I bought the part, because I was just unhappy with several similar brush from the surrounding construction and accessories markets (the mounts torn partially off quickly, or the brush was too easy and therefore it was very difficult to suck the ground). This is a great success, the holder will keep well (although I'm always wary of plastic), the "edge brushes" are very handy when there is a small layer of algae collected in the corners and edges. The brush is also heavy enough that you can easily can thus suck the ground.
