1. A surface cleaning pad configured to be coupled to a cleaning implement, said surface cleaning pad comprising:
- a pad body having a cleaning surface configured for contact with a surface to be cleaned and an opposed surface, said cleaning surface and said opposed surface together defining a thickness of said pad body, said pad body comprising width-wise sides;
superabsorbent polymer particles maintained within a zone of said pad body, wherein said zone of said pad body occupies said thickness of said pad body and an area that is contiguous yet less than an area of said cleaning surface of said pad body;
a barrier layer disposed on the opposed surface of the pad body and between the pad body and the cleaning implement, the barrier layer being folded around the width-wise sides of the pad body;
said pad body having a region adjacent said zone, said region being substantially devoid of superabsorbent polymer particles; and
dirt entrapment members disposed on the cleaning surface of the pad body, the dirt entrapment members being folded and adhered to the cleaning surface.

Abstract
A floor cleaning pad is provided having a pad body comprising a cleaning surface configured for contact with a floor to be cleaned and an opposed surface configured to be coupled to a floor cleaning implement. The cleaning surface and the opposed surface defining a thickness of the pad body and superabsorbent polymer particles maintained within a zone of the pad body, and the zone of the superabsorbent polymer particles occupying a portion of the thickness and an area less than an area of the cleaning surface.
