Automatic cleaning device for high-wall building

The invention relates to the field of building outer wall cleaning, and discloses a high-wall building automatic cleaning device which comprises a framework and a controller, a cleaning mechanism is arranged on one side of the framework and used for cleaning the outer surface of a high-wall building, moving arms are rotationally connected to the four corners of the other side of the framework correspondingly, and the moving arms are controlled by a micro-motion mechanism; the movable arms are used for achieving small-range accurate movement of the automatic cleaning device, and the outward extending ends of the movable arms are provided with vacuum adsorption devices correspondingly and used for achieving fixation of the automatic cleaning device and the outer surface of the high-wall building and air injection buffering after large-range movement. The large-range moving mechanism controls the cleaning device to perform regional movement, and the micro-motion mechanism is matched with the vacuum adsorption de
