Abstract: The molded body that has dimensions of length-breadth-height of 1 mm to 10 cm, comprises an open-cell synthetic organic foam material having a density of 5-500 kg/m 3>and an average pore diameter of 1 mu m to 1 mm, and two different zones having different chemical compositions. The molded body is modified on its surface in one zone with a cationic organic polymer and other zone with an anionic polymer, and has honeycomb-, cylindrical-, circular- or cuboid structure. The zones comprise two different open-cell foam materials. Independent claims are included for: (1) a method for cleaning surfaces using a vacuum cleaner; and (2) a method for producing a molded body.
