Compared to corded vacuum cleaners, it is much more convenient, but the suction quality is mediocre. It seems to work, but for example, to process difficult places (for example, to "vacuum" a computer) - such a thing. But these are nuances. Generally satisfied. Got pros: Convenient because it's compact. I took it off the charger, pressed the button, that's it. Cons: The battery is not for "thoughtful" work. Dvushka 42 sq. M. If it's fast back and forth, then it's fine. If slowly, with a change of nozzles, with suddenly emerging ideas - "Maybe vacuum here too?" - does not channel, the battery sits down.
