Abstract

A disposable liquid absorbing cleaning pad for a mop includes a layer of sponge material, a layer of flexible open cell foam material made from melamine resin fixedly attached to the layer of sponge material and attachment structure fixedly secured to the layer of sponge material for removably attaching the cleaning pad to the mop. In one embodiment of the invention the mop is a squeeze mop which includes a mounting plate and the attachment structure includes a backing plate which is fixedly mounted onto the layer of sponge material and a pair of wing screw assemblies which are removably and slidably mounted on the backing plate for removably attaching the cleaning pad to the mounting plate. In using the cleaning pad the layer of flexible open cell foam material made from melamine resin is the layer that contacts the surface to be cleaned. In another embodiment of the invention, the cleaning pad has attachment structure for mounting the pad onto a butterfly mop and in another embodiment of the invention, the cleaning pad has attachment structure for mounting the pad onto a roller mop.
