The cleaning and sewage suction truck is a core equipment for municipal sanitation. It integrates high-pressure cleaning, efficient sewage suction, and sewage transportation functions, and can one-stop solve the needs of pipe network dredging, septic tank cleaning, road surface cleaning, etc. The vehicle models include various types such as fuel-powered and pure electric. The tank volume is 3-20m³, the high-pressure cleaning pressure is 16-28MPa, and the sewage suction efficiency is more than 10 times that of manual work. It can effectively ensure smooth drainage, improve environmental sanitation, avoid high risks of manual operations, and is widely applicable to multiple scenarios such as municipal administration, residential areas, and construction sites.
