We just got it up and running, the 2.4gh "only" is problematic with mesh internet systems and routers with multiple signals. The app only runs on phones basically and it would be a big plus if it could be run on a laptop with a larger screen to work with the mapping.
That said so far it cleans well, finds its dock even though we could not have 3 feet clear on both sides of the dock. The vacuum and the self-empty dock look to be built well. Time will tell on longevity, but at this point we are very satisfied with its performance.
one star off on performance and design is for the app.
