- ✓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
