Before this vacuum cleaner was wired. In principle, a good device, copes with its duties, but compared to a corded vacuum cleaner, it worse. I've never used wireless, so there's nothing to compare with, maybe I'm slandering in vain. In addition, along with the vacuum cleaner, they sent for free an electric corkscrew of the same company, costing ~ 2500. Also a good thing)) Special thanks for this
