ABSTRACT:
A washing apparatus for an automotive vehicle having at least one washing brush with a substantially vertically oriented rotation axis, a brush mechanism for guiding and transporting the washing brush on a course over and around the automotive vehicle to be washed, and a control mechanism including a reversing drive for the washing brush and for the control of the washing apparatus. To avoid damage of the washing brush, a sensing element connected to the control mechanism is provided which responds to a damaging catching of the washing brush during rotation and travel over its course and reverses the rotation direction of the washing brush by acting on the control mechanism. Any of various criteria, including decrease of rotational motion of the brush, changes in brush orientation and torque, and drive-motor current changes are used by the sensing element in determining when to respond, and thus to reverse at least temporarily the rotation direction of the washing brush.
