I was skeptical about the battery gadget at first because I had only ever used high-end wired dusters (electrolux, bork, samsung) before. But I needed something sleek and small for my new digs, so I started researching the latest offerings. At first, I looked into washing nozzle models like the Tefal, Philips, and LG, but the study found that they either wash floors mediocrely (except for the LG A9 +, but that's a different story) or wash well but vacuum poorly (washing models from Bissel), and have limited functionality (you cannot vacuum furniture, for example). I decided on this model since the salesperson demonstrated its effectiveness on the V8 on the store floor and I learned from the advisors that there is a separate fluffy nozzle for wiping the floors. Like parquet and laminate flooring. Therefore, you should wet clean much less often if you can remember to do it. The normal setting produces minimal noise while providing sufficient force (mainly due to the efficient nozzles), whereas the highest setting is reserved for exceptionally challenging situations (such as cleaning a doormat). Very clean air is expelled; I had no idea that my previous vacuums were spewing dust through their bags and foam rubber. He vacuumed a sofa from IKEA that was only six months old, and then sucked a handful of dust out of it. I gave the computer, keyboard, and cushioned chairs a thorough cleaning and they now look brand new. We're not quite there yet, but we're on our way to the car. Cost-wise, a 50 square meter flat is sufficient for a thorough cleaning (assuming we're talking about the standard once-weekly service). But you can't bank on a repeat performance. Of the flaws, I saw unusual stains on the plastic, probably casting problems; of course, this has no bearing on the functionality, but for that price, I want nothing but the best. Additionally, there is some relative backlash of the parts (pipes with a body and nozzles), although this has no effect on the task.
