Abstract: A debris control system for a swimming pool or spa may receive environmental data for the swimming pool or spa, predict debris conditions in the swimming pool or spa based on the received environmental data, and generate a control response based on the predicted debris conditions. A skimming system for a swimming pool or spa may include an actuated weir door. A method of creating a cleaning effect in a swimming pool or spa includes actuating a weir door.

Abstract: A control system for a swimming pool or spa may detect a water level of the swimming pool or spa. The water level may be detected based on information from an APC, information from an environmental sensor, and/or information from an optical sensor. In various embodiments, the control system may determine or estimate a cause of water displacement based on the received information from the APC, environmental sensors, and/or optical sensors.

Abstract: A pool vision system may include a camera and a controller. A method of controlling equipment of a swimming pool or spa using the pool vision system may include receiving visual data from the camera having a field of view including the equipment and identify the equipment in the visual data and determining an operational state of the equipment based on the visual data. The method incudes comparing the determined operational state of the equipment with an expected operational state of the equipment and generating a control response based on a difference between the determined operational state of the equipment and the expected operational state of the equipment.

Abstract: A pool cover for a swimming pool or spa may provide a changeable or adjustable visual indication. A method of controlling the pool cover may include controlling a visual indicator on the pool cover. A pool cover for a swimming pool or spa may include a surface water sensor for detecting at least one characteristic of water accumulated on the pool cover.

Abstract: A method of operating a swimming pool or spa includes controlling equipment for a swimming pool or spa based on a predicted future state of the swimming pool or spa. A method of controlling equipment for a swimming pool or spa may include receiving a scheduled future use for the swimming pool or spa, predicting a future state of the swimming pool or spa based on the scheduled future use, and controlling the equipment to perform cleaning or other action based on the predicted future state. A method of operating a swimming pool or spa includes receiving an indication of a cleaning trigger event, generating a first alert based on the received indication, generating a cleaning response by equipment for the swimming pool or spa, and generating a second alert based on a state of the swimming pool or spa meeting or exceeding a threshold value.

Abstract: A method for managing pool and spa connections is described. The method may involve maintaining a first set of permitted connections to the controller, the permitted connections including at least one pool or spa device connection and at least one pool or spa equipment connection. The method may further involve receiving a connection update instruction to adjust the first set of the permitted connections. The method may further involve updating the first set of permitted connections to define a second set of permitted connections.

Abstract: Communications capabilities are supplied to components of pool water recirculation systems, even if the components lack electrical power or supply wires. Capabilities may be furnished by wireless RF devices that connect to existing fittings or ports of the components, for example. The devices are configured to obtain desired information relating to the components (or the water within them) and transmit the information remotely for processing or consideration.

Abstract: Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may include tracks for movement, with the tracks having teethed internal surfaces. The APCs additionally may supply shift mechanisms for purposes of changing direction of their movement and incorporate bladed scrubbers and easily-opening bodies.

Abstract: Creating and utilizing electricity and radiation via actions of hoses is detailed. Likewise described is using electricity to heat the hoses and radiation to sanitize fluid such as water of a pool or spa. Electricity may be generated by pulsation of the hoses when employed together with a water-interruption type of automatic pool cleaner, for example. Hoses alternatively or additionally may include chemicals or materials reactive to light or other radiation.

Abstract: Systems and methods for communicating wirelessly with automatic pool cleaners are addressed. Hydraulic cleaners, in particular, may be provided with on-board electricity-generating capabilities, processors, sensors, and transceivers for purposes of communication. Control of the cleaners may be accomplished using “smart” devices capable of downloading software via, for example, the Internet.

Abstract: Automatic pool cleaners and associated hoses are detailed. Hoses may contract and expand in use and include sections of differing compliancies. Such contractions and expansions may be intensified in more compliant portions and attenuated in less compliant portions. Also discussed are positive locking mechanisms for adjacent hose sections.
