In a portal-type washing arrangement for vehicles, one of the rotary mountings for a horizontal rotary washing brush is arranged at the lower end of a vertically downwardly hanging swinging arm. The upper end of the swinging arm is connected to a first carriage which is vertically displaceable on a vertical guide rail of the portal assembly. Disposed in the region of movement of the swinging arm is a switching arrangement which controls a control motor. The control motor is connected by way of flexible traction means to the first carriage and to a second carriage which is vertically displaceable on a further vertical rail on the portal assembly. The other rotary mounting of the washing brush is directly and rigidly connected to the second carriage.
