<p>A foam core cleaning element of stitch-bonded construction having a multi-surface operative cleaning face. The cleaning element includes at least one fluid absorbing layer of absorptive polymeric foam. At least a first plurality of yarns extends in discontinuous patterned stitched relation through discrete selected zones of the fluid absorbing layer such that the first plurality of yarns forms a patterned array of first surface loop zones projecting outwardly away from a first side of the fluid absorbing layer in a defined patterned arrangement across the operative cleaning face of the cleaning element. A plurality of stitch-free zones of the polymeric foam define outwardly projecting convex curved surfaces at positions adjacent to the first surface loop zones across the operative cleaning face of the cleaning element.</p>
