Abstract: An autonomous pool cleaner includes a main body, a filter that is removably coupled to the main body, and an edge engagement assembly. The main body includes a top, a bottom, and one or more peripheral walls that extend between the top and the bottom. The filter is accessible for removal or installation via a particular peripheral wall of the one or more peripheral walls. The edge engagement assembly is configured to extend beyond the particular peripheral wall of the main body and removably secure the autonomous pool cleaner to an edge of a swimming pool so that the filter is accessible and vertically removable when the autonomous pool cleaner is secured to the edge.

Abstract: A method of heating a pool system with a swimming pool and a spa includes operating the pool system in a spa mode or a pool mode. In the spa mode, water is only circulated through the circulation system and the spa, and water of the spa is isolated from water of the pool. In the pool mode, water is only circulated through the circulation system and the pool, and water of the spa is isolated from water of the pool. The method may include automatically switching between the spa mode and the pool mode without mixing water of the pool with water of the spa.

The heater may also include a wiring sensor for determining a wiring configuration for an igniter of the heater. Additionally or alternatively, the heater may include a water inlet sensor, a water outlet sensor, and a vent sensor. The heater for the pool system may be provided with various other sensors or combination of sensors.

Abstract: A method for optimizing a flow of water of a swimming pool or spa includes monitoring a parameter associated with performance of a first piece of equipment of the swimming pool or spa, such as but not limited to a heat pump, and relative to a target for the parameter. The method includes activating a bypass valve such that water bypasses the first piece equipment based on the parameter reaching or exceeding the target. The method includes controlling operation of a second piece of equipment of a circulation system responsive to activation of the bypass valve.

Abstract: A swimming pool cleaner may include at least one light source within its body. The light source may be positioned to project light onto or into (or both onto and into) an on-board filter of the cleaner, facilitating visual examination of the cleanliness of the in situ filter. A transparent region of the body may permit viewing of the on-board filter from outside the body.

Abstract: Techniques and methods for wirelessly communicating with equipment such as, but not necessarily limited to, automatic swimming pool cleaners (APCs) are detailed. An accelerometer or other sensor on-board an APC may recognize such communications. In some cases, varying operation of a motor or other feedback generator of the APC may provide sonic or other feedback in response to the communications.

Abstract: Techniques and methods for wirelessly communicating underwater with equipment such as, but not necessarily limited to, automatic swimming pool cleaners (APCs) are detailed. Such communication avoids any need for conventional wired communication with the APCs. In some cases sounds may be used to communicate, and such sounds may travel through both air and water.

Abstract: Systems and methods for control device detection for pool or spa systems are disclosed. In an example method, a computing system outputs, to a first electrical port, a test signal. The computing system determines an electrical measurement for the first electrical port using the test signal. The computing system identifies a first control device for a first piece of pool or spa equipment based on the electrical measurement. The computing device records first information about the first control device.

Abstract: A bypass mechanism for automatic swimming pool cleaners (APCs) is detailed herein. The bypass mechanism may be a valve or other mechanical device that limits operation of the APC by diverting water away from the APC or otherwise ceasing operation of the APC after a predetermined period of time (e.g., after the desired run-time for the APC has been reached). In this way, the bypass mechanism limits the time the APC operates, even if the pump that otherwise would drive the APC remains energized.

Abstract: Devices, systems, and methods may be used for wirelessly communicating underwater (or through air) with equipment such as, but not necessarily limited to, automatic swimming pool cleaners (APCs). Such communication avoids any need for conventional wired communication with the APCs. At least some of the devices may be hand-held and capable of having at least portions immersed in water in normal use. The devices preferably do not use radio frequency (RF) signal to communication with APCs, instead employing light-based or other signal types.

Abstract: Systems and methods of implementing multiple communication protocols for equipment of a pool or spa system using a bus are described herein. The systems and methods are further configured to coordinate messaging with the equipment using the multiple communication protocols. In an example, a system determines that a first device of equipment of the pool or spa system is associated with a first communication protocol. The system communicates with the first device via the first communication protocol. The system determines that a second device of the equipment of the pool or spa system is associated with a second communication protocol. The system communicates with the second device via the second communication protocol.

Following such detection, the APC may reorient itself so as to re-approach the wall (or other object) in a manner better suited for cleaning the area. The reorientation may occur through, for example, changing speeds of motors on-board the APC, directions of travel of the cleaner, or both.
