When brush-washing a vehicle in a vehicle washing facility equipped with a portal (1,2) which carries roof and side brushes (6,11), the portal is driven along a vehicle standing area (4) at a first, relatively low speed immediately after a start or restart. Subsequent to the passage of a given time period, the portal drive speed is increased, successively or incrementally, to a relatively high, second speed, provided that the force with which the roof and/or the side brushes (6,11) abut the surface of a vehicle undergoing a brush wash during this time period remains between preselected maximum and minimum values. |
