This device is suitable for cleaning photovoltaic panels located at high places such as roofs and building roofs.

[0038] When working, the walking component works first, while keeping the position adjustment component above the photovoltaic panel and the cleaning component above the middle of the bottom plate. When the photovoltaic panel is in the middle of the bottom plate, the walking component stops moving, and then the inclination adjustment component adjusts the inclination of the position adjustment component according to the height of the photovoltaic panel at the corresponding point detected. After the adjustment is completed, the cleaning component adjusts the overall height to start cleaning. The position adjustment component works during cleaning, so that the cleaning component works in a predetermined order and speed.
