D8

neato actually used lidar and had good product.  the only issue with neato is reliability and high price

I run 11 Neatos 90 minutes 5 days per week in our house while we swim in another part of the house. Been doing it for 10 years. Not always the same Neato's though they are very repairable and I've made many repairs on them through the years.

Neato was the first with lidar. It was D shaped so it got edges and the aggressive brush was full width. Unfortunately it was over engineered like they were building a rocket ship with all kinds of sensors to make sure everything was working perfectly and sometimes sensors went bad throwing an error stopping it from running when it was perfectly fine. Company was purchased by a German company that destroyed it and they went out of business 2.5 years ago but kept the cloud servers running until recently. They can still be used manually by pressing the start button. But lots of features are gone. We use 11 so they are all done while we are swimming. We are retired and don't want to listen to them running for 8 hours per day if we just ran 1 per house level.
