I was hesitant to try another robo-vac but my wife convinced me. See, I had an old school roomba... one of the early models. It was constantly breaking down, needing new parts or getting clogged. It had terrible course finding and no logic to remember or optimize anything, it would just bump into stuff until it found its way. It got stuck under the table and in the corners of rooms. Well you get the idea. This is not that. No, this has opened my eyes to how far things have come! Pairing with my phone to control, set schedules, and such. Or the learning and better navigation. I'm sold, this little guy will be around our home for a long time!
