Abstract
A squeegee assembly is allowed to float on the floor surface by first, second and third linkage arms having first ends pivotably mounted to the chassis and second ends pivotably mounted to a mount for the squeegee assembly and allowing movement in more than one plane. The squeegee assembly is maintained at a generally constant angle independent of the pivotable movement of the linkage arms, with the generally constant angle being variable by adjusting the length of the third linkage arm. First and second extension springs have first ends attached to the chassis and have second ends attached to the mount at differing spacing than the first ends to cause the squeegee assembly to center the squeegee assembly relative to the chassis. In the preferred form, the ends of the extension springs attached to the chassis are vertically below the ends of the extension springs attached to the mount of the squeegee assembly to bias the squeegee assembly towards the floor surface. A T-shaped bracket is provided having a head for abutting with the first and second linkage arms to limit the upward extent of pivotable movement of the squeegee assembly and having a leg centered between and for abuttin…
