Editor's notes

Mass converted from 43.7 lb (X330/X350; X390 43.9 lb). battery_runtime is the X330 figure (lowest). Navigation 'slam' chosen because EFLS 3.0 is RTK + vSLAM + VIO. Max mowing speed 2.6 ft/s (X330) / 3.3 ft/s (X350/X390) — not recorded as max_speed since it is a mowing, not travel, speed. The i-series was not researched.
