The road washing and sweeping vehicle has revolutionized the traditional cleaning process by adopting a wash-sweep  approach instead of dry sweeping. The vehicle uses a combination of sweeping brushes and a centralized cleaning and  suction system to perform cleaning, sweeping, and suction simultaneously,  without producing any secondary dust. Additionally,  the centralized negative pressure suction system is powerful enough to collect all the garbage and wastewater from the  road surface in one go, thereby saving the manpower required for cleaning small alleys and backstreets.

To address the problems of dust and difficult-to-clean crevices on pedestrian walkways, the vehicle uses a "wash,  sweep,  and suction" approach that combines sweeping brushes and a centralized cleaning and suction system to quickly clean and  collect garbage from pedestrian walkways and quickly suck in the garbage and wastewater. After the cleaning is  completed, all the garbage and wastewater are taken away, and there is no dust or secondary pollution. Moreover,  the cleaning effect can last for a long time, and the road surface will not be noticeably dusty even after a day or two.

Furthermore, the road washing and sweeping vehicle is fully electric, powered by a top brand battery,  and equipped with an independent fast charging device that can fully charge the vehicle in 2-3 hours. The vehicle can  operate for 6-7 hours continuously,  which is more than enough to meet the normal cleaning requirements of commercial streets. The vehicle has a panoramic  front view, a streamlined appearance, and an electrophoretic paint process,  which makes it aesthetically pleasing and enhances the city's environmental image.

In summary,  the road washing and sweeping vehicle is an innovative solution to traditional cleaning methods. It combines sweeping  brushes and a centralized cleaning and suction system to perform cleaning, sweeping, and suction simultaneously,  effectively solving the problems of dust and difficult-to-clean crevices. Moreover, the vehicle is fully electric,  has a long operating time, and an aesthetically pleasing appearance,  making it a great addition to any city's environmental image.
