First, the three wheels that swivel 360 degrees it's great, I did not know, it's great practice.
The machine moves in all directions, you can push it sideways, make a real turn able place it is very manipulable, that's a real plus.
I also liked the small brush section which is articulated, it can adopt all angles to get dust in inaccessible nooks, whether at the end of the long cane or stick.
For the noise level, I would say that we are in the usual average, my previous was 75dBA, so not silent, but it is not Miele louder than that.
For cons, I have noticed that the rate of decrease was not significantly decrease the volume?
I also like well the interior compartment for storing accessories, this is not new, but my previous vacuums do not have. It's still easy to store and does not run after them. There is much of the long nozzle, small natural bristle brush, and brush off cushions.
For the rest, there are the traditional functions, telescopic rod, valve on the butt to decrease depression (very noisy), the reel of high-performance electric cable, it changes the faignants reels that end up not wrap anything.
The suction power is really good, the electronic control power with LEDs is nice.
Finally there is a good capacity dust bag with the usual price and a Hepa filter engine to nearly 50 !!!!
