New model from iRobot. We were waiting for the release, as soon as it appeared, we immediately bought it. By design, the robot is coolly made, it differs for the better from others. He's also a little lower, so it's easier for him to drop in under the sofa, for example. So it vacuums cleanly, controlled remotely via the app. Not stupid. At first, only when I was building a map, I drove as if chaotically, now it's ok.
