To be honest, until I received it, after listening to my friend, I didn’t fully believe that robots really know how to clean thoroughly and are even able to replace my daily bending over. It’s good that I didn’t listen to anyone and decided to try. The vacuum cleaner cleans ten out of ten, leaving not a speck of dust behind. Even the fluffy fur of the cat is now gone, and my back does not hurt at the same time!))
