Abstract

A molded component or boot is removably fitted to the narrow edges of a commercial carpet cleaning wand otherwise in contact with carpet to be cleaned. Wider bearing surfaces of the attachment or boot allow for smoother action of the carpet cleaning wand over the carpet, without skip or chatter due to directional nap, such as associated with short nap carpets (e.g., berbers or indoor/outdoor carpet). Functional life of the carpet cleaning wand is extended indefinitely through removal and replacement of the attachment. Screw mounting or other simple removable elements facilitate rapid field service. Lightweight molded plastic contributes to ergonomic aspects without impeding any “spray down” or vacuum functions of the wand.

Claims

1. A carpet cleaning system, comprising:

a base unit providing vacuum pressure and fluid handling;

a vacuum hose having a first end and a second end, wherein said first end is connected to said base unit;

a fluid supply hose having a first supply hose end and a second supply hose end, wherein said first supply hose end is connected to said base unit;

a rigid main body having a first main body end and a second main body end, wherein said first main body end is connected to said second end of said vacuum hose;

a wand head defining a fluid outlet and a vacuum inlet, said wand head connected to said second main body end and said second supply hose end, wherein said fluid outlet and vacuum inlet are defined by edge surfaces of said wand head including a central divider edge surface running the width of said wand head;

a wand head boot defining an interface surface for movement along a surface to be cleaned, said wand head boot connected to said wand head opposite said main body second end, said wand head boot defining a single vacuum inlet opening in fluid communication with said vacuum inlet of said wand head, wherein said wand head boot further comprises channels for receipt of said edge surfaces and said central divider edge surface when connected to said wand head.

2. A carpet cleaning system according to claim 1, wherein said base unit is mobile.

3. A carpet cleaning system according to claim 2, wherein said base unit further comprises rollers.

4. A carpet cleaning system according to claim 1, wherein said rigid main body further comprises a handle portion at the first main body end.

5. A carpet cleaning system according to claim 1, wherein said channels are L-shaped.

6. A carpet cleaning system according to claim 1, wherein said wand head boot further comprises a tab through which a securement opening is formed.

7. A carpet cleaning system according to claim 1, wherein said wand head boot is made of molded plastic.

8. A carpet cleaning system according to claim 7, wherein said wand head boot is made of molded black Acetal plastic.

9. A carpet cleaning system according to claim 1, wherein said interface surface comprises contact surfaces corresponding to each of said edge surfaces and said central divider edge surface and said first and second openings, said contact surfaces being broader than said edge surfaces and said central divider edge surface.

10. A carpet cleaning system as defined in claim 1, wherein said wand head boot defines a fluid outlet opening in fluid communication with said fluid outlet of said wand head.

11. A carpet cleaning system, comprising:

a mobile base unit providing vacuum pressure and fluid handling;

a vacuum hose having a first end and a second end, wherein said first end is connected to said mobile base unit;

a fluid supply hose having a first supply hose end and a second supply hose end, wherein said first supply hose end is connected to said mobile base unit;

a rigid main body having a first main body end and a second main body end, wherein said first main body end is connected to said second end of said vacuum hose;

a wand head connected to said second main body end and said second supply hose end, said wand head defining at least two pathways for transmission of a fluid cleaning material, wherein said wand head further comprises two spray nozzles and two feed hoses, said feed hoses being connected at one end to said second supply hose end through a splitter and being connected at an opposing end to said spray nozzles;

a wand head boot for connection to said wand head opposite said main body second end defining at least two openings, said openings corresponding to said at least two pathways when said wand head boot is connected to said wand head.

12. A carpet cleaning system according to claim 11, wherein said mobile base unit further comprises rollers.

13. A carpet cleaning system according to claim 11, wherein said mobile base unit is a truck-mounted base unit.

14. A carpet cleaning system according to claim 11, wherein said fluid supply hose is connected along its length to said vacuum hose and said main body.

15. A carpet cleaning system according to claim 14, wherein said fluid supply hose is internal to said vacuum hose and said main body.

16. A carpet cleaning system according to claim 11, wherein said rigid main body further comprises a handle portion at the first main body end.

17. A carpet cleaning system according to claim 16, wherein said handle portion is adjustable.

18. A carpet cleaning system according to claim 17, wherein said handle portion includes a trigger for initiating and terminating operation of said system.

19. A carpet cleaning system according to claim 11, wherein said spray nozzles transmit said fluid provided via said fluid supply hose through said splitter and said feed hoses to a surface to be cleaned.

20. A carpet cleaning system according to claim 11, wherein said at least two pathways include a fluid outlet in fluid communication with said nozzles and a vacuum inlet.

21. A carpet cleaning system as defined in claim 11, wherein said wand head boot further comprises a tab, said tab acting as a point of connection with said wand head.

22. A carpet cleaning system according to claim 11, wherein said wand head boot is made of molded plastic.

23. A carpet cleaning system, comprising:

a base unit providing vacuum pressure and fluid handling;

a vacuum hose having a first end and a second end, wherein said first end is connected to said base unit;

a fluid supply hose having a first supply hose end and a second supply hose end, wherein said first supply hose end is connected to said base unit;

a rigid main body having a first main body end and a second main body end, wherein said first main body end is connected to said second end of said vacuum hose;

a wand head defining a fluid outlet and a vacuum inlet, said wand head connected to said second main body end and said second supply hose end;

a wand head boot defining an interface surface for movement along a surface to be cleaned, said wand head boot connected to said wand head opposite said main body second end, wherein said wand head boot further comprises a tab, said tab acting as a point of connection with said wand head.

24. A carpet cleaning system according to claim 23, wherein said wand head boot defines a first opening in fluid communication with said fluid outlet and a second opening in fluid communication with said vacuum inlet of said wand head.

25. A carpet cleaning system according to claim 24, wherein said fluid outlet and vacuum inlet are defined by edge surfaces of said wand head including a central divider edge surface running the width of said wand head.
