This product adopts a design method that does not require the addition of cleaning solution. The design of the cleaning brush wire is made of multi edged polyethylene ultra soft material, which not only does not damage the anti-corrosion decorative layer on the surface of the steel plate, but also effectively removes different pollutants. At the same time, compared to adding cleaning solution, the cleaning method is more environmentally friendly. To achieve better cleaning results

The front of the carriage is equipped with an automatic guardrail cleaning car with an automatic retractable door. When not in operation, the cleaning device is hidden inside to avoid exposure and improve the service life of the device. The rear installation design of the auxiliary engine makes maintenance and repair convenient, reducing the interference of auxiliary engine vibration and noise on the driver and passengers, and improving the driving and riding comfort of the driver and passengers.
