METHOD AND APPARATUS FOR CLEANING HIGH-FUNCTION PAVED SURFACE

PROBLEM TO BE SOLVED: To provide a cleaning apparatus, etc., capable of easily cleaning a high-function paved surface without carrying out traffic control. SOLUTION: The cleaning apparatus A includes a jet nozzle 5 disposed on a vehicle body V capable of traveling, a tank 4 which supplies a cleaning solution to the jet nozzle 5, a supply pipeline 10D disposed between the jet nozzle 5 and the tank 4, a pressure pump 12 disposed in the middle of the supply pipeline 10D, a suction chamber 6 having a suction port 6a on its lower end, the suction port 6a being disposed at the rear of the vehicle body V than the jet nozzle and open to a paved surface Fa on which the vehicle body V travels, a pressurized air jet 6b which is provided to jet pressurized air from the periphery of the open suction port 6a toward the paved surface Fa to partition the suction chamber 6 from the outside air, and a negative pressure generator 7 which generates a negative pressure inside the suction chamber.
