A detection and tracking system and method using a camera unit on a robot, or alternatively a camera mounted inside the pool overlooking the bottom of the pool, for safety monitoring for use in and around water-related environments. The robot is able to propel itself and move throughout the body of water, both on the surface and underwater, and the camera unit functions both on the surface and underwater. The robot optimizes the cleaning cycle of the body of water utilizing deep learning techniques. The robot has localization sensors and software that allow the robot to be aware of the robot's position in the pool. The camera is able to send its video feed live over the internet, the processing is performed in the cloud, and the robot sends and receives data from the cloud. The processing utilizes deep learning algorithms, including artificial neural networks, that perform video analytics.

A method for cleaning a region of a pool, the method may include moving a pool cleaning robot along a cleaning path that covers the region while acquiring, at first different points of time and by a sensing unit of the pool cleaning robot, first images of first scenes, at least one first scene at each first point of time; wherein the acquiring of the first images is executed while illuminating the first scenes by the pool cleaning robot; detecting, in at least one first image, illumination reflected or scattered as a result of the illuminating of the first scenes; removing from the at least one first image information about the illumination reflected or scattered; determining, based at least in part of on the first images, first locations of the pool cleaning robot; and wherein the moving is responsive to the first locations of the pool cleaning robot.

Apparatus and methods for counteracting, e.g., drift of automatic swimming pool cleaners are detailed. In particular, a drifting cleaner may recover its movement by altering traction speed of the motive element(s) on one side of its body. Such alteration may occur when the cleaner is travelling along a generally horizontally-oriented pool bottom, climbing up or down a wall, or otherwise moving within a pool.

Automatic swimming pool cleaners may include cable storage systems for storing an electrical cable on, in, or near a body of the automatic swimming pool cleaner. Some cable storage systems may include a cable storage device on the body of the automatic swimming pool cleaner and/or on a cover for the body of the automatic swimming pool cleaner. Cable storage systems may additionally or alternatively include a cable storage device on the electrical cable. The automatic swimming pool cleaners may be configured and balanced to be supported by their rear portions essentially upright when stored.

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 pool cleaner for use in a pool may include a housing, a driving assembly, a traction assembly, and a filtration assembly. The driving assembly may include an inlet conduit configured to receive pressurized water, an impeller in fluid communication with the inlet conduit, an outlet conduit in fluid communication with the impeller, and an outlet nozzle coupled to the outlet conduit and may be configured to eject the pressurized water upward from the housing and into the pool in a parallel or oblique ejection direction relative to a vertical axis. The traction assembly may be coupled to the impeller to drive the housing across the pool and the filtration assembly may be configured to filter water from the pool.

A pool cleaner for cleaning a pool, the pool cleaner may include a filtering element for filtering fluid; at least one sensor for sensing an actual yaw of the pool cleaner and an actual orientation of the pool cleaner; at least one steering element that is configured to move the pool cleaner along a cleaning path, during a cleaning process of segments of multiple sidewalls of the pool; wherein the cleaning path mostly includes substantially horizontal cleaning path segments that have a cleaning path segment yaw that is a substantially horizontal yaw; wherein the certain region is fully submerged; and a controller that is configured to control the at least one steering element, based on the actual yaw of the pool cleaner.

Cleaning of a swimming pool may be facilitated by systems and methods for mapping a pool environment. Such mapping may occur in three dimensions when appropriate. At least some of the systems may include an apparatus for light detection and ranging (LIDAR) tethered to an automatic swimming pool cleaner.
