It has been working for more than a year, it cleans significantly better than the previous vacuum cleaner from the mass market. The process of emptying debris is far from ideal. My apartment is clean, the main problem is fine dust, this vacuum cleaner is suitable for such a task. At the time of purchase, it cost significantly less than now. Different pros: The quality of materials and workmanship, the filter. Filtration quality - during operation, all dust, including the smallest, remains inside, and does not fly out from the other end of the vacuum cleaner. Cons: Ignorance and incompetence. The biggest complaints about the flask. The flask is small, the suction power and the quality of filtration depend on the level of filling with dust. After each cleaning, you need to shake it out, otherwise the second cleaning will be done by the vacuum cleaner at half strength. Since it collects very fine dust, when the flask is shaken out, it scatters in different directions. The latch of the flask itself is flimsy, it feels like it is about to fall apart.
