You can not expect the efficiency of the Big Brother from Dreamy, but he copes with his task of an assistant in maintaining order. Personally, it took me a while to get used to its use (to the question of the effect of a dog on a leash), but this is more my physical unpreparedness than the fault of the machine itself. In general, it makes a pleasant impression (it pleases the eye, both in design and in the reduction of the layer of dirt), and I will check it over time for wear resistance and hidden flood stones from use.
I decided to add some photos to help readers get a better sense of what I experienced.
