1. A method for treating a vehicle having at least one outer surface with an apparatus including at least two treatment brushes configured to be guided along a path on the at least one outer surface, the method comprising:
(a) adjusting an angle of a treatment brush of the at least two treatment brushes, in particular a rotating treatment brush, relative to a vertical, in at least one predetermined angular range at least one of parallel and perpendicular to the outer surface;
(b) guiding the treatment brush along the at least one outer surface on a path during the treatment process;
(c) monitoring the angle of the treatment brush to the vertical at least one of parallel and perpendicular to the outer surface during step (b); and
(d) adapting the path of the treatment brush if a deviation of the monitored angle of the treatment brush from the at least one predetermined angle range is determined in step (c), wherein adapting the path comprises separating the treatment brush from the vehicle, and wherein separating the treatment brush is only performed for the treatment brush of the at least two treatment brushes for which the deviation of the monitored angle is determined.
