HOWO 6x4 20,000L Sewer Cleaning & Vacuum Truck
The HOWO 6×4 20-Cubic Meter Sewer Cleaning and Vacuum Truck from TWL is engineered for demanding sanitation and industrial waste-handling tasks. Built on a durable 6×4 chassis and powered by a 380 HP Weichai engine, this truck delivers strong performance, excellent payload support, and long-term durability.
Its 20 m³ tank system—featuring a 5 m³ clean water tank and a 15 m³ sewage tank—uses high-strength carbon steel and can be fully customized to meet project-specific requirements. The high-pressure cleaning system supports both domestic and imported pump options, offering adjustable performance for municipal sewer lines, industrial pipelines, and emergency applications. The vacuum system ensures powerful suction with a vertical lift of ≥ 8 meters, making it suitable for handling sludge, slurry, and high-density waste.
With a user-friendly layout, hydraulic self-dumping tank, observation windows, ABS braking, high-reliability axles, and all-terrain tires, this model is tailored for efficient operation and reduced maintenance. TWL provides complete customization, competitive factory pricing, and technical support to ensure reliable service for municipalities, sanitation companies, factories, construction firms, and environmental cleanup teams.
