Abstract
A squeegee for use with a mobile surface scrubber to collect used liquid on a surface after being cleaned by the scrubber. The scrubber includes a mobile frame, a cleaning solution dispensing system mounted on the frame for wetting the surface with liquid, and at least one scrub brush attached to the frame for scrubbing the surface when wetted with liquid. In addition, the scrubber includes a vacuum system connected to the frame for removing liquid from the surface. The squeegee includes an elongate squeegee blade of flexible material having a lower edge engageable with the surface to collect the liquid on the surface for removal by the vacuum system. The squeegee also includes a series of openings through the squeegee blade extending up from the lower edge at intervals along the blade. Each opening tapers 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.
