[Dongfeng Tianjin Dual-Mode (Dry/Wet) Vacuum Sweeper] Built on the Tianjin chassis with a 4.7-meter wheelbase, powered by a Cummins engine delivering 230 horsepower, equipped with an 8-speed transmission, air conditioning, electric windows, central locking, and 10.00 steel-belted tires. Its superstructure features two operational modes: 1) Washing & Sweeping Mode—ideal for municipal urban trunk roads and elevated highway surfaces; features dual center-mounted sweeping brushes, side-mounted high-pressure spray bars, and a rear-mounted roller-suction unit with additional side high-pressure spray bars—effectively widening the cleaning path and achieving a single-pass cleaning efficiency of over 95%; 2) Vacuum-Only Mode—designed for dusty surfaces where water use is impractical; employs pure negative-pressure suction with unidirectional airflow, ensuring dust enters but does not escape, eliminating secondary dust generation and achieving zero PM2.5 emissions. Through multiple generations of innovation and refinement, vacuum sweepers have evolved into today’s advanced dual-mode (dry/wet) vacuum sweepers—delivering powerful cleaning performance and broad application versatility. Moving forward, in response to evolving market demands, we will continue innovating to design and deliver high-quality, purpose-built products. A steel-wire roller brush is integrated inside the rear-mounted suction unit to effectively remove muddy and stubborn road contaminants, complemented by high-pressure water jets that break down hardened deposits, oil stains, and other difficult-to-remove debris. The vehicle features dual center-mounted sweeping brushes compatible with dry-sweeping operations; its rear-mounted high-pressure reel enables versatile applications—including curb cleaning, removal of small advertisements, vehicle washing, and landscape irrigation.
