ABSTRACT OF THE DISCLOSURE Apparatus for maintaining surfaces that includes a powered mobile machine having a frame, a scrubbing tool, a liquid distributor ahead of the scrubbing tool, a clean solution tank for supplying liquid to the liquid distributor, a housing mounting the tool, a rear squeegee assembly and side squeegee assemblies, a dirty solution tank on the frame, and a vacuumized system for withdrawing liquid collected by the rear squeegee assembly and transferring it to the dirty solution tank. The rear squeegee assembly is preferably parabolic in plan view. Scissor type linkages are connected to the housing or other parts of the machine and each of the rear and side squeegee assemblies and are spring urged to urge the respective assembly downwardly with nearly constant pressure. Further, in each of the first and second embodiments of the rear squeegee assembly, parallel linkages mount the rear squeegee assembly for limited vertical movement relative the housing. Additionally, each of the squeegee assemblies, other than the one for the front squeegee of the third embodiment, includes quick release mechanism for removably retaining the squeegee on the respective squeegee frame, the quick release mechanism including an arcuately curved band for applying a squeegee clamping pressure. For the front squeegee of the third embodiment there is provided release mechanism that includes such a band and locking mechanism for releasably retaining the band in a clamping position that requires the turning of only a single bolt for releasing the clamping pressure applied by the band.
