Dongfeng 20 m³ Combined Jetting & Vacuum Truck

The Dongfeng Tianlong 20 m³ Combined Sewer Jetting & Vacuum Truck is designed for heavy-duty sewer cleaning, sludge removal, and sewage collection. It combines high-pressure water jetting with powerful vacuum suction, allowing the vehicle to clear stubborn pipeline blockages and collect sewage, sludge, and sediment efficiently. The large dual-compartment tank provides approximately equal capacity for clean water and sewage, with an interconnected design for greater operational flexibility. A reinforced 8 mm tank structure, heavy-duty hose reel, and practical working platform enhance durability for intensive use. With its large capacity and integrated cleaning system, this sewer jetting and vacuum truck is well suited for municipal drainage networks, industrial facilities, sewer maintenance, and other demanding sanitation operations.

Why Choose Us for Your Special Purpose Vehicle?
Choosing the right special purpose vehicle supplier is not only about finding a competitive price—it is about receiving a vehicle that truly matches your local regulations, operating conditions, payload requirements and business needs. As a professional manufacturer and exporter, we provide factory-direct pricing together with complete one-stop service, helping customers reduce purchasing risks, communication costs and delivery delays.
We can customize the chassis brand, engine power, emission standard, left-hand or right-hand drive, body dimensions, working system and optional equipment according to your application. Whether the vehicle will be used for construction, logistics, municipal services, mining, agriculture or emergency operations, our technical team will recommend a practical and cost-effective configuration rather than simply selling a standard model.
Every vehicle is produced under a controlled manufacturing process and undergoes inspection, functional testing and road testing before delivery. Customers can receive production updates, detailed photos, operation videos and final inspection records. Factory visits and independent third-party inspections are also welcome. Applicable certifications, export documentation, shipping arrangements and customs-related documents can be prepared according to the destination market and project requirements.
Our service continues after delivery. We provide operation guidance, technical support, spare-parts assistance and troubleshooting to help customers keep their vehicles working efficiently.
