I was very pleased with the purchase, however, for our apartment of 47 sq. M. I realized that it was possible to take a cheaper vacuum cleaner, because for 1 cleaning the robot spends only about 6% of the battery. With its pros. Intelligence, ease of cleaning, work with Alice and with the phone. Perfectly cleans, taken for parquet and against cat hair. We clean 2 times a day and 3 times wet cleaning a week. In general, we do not spare the vacuum cleaner and use it at 100%) It overcomes the threshold of a door measuring 5 cm in height, we were very surprised by this) Cons: Sometimes the sofa gets stuck on the legs, they are not perpendicular to the floor, but at an angle. He drives a wheel on them, but cannot get out :( But this happens a couple of times a week.
