Traditional cleaning methods have failed to meet current market demand, and while using conventional cleaning robots can clean the same plane or the same row of photovoltaic panels, the investment is huge, the burden on the power station is heavy, and the cleaning quality is still difficult to guarantee. Therefore, a professional photovoltaic cleaning robot needs to be designed.

[0004] The existing photovoltaic cleaning robot walks on the surface of the photovoltaic panel, and the walking mechanism is usually attached to the surface of the photovoltaic panel by point contact pressure of the suspension system. During operation, the attachment surface is unstable on uneven surfaces, which can affect the walking and cleaning effect, and even cause the robot to fall. SUMMARY
