Abstract

An apparatus for producing stress on a surface, comprising one or more service assembly and one or more cleaning assembly. The service assembly comprises one or more means for applying dirt to said surface, or one or more means for scuffing said surface, or one or more means for dragging a test material across said surface, or a combination thereof. The cleaning assembly comprises one or more scrubber, or one or more burnisher, or a combination thereof.

Also provided is a method of testing a surface with such an apparatus.

Claims

1. An apparatus for producing stress on a surface, said apparatus comprising one or more service assembly and one or more cleaning assembly,

(a) wherein said service assembly comprises one or more means for applying dirt to said surface, or one or more means for scuffing said surface, or a combination thereof, and

(b) wherein said cleaning assembly comprises one or more burnisher.

2. The apparatus of claim 1, further comprising one or more means for measuring the quality of said surface.

3. The apparatus of claim 1, wherein said service assembly comprises one or more means for applying dirt to said surface and one or more means for scuffing said surface.

4. The apparatus of claim 1, wherein said cleaning assembly additionally comprises one or more scrubber.

5. The apparatus of claim 1, wherein said surface is flooring material.

6. The apparatus of claim 1, wherein said surface comprises a coating on vinyl, linoleum, or other resilient material.

7. The apparatus of claim 1, further comprising means for independently controlling the exposure of said surface to said service assembly and the exposure of said surface to said cleaning assembly.

8. A method of testing a surface with the apparatus of claim 1 comprising the steps of

(i) one or more times, using said service assembly to apply dirt to said surface, or to scuff said surface, or a combination thereof, and

(ii) one or more times, using said cleaning assembly to burnish said surface.

9. The method of claim 8 comprising the steps of

(i) one or more times, using said service assembly to apply dirt to said surface and to scuff said surface, and

(ii) one or more times, using said cleaning assembly to burnish said surface.

10. The method of claim 8, further comprising the step of measuring the quality of said surface before said steps (a) and (b) and the step measuring the quality of said surface after said steps (a) and (b).

11. An apparatus for producing stress on a surface, said apparatus comprising one or more service assembly and one or more cleaning assembly,

(a) wherein said service assembly comprises one or more means for scuffing said surface, and

(b) wherein said cleaning assembly comprises one or more scrubber, or one or more burnisher, or a combination thereof;

wherein said service assembly comprises one or more means for scuffing said surface, wherein said means for scuffing said surface comprises means for bringing an object made of rubber into contact with said surface.

12. The apparatus of claim 11, further comprising one or more means for measuring the quality of said surface.

13. The apparatus of claim 11, wherein said service assembly additionally comprises one or more means for applying dirt to said surface.

14. The apparatus of claim 11, wherein said cleaning assembly comprises one or more scrubber and one or more burnisher.

15. The apparatus of claim 11, wherein said surface is flooring material.

16. The apparatus of claim 11, wherein said surface comprises a coating on vinyl, linoleum, or other resilient material.

17. The apparatus of claim 11, further comprising means for independently controlling the exposure of said surface to said service assembly and the exposure of said surface to said cleaning assembly.

18. A method of testing a surface with the apparatus of claim 11 comprising the steps of

(i) one or more times, using said service assembly to apply dirt to said surface, or to scuff said surface, or a combination thereof, and

(ii) one or more times, using said cleaning assembly to burnish said surface.

19. The method of claim 18 comprising the steps of

(i) one or more times, using said service assembly to apply dirt to said surface and to scuff said surface, and

(ii) one or more times, using said cleaning assembly to scrub said surface and to burnish said surface.

20. The method of claim 18, further comprising the step of measuring the quality of said surface before said steps (a) and (b) and the step measuring the quality of said surface after said steps (a) and (b).
