Patent ID: 7607192

Claim:
A cleaning implement suitable for cleaning hard surfaces with a removably attachable sheet, comprising a handle connected to a mop head which is at least partially deformable, said mop head having a leading edge connected to a trailing edge by two side edges, characterized in that said mop head comprises a cleaning surface in the x-y plane and a z direction orthogonal thereto, said cleaning surface having a first cavity not extending to either side edge of said head, said first cavity extending from the leading edge towards the trailing edge, said first cavity forming an opening only adjacent the leading edge when said mop head is in contact with a hard surface to be cleaned, said opening having a width of between at least 50% and less than 100% of the entire length of the leading edge, wherein said first cavity has a shape in the x-y plane, which cavity converges towards the center of said mop head, and further has a taper which decreases in the z-direction, from the leading edge towards the trailing edge of said mop head.
