Very noisy but very effective. A larger model would be ideal for carpet.

Very pleased with this purchase.
At the first use we are surprised by the noise (it seems to use a sander: D) and I expected to brush a bit larger but as soon as I started attacking the sofa (I a well hairy and very generous in letting dog everywhere) I thought "why not have bought it sooner!" A passage and track, plus a hair and a clean cloth while ...
After I tested on my carpet (black!) And so I had trouble at all with the brush cleanse original (DC36) despite several passages, both with the mini turbo brush, I've never had my as clean carpet.

By cons I will imagine much the same thing a little bigger to treat larger areas but at least I could use it also for the car.
