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.

The present disclosure provides a positioning method and system for an underwater cleaning robot, an apparatus, and a storage medium, and relates to the field of cleaning robots. The method includes: obtaining position information of the underwater cleaning robot relative to a base station; and determining a position of the underwater cleaning robot based on position information of a positioning sensor connected to the base station and the position information of the underwater cleaning robot relative to the base station. The method can improve the positioning accuracy of the underwater cleaning robot to a certain extent.

This application discloses a cleaning device control method and a cleaning device. The method comprises: controlling the cleaning device to move to a starting point at which the cleaning device moves along an edge of a target water region; controlling the cleaning device to move along the edge of the target water region from the starting point by at least one round; constructing a target map of the target water region, wherein the target map comprises a map of at least one of a bottom of the target water region or a water surface of the target water region; and performing path planning on the target water region based on the target map and controlling the cleaning device to clean the target water region in a process of moving along a planned path.

The present disclosure provides a locomotion apparatus used in liquid. The moving apparatus includes a buoyancy cavity disposed in the locomotion apparatus, and is configured to accommodate gas or liquid; and a first regulation part disposed in the locomotion apparatus, and is configured to regulate a volume of the gas or the liquid in the buoyancy cavity; when the locomotion apparatus is switched from the sidewall of a swimming pool to the liquid surface, the volume of the gas or the liquid in the buoyancy cavity is regulated by the first regulation part to increase the buoyancy force applied to the locomotion apparatus.

The present disclosure provides a cleaning device, including: a cleaning device body; a filtering mechanism; a cleaning cavity disposed at a front portion of the cleaning device body and configured to accommodate at least one first cleaning part; a liquid inlet portion; a mode switching member configured to adjust a pose of the cleaning device, enabling the cleaning device to be switched between a first motion state and a third motion state, where when the cleaning device is in the first motion state, the liquid inlet portion is located under a water surface, and the cleaning device performs underwater cleaning, and when the cleaning device is in the third motion state, the liquid inlet portion is at least partially located above the water surface, and the cleaning device performs water surface cleaning; and a main water pump configured to generate a suction force.

Disclosed are a method for a pool cleaning apparatus to move sideways and a corresponding pool cleaning apparatus. The method may include: if the condition for the pool cleaning apparatus to move sideways is satisfied, controlling the pool cleaning apparatus to enter a sideways movement operating mode, so that the pool cleaning apparatus moves towards one side, and in the sideways movement operating mode, controlling a discharging pump to provide a thrust to a side opposite the one side; in the sideways movement operating mode, controlling the pool cleaning apparatus to drive the driving wheels on both sides at a target rotational speed difference, so that the pool cleaning apparatus is tilted towards the one side.

A self-propelled pool cleaner may be operable in a swimming pool or spa. Systems and methods may allow for the pool cleaner to find or locate a docking station within the swimming pool or spa, may allow the pool cleaner to properly dock with the docking station, and/or may allow for the pool cleaner to navigate to a docking station from anywhere within the pool. Docking of the pool cleaner with the docking station may not require physical handling by a user or pool owner.
