The movable seat 31 has a base plate 311, a pivot motor 312 disposed on the base plate 311, a pivot shaft 313 extending along the left-right direction D2 and connecting the pivot motor 312, and a housing 314 disposed on the base plate 311 and covering the pivot motor 312. The first cleaning arm 32 is pivotally disposed on the movable base 31 and can swing in the front-back direction D1. The first cleaning arm 32 has a pivoting portion 321 fixedly sleeved on the pivoting shaft 313, an arm portion 322 obliquely extending upward from the pivoting portion 321 along the left-right direction D2, four first air inlet holes 323 formed in the arm portion 322, and a first air outlet hole 324 formed in the arm portion 322 and correspondingly communicating with the first air inlet holes 323 and opening downward. The first air outlet 324 is an elongated opening extending along the length of the arm 322. The pivot motor 312 can drive the pivot shaft 313 to rotate and drive the first cleaning arm 32 to pivot, so that the first cleaning arm 32 can swing in the front-back direction D1. The first cleaning elements 33 may be fan-shaped nozzles, for example, which are arranged side by side below the arm portion 322 of the first cleaning arm 32, and the fan-shaped nozzles have knife-shaped openings for spraying the high-pressure first water jet spray 331 to the vehicle 1 for cleaning, and the effective spraying range of the first water jet spray 331 is shown by dotted lines.
