I have had it for 4 years. The most ergonomic device I have encountered. Every part of it is carefully made to create difficulties in cleaning.
The intensity adjustment, although it has an analog regulator, has only 4 levels (the intensity does not change until it reaches the next level).
The maximum level pulls the carpets and sticks to the floor, while the immediately next one is less powerful than necessary.
I have given it a name to curse it as it bangs on doors and chairs while I am vacuuming due to its poorly placed wheels and it flips over at the first opportunity.
If it cost 70€, it would be worth 4 stars. At 200€, it is too much for just 2 stars.

One star and that's it!
My foot has a problem, it turns with the slightest movement from the floor to the carpet and then I struggle to turn it back with incredible difficulty! The warranty period has expired and the company can't do anything about such an expensive product that has a manufacturing issue. I regret spending 200€.
It is a heavy vacuum cleaner.
On the positive side, its power and almost silent operation.

It does not have good absorbency on carpets, the dirt just moves around, you can tell that it does not clean. If you change the setting to the strongest, you cannot vacuum because it gets stuck on the carpet and does not move. The foot is very bulky, so it is dysfunctional in some areas. Yes, it is quiet, but what good is that if it does not clean.... I had a Siemens vacuum for 20 years and that's why I chose Siemens again, but it is a complete disappointment... it's a shame for the money I spent

Very good absorbency on carpets. It seems to be of high quality construction. The handle is very convenient. I got it with a discount of 169.
