Now the negatives: The first such nozzle was the vacuum cleaner here. Then broke down after about 2 years. Property me in Amazon the same part purchased new in March 2012 (really a lot cheaper than at Miele directly). This broke down again in May 2013. Since then I have tried even to tinker I could do no more warranty claims. So reappointed new. Now (Oct 2014) it's broken again. Now have turned me on Miele and was a bit disappointed. You can send me a new charge (!). But if I ever get broken I'm supposed to think about to purchase something else to me. The defective part can I send (at their own expense) to the Miele look then times ...
But now the great thing: Fortunately, there are Amazon. Within 5 minutes everything was clarified. Call me now was a new sent (free of charge) and I can return my old (also for free).
The problem with the part is that the neck, in which the tube is inserted to (by wear of plastic) dissolves over time from the base.
I in almost 6 years now the 4th Saugfuß need only 3 out of 5 stars.
