Replace the old rolls of your Floor Cleaner with the Karcher FC Microfibre Gray and clean your floor thoroughly. This set contains 2 microfibre rolls that loosen and absorb both wet and dry dirt. They do not leave any fluff behind. You use the rollers on all hard floors, including fragile surfaces such as parquet or stone. The rolls can be washed in the washing machine afterwards. This set of microfibre rolls can only be used in combination with the Karcher Floor Cleaner.
