A good vacuum cleaner, but there are some software flaws. The basic silicone brush is no good, you need to immediately take it with the combined one. Got pros: 1. Good navigation, does not knock on the walls 2. Extremely powerful, easy and convenient to clean and maintain 3. With a combined brush - quiet. With its cons. 1. The basic silicone brush on the laminate makes a knocking (without exaggeration hellishly loud !) sound during maneuvers and turns of the robot, I had to immediately buy a combined brush for 2600, the robot works quietly with it. 2. Often stops near the curtains, for example, with a request to remove something invisible in front of him. 3. Often does not find the base and goes to park next to the bedside table. 4. Doesn't clean corners very well. 5. It is not clear why, but it does not stop in some corners of the room in principle.
