We chose a robot vacuum cleaner for a house with an area of slightly less than 100 sq. M. in which two dogs and a cat for cleaning wool, sand. We did not receive advice and recommendations from friends and acquaintances due to the lack of such devices. We stopped at this because of the power and wide rubber brushes. Until you regret the purchase. He perfectly drew the plan of the house and cleaning began to take him less time. Now coming home after work there is not a single hair and you can walk barefoot. Now we are thinking about a washing robot to work together.
