Thus, not only the service station forecourt is quickly cleaned. In one hour, a walk-behind machine can clean 3375 to 4700 square metres. Purchasing a vacuum sweeper is worthwhile from an area of 300 square metres. Because the operator walks with the sweeper as it is pushed around, they are also called 'walk-behind machines'. They are somewhat wider than sweepers, but just as ergonomical, and (with the right equipment) they can clean the tight bends and corners on the forecourt just as well. During the sweeping process, the vacuum sweeper swirls up the dirt with a roller brush, vacuums it by means of a suction turbine (blower) and separates it in a filter system. These machines achieve a sweeping performance of up to 4725 square metres an hour.
The next performance level is the vacuum sweeper. For middle-sized areas: Push vacuum sweepers
