One thing, on the suction of a Dyson there is no doubt - really top. The noise of the device is often criticized and I could not agree after three years of use. All family members are annoyed when the vacuum cleaner is turned on, really an impertinence. The five-year warranty are super and were even necessary for a part units plug piece and rickety pipe (plastic). But overall really totally satisfied as the new models with the volume I can not judge.
