Abstract: A docking system for an automatic swimming pool cleaner includes a dock and an underwater-facing camera. The underwater-facing camera ay be provided to monitor the automatic swimming pool cleaner underwater. A method of controlling an automatic swimming pool cleaner may include using information obtained from a camera on a dock of a docking system to control the automatic swimming pool cleaner.

Abstract: Debris filters for automatic swimming pool cleaners may be formed of metal, carbon fibers, or composites more rigid than soft nylon bags. In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.

Abstract: An automatic swimming pool cleaner (APC) for swimming pools and spas may skim a waterline of a swimming pool or spa while the APC is on a surface of the swimming pool or spa. The APC may include two inlets—a first inlet may receive or collect water during a surface-cleaning operation of the APC, and a second inlet may receive or collect water during a skimming operation of the APC. Optionally, at least one of the two inlets is adjustable between an open configuration and a closed configuration.

Abstract: Automatic swimming pool cleaners (APCs) may include debris filters accessible from externally of the swimming pools in which the APCs are operating. The APCs may be programmed to climb to waterlines of the pools and present their debris filters above the waterlines for removal by users positioned outside the pools. Sensors may determine whether the filters have been reinstalled within the APCs, thus allowing the APCs to return to cleaning service.

Abstract: Electrical connectors for automatic swimming pool cleaners (APCs) are described. The connectors may be positioned on, at, in, or near bodies of the APCs and configured to be submerged in water of swimming pools. They additionally may be designed to withstand mechanical pulling stresses when their associated electrical cables are pulled by users to remove APCs from the pools. If such a connector is separable, essentially the entirety of the electrical cable may be separated from the APC for purposes of untangling or storing the cable, as examples. The separation additionally may allow for insertion of one or more extension cables as needed or desired.

Abstract: A heat pump for a pool or spa may include a human-machine interface (HMI). The HMI of the heat pump may be movable relative to a housing or body of the heat pump such that regardless of the location and orientation of the installation of the body of the heat pump, the HMI may be positioned so that it is accessible to a user. A heat pump may additionally or alternatively include means for managing condensate created by operation of said heat pump.

Abstract: Concepts relating to automatic swimming pool cleaners (APCs) are detailed. Some concepts may involve communication with APCs either in or out of the water of swimming pools or spas, while other concepts may concern battery charging or management or other operational aspects of cleaner usage in a pool or spa, among others. Many of the concepts may be applicable to avoid need for a robotic APC to be wired to an external control device.

Abstract: An automatic swimming pool cleaner may include a modular battery block attachable to a component of the automatic swimming pool cleaner. The modular battery block may include at least one battery or other source of electrical power that is accessible from externally of the chassis. A venting system or arrangement may be included for venting the modular battery block, such as venting gas produced by at least one battery. Supplying electrical power to an automatic swimming pool cleaner having a chassis and an motor may include (i) attaching a modular battery block to the chassis so as to form an integrated device, and (ii) causing an electrical connection within the integrated device between the motor and at least one battery of the modular battery block.

Abstract: Automatic swimming pool cleaners (APCs) may include separate chassis and bodies. Such constructions may facilitate assembly and disassembly of certain components of the APCs, with or without using tools. APCs with separate chassis and bodies may enable quick and easy access to motor assemblies of the APC, and bodies of the APCs may be readily interchanged on a common chassis.

Abstract: Swimming pool cleaners may operate autonomously within pools and spas. The cleaners need not include any external hoses or cords, and their bodies may be oriented at pool waterlines so as to make their on-board filters readily accessible for removal. The cleaners may dock at docking stations for various purposes, including (but not limited to) for charging any on-board battery and communicating electronically with the docking station or other external equipment.

In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.

Abstract: A swimming pool heating system, including a heat pump and control of the compressor of the heat pump according to a number of non-zero power levels, is detailed. The system includes, for example, three power levels, the first level being close to 40% of the maximum compressor speed, the second level being close to 70% of the maximum compressor speed, and the third level being close to 100% of the maximum compressor speed.

Abstract: Mobile swimming pool cleaners are detailed. Determination of adherence of the cleaners on lateral walls of swimming pools may occur in various ways, and power of pumps of the cleaners may be modified as results of the determinations. User input, further, may be provided indicating whether a cleaner has reached the waterline associated with a lateral wall and whether the cleaner is aspirating air into its inlet.

Abstract: Equipment and methods facilitating suitable orientation of salt-water chlorinators (SWCs) relative to the gravitational field of the Earth are detailed. So orienting an SWC in this manner reduces risk that the volume defined by its gas trap would not be accessible to hydrogen gas generated by the SWC in use. An accelerometer may be employed in connection with the SWC to assist in assessing orientation of the SWC relative to the gravitational field of the Earth.

Abstract: The invention relates to a power lead for a swimming pool cleaning robot. Said power lead comprises a rotary connector and a buoyancy means supporting said rotary connector. An upper part of said buoyancy means is a cap shaped to slide under a swimming pool cover, under the effect of a traction exerted by the swimming pool cleaning robot on the buoyancy means through the power lead.
