I bought this about a month ago. The vacuum itself does an acceptable job. Although a stick or upright vacuum does a little better job. My biggest complaint is the app. I can't open the app and start cleaning, 80% of the time the button to clean doesn't show up. I have to push clean on the robot. I also can't tell it to dock early for the same reason, no button to click. Last night it ran without me telling it to. It got wrapping paper stuck in it. I will keep it because I do like the robot but the app needs a ton of work
