Disclosed are a control method for a robotic pool cleaner and a robotic pool cleaner. When the robotic pool cleaner satisfies a wall-climbing condition, it climbs a wall to travel toward a waterline. During the wall-climbing process, when the robotic pool cleaner is partially or completely located in a first wall area on a pool wall and cannot continue traveling toward the waterline, it moves in a direction opposite to a wall-climbing path to move away from the first wall area. A surface of the first wall area forms an open cavity on the pool wall, and the open cavity is capable of accommodating at least a preset proportion of the robotic pool cleaner's body. This solution can clean at least a portion of the pool wall to complete a cleaning task as much as possible while reducing energy consumption and improving cleaning efficiency.

An automatic power-on/off structure for rotation-and-flip operations of a night-vision device is provided, relating to the technical field of night-vision devices. The structure includes a frame, two pivot arms, two night-vision scopes, two magnets, and two Hall sensors. Through the interaction between the magnets and the Hall sensors, i.e., a non-rigid contact, the structure enables automatic powering on of a night-vision scope when in use and automatic powering off when not in use. Specifically, when a pivot arm drives the corresponding night-vision scope to rotate to a certain angle, the magnet enters the sensing range of the Hall sensor, thereby triggering a signal to power on that night-vision scope. Conversely, when the pivot arm drives the night-vision scope away from the sensing range, that scope is automatically powered off. In addition, the pivot shaft connecting the pivot arm and the frame includes an adjustable damping feature, and sealing rings are provided at the contact portions to ensure dustproof and waterproof performance, allowing the structure to adapt to a wide range of operating conditions.
