Cleaning car common trouble repair

Aug 31, 2023

The washing and sweeping vehicle can be used as a separate sweeping vehicle for road cleaning and suction operations; It can also be used as a high pressure washing vehicle for road surface washing and suction operation; The combination of road cleaning pumping and high pressure flushing can also be used as a washing and sweeping vehicle to achieve a variety of combination choices of cleaning, washing and pumping to meet the various needs of different users, and is widely used in urban trunk roads and viaduct washing and cleaning operations. When you need to perform road cleaning or road cleaning, you can select the road sweeping mode. When spray dust removal is needed, the spray device can be turned on for spray dust removal operation, and the road can be washed at low pressure like a sprinkler.
