In general terms, of course, the idea is very good, the build quality and materials are at the highest level, but again, I repeat, this is a broom, not a vacuum cleaner, so do not part with an old trusted friend, because. this one cleans just on the surface. And it doesn't matter which model you buy, the cheapest one for 20t or for 50t, the effect is the same, it's checked. By the way, one charge at medium power is enough for 3-4 days of cleaning a standard kopeck piece.See full review
