Abstract: The present application provides an automatic pool cleaning device and a control method thereof. The method comprises: controlling the device to move from a first position on a pool bottom to a second position on the bottom surface of the pool and performing positioning there to obtain first positioning information, wherein at least a first part of the movement path from the first position to the second position is along an edge of the pool; controlling the device to move from the second position to a third position on the bottom surface and performing a cleaning operation on the bottom surface; controlling the device to move from the third position to a fourth position on the bottom surface and performing positioning there to obtain second positioning information; and controlling the device to move from the fourth position back to the first position based on the first and second positioning information.

Abstract: The present disclosure provides a map-building method for an automatic pool cleaning device, comprising: controlling the automatic pool cleaning device to travel one circle or longer than one circle along a pool edge on a pool bottom or a water surface, and during the travel along pool edge, collecting pool edge information in real-time to obtain point cloud data for a first path, wherein a path of the travel along the pool edge is the first path; controlling the automatic pool cleaning device to continue traveling along the pool edge from an ending point of the first path and continue to collect pool edge information in real time until a first predetermined condition is met, thereby obtaining point cloud data for a second path, wherein a path along the pool edge starting from the ending point of the first path is the second path; and generating a closed pool-edge map.
