Abstract:
1. A scrubber box, comprising: a tank adapted to receive a substrate for cleaning; a first support outside of the tank and adapted to couple to ends of a first scrubber brush disposed within the tank; a first motor mounted to the first support and adapted to rotate the first scrubber brush; a second support outside of the tank and adapted to couple to ends of a second scrubber brush; a second motor mounted to the second support and adapted to rotate the second scrubber brush; a base to which the first and second supports are pivotally mounted via spherical bearings adapted to permit toe-in of the first and second scrubber brushes; a brush gap actuator adapted, via a crank and rocker mechanism, to substantially simultaneously pivot the first and second supports toward or away from each other so as to permit the first and second scrubber brushes to substantially simultaneously achieve or break contact with the substrate; and a toe-in actuator adapted to move two of the spherical bearings toward or away from each other so as to adjust a toe-in angle between the first and second scrubber brushes.
