Abstract
A floor cleaning machine is provided with at least two movable squeegees to provide coverage of the liquid applied to the floor in a path with the squeegees extending beyond the outer perimeter sides of the liquid path both during straight ahead movement and during turning maneuvers. The squeegee assemblies are carried by a chassis. A floor scrubbing device is provided to apply liquid to the floor and to mix dirt on the floor with the applied liquid.
