Automatic swimming pool cleaners for swimming pools and spas may automatically schedule, defined, and/or plan a future cleaning cycle for the automatic swimming pool cleaner. The automatic swimming pool cleaner itself may plan the future cleaning cycle without receiving a cleaning order from a user and/or may allow for the pool system to keep the pool or spa clean by itself without relying on an order from the user as traditionally required.

Disclosed herein is a method of detecting stalled state of a dynamic pool equipment unit, comprising receiving a plurality of movement features relating to a dynamic pool equipment unit deployed in a water pool which are captured during a predefined sampling window and comprise (1) motion features of the pool equipment unit, and (2) operational features of electric motor(s) of the pool equipment unit, determining a movement pattern of the pool equipment unit using one or more statistical models applied to the plurality of movement features which are trained to estimate a stalled state of the pool equipment unit in which the pool equipment unit is pitched up and unable to advance on a slopped obstacle in the water pool, and causing the pool equipment unit to stop attempted advance in a current direction responsive to determining that the pool equipment unit is in the stalled state.

A wall collision U-turning method for a swimming pool cleaning robot, a swimming pool edge cleaning method, and an electronic device are provided. The wall collision U-turning method includes: controlling the swimming pool cleaning robot to move toward a wall of a swimming pool based on a preset orientation until the swimming pool cleaning robot collides with the wall of the swimming pool; controlling the swimming pool cleaning robot to move backward relative to the wall of the swimming pool until a spacing distance between the swimming pool cleaning robot and the wall of the swimming pool is sufficient for the swimming pool cleaning robot to perform a U-turn motion; and controlling the swimming pool cleaning robot to perform a U-turn relative to the wall of the swimming pool until the U-turn orientation of the swimming pool cleaning robot after completion of the U-turn is opposite to the preset orientation.

A swimming pool map boundary construction and swimming pool cleaning methods, an apparatus, and an electronic device are provided. A swimming pool cleaning robot is controlled to move forward and backward relative to each preset path in a swimming pool map that covers a swimming pool within a working area defined by the swimming pool, to determine two path endpoints of each preset path, and map boundaries of the swimming pool map are constructed based on the determined two path endpoints of each preset path in the swimming pool map, so that the construction of swimming pool map boundaries is more efficient, reasonable and accurate. Moreover, the swimming pool cleaning task performed based on the swimming pool map constructed by the above method can achieve comprehensive cleaning of the swimming pool and avoid omissions.

The present disclosure provides a method and apparatus for cleaning a swimming pool, and an electronic device and a storage medium thereof. The method includes: controlling a swimming pool cleaning robot to move, with respect to a grid map covering the swimming pool, in a work area defined in the swimming pool to establish a cleaning map including a plurality of cleaning blocks; and controlling the swimming pool cleaning robot to traverse each of the cleaning blocks in the cleaning map to clean the swimming pool. According to the present disclosure, the cleaning regions may be accurately constructed in the map according to the work area in the swimming pool, such that the swimming pool cleaning robot cleans the swimming pool in a quick, efficient, and energy-saving fashion.

The present disclosure provides a method and apparatus for return control of a swimming pool cleaning robot, and an electronic device and a computer storage medium thereof. The method includes: in response to a trigger of a return instruction, acquiring a current position of the swimming pool cleaning robot in a map for a swimming pool; and generating a return path according to a reachable block in the map for the swimming pool, a predetermined return position, and the current position, and controlling the swimming pool cleaning robot to return from the current position to the predetermined return position on the basis of the return path. Therefore, the swimming pool cleaning robot is controlled to automatically return to a designated position of the swimming pool, such that use smartness of the swimming pool cleaning robot is improved, and use experience of a user is enhanced.

An underwater cleaning robot contains a movement device for moving the underwater cleaning robot under water, a cleaning device for cleaning an object located under water, a control device for controlling the movement device and/or the cleaning device and a communication device for receiving and/or transmitting signals from outside the underwater cleaning robot and vice versa. The communication device contains a first ultrasonic transducer for receiving ultrasonic signals transmitted under water and is designed to transmit electrical signals, corresponding to the ultrasonic signals received, to the control device.

The present disclosure relates to the field of underwater robots, and in particular to a controllable sinking and floating swimming pool robot and a sinking and floating control method for a swimming pool robot. The controllable sinking and floating swimming pool robot of the present disclosure includes a sinking and floating control unit configured to control a swimming pool robot to float and sink; a waterline detection unit configured to detect a positional relationship between the swimming pool robot and a waterline of a liquid surface of a swimming pool where the swimming pool robot is located; and a main control unit configured to control a working state of the sinking and floating control unit to enter a floating working state based on detection results to realize a floating of the swimming pool robot.

A system for navigating a dynamic pool equipment unit is disclosed. The system comprises a wireless unit physically connected to the dynamic pool equipment unit deployed in a water pool, allowing the wireless unit to move with the equipment while partially out of the water. The wireless unit includes a first interface for communicating with the equipment unit via a first communication channel, and a second interface for intercepting wireless signals from external stations via a wireless communication channel. A controller navigates the equipment unit towards the external station(s) by measuring the received signal strength indicator (RSSI) of intercepted wireless signals, estimating the direction of the external station(s) based on RSSI analysis, and transmitting movement instructions to the equipment unit to advance in the estimated direction.
