The invention belongs to the technical field of car washing, and particularly relates to a medium switching device and a car washing cleaning system. The medium switching device comprises a switching valve body and a valve element. A medium inlet and a medium outlet are formed in the two ends of the switching valve body. The valve element is arranged in the switching valve body and provided with a transfer channel, the two ends of the transfer channel are communicated with the medium inlet and the medium outlet respectively, the aperture of the transfer channel is smaller than that of the medium outlet, and the valve element can reciprocate between the medium inlet and the medium outlet. The outlet end of the valve element can move into the medium outlet or move into the valve body from the medium outlet so that the medium can be output through the transfer channel or the medium outlet. According to the medium switching device provided by the invention, the output part can be automatically switched according to the input medium, so that the input medium is output at proper pressure, medium switching can be completed without operation, and the medium switching device is simple and convenient and has good practicability.
