Pros & cons
Segway Navimow X315
- ✓Same chassis, cameras and cut quality as the flagship X390 for less than half the price
- ✓RTK fused with visual SLAM keeps working under tree canopy
- ✓Fast recharge: about 30 minutes gives roughly 90 minutes of mowing
- ✓200+ object recognition with night vision makes after-dark runs practical
- ✓Cut height goes to 4 inches, unlike the older H series
- ✗Two-wheel drive; the 50% slope rating does not hold on side-hill runs
- ✗No physical rain sensor, only weather-forecast pausing
- ✗Leaves a few inches uncut along walls unless you add the Trimmer accessory
- ✗Only one year of 4G included versus two to five on the bigger X3 models
- ✗Pulled from Segway's own store; retailer stock only
Mammotion Luba 2 AWD X
- ✓Widest deck in the class at 15.7 inches, so a 3/4 acre lot finishes in a couple of sessions
- ✓True four-wheel drive with omni wheels holds 80 percent slopes and wet grass without spinning out
- ✓Now heavily discounted at Home Depot and Best Buy as Mammotion moves to the Luba 3
- ✓UltraSense AI camera keeps it inside the boundary when RTK drops under trees
- ✓Built-in 4G with a year of service, GPS tracking and a 3-year warranty
- ✗Requires a mounted RTK reference station with clear sky; bad placement causes most of the Float-signal and lost-position complaints
- ✗Being phased out, so firmware attention and accessory supply may fade
- ✗X trims top out at a 2.7 inch cut, too short for fescue or bluegrass lawns
- ✗At 40 pounds it is heavy to carry between separated lawns
