It's just Miracle Technology, it copes with everything, there is no need to control the operation of the vacuum cleaner, I even got lazy with it) the vacuum cleaner does not get stuck in the corners, in general it quickly copes with hard-to-reach places, does not scratch a smooth surface - I checked it on parquet and tiles. For what I appreciate more - it perfectly cleans the deep pile of the carpet and collects wool and long hair, while all this does not get confused and does not get stuck in the brushes, everything goes into the bag by itself. It does not require special care, it makes moderate noise, the assembly is of high quality, so I'm sure it will last a long time.
