What's good
- Highest slope rating on this page (84%) and the widest deck (17 in)
- Widest cutting-height range here, adjusted automatically
- 360° cameras plus visual-inertial odometry back up RTK where the sky view is poor
What's not
- The loudest and heaviest mower here: 68 dB(A) and nearly 64 lb
- RTK still needs satellite signal and, without Network RTK at your address, a local antenna
Our verdict
The big-yard RTK choice. Its numbers are the strongest on the page for slope and deck width, and the extra cameras and odometry are Navimow's answer to RTK's tree-cover problem. Compared with the A3 AWD Pro, the choice is mostly navigation: open acreage with sky view favors this one, a treed or walled lot favors the LiDAR Dreame.
Compare with the alternatives
- Dreame A3 AWD 1000: a sloped or tree-shaded quarter-acre yard where you want no wire and no antenna
- Segway Navimow i210 AWD: an open quarter-acre lawn with good sky view and network rtk coverage
- Dreame A3 AWD Pro 3500: a half- to seven-eighths-acre lawn with slopes, trees or a complicated layout
- Dreame A3 AWD Pro 5000: an acre-plus lawn where you want lidar navigation instead of rtk
