Claims9
A wipe cover for floor cleaning, comprising:
- a wipe-material layer having pile threads that project from this layer in the direction of a surface to be cleaned;
- means for securing the wipe-material layer to a retainer, wherein the wipe material layer is sized to be essentially covered by the retainer so that when a retainer is provided, the retainer overlies most of the wipe-material layer enabling forces to be transmitted directly from the retainer to the wipe-material layer;
- at least a first layer and a second layer of non-woven fabric, forming a border projecting beyond the wipe-material layer, wherein the first layer of non-woven fabric faces the surface to be cleaned and has a recess into which the wipe-material layer is embedded;
- and
- a secure mechanical connection of the wipe-material layer to the first layer, the connection being disposed so as to be concealed between the first layer and the second layer of non-woven fabric.
