**UPDATE 2/3** I have decided to change my rating to 1 star and will be returning the item today due to an inaccurate description. According to the description and reviews, it should be quiet and crash-proof, which is not true. He is very loud and bumps into everything. I replaced my old Deebot with this. Compared to Deebot, the quality of the material seems pretty cheap. I like that the dust box is bigger than the Deebot. The reason I give it 4 stars is because it hurts me to set it up on my phone. The QR code was sent to a dead link and then the manual said the app was called "Smart Life". Well, after downloading a bunch of different apps that I thought might be it and they were all wrong, I decided to search for "Pureatic" and voila. It would be nice if the seller updated their manual with the correct instructions! Also, you need to make sure your home WiFi is ONLY connected to 2.4GHz. Mine was connected to both 2.4 and 5GHz so I had to go to my gateway admin tool and temporarily disable 5GHz for it to finally connect. Now that I've finally got everything set up, hopefully it lives up to the rest of the great reviews it's gotten here.
