Normal regular vacuuming with a cylinder vacuum is perfectly adequate to keep your natural flooring looking fresh and clean. For stains or marks that the vacuum wont remove then there are cleaning products designed especially for natural fibre and these should be used. Never use water on natural fibre products unless specified by the manufacture to do so. If you wish to give the product a full clean after years of use or after a spillage etc there are local cleaners in all areas that specialise in the dry extract cleaning methods of plant fibre flooring.
