I had always the Miele bust SUB 10 with no joints in use and was completely satisfied. But at some point, every brush close times, and because the simple joint loose brush was not in stock, I have, the SUB indulged the price higher part with 20 joints. I thought I have thus acquired something better. Not even close. Since this does not notice the joints of the brush and thus twists with every move himself to the side the part is almost completely useless. Since the best Miele quality will not help if the part of of house is already so not suitable for practical use. In addition, it is much higher than the SUB 10, resulting in that it is not so versatile. I have bought back after a few days the simpler, non-adjustable, but stable Miele brush SUB 10.
