SEBO’s duo Cleaning System brilliantly cleans carpets in large or small areas and it effectively removes all types of spots and stubborn stains from upholstery and carpets. This do-it-yourself system is highly effective, easy to use, saves time and money, and avoids the potential carpet damage caused by some wet cleaning methods. The advantages of using the duo dry-cleaning system are the elimination of dust mite allergens, no need to move furniture, no detergent residue, a built-in fiber protector that helps to prevent future stains and soiling, and the ability to use the carpet or upholstery within 60 minutes after cleaning is completed. We suggest you let the duo powder sit in the carpet overnight. The GAF allergy research center in Germany found that six months after a single cleaning with duo-P, seven out of ten carpets remained free of dust mite allergens.
