Abstract

A mop includes a first section having a first side, a second section having a second side, and an embedded, semi-permeable layer disposed between the first and second sections to manage an amount of liquid flowing from the first side to the second side.

Claims (34)

1. A mop comprising:

a first section having a first exterior side engageable with a surface, the first section including a first outer layer and a first middle layer;

a second section on a reverse side of the mop and having a second exterior side engageable with the surface, the second section including a second outer layer and a second middle layer; and

an embedded semi-permeable mesh layer disposed between the first and second sections to limit permeability of liquid flowing from the first side to the second side;

wherein the first middle layer is disposed between the first outer layer and the semi-permeable layer,

wherein the second middle layer is disposed between the second outer layer and the semi-permeable layer, and

wherein each of the first middle layer and the second middle layer defines a reservoir configured to receive, retain, and discharge liquid received by the mop.

2. The mop of claim 1 , wherein the semi-permeable layer is at least 50% less liquid permeable than that of mop material immediately adjacent the semi-permeable layer.

3. The mop of claim 1 , wherein the semi-permeable layer is at least 70% less liquid permeable than that of mop material immediately adjacent the semi-permeable layer.

4. The mop of claim 1 , wherein one or both of the first and second outer layers forms a front edge, a back edge, and two side edges of the mop, and wherein the mop is fully seamed along the front edge, the back edge, and the two side edges.

5. The mop of claim 1 , wherein the first outer layer and the second outer layer are defined by a continuous layer of material that wraps around the first middle layer, the second middle layer, and the semi-permeable layer.

6. The mop of claim 1 , wherein the first outer layer and the second outer layer are formed of a low-friction material.

7. A mop comprising:

a plurality of layers including an embedded, semi-permeable mesh layer that limits liquid transfer from a first side of the mop having a first outer layer and a first middle layer to a second side of the mop having a second outer layer and a second middle layer for controlled wetting of sides of the mop, wherein the embedded semi-permeable layer is substantially non-absorbent;

wherein the first middle layer is disposed between the first outer layer and the semi-permeable layer,

wherein the second middle layer is disposed between the second outer layer and the semi-permeable layer, and

wherein each of the first middle layer and the second middle layer defines a reservoir configured to receive, retain, and discharge liquid received by the mop.

8. The mop of claim 7 , further including a taped border extending along a portion of the mop.

9. The mop of claim 8 , wherein the plurality of layers form a front edge, a back edge, and two side edges of the mop, and wherein the mop is fully seamed along the front edge, the back edge, and the two side edges.

10. The mop of claim 7 , wherein the semi-permeable layer is made of warp knit polyester 150/48 FY and polyester 75/36 FY.

11. The mop of claim 7 , wherein the first outer layer and the second outer layer are defined by a continuous layer of material that wraps around the first middle layer, the second middle layer, and the semi-permeable layer.

12. The mop of claim 7 , wherein the first outer layer and the second outer layer are formed of a low-friction material.

13. A floor tool comprising:

a handle;

a tool head coupled the handle, the tool head including an engagement panel disposed along a bottom of the tool head, the engagement panel including engagement members and movable between a first position and a second position;

a tool release mechanism operably coupled to the engagement panel to move the engagement panel between the first position and the second position; and

a mop releasably coupled to the tool head via the engagement members, the mop including an embedded semi-permeable mesh layer that divides the mop into two sections to limit an amount of liquid flowing from a first side of the mop having a first outer layer and a first middle layer to a second side of the mop having a second outer layer and a second middle layer;

wherein the first middle layer is disposed between the first outer layer and the semi-permeable layer,

wherein the second middle layer is disposed between the second outer layer and the semi-permeable layer, and

wherein each of the first middle layer and the second middle layer defines a reservoir configured to receive, retain, and discharge liquid received by the mop.

14. The floor tool of claim 13 , wherein the first side of the mop defines a top outer surface and the second side of the mop defines a bottom outer surface.

15. The floor tool of claim 13 , wherein the first side is formed of a first material and the second side is formed of a second, different material.

16. The floor tool of claim 13 , wherein one or both of the first and second outer layers forms a front edge, a back edge, and two side edges of the mop, and wherein the mop is fully seamed along the front edge, the back edge, and the two side edges.

17. The floor tool of claim 13 , wherein the first outer layer and the second outer layer are defined by a continuous layer of material that wraps around the first middle layer, the second middle layer, and the semi-permeable layer.
