US Patent:

46060928, Aug 19, 1986

Filed:

Jan 22, 1985

Appl. No.:

6/693642

Inventors:

John J. Henning - Palatine IL

International Classification:

A47L 1130

US Classification:

15322

Abstract:

The disclosed spray-vacuum tool has a partitioned housing with two adjacent open faces, and defines adjacent liquid and vacuum chambers each open to both open housing faces. A pair of squeegees project beyond the open housing faces from opposite housing sides paralleling the partition, and each squeegee is angled across a sharp angle corresponding to the corner angle. A pair of end guides also project beyond the open housing faces from the other interconnecting housing sides, and the squeegee ends are butted flush against the end guides. Each end guide has a flat edge to be fitted flush against one of the respective surfaces to be cleaned, and the squeegees then are flexed then against the surfaces to be cleaned. This communicates the chambers together in the region adjacent the surfaces to be cleaned, but isolates this region from the tool exterior. Nozzle means in the liquid chamber spray washing and/or rinsing liquid directly against the surfaces to be cleaned; and a source of vacuum is connected, via a hollow wand swiveled at one end to the housing, to the vacuum chamber operable to draw away the liquid spray and dirt kicked up by the spray.

Abstract:

A spray-vacuum tool is disclosed for cleaning hard nonabsorbent surfaces, of varying smoothness or roughness and of varying materials including composition or ceramic tile, cement block, or even glass. The tool has a housing defining an interior cavity, and a partition divides the cavity into adjacent liquid and vacuum chambers each open to an open housing face. A pair of squeegees project beyond the open housing face from opposite housing sides paralleling the partition; and a pair of end guides also project beyond the open housing face from the other interconnecting housing sides, but with somewhat less projection than the squeegees have. The end guides extend slightly beyond the squeegees and the ends of each squeegee extend substantially up against the end guides. The end guides have flat edges designed to ride on the surface to be cleaned; and the squeegees then also ride against the same surface, but are somewhat flexed. This housing-squeegee-end guide containment of the chambers is immediately adjacent the surface to be cleaned.
