If you have V11-12, of course, there is no point in taking it. But if the older ones could, you will already feel the difference. Pros: Original vacuum cleaner. Works just as well, maybe even better than my old V10. Beautiful, a great addition to the household - economic and cleanliness-loving owners. =) Its cons: Structural weaknesses are not improved. IMHO, the mounts could be replaced with aluminum ones, this would add a little weight, but also strength. It is clear that everything must break in order to be ated again and again . capitalism.
