axis independently of the at least two wheels. The handle closure is rotatable relative to the body so as to be movable between a closed position, in which the handle closure secures the access cover over the access opening, and an open position. An inner cover can selectively cover a turbine and gears of the pool cleaner within the body, and is held in place via engagement with the access over. Wheel well sidewalls can be substantially solid to help further enclose an inner volume of the body.

A submersible water filtration apparatus comprises a housing unit, an impeller driven by an electric motor powered by batteries, an inlet where fluid, such as water, is drawn inwards into the submersible water filtration apparatus, an outlet for returning filtered water into the body of water, and at least one filter zone.

An attachment for a pool vacuum includes a housing and a brushroll at least partially extending from the housing. The brushroll has a plurality of bristles configured to rotate about a first axis. The attachment further comprises a paddle wheel disposed in the housing. The paddle wheel is configured to rotate about a second axis that is parallel to the first axis. The attachment further comprises a torque transmission member coupling the brushroll and the paddle wheel. In response to rotation of the paddle wheel about the second axis, the torque transmission member is configured to rotate the brushroll about the first axis.

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.

An omni-directional wheel for a pool vacuum head includes a first frame and a second substantially identical frame, each frame having a hub rotating around a common axis, lower supports extending radially from the hub, risers extending from the hub along the common axis, and upper supports individually coupled to the risers, the upper supports extending radially from the common axis. Rollers coupled to the first frame and the second frame, are radially spaced from the common axis on each frame. The rollers rotate normal to the common axis to impart omni-directional movement. When the first frame and the second frame are interlocked, the risers on the first frame engage the hub on the second frame, and the lower supports on the first frame engaging the upper supports on the second frame, maintaining the rollers in a staggered arrangement around the wheel.
