A cleaning mat according to the present invention is designed to be placed
on a floor and to clean the undersides of shoes, feet, and other objects.
The cleaning pad includes a base sheet, which is designed to rest on the
floor. The base sheet has an upper surface and lower surface with the
lower surface designed to contact the floor. Multiple removable and
disposable cleaning sheets are supported in a stacked configuration on the
upper surface of the base sheet. Each of the cleaning sheets includes an
upper bibulous layer having an upper face. The bibulous layer is designed
to absorb liquid from an object that contacts the upper face. Each
cleaning sheet also includes a lower moisture barrier layer that has an
upper face adjacent the bibulous layer. The barrier layer is operative to
prevent transport of liquid from the bibulous layer to other cleaning
sheets below the barrier layer. In some embodiments, an adhesive covers a
portion of the upper face of the upper bibulous layer and is designed to
grab and retain dirt and debris that comes into contact with the upper
face. A portion of the upper face remains non-occluded such that
absorbency is maintained. In other embodiments, a plurality of
perforations are provided through the upper bibulous layer to retain
debris. In yet other embodiments, the moisture barrier layer extends
beyond the edges of the bibulous layer to define a perimeter surrounding
the bibulous layer. The perimeter of each of the cleaning sheets may be
bonded together with adhesive so as to seal in unexposed bibulous layers.
