A cleaning apparatus is used for a carrier and a model is fixed on the carrier. The cleaning apparatus includes a case body, a sprinkling unit, a switching valve, and a rotating mechanism. The case body has an opening disposed at a top thereof, an outlet disposed at a bottom thereof, and a receiving space disposed between the opening and the outlet. The sprinkling unit is installed in the case body and has plural nozzles configured corresponding to the receiving space. The switching valve is installed at the outlet to open or close the outlet. The rotating mechanism is configured corresponding to the opening and connected to the carrier and is able to drive the carrier in which the model passes through the opening and is disposed in the receiving space. Thus, the safety, stability, and convenience of the model clean-up are improved.
