Provided is a suction self-moving device, provided with a base (100), a travel unit (300), and a function unit (200); the bottom of the base comprises a cavity (110); the cavity (110) is in communication with a vacuum source (400); the outer periphery of the cavity (110) is provided with a sealing assembly used for sealing with the suction surface; after sealing between the sealing assembly and the suction surface, a vacuum chamber is formed with the cavity (100); the sealing assembly is connected to the bottom of the base by means of a flexible retractable member (530). In the present invention, a flexible retractable member is disposed between the sealing assembly and the base; thus the vacuum chamber has an improved seal, and the travel of the suction self-moving device is not impeded. |
