摘要： The present invention relates generally to a surface cleaning squeegee assembly and more specifically to a squeegee assembly mounted on a scrubber-dryer floor cleaning machine. The squeegee assembly includes a front squeegee having a number of spaced channels along a lower edge covered by seal flaps, and a rear squeegee having no channels. The front and rear squeegees define a vacuum chamber between them. Air, dirty water and surfactant are vacuumed into the vacuum chamber through the front squeegee channels for ultimate disposal. When the scrubber-dryer surface cleaning machine traverses over an uneven surface, the seal flaps close the channels to limit or eliminate any vacuum loss to the vacuum chamber.
