A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

Disclosed is an ultraviolet light disinfection apparatus mounted on a water pipe that is connected to a massage pool. The ultraviolet light disinfection apparatus comprises: a housing mounted on the water pipe and in closed connection with the water pipe; a PCB disposed inside the housing and provided with a UVC-LED light source and a wire, the wire protruding from the housing to connect to the power source; an ultraviolet light-transmitting body disposed on the housing, such that ultraviolet light at UVC wavelength range produced by the UVC-LED light source can enter into water body inside the water pipe through the ultraviolet-transmitting body. The present invention can disinfect the water body inside the water pipe. Also provided are a control box and a massage pool.

A method of adjusting pool or spa equipment parameters in a multi-vendor pool or spa equipment system is provided. The method includes providing a pool or spa equipment system including a plurality of different pool or spa equipment provided by a plurality of different pool or spa equipment suppliers with each of the plurality of different pool or spa equipment having its own adjustable parameters. The method includes connecting the plurality of different pool or spa equipment to a software application via a local network and receiving and displaying current parameter data of the connected plurality of different pool or spa equipment on the software application. The method further includes adjusting, via the software application, the parameters of any one of the connected plurality of different pool or spa equipment.

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.

A swimming pool water sanitizing unit with an ozone generator and a separate ultraviolet (UV) reactor chamber within the same housing unit. The ozone generator may include a water jacket gap between the ozone generator chamber and the outer casing that passes pool water through the gap for cooling. Either of the ozone generator and the UV reactor chamber may include UV intensity sensors to help predict the life of the UV bulb therein. The UV reactor chamber may include rotating water paddle blades to stir up the water within the chamber for enhanced exposure to the UV light. A diverter valve enables diversion of ozone enriched fluid to the pool pump in addition to the UV reactor chamber.

An immersion structure (e.g., hot tub, spa, swim spa, pool, showerhead, whirlpool bathtub, and whirlpool bath) has a water treatment system that includes a nano bubble generator for purifying the water. The water treatment system can further include a gas generator that works in conjunction with the nano bubble generator to create a composition of liquid containing nano bubbles. The nano bubbles circulate in the immersion structure thereby cleaning the plumbing system and water. The water treatment system can be located within a cabinet housing the immersion structure. The system can be controlled (e.g., water treatment, operational parameters, cleaning boost, part replacement, etc.) by a user via a smart app on a client device.

A variable speed pumping system including a variable speed pump, a remote user device, and an auxiliary device is provided. The variable speed pump includes a motor, a drive, a housing including a drive cover, and an onboard controller. The onboard controller includes a plurality of buttons formed in the drive cover, a touchscreen interface positioned on the drive cover, a main circuit board including a non-transitory computer readable medium, the main circuit board being electrically coupled to the touchscreen interface, the motor, and the drive, a wireless communication unit electrically coupled to the main circuit board, and a selectively removable IO expansion module. The onboard controller is configured to control one of a flow rate of the pump or a speed of the motor for a period time and actuate the auxiliary device based on input received on one of the onboard controller or the remote user device.

A pool maintenance system that includes a spectroscopic device that is configured to analyze a fluid of a pool.

A method of sanitising a body of water including the steps of adding sodium chlorite and/or sodium chlorate to the body of water and converting the sodium chlorite and/or sodium chlorate to chlorine dioxide in an electrolysis cell which is in fluid communication with a water circulation system of the body of water.
