US Patent 8402588 Multi-layer surface treatment pad for motorized device

A multi-layer surface treating pad is disclosed. It has an upper layer suitable to serve as one part of a hook/loop type fastener system, a bottom layer which comprises an abrasive or polishing material, and a cleaning or other surface treating formulation positioned between the upper and bottom layer in the form of a bump which is positioned mostly in a central region of the pad. The bump of the formulation causes the upper layer to bulge upwardly so as to provide a visual indication as to where one optimally should attach a motorized device thereto.
