this is my first Dyson, I am very satisfied, it makes no more noise than with my old bag, but it sure is not silent ... it sucks very well. the only downside is that the system that we take in hand (brush + + flexible wrist) is a little heavy, you have to get used to. by cons, which is fabulous, is that everything comes apart and is of very good quality. This is very useful when children suck a little anything (tissue ...) and that this mouth is accessed without any bother. it is also very easy to empty the dust bin. I wait to see resistance to passing time.
