The building curtain wall is developed rapidly in China for 20 years due to the advantages of attractiveness, energy conservation, easiness in maintenance and the like, and the construction of the building curtain wall in China is about ten million square meters every year. However, due to long-term exposure to sunlight and wind and rain, and the retention of carbon dioxide, carbon monoxide, sulfur dioxide, sulfur trioxide, various chlorides and oil fume on the building surface, once mixed with rainwater and moisture, the building can be attacked by acidity or alkalinity. If the installed curtain wall is not regularly cleaned and maintained throughout, these acids and alkalis will penetrate into the building surface, corroding the surface and structure of the curtain wall, thus requiring regular cleaning and maintenance of the building curtain wall.

In the initial stage of curtain wall cleaning, manual cleaning is almost completely adopted. Over time, some domestic enterprises have been looking at developing curtain wall cleaning equipment for high-altitude cleaning operations to replace labor. In the existing curtain wall cleaning equipment, the traveling wheels are in contact with the curtain wall, and the equipment can travel on the curtain wall under the driving of the lifting mechanism. However, the friction between the road wheels and the curtain wall is not constant, and once the friction is too large, the curtain wall may be damaged.
