Abstract: An automatic pool cleaner includes a housing, a filtering module, and an out-of-water detection module. The housing defines a water inlet and a water outlet; The filtering module is configured to filter fluid from the water inlet to provide filtered fluid. The out-of-water detection module comprises a floating unit and a sensing unit, which can make the floating unit move between the first and the second positions according to whether the pool cleaner is above the waterline. The sensing unit identifies the position of the floating unit and outputs a first signal or a second signal to the pool cleaner, thereby determining whether the pool cleaner is above the water surface.

Abstract: A robot swimming pool cleaner includes a housing. The housing is provided with a water inlet and a vector nozzle, a drainage power mechanism is arranged inside the housing, a top part of the vector nozzle is a bending portion, a bottom part of the vector nozzle is a vertical portion, and the vertical portion is in transmission connection with a rotation power mechanism; the control mechanism is in electric signal connection with the rotation power mechanism, and by controlling the rotation angle of the vector nozzle, the operating posture and trajectory of the robot swimming pool cleaner may be adjusted by cooperating with a driving wheel. The swimming pool bottom and the swimming pool wall may be effectively cleaned.

Abstract: Disclosed are a water surface profile cleaning method and system of a robot swimming pool cleaner. The method includes: obtaining driving wheel power information according to the sensing information of the first water surface sensor and the sensing information of the second water surface sensor; obtaining cleaning route information of a robot swimming pool cleaner according to the driving wheel power information and preset angle information; and cleaning, by the robot swimming pool cleaner, a water surface profile according to a cleaning route. In the present application, a moving track problem and an up and down movement cleaning problem of a robot swimming pool cleaner at a water surface profile can be systematically solved.
