The device justifies its money. It is convenient to use it, they began to vacuum three times more often. The fur from the cat has become really less, now it does not accumulate in the corners. I watched an old dyson with friends, the Chinese product is in no way inferior. I did not find any mention of Xaomi in the documentation :) Pros: The suction power is sufficient. Working time is enough for 1-2 rooms. Light weight. Good for catching flies. Different cons: Shake out exactly in a bucket, otherwise everything will be in the dust. Large balls of wool sometimes get stuck in the container.
