ABSTRACT:
An automatic outer wall cleaning machine for a high-rise building comprises a shell, an actuator, two drum brushes and a plurality of suction cup units, in which the shell can be suspended outside high-rise buildings with cables for raising and lowering, a guide rail is placed at each lateral side in the shell to provide a support for a motor which is controlled by an actuator for upward and downward displacement, the motor's transmission shaft is extended out of the shell through a guide slot and connects to a drum brush at each side, and the drum brush is protected by a shield. Each drum brush is designed with a sleeve along its central line for insertion of the transmission shaft, and water outlets connecting to each other are designed therein. An end of the sleeve is fitted with a rotary connector for feeding of water. By rotation, raising and lowering of the drum brushes and feeding of water jet into the sleeve of the drum brushes, cleaning action is performed. Each corner of the shell is integrated with a suction cup unit with setoff adjustment to secure the machine firm to the outer wall, and an air dryer is integrated to the drum brush for air drying after water cleaning.
