Pros & cons
Lymow One Plus
- ✓Tracks plus dual rotary blades handle 30-degree-plus hills, tall grass and leaves that stop most robots
- ✓About 3 hours of runtime and a 90-minute recharge on the 10A kit, so it can run three cycles a day
- ✓Up to 80 zones with per-zone height, pattern and edge passes; 3-year warranty on a young brand
- ✓PCWorld found the tracks leave no visible turf marks despite the 78 lb weight
- ✓Owners on Lymow's site praise fast support and steady firmware fixes, including cleaner charging contacts than the original One
- ✗Loud for a robot: roughly 62 dB in standard mode and 74 dB in turbo
- ✗RTK antenna must be mounted with a clear sky view and mapping takes 30-45 minutes
- ✗Not a precise edge cutter; Tom's Guide saw flattened tufts on very uneven patches
- ✗Owners report occasional random offline stops and lost-position events between firmware updates
- ✗78.5 lb machine is a two-person lift and the dock needs a roughly 10 x 5 ft clear area
Segway Navimow X4
- ✓84% slope rating with four hub motors and suspension; owners say it crosses soggy, uneven ground the X3 cannot
- ✓17 in cut with two 180 W motors finishes an acre in a day
- ✓0.75 to 4 in height range covers Bermuda and zoysia as well as fescue
- ✓Antenna-free Network RTK setup; auto mapping took a reviewer ten minutes
- ✓Independent front steering turns without pivot scuffing
- ✓EdgeSense mows within about 2 in of walls and fences
- ✗One reviewer's unit climbed a raised patio edge and scuffed it; no drop-off sensing
- ✗First pass looks choppy, and wet turf gets chewed by the aggressive tires
- ✗24 in body width and 64 lb make narrow gates and carrying between zones awkward
- ✗68 dB is the loudest Navimow
