Patent ID: 6895633

Claim:
A squeegee assembly for removing solution from a floor surface with a surface maintenance vehicle, said squeegee assembly comprising: a squeegee frame member; a pair of deformable squeegee members coupled to the squeegee frame member which together define at least a portion of a vacuum chamber; and a clog reduction structure having an inlet in fluid communication with the vacuum chamber, an outlet in fluid communication with a vacuum conduit having a predetermined cross sectional area taken in a plane generally perpendicular to a direction of elongation, and a configured surface between said inlet and said outlet, wherein said inlet is generally circular and has a substantially larger cross sectional area than said outlet, and wherein the configured surface maintains a cross sectional area, taken in a plane generally perpendicular to the pair of squeegee members, which is equal to or greater than the predetermined cross sectional area of the vacuum conduit.
