We have two German Shepherd dogs and this thing actually keeps the house clean! We were worried about long dog hair getting stuck in the roller, but if you keep the filter clean then you never have an issue.
Pros: - Easy to clean device - Finds its way home easily - Cleans around objects amazingly - Picks up an amazing amount of dirt - Good app (other than the con below) - Can set it to random-ish pattern or up and back (can't use the later for carpets for some reason) Cons: - First setup with phone wasn't as easy as it should have been, but follow the instructions and should be fine. I actually had to setup a wifi hotspot on our phone to get it to connect at fist. - Just cleans until it runs out of battery
The cons can be worked around just fine as this vacuum is only $398 and sometimes on sale. This cleans better than our old Samsung by miles.
As we're so impressed with it, we're actually considering upgrading to the ECOVACS DEEBOT 900.
UPDATE: We did end up getting the 900, IMHO the 600 is better for the price. The 600 has a bigger bin and its roller handles the dog hair better.
