Complete disappointment. I will buy Tefal again, and I will change it every two years. But at least I can use it humanly. Some pros: It is very easy to control, the brush conveniently turns itself in the right direction. An autonomous battery is a useful thing, there is a chance that when it fails, it can be replaced with another one. Takes up little space and stands on its own. There are different nozzles. Easy to clean. Has some cons: Compared to Tefal, which had to be replaced due to endless breakdowns of the turbo brush (and now the battery is dead), this Samsung does not anything at all! I don't know why the manufacturer makes such things - they are simply useless, but they are not so cheap. Also, there is no brush light.
To complement my review, I have added some photos to illustrate the product.
