Abstract
A plurality of brush support arms, each having a distal end unit brush attached thereto, stand by in juxtaposition in a standby position. The brush support arm having a desired brush attached thereto is selected from the plurality of brush support arms. Then, the selected brush support arm is connected at its proximal end to a distal end of a swing arm. The brush support arm engaged with the swing arm is swung with the swing arm about a pivotal point at a proximal end of the swing arm. As a result, the brush attached to the distal end of the selected brush support arm is moved between the standby position and the center of a substrate, to clean the substrate with this brush. Upon completion of this substrate cleaning, the brush support arm is returned to the standby position. A different brush support arm is selected in the standby position for use in a subsequent cleaning operation, and the substrate is cleaned with the brush connected to this different brush support arm.
