Overview
The National-V Multifunctional Sweeper Washer represents advanced Chinese road maintenance technology, meeting strict National-V (China 5) emission standards for diesel engines. Combining three core functions—mechanical sweeping, high-pressure washing, and vacuum suction—it significantly improves cleaning efficiency while reducing environmental impact. Municipalities and contractors favor this equipment for its versatility in handling diverse debris, from fine dust to larger particles. Unlike traditional sweepers, this model integrates a closed-loop water circulation system to minimize water consumption. Its compact design allows operation in narrow urban streets while maintaining a large 8–12m³ debris capacity. The vehicle typically uses a Dongfeng or Foton chassis with 4×2 or 6×4 drivetrains for stable performance.
Structure and Working Principle
The sweeper washer comprises four subsystems: a mechanical sweeping module with side brushes, a high-pressure washing unit (15–20MPa), a debris collection hopper with cyclone filtration, and a wastewater recovery system. The side brushes direct debris toward the center, where a main roller brush lifts particles into the hopper while simultaneous water jets loosen stubborn deposits. Key innovations include an automatic height-adjusting sweeping head that maintains optimal contact pressure and a CAN-bus control system for real-time monitoring. The National-V compliant engine (e.g., Yuchai or Weichai) powers both propulsion and hydraulic systems, with separate circuits for sweeping, washing, and suction to ensure consistent performance.
Key Features
Emission compliance stands out, with particulate matter (PM) emissions below 0.025g/kWh—60% lower than previous standards. The dual-mode operation allows switching between water-intensive deep cleaning (6–8L/m²) and water-saving dry sweeping (0.5–1L/m²), adapting to local water restrictions. Advanced features include an anti-collision sensor system for the side brushes, automatic water recycling achieving 90% reuse rate, and optional telematics for fleet management. Noise levels are kept below 72dB(A) through optimized fan designs and soundproofed compartments, making it suitable for nighttime operations in residential areas.
Application Areas
Primarily deployed by municipal sanitation departments for daily street cleaning in Tier 1–3 Chinese cities. Airports use specialized versions with magnetic debris detection for runway safety. Highway operators employ these vehicles for median and shoulder maintenance, where their 80km/h travel speed reduces traffic disruption. Industrial applications include mining access roads (with reinforced filters for abrasive dust) and port container yards. Some models integrate snowplow attachments for northern regions, demonstrating year-round utility. Export markets in Southeast Asia and Africa value its adaptability to both paved and unpaved surfaces.
Maintenance and Precautions
Daily checks should focus on brush wear (replace at 30% remaining height), water filter cleanliness, and hydraulic hose integrity. The wastewater tank requires biweekly sterilization to prevent microbial growth. Use only manufacturer-approved replacement parts to maintain emission compliance. Critical precautions include avoiding acidic cleaning agents that corrode stainless steel components and preventing diesel particulate filter (DPF) clogging through regular regeneration cycles. Winter operation demands complete water system drainage below 0°C to prevent freeze damage. Always engage the parking brake before activating sweeping functions on slopes.
B2B Procurement Guide
When sourcing these vehicles, verify the manufacturer's National-V certification documents and request third-party emission test reports. Compare tank capacities—standard models offer 5–8m³ debris and 1.5–3m³ water storage. Essential add-ons include automatic lubrication systems and emergency stop buttons. Lead times typically range 45–90 days post-order. Negotiate service contracts covering at least 12 months or 2,000 operating hours. For large fleets, consider localized maintenance training programs. Payment terms commonly involve 30% deposit with balance upon delivery, though financing options through Chinese export banks are available for international buyers.
