It is usually used to clean the exterior walls of buildings, roads, and vehicles. High-pressure cleaning vehicles have the advantages of efficient cleaning, saving time and manpower, environmental protection and energy saving, and safe cleaning. High-pressure cleaning vehicles are easy to operate. When working, operators can operate in a safe position, which can effectively avoid direct contact with dirt and chemical cleaning agents.
[0003] At present, a road cleaning vehicle uses a high-pressure water pump to generate a high-pressure water flow, and cleans the road surface through a water spray structure installed on the front of the vehicle.
