Abstract

A bi-directional squeegee jet wand for hard floor cleaning applications is disclosed, characterized by use of a pair of laterally spaced elongate vacuum ports, each of which carry a squeegee wiper blade upon its exterior portion which functions to accumulate spent cleaning solution in close proximity to a respective vacuum port during both forward and reverse manipulation of the wand upon the flow surface. A cleaning solution jet bar is positioned between the pair of vacuum ports such that the vacuum ports serve to deter splashing of the cleaning solution during dispensing which jet bar is advantageously removably mounted thereto permit use of the wand solely for solution extraction applications.

Claims

1. An improved cleaning wand for use in cleaning floors comprising:

a vacuum head having front and rear vacuum ports directed generally at right angles to said floor;

means disposed between said front and rear vacuum ports for spraying a cleaning solution upon a floor surface;

a handle cooperating with said vacuum head to manipulate said vacuum head in a forward and reverse direction upon the floor surface, said handle being further adapted to alternately tilt said vacuum head in said forward and said reverse directions as the operator manipulates said vacuum head in such directions; and

at least one squeegee blade positioned outside of and adjacent to at least one of said vacuum ports, each such squeegee blade being directed downwardly from said vacuum head and terminating at a point below said vacuum ports and said means for spraying cleaning solution such that when said vacuum head is in its operative position said squeegee blade(s) will be in direct contact with said floor, with said vacuum ports and said means for spraying cleaning solution being held above said floor, said squeegee blade(s) being further adapted to assume an angular configuration of approximately ninety degrees thereby blocking said adjacent vacuum port upon movement of said vacuum head in the direction of each such squeegee blade.

2. The cleaning wand of claim 1 wherein said pair of vacuum ports are positioned relative said cleaning solution dispensing means to provide a physical barrier to prevent splashing of cleaning solution outwardly from said vacuum head.

3. The cleaning wand of claim 2 wherein said cleaning solution dispensing means comprises a reservoir having at least one nozzle for directing cleaning solution upon the floor surface.

4. The cleaning wand of claim 3 wherein said reservoir includes plural nozzles for directing cleaning solution upon the floor surface.

5. The cleaning wand of claim 3 wherein said handle comprises an elongate tubular member the interior of which is in flow communication with said pair of vacuum ports.

6. The cleaning wand of claim 5 further comprising a pair of splash guards mountable to said vacuum head and sized to span the lateral spacing distance between said pair of vacuum ports.

7. The cleaning wand of claim 6 wherein said pair of splash guards are removably mounted to said vacuum head.

8. A method of cleaning a floor by use of a squeegee jet wand comprising the steps of:

dispensing a cleaning solution upon a floor surface between a pair of laterally spaced vacuum ports directed perpendicularly to said floor surface;

directing the cleaning solution upon the floor adjacent one of said pair of vacuum ports during movement of said pair of vacuum ports in a first direction upon the floor;

directing the cleaning solution upon the floor adjacent the other one of said pair of vacuum ports during movement of said pair of vacuum ports in a second direction generally opposite to said first direction;

supplying a vacuum to said vacuum ports to extract said cleaning solution from said floor;

providing one or more squeegee blades extending downwardly adjacent each of said vacuum port, said squeegee blades being adapted to alternately bend in approximate 90-degree angles when said wand is alternately moved and slightly tilted in said first and second direction, said alternate 90-degree bending of said squeegee blades being effective to cause each said squeegee blade to periodically cover and effect blockage of at least one of said perpendicularly directed vacuum ports; and

applying alternate movement and tilting of said wand in said first and second directions, thereby causing coincidental bending of said squeegee blades in alternating synchrony with said movement and tilting of said wand.
