It’s not just mapping.
Also, I recall Neato was often purchased and cannibalized by researchers for its lidar.
This was all cutting edge 10+ years ago. Even today, the features it supported offline then is just matched at best today in 2025/2026.
Not exceeded; and often crippled when offline.
There is not that much more to it than lidar and 2D slam as far as the core technology. There are a lot more features yes but they are not nearly as valuable. I agree they are better, but that's for reason of execution and non-enshitiffication, not core tech.
