CLAIMS:

1. A method of cleaning a surface wherein successive regions of the surface are each subjected to a succession of rubbing strokes and alternate ones of said strokes are abrasive strokes, the intervening strokes being relatively non-abrasive strokes.

2. A method according to Clai 1 wherein the surface is rubbed with a pad having at least one abrasive region and at least one relatively non-abrasive region and wherein said regions are moved alternately across each of said regions of the surface to be cleaned.

3. A pad suitable for use in rubbing a floor and having a working surface which bears on the floor when the pad is in use, wherein the working surface includes one or more relatively abrasive regions and one or more relatively non-abrasive regions.

4. A pad according to Claim 3 wherein the or each relatively abrasive region is or are spaced from the periphery of the pad.

5. A pad according to Claim 3 or Claim 4 having a single relatively non-abrasive region wherein the or each relatively abrasive region is surrounded by the non-abrasive region.

6. A pad according to any one of Claims 3 to 5 wherein the or at least one of the relatively abrasive regions of said working surface is presented by an insert disposed in an opening formed in a main body of the pad.

7. A pad according to any one of Claims 3 to 5 comprising a body which presents a part of the working surface and defines at least one opening extending into or through the body from the working surface and further comprising an insert in the opening or one of the openings.

8. A pad according to Claim 6 or Claim 7 wherein the insert is an interference fit in the opening and is freely removable from the opening.

9. A pad according to any one of Claims 3 to 8 wherein the area of the relatively abrasive region or the aggregate area of the relatively abrasive regions of the working surface is within the range 2.5% to 50% of the area of the relatively non-abrasive region.

10. A pad according to any one of Claims 3 to 9 wherein the or each relatively non-abrasive region of the working surface is presented by a body of fibrous material bonded by a latex binder into a coherent, resiliently flexible body.

11. A pad suitable for use in rubbing a floor and having a working surface which bears on the floor when the pad is in use, wherein the pad defines at least one opening extending into or through the pad from the working surface thereof.

12. A pad according to Claim 11 wherein the opening is spaced from a centre of the pad.

13. A pad according to Claim 11 or Claim 12 wherein the opening is spaced from a periphery of the pad.

14. A pad according to any one of Claims 11 to 13 wherein the area of the opening is within the range 2.5% to 10% of the area of the working surface.

15. A pad according to any one of Claims 11 to 13 which defines a plurality of openings and wherein the aggregate area of the openings is within the range 8% to 50% of the area of the working surface.

16. A pad according to any one of Claims 11 to 15 wherein said opening is substantially cylindrical.

17. A pad according to any one of Claims 11 to 15 wherein said opening is substantially rectangular.

18. A set of pads comprising a larger pad according to any one of Claims 11 to 17 and a plurality of smaller pads, each of a size to fit into the opening or a respective opening in the larger pad.

19. A floor-cleaning pad substantially as herein described with reference to and as shown in the accompanying drawing.

20. Any novel feature or combination of features disclosed herein or in the accompanying drawing.
