Abstract
A refill is designed for use with a mop of the type having a mop head with a lower surface and an opposed upper surface interconnected by a leading and a trailing edge. The mop head has a gripper device on its upper surface for retaining a cleaning sheet on the mop head. The refill includes a base layer with a front edge and an opposed rear edge, and a midportion between the front and rear edges. The base layer is designed to be wrapped about the mop head with the midportion adjacent to the lower surface of the mop head and the front and rear edges wrapping onto the upper surface of the mop head so as to be retained by the gripper. Multiple cleaning sheets are each removably supported on the midportion of the base layer in a stacked configuration. Each of the sheets has an outward face for cleaning and an opposed inward face. The outward face of each of the sheets is designed to contact a surface to be cleaned and to thereby become soiled. When the outward face of the outermost sheet becomes soiled, the sheet may be peeled away to expose a non-soiled sheet.
