The cleaning and sweeping vehicle adopts a structure of two central sweeping plates and a central wide suction nozzle (with a built-in high-pressure water spray bar), combined with left and right high-pressure side spray bars, to form a wide washing and sweeping belt. It can complete a complete set of operations such as road cleaning, road washing, high-pressure cleaning, low-pressure cleaning, garbage collection, sewage recycling, etc. in one go, which is equivalent to the synchronous work of the road sweeping vehicle, sprinkler vehicle and high-pressure cleaning vehicle, without the need for additional cleaning equipment, greatly improving work efficiency
