The cleaning and suction vehicle (also known as the high-pressure cleaning and suction dual-use vehicle) is a special vehicle based on the modification of Class II automobile chassis, which works in conjunction with high-pressure water flow dredging and negative pressure vacuum suction dual systems to specifically handle complex pollutants such as municipal pipeline blockages, septic tank siltation, and construction site mud. Its core positioning is "first connect, then suction, one vehicle solution", replacing the traditional "high-pressure cleaning vehicle+suction truck" multi vehicle cooperation mode, solving the pain points of low pipeline dredging efficiency and secondary pollution, and is the core equipment for municipal sanitation, property cleaning, and engineering construction.
