PROBLEM TO BE SOLVED: To provide a high-pressure washing vehicle in which the delivered length of a hose is easily and accurately measured. SOLUTION: This high-pressure washing vehicle comprises a washing nozzle for jetting a washing water, the hose for guiding the washing water to the washing nozzle, and a hose reel around which the hose is wrapped. The high-pressure washing vehicle further comprises two guide rollers 94 for guiding the hose in a predetermined direction by rotating when the hose is delivered or wrapped around and a measuring device for measuring the delivered length of the hose from the number of rotations of the guide rollers 94. Two gears 99 meshed with each other are installed at one ends of the two guide rollers 94, respectively. The two guide rollers 94 are rotated by the two gears 99 in synchronism with each other. The measuring device has an encoder 87. The encoder 87 is attached to one end of one of the two guide rollers 94. The encoder 87 detects the number of rotations of the one guide roller 94.
