Some embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, a user interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a power parameter associated with the motor and compares the power parameter to a predetermined threshold value. The controller triggers a safety vacuum release system based on the comparison of the power parameter and the threshold value.

A pool cleaner generator module with magnetic coupling. The generator module can include a housing, a paddle wheel, a magnetic follower, and a generator. The generator can power components of the pool cleaner, such as light emitting diode (LEDs). The housing can be removably coupled to the pool cleaner and can include a flow directing portion positioned in a fluid path of the pool cleaner. The paddle wheel can be located adjacent to the flow directing portion and can rotate in response to fluid flow through the fluid path. The generator can be magnetically coupled to the paddle wheel and can generate power through rotation of the paddle wheel. The LED can be coupled to the generator and can receive the generated power from the generator to illuminate an area adjacent to the pool cleaner.

An automatic pool cleaner comprising a housing and a base. The housing comprises a suction flow pathway, an impeller disposed within the housing and in fluid communication with the suction flow pathway such that water traveling through the suction flow pathway spins the impeller, an off-center cam that extends through the impeller and is configured to rotate as the impeller rotates, and two spring biased valves. Each valve comprises a valve seat, and a spring biased poppet configured to seal against the valve seat, the poppet having a rod with a spring disposed around the rod. The base comprises two feet, each foot having a spring-biased pad extending from each end of the foot, two A-arm assemblies, one for each foot, and a suction port that extends through the base.

Swimming pool cleaning apparatus may include a cleaning unit intended to be immersed in a swimming pool and at least one liquid filter circuit between at least one liquid inlet and at least one liquid outlet via a filter chamber removable from the body of the cleaning unit. The filter chamber may include a cover and a filter basket. The cover may include components for fastening the filter basket and locking the filter chamber to the body of the cleaning unit. The locking component may be releasable and, when released, may cause an extraction handle to be deployed from the filter chamber and urged toward a predetermined position.

The present application discloses an automatic water surface skimmer, belonging to the technical field of water surface cleaning. For the existing anti-collision structure, most of impact force is transmitted to a hull through an anti-collision wheel, resulting in that the anti-collision wheel and the hull are damaged, the anti-collision effect is poor, and the service life of the anti-collision wheel and the hull is influenced. Further, garbage collected by adopting the existing solution is easily scatteredly fallen from an opening, and the collection effect is not good. The body of the automatic water surface skimmer is provided with an accommodating cavity running through upper and lower portions, such that a storage member can be placed from the top to the bottom, and it is convenient for a user to disassemble and assemble the storage member. Further, by changing the existing design that the water surface garbage enters from the opening in the front end of the storage member to the design that the garbage enters from the opening in the upper end of the storage member, the collected garbage can be effectively prevented from being scatteredly fallen from the opening in the front end, and the collection effect is good. In addition, the present application includes an anti-collision structure with at least two anti-collision wheels, such that the impact force can be effectively decomposed, the anti-collision effect is good, and the service life of the anti-collision wheels and the body can be effectively prolonged.

Various aspects of the present disclosure are directed to swimming pool vacuum cleaners. In one example embodiment, the pool vacuum cleaner includes a main body having a housing with an impeller driven by an electric motor, an inlet opening in a bottom region of the housing, and an outlet opening on an outlet side of the housing. The vacuum cleaner further includes a collecting container receptacle that accommodates a collecting container arranged in the region of the outlet opening, a rod receptacle releasably connected to a guide rod arranged in the region of the outlet side, and a guide fork pivotably connected to the housing about a pivot axis. The rod receptacle arranged on the guide fork. The pivot axis is arranged at a distance from a center of mass of the main body, and the center of mass is arranged between the pivot axis and the outlet opening.

A fountain apparatus may include a wall insert that can be threadably attached to a water inlet port in the wall of a pool. The wall insert may split water flow into two streams, one that passes through a jet nozzle ball and into the pool, and the other that flows into a reservoir that supplies water to a stream nozzle tip to form a water fountain. A water insert reservoir cap may be releasably engageable with the wall insert and include two fluid passageways, one corresponding to the flow path to the jet nozzle ball and the other corresponding to the reservoir and the flow path to the stream nozzle tip. A reservoir locking cap may be used to secure the wall insert reservoir cap to the wall insert. A jet nozzle cap may be used to secure the jet nozzle ball to the reservoir locking cap.
