I chose according to reviews and ratings from four different online resource stores, and taking into account all the pros and cons, I took this option. According to the recommendations and reviews, I immediately put on a nylon sock - it works. )) The floor brush is quite fidgety, but I considered this a plus, because in my opinion it gives maneuverability to cleaning. Dust and small debris begins to in from a distance of several centimeters, large crumbs are not always ed in immediately - you have to slightly raise the brush, since the distance between the floor and the brush is very small. We do not have carpets, so it is not possible to check the degree of work with them.
