I got this nozzle together with a vacuum cleaner AEG. In less than 2 years, the nozzle was just what the garbage. To find the error, took a while. Zuerts I doubted my vacuum cleaner and I thought, the suction power would no longer work. But eventually I understood that the nozzle was the problem. The front small wheels adjacent to the suction surface are made of soft material and to wear out. Eventually these wheels are then too small to still ensure the necessary distance to the ground. The nozzle then sucks itself firmly on the ground and scrapes along the ground. If I had floor tiles instead had, I would have scratched with the nozzle my floor. On the other hand, tiles she has "only" be adhered and could be pushed only with great effort on the tiles. So though it no longer works with the dust removal. So every 1.5 years in the model then probably a new nozzle due because the wheels can not be exchanged. So the complete nozzle has to go, because two of worn wheels. Unacceptable.
