The structure has a support structure to which the cleaning material has been applied. The aim of the invention is to provide an absorbent structure with greater potential for variation and variants in terms of its cleaning and absorbency properties and/or effects. To this end, the inventive absorbent structure has a pocket or bag-shaped cavity in which pieces or strips of highly absorbent materials are located.
