It's the first robot vacuum cleaner I've ever owned, and I'm happy with it because the controls are simple and the design is straightforward, and it finishes cleaning in 5 minutes. A model that is more sophisticated will call for more knowledge and attention, but everything presented here is unambiguous and straightforward. I would recommend that you clear the area of activity for him well in advance of the time when he starts working, especially if there is no one else in the house. There is a possibility that the robot will become entangled in the wires or become caught on a little obstruction. It glides easily in open areas and cleans corners and skirting boards without causing damage. I only do dry cleaning, and once a week I give the house a thorough wet cleaning.
