My husband looked at me, how I have been happy with our floor polisher for three months and decided to give me a gift for the holidays - an i7 + robot vacuum cleaner. It costs (for me) incredibly expensive, but it's so cool even I probably don't clean. Firstly, he cleans himself, i. E. so he cleaned up, went for a ride, goes to the station, throws his garbage from the container into the dust collector and for charging! Secondly, it is very very quiet, at night or early in the morning I turn it on easily, you canโt hear it. Thirdly, we have a living room, in which there are always some crumbs, hair, wool, because there is a large TV set there and, of course, everyone eats or chews or lies there, and so I set up cleaning so that it is in the living room the robot cleaned more carefully than in other rooms. It's comfortable. Fourthly, does he navigate the apartment very well, so that he gets tangled in the curtains or chewed up the wire? Not really! What do you. So far, I managed to run it only 4 times, I hope that it will continue to please me only)))
