In general, this is the first experience with this technique, so there is nothing to compare with. But I'm really satisfied, 4 power modes, washes. The cat is at home, so the wool, the stuck tray on the paws, the scattered food was a problem. This robot is a lifesaver. I won’t say that everything is perfect the first time, but you can always repeat the cleaning. Kopeck piece cleans in 30-35 minutes. The only negative, after a couple of cleanings, all chipped. . . Plus, he tried to remove the tinsel, and got into a fight with the Christmas tree. Finally a good scratch. And it's not very bad.
