In a 1 bedroom apartment last year about 750 square ft and after reading several reviews on many robot vacs, I decided on this one. I have had it for about a year and 3 months now and I will go through the good and the bad. The Good: 1. Powerful enough. 2. I did try the spot clean thing a few times and it did a good job. 3. Large wheels and it's cameras are shielded by the large plastic disc that says Neato 4. It also has this technique where it raises itself on one side when going over uneven surfaces to clean or to try and clean a tighter space. 5. Cleaning it is easy, dirt bin is decent size, the app was easy to use and it was nice to see a daily report of what was cleaned. The Bad: 1. Large wheels have polymer /rubbery covering on them and this has started shredding 2. Powerful = good motor = loudddd. 3. Tighter space cleaning wasn't remotely close to great. Stuck sometimes about 3-4 times a week and then some weeks never got stuck. My furniture configuration never changed. Weird. 4. Ability to find the charging base was faulty about 20% of times. 5. Rotating brushes that would get into corners would routinely come off. 6. Incorrect sensing of bin being full about 40-50% of the time. 7. Why not design the LCD screen to show entire error message instead of just code? 8. Error message with no code and no cleaning. This is where the botvac is at now. Spent quite a bit of time with tech support and tried their camera and sensor cleaning techniques. Nothing will help. And since I am at the 1 year 3 month mark, the warranty is over. Takes $50 to ship, I wouldn't be surprised at getting a bill of about half of what I paid for the vac. At > $600 or so, I am expecting the vac to last, to do it's thing and not complain half the time or get stuck and most importantly, not break down on me after 1.25 years of use. Ridiculous price to pay for vac that can't even clean a 1 bedroom apartment properly? Why the 2 stars? Issues far outweigh the good.
