It does a good job of cleaning, even in inaccessible areas. It took me 30 minutes to clean a 60-square-foot room the first time. For the second time in 15 minutes, I took it off. Cleaning up after map construction takes only a short amount of time overall, but can take up to three or four runs through extremely nasty regions before it's truly clean. Controlling it from a mobile device is a breeze. Daily and weekly schedules of content are available. The 0.4-liter dust bin is inadequate for such a compact vacuum. In tight spaces, the side brush does a great job of sweeping. About three kilograms is a lot of weight. Everything about my purchase met or beyond my expectations.
