The fit is adapted to the Vileda Steam. I use a reference for cam 20 square meters, bathroom and kitchen each have their own. Therefore, one needs a small supply of it. There are exactly the same, which are the device there. The first 60 ° washes have the references survived. They are actually again become completely white. Hope they sometimes survive the dryer, if I do not catch a sorting out before the dryer. I can not say anything yet about durability. So far, I'm fully satisfied with these references.
