Background technique

Window cleaning machines are mainly used for cleaning windows and exterior walls of buildings. The traditional window cleaning methods currently on the market are mainly by hanging suspension equipment on the exterior walls of buildings, and window cleaning workers perform high-altitude operations on the suspension equipment. Window cleaning work, this type of high-altitude window cleaning is too bulky and requires a large suspension device to support the operation. Ordinary families cannot afford window cleaning service fees, and high-altitude operations are dangerous and unsafe, and it is inconvenient to replace cleaning water. The efficiency of window cleaning is low. For this kind of problem, other types of window cleaning machines such as household window cleaning machines and household window cleaning robots have been developed successively on the market.
