If we start with cleaning conditions, we have three rooms and three cats. We have been using this device for two weeks now. Before that, we had no RP because there is nothing to compare with. Really high-quality cleaning in tandem of a vacuum cleaner and wet cleaning. It takes about 45 minutes for 40 squares of serviced area. Sometimes every 4 cleanings it ignores the children's room, I don't know what it is connected with, it seems that the door is open. After a week of cleaning stopped the water on a rag. After checking, the motor turned out to be working, but it didn’t work. On the net I found information about what happens and how to solve it. Problems with built-in tank filter. After 10 minutes of manipulation everything worked.
