Abstract: A swimming pool cleaning system includes a pool cleaning robot, a floating device, a control unit, and a camera. The floating device is separated from the pool cleaning robot and includes an onboard power source for providing power to the pool cleaning robot. The camera is separated from the pool cleaning robot and is adapted to provide video data and/or image data to the control unit.

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.

Optionally, the determined waterline level may be provided on a user interface of an external device such as but not limited to a control box or a user device. An alert may be provided to a pool owner or other user based on the waterline level relative to a threshold waterline level. Optionally, at least one piece of equipment associated with the swimming pool or spa may be controlled based on the determined waterline level.

The pool or spa control system also includes a modem that facilitates data communications between the sensor system and communication equipment positioned at a different location from the main body of water.

Abstract: Disclosed are filter systems and methods for swimming pools and spas for leaves and other larger debris. The disclosed filtering devices may be provided in-line with a pool cleaning or filtering system such that filtering devices pre-filter the larger debris before the pool cleaning or filtering system filters smaller debris. In some cases, the filtering devices provide an airtight seal that is easy for a user to open or close as desired. In some cases, the disclosed filtering devices include a filter between an inlet and an outlet that are parallel to and offset from a center axis of the filter. In some cases, the filtering devices are configured to generate horizontal cyclonic flow of water.

Each turbine of the one or more turbines may include a non-uniform height, and a maximum height of the plurality of blades is at the center axis.

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: A method of self-assigning an IP address to an item of pool or spa equipment can include randomly selecting, by the item of pool or spa equipment, an IP address from a predetermined IP address range. The method can also include transmitting, by the item of pool or spa equipment, the IP address and a serial number to a target parent node. Additionally, the method can include listening, by the item of pool or spa equipment, for a broadcast topology message from the target parent node. Further, the method can include determining, by the item of pool or spa equipment, that the IP address is valid based on the broadcast topology message and, upon determining that the IP address is valid, completing a startup process by the item of pool or spa equipment.

Abstract: A docking station for a pool cleaner includes at least one inductive element for charging the pool cleaner. A docking station for a pool cleaner may include means for guiding the pool cleaner to the docking station using light-based communication. In certain embodiments, the docking station for a pool cleaner may include means for engaging and/or supporting the pool cleaner at a waterline of a swimming pool or spa. A docking station for a pool cleaner a may enclose a pool cleaner within a receiving area in certain embodiments.

Abstract: A pool cleaner for a swimming pool or spa includes a pump with a flow outlet for directing a flow of water from the pump. The flow outlet includes a plurality of flow guides defining flow paths for the water, and, in some cases, the plurality of flow guides may guide the flow of water along a non-linear path. In certain cases, a height of the plurality of flow guides is less than a height of the flow outlet.

Abstract: A water testing pod for testing water of a swimming pool or spa includes a predefined volume of a predefined testing reagent encapsulated and sealed within a polymer membrane. A water testing system may include one or more of the water testing pods and a dispensing system, which may receive the one or more water testing pods and rupture the membrane for releasing the predetermined dosage of the testing reagent into the water of the swimming pool or spa. A method of testing water of a swimming pool or spa with a water testing system includes releasing a predetermined dosage of a testing reagent into the water of the swimming pool or spa by rupturing a membrane of a water testing pod.
