For 30-centimetre mop covers with hook-and-loop fastener: Thanks to its 360° rotating joint, the hook-and-loop holder with block system and cloth clips is ideally suited to professional high-performance cleaning of vertical and horizontal surfaces. Compared to cleaning tasks with cloths, the combination of holder and mop cover provides a significantly larger contact face and therefore significantly increased productivity. The Kärcher hook-and-loop holder is compatible with all handles with a hole diameter between 18 mm and 23 mm.
