The special sweeper type BROCK VS7 has a high-pressure rear grit suction unit with rotating nozzles, side suction and hot water system as well as an additional water tank of 2,450 litres. The sweeper has a total water volume of 4,050 litres.
The special feature of this VS7 is the oil residue removal in the width of the vehicle, which was certified by Dekra according to the requirements of traffic surface cleaning and oil removal on traffic surfaces for machines and equipment, both with hot and cold water.
A low-pressure water bar is installed in the front area, which is used to bring a chemical additive on the road to bind oil and other substances. Afterwards, the high-pressure rear grit suction washes and removes the oil, and the road surface is cleaned pore-deep in only one step. For smaller jobs, the machine is equipped with an additional hand tool for removing oil tracks.
