[0004]

The conventional technique for cleaning the exterior wall surface of a building that relies on manpower by a gondola or swing requires a safety measure as work at a high place. With such a technique, the work posture is such that it is supported by the wire rope suspended from the upper part, so that it is easily affected by the weather such as wind and rain, and stable work is not easy. Such instability results in the inability to perform long-term continuous work, which impairs work efficiency. In addition, in terms of safety and equipment, there is a problem that the height of the target building is limited. On the other hand, since the permanent cleaning robot is applied only to the installation building,
The cost is extremely high and there is generally no alternative cleaning method in case of failure. In addition, since the suction type cleaning robot requires smoothness of the target surface, there are restrictions on the applicable target building, there is a difficulty in versatility, and the application is limited, so the frequency of use is low and the cost is high. There was a problem to be improved such as.

It is an object of the present invention to solve the above problems and to provide a technique capable of effectively cleaning the exterior of a building at low cost.
