... Again and again. is universal, ie, suitable for all vacuum cleaner bars, and has change with brush or without. We have new tiles (R9, so dull) and carpeting, and I can easily with this nozzle suck everywhere, nothing scratches, chafe or damage the floor. In addition, the nozzle is designed so that the intake air is used optimally. (Previously had one where the brush was very long, thus a lot of suction!) So: at any time, especially for the few bucks!
