Abstract:
A squeegee for use with a mobile surface scrubber to collect liquid on a surface after being cleaned by the scrubber, said scrubber comprising a mobile frame, a cleaning solution dispensing system mounted on the frame for wetting the surface with liquid, at least one scrub brush attached to the frame for scrubbing the surface when wetted with liquid, and a vacuum system connected to the frame for removing used liquid from the surface, said squeegee comprising:an elongate squeegee blade of flexible material having a lower edge engageable with said surface to collect liquid on the surface for removal by the vacuum system; anda series of openings through the squeegee blade extending up from its lower edge at intervals along the blade, each opening tapering when the lower edge engages the surface to provide a relatively wide gap at the lower edge of the blade thereby permitting liquid to pass readily therethrough, and a narrower gap at an upper end of the opening having substantially no width thereby limiting passage of ambient air through the opening.
