I was very skeptical about the suction power, but I had to be taught a better. The suction power at level 1 for hard floors more than adequate. With Level 2 and 3 of the Bosch Zooo accepts without problems on deep-seated dirt from carpets. The brush rotates only only on the last two stages, thus the vacuum cleaner in the first stage very quiet. The turbo brush can be easily rid of hair and dirt. I have a single charge 3 100m² sucked times. With the kit, you can convert the vacuum cleaner to a Ghostbusters sucker :) After the cape, this is still easy to use and therefore easy to work super.
The only downside is the closure of the dust collector, this is how I do not find very easy to use.
