ABSTRACT:
The specification discloses a floor scrubber wherein the squeegee is connected to the machine by a coil spring. The squeegee is free of direct rigid connection to the machine such that it can shift readily from side to side through the action of the spring. The squeegee is biased to a raised position by a second spring and can be forced downwardly into engagement with the floor through a unique pneumatic cylinder.
