Abstract: A pendulum rocker brush for a vehicle wash system is provided including a rocker arm, a rotatable coupler, a motor assembly, and a rocker brush head. Both the rocker brush head and motor assembly can be suspended from the coupler, freely dangling therefrom under the force of gravity, in an unbiased manner. The rocker brush head can pivot relative to the rocker arm through a swing angle between 10 and 45 degrees relative to vertical. The rotatable coupler and rocker brush head can be disposed at a pivoting angle between 10 and 45 degrees relative to a conveyor direction which a vehicle follows. When the rocker brush head encounters an opposing force above a movement threshold from the vehicle, the rocker brush head and the motor assembly can swing outward to the swing angle and at the pivoting angle so the vehicle is not damaged.
