The cleaning and suction vehicle, also known as the sewage dredging and suction dual-purpose vehicle, is a new type of environmental sanitation vehicle that combines the functions of sewage dredging and suction vehicles. The highlight of this vehicle is to clear the blocked areas of the sewage that cannot be reached by human labor, and then absorb the sewage and dirt in the sewage. The sewage and dirt are absorbed into the tank body and then discharged. It uses a domestically leading technology leading sewage suction pump, which has a large suction force and a long suction distance. It is particularly suitable for the suction, transportation, and discharge of sediment in the sewage system, especially for larger objects such as mud, silt, stones, bricks, and substances with low water content. Full suction time of sewage (feces) tank: ≤ 5 minutes, suction lift: ≥ 10 meters. Self suction and self discharge, long service life, fast working speed, and convenient transportation. There are two types of discharge for suction trucks: pressurized discharge and self flow discharge. The suction truck is self suction and self discharge, and the back cover can be opened and self discharge impurities from the tank body. It has high suction efficiency, self suction, self discharge, and direct injection, and is fast and easy to operate
