A vehicle cleaning system includes a drive pump, an ejection nozzle and a valve device. The valve device includes an intake passage, a valve that closes the intake passage and accumulates pressure of the fluid supplied to the intake passage, a discharge passage, and an auxiliary mechanism. The auxiliary mechanism generates leakage of the fluid from the intake passage during the pressure accumulation to accumulate pressure with the leakage at a leaked side, opens the valve body based on two pressures accumulated in the intake passage and the leaked side, outputs the fluid, which is pressure-accumulated in the intake passage, to the discharge passage by opening the valve body, and closes the valve body as the fluid is output to the discharge passage to allow for re-accumulation of the pressure in the intake passage.
