The present disclosure relates to the technical field of swimming pool cleaning, and more specifically, to a method for searching a position for wall climbing underwater by a pool cleaning robot. The method comprises: the swimming pool cleaning robot rotates one circle underwater to obtain data of the perimeter of a swimming pool; it is determined whether the cleaning robot is now facing a wall in its current orientation based on the perimeter data; if not, a wall closest to the swimming pool cleaning robot is selected from the perimeter data and the robot is controlled to rotate to directly face the closest wall. In the end, the robot is controlled to move towards the closest wall. According to the present disclosure, in case that the robot needs to climb a wall for wall cleaning or go ashore, the robot can rapidly climb the wall.

The present disclosure provides a cleaning device. The cleaning device includes a cleaning device body, a drive mechanism, a filtering mechanism, a liquid inlet portion, a liquid outlet portion, and a mode switching member. The drive mechanism and the filtering mechanism are disposed on the cleaning device body. The liquid inlet portion includes at least a first water inlet. The first water inlet is provided on the cleaning device body. The liquid outlet portion includes at least a first water outlet. The first water outlet is provided on the cleaning device body. The first water inlet, the filtering mechanism, the drive mechanism, and the first water outlet sequentially communicate to form a first water path. The mode switching member is configured for the cleaning device to be switched between a position on a liquid surface and a position under the liquid surface.

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.

Disclosed are a pool cleaning device and a corresponding control method. The pool cleaning device includes: a fluid ejecting unit including a fluid channel through which water flows and a vector nozzle, an inlet of the vector nozzle being rotatably connected with the fluid channel; a first driving unit configured to drive water to be ejected from an outlet of the vector nozzle via the fluid channel; a housing, with at least two discharge openings arranged thereon; and a second driving unit configured to drive the vector nozzle to rotate so that the outlet of the vector nozzle is at least partially aligned with one of the at least two discharge openings.

An underwater robot and a control method therefor. The underwater robot includes a robot main body, wherein a dirt suction port is provided at bottom of the robot main body, a first water outlet is provided on top of the robot main body in communication with the dirt suction port, a second water outlet is further provided at bottom of the robot main body in communication with the first water outlet, and the second water outlet is located on a side of the dirt suction port close to a front end; and a water-pumping mechanism and an escape mechanism provided in the robot main body. By means of the underwater robot and the control method therefor, the obstacle crossing capability of the underwater robot is improved.

The present disclosure provides a cleaning device, including a cleaning device body, a liquid inlet portion, a liquid outlet portion, a filtering mechanism, and a mode switching member. The filtering mechanism includes at least a filtering box. The filtering box includes at least a filtering box opening for water surface cleaning, a filtering box roller brush assembly, and a drive gear. The filtering box roller brush assembly is disposed at the filtering box opening for water surface cleaning. The drive gear is configured to drive the filtering box roller brush assembly to rotate. The mode switching member is configured for the cleaning device to be switched from a first motion state to a third motion state via a second motion state. A posture of the cleaning device in the first motion state is substantially identical to a posture of the cleaning device in the third motion state.

The present application provides a pool automatic cleaning device, including: a main body; a moving mechanism which is located on a side of the main body and enables the pool automatic cleaning device to move; and a guiding structure which is disposed on the moving mechanism or the main body and protrudes from the moving mechanism or the main body; wherein during a movement of the pool automatic cleaning device, in a case where the guiding structure touches a pool wall, a friction force caused by the touch is able to cause the guiding structure to rotate. The present application may control the pool automatic cleaning device to keep the main body closely attached to the pool wall when moving along a pool edge through the guiding structure, thereby improving the mapping quality and the cleaning coverage rate in the pool edge region.

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 method for a swimming pool robot to clean along a wall edge, including when a task of cleaning along the wall edge is performed, determining a distance between the swimming pool robot and a swimming pool wall; determining whether the distance between the swimming pool robot and the swimming pool wall matches a target distance when moving along the wall edge, and when the distance does not match the target distance, controlling the swimming pool robot to turn a preset angle towards the swimming pool wall, and driving the swimming pool robot to move forward; determining whether the guide device touches the swimming pool wall, and when the guide device touches the swimming pool wall, driving the swimming pool robot to move forward, until the distance between the swimming pool robot and the swimming pool wall matches the target distance.
