ABSTRACT:
A snap-together wet nozzle for use with a vacuum assembly is described, as well as a removable squeegee assembly for use in combination with a wet nozzle for a vacuum assembly. The snap-together wet nozzle includes an elongated, generally U-shaped nozzle housing having outwardly tapering walls, spaced apart closed ends, and a connecting tube passageway for association with a vacuum-producing means, such as a wet/dry vacuum, and further includes a squeegee assembly capable of being insertably mounted within the elongated, generally U-shaped nozzle housing. The squeegee assembly generally includes a squeegee element comprising a plurality of openings extending through the squeegee element; a first, elongated squeegee bar having spaced apart end grooves at each of its ends; and a second, elongated squeegee bar having spaced apart locking end tabs at each of its ends and a plurality of vanes spaced across the interior face of the bar, wherein when the squeegee assembly is assembled and ready for insertion into the nozzle, the squeegee element is located intermediate between the first and second squeegee bars, and wherein the first and second squeegee bars interlock by the engagement of the end tabs of the second squeegee bar with the end grooves of the first squeegee bar.
