I have compared with other "simple" robot vacuum cleaners and after 1 week I am very satisfied with my purchase. The benefit was gyroscopic navigation, which allows the vacuum to use a zigzag pattern when cleaning - moving back and forth as it mows the lawn. Other brands in this price range use a random pattern - go straight, hit something, turn randomly and go straight again until you hit something else. I had a problem with the mobile application - the scheduled start time regularly changed and increased by 11 hours. I emailed support and they provided updated firmware within 2 days which seems to have fixed the issue. We have 2 yellow labs that we keep in the kitchen and common room with baby gates most of the day. Only in these two rooms does the robot have to sweep every morning at 4:30 a.m., and the floors here are the cleanest in years. It runs in standard mode for around 90 minutes before returning to the charger. It will completely sweep both rooms twice in one charge. The bin is full and needs to be emptied daily, but it's a lot easier than trying to keep up with vacuuming and sweeping (which we never did).
