Abstract:
1. A substrate cleaning apparatus, comprising: a hand held hand roller including a roller cleaning member rotationally mounted in a handle and having a tacky peripheral contact surface, said tacky peripheral contact surface adapted to transfer foreign particles during cleaning of substrates; a roller cleaning substrate having opposed first and second surfaces, and wherein the first surface is coated with an adhesive adapted to transfer and retain said foreign particles from the surface of the roller for disposal, and the second surface is a smooth surface; a mounting pad including a layer of hardness lower than 100 Shore Hardness Scale A, said layer adapted to bond the second surface of the roller cleaning substrate to the mounting pad without the use of adhesives or mechanical clamping; and wherein the mounting pad has a smooth surface configured to be brought into contact with the second surface of the cleaning substrate, and where the cleaning substrate is held on the mounting pad only by surface energy between the second surface of the cleaning substrate in contact with the smooth surface of the mounting pad, the cleaning substrate and the mounting pad being adapted such that a substrate retaining force generated by the surface energy will be greater than the lifting or separating force of the hand roller applied to the adhesive coated side of the cleaning substrate.
