I can agree with the positive reviews only. With this nozzle, it is much more pleasant to suck as with the original nozzle of my admittedly rather lower than upper-class Simenes vacuum cleaner, which is now already 8 years old. Especially on unfixed, 'reefs leagues' carpets that could be sucking the old nozzle only in one direction, a clear difference can be felt - with this nozzle is such carpets can also crisscross suck. So a recommended product and significantly less expensive than original parts from Siemens and also the replacement jets, I have seen the relevant electric markets.
