I advise you to buy! Its pros: Great robot vacuum cleaner. We buy a second one. Good for removing dust from carpets and other surfaces. Have used the floor cleaner many times. The vacuum cleaner justifies itself. Happy with the purchase. Its cons: There is no cleaning function in one room, i. E. if you want to clean only one room and not touch the others, you have to close the door, and if you have an open space between rooms, then barycode.
