Abstract: A fluid-driven system for cleaning unwanted material from at least one of a brush or roller. The system includes a fluid passage having an inlet for receiving fluid and an outlet for removing fluid from the system. The system also includes a rotator disposed in the fluid passage between the inlet and the outlet. The rotator is driven by the fluid flow and transforms the fluid flow traveling through the fluid passage into rotational movement. The fluid-driven system employs a holder to engage the brush or roller. The holder is connected to and rotated by the rotator such that the brush or roller is caused to rotate about a central axis.
