A non-chemical sanitation system for a body of water comprises a floating base, an internal hydro-electric power generator, and one or more sanitizing mechanisms electrically powered by the hydro-electric power generator, where the hydro-electric power generator derives its energy from water pressure produced by a pool pump. In some embodiments, the one or more non-chemical sanitizing mechanisms comprise one or more ultraviolet LED lights. In some embodiments, the one or more non-chemical sanitizing mechanisms comprise one or more ionizers. In some embodiments, the system is connected to a filter pipe and filter of a pool and the hydro-electric power generator is placed within the path of water flowing to the pool filter in order to generate power and power the one or more sanitizing mechanisms.

A suctioning device for suctioning impurities from the bottom of large artificial water bodies is provided. The suctioning device includes a flexible sheet configured to provide a structural frame; a plurality of first brushes depending from the sheet; a plurality of middle brushes; a plurality of lateral brushes; a plurality of suction points; a plurality of wheels configured to provide secondary support when the brushes are worn out; a plurality of collectors configured to gather the suctioned water into external suction lines; a plurality of internal suction lines configured to conduit the suctioned bottom water flow from the plurality of suction points to the plurality of collecting means; and a coupling device connecting the internal suction lines and the collectors, wherein a rate of the bottom water flow entering the suctioning device is the same or higher than a rate of water flow suctioned by an external pumping system.

A pool hose air evacuation module includes a cover having an upstream connector, and a downstream connector. The cover includes a primary inlet port proximate the upstream connector and a secondary discharge port proximate the downstream connector. The module includes a main conduit, a primary conduit in fluid communication with the primary inlet port and the downstream connector, and a primary impeller mounted within the primary conduit that is configured to be driven by a pool water flow through the primary conduit when the valve is in a closed position. The module also includes a secondary conduit in fluid communication with the upstream conduit and the secondary discharge port, and a secondary impeller is mounted within the secondary conduit that is configured to be driven by the primary impeller to remove air from the pool hose.

A discharge vacuum relief valve kit to provide vacuum relief for a SVRS pump in a hydraulic system is provided. The discharge vacuum relief valve kit includes a vacuum vent tube including a first end and a second end, a discharge vacuum relief valve coupled to the first end of the vacuum vent tube, and a vacuum vent screen coupled to the second end of the vacuum vent tube. The discharge vacuum relief valve is coupled to a drain plug opening of the SVRS pump.

Systems and methods for circulating water of swimming pools or spas are detailed. The systems may include both a main filtration pump and a secondary booster pump, with the booster pump containing a variable-speed motor. By adjusting motor speed of the booster pump, pressurized water may be supplied to certain automatic swimming pool cleaners more efficiently, without need for energy-wasting by-pass paths or restrictor plates.

A pool cleaner cover for use with a pool vacuum includes a body portion having a top wall and a continuous side wall extending downwardly from the top wall such that the cover body defines an interior area, the side wall including a lower rim that defines an open bottom allowing access to the interior area. The top wall defines an aperture providing access to the interior area. A mounting portion having a tubular configuration is situated in the interior area and has upper and lower open ends. The upper end extends upwardly through the aperture and is configured to selectively receive a lower end of a pool vacuum hose. The lower end is situated in the interior area and configured to connect to a hose coupling of a pool vacuum.

The present invention provides a structure for assembling and disassembling a dirt suction head to/from a filter bag, comprising a first connection piece and a second connection piece; one end of the second connection piece is detachably connected to a connection pipe of the dirt suction head, and the other end of the second connection piece is provided with a holding cavity; one end of the first connection piece is connected to an opening of an end of a filter bag body, and the other end of the first connection piece is assembled into the holding cavity; or a circumferential side edge of the opening of the filter bag body is tightly pressed and fixed between an outer side wall of the first connection piece and an inner side wall of the holding cavity, which has achieved a quick assembling and disassembling and smooth external aesthetics of a connection position.
