We have been very pleased even though he is a little louder and "different" sounds like "normal" vacuum cleaner. (There are well known people in the production / development, the sauger rebuilt so that it sounds like a vacuum cleaner to listen to ...) but he has a whole lot of power and I find it easier to carry than the standard vacuum cleaner, the one for the same price gets offered every once in Supermakrt and co.
of 10 November 2014 and 24 March 2015, we have just 1 bag used in a 3 bedroom apartment and a baby that makes a lot of dirty crumbles, cookies, etc.
to clean a wet carpet or suck dry it has already hergehalten which would never grab the same price category from the supermarket (the main thing they sound good to ^^).
Next, I'm going to try a slightly clogged drain to clean but I'm already sure that he grabs it without problems!
