Abstract
A low-profile side squeegee assembly for surface maintenance vehicles, capable of cleaning under so-called 'toe kicks'. In contrast with typical suspensions that are mounted directly above the center of the squeegee assembly, and are therefore too tall to fit under toe kicks, a low-profile suspension attaches at the ends of a squeegee assembly, and uses torsion springs to provide a downward force on the squeegee assembly. In order to counteract any potential twisting effects that might result from suspending the squeegee from the ends rather than the center, the squeegee assembly is mounted at an angle.
