Abstract

A floor cleaning tool is disclosed. The floor cleaning tool comprises a mop head including a perimeter, a working surface and back surface, opposite the working surface. The working surface includes a contact surface and a recessed surface. The contact surface is on a portion of the working surface for making contact with the surface to be cleaned. The contact surface includes a first capturing edge and a second capturing edge. The recessed surface is on a portion of the working surface and includes a first side surface recessed from the first capturing edge of the contact surface and a second side surface recessed from the second capturing edge of the contact surface. The entire contact surface is nonlinear.

First claim

What is claimed is:

1. A floor cleaning tool comprising:
a mop head including a working surface and back surface, opposite the working surface, and a perimeter forming at least a first branch, a second branch, and a third branch;
a contact surface on a portion of the working surface for making contact with the surface to be cleaned, wherein the contact surface includes a first capturing edge, a second capturing edge, and a third capturing edge;
a recessed surface on a portion of the working surface, the recessed surface includes a first side surface extending laterally from the first capturing edge and toward the back surface, a second side surface extending laterally from the second capturing edge and toward the back surface, and a third side surface extending laterally from the third capturing edge and toward the back surface;
wherein the contact surface includes at least a first extension in the first branch, a second extension in the second branch, and a third extension in the third branch, wherein the first, second and third extensions connect at a connection point within the working surface and wherein the first extension extends to a first point on the perimeter, the second extension extends to a second point on the perimeter, and the third extension extends to a third point on the perimeter, and further wherein the first-third extensions separate the first-third side surfaces from one another.

2. The cleaning tool of claim 1 , wherein the first capturing edge as a whole is continuous along a direction of an x-axis, which is perpendicular to an intended wiping direction.

3. The cleaning tool of claim 1 , further comprising a cleaning substrate placed over the working surface.

4. The cleaning tool of claim 1 , wherein the first side surface and second side surface are selected from the group consisting of straight sides, stepped sides, concave sides, and convex sides.

5. The cleaning tool of claim 1 , wherein the mop head is of a homogeneous material construction.

6. The cleaning tool of claim 1 , wherein the mop head is flexible material.

7. The cleaning tool of claim 1 , wherein the contact surface is symmetrical about a connection point.

8. The cleaning tool of claim 1 , wherein the contact surface is in a single plane.

9. The cleaning tool of claim 1 , wherein the first point, second point, and third point are equidistant from one another.

10. The floor cleaning tool of claim 1 , wherein the mop head further comprises planar side walls for cleaning adjacent a vertical surface.
