[0053] The working principle of the present invention is:

[0054] First, the driver drives into the car wash channel according to the prompts. When passing the top brush device 4 and the skirt brush device 3, the top of the bus and the lower part and the skirts on both sides of the bus are brushed respectively. During the brushing process, the first spray device 5 sprays the washing liquid on the bus body at the same time to improve the cleaning effect of the bus. Then the bus drives into the washing channel 1. At this time, the head, tail and both sides of the bus are cleaned and brushed respectively by the side brush device 2. Finally, the bus is rinsed by the second spray device 6 to remove the residual stains and surface washing liquid on the surface of the bus. Then the bus can drive out from the other end of the washing channel 1.
