I use this twice a day each day. For the price this is so awesome. The features such as phone notifications is nice. It’s super easy to clean and feels like a good quality machine. It doesn’t have mapping which is fine, especially at $149. It does however have sensors on the front, sides and bottom. Using the sensors it will go around chair and table legs individually. I like it so much I will just follow it around for 5 minutes at a time.HAHA. Seriously though, it’s amazing. The only con I see is it seems like it takes awhile to find “Home” when the battery gets low. I would think it would follow a sensors location.
With that said, I’d buy another one from Anker.
