Pros & cons
Segway Navimow i215 LiDAR
- ✓Maps itself on defined-border lawns; PCWorld had it mowing after a joystick nudge and two updates
- ✓LiDAR positioning keeps working under trees and at night where the i2 AWD's RTK drops out
- ✓Motorized 2 to 4 in cut height, app-adjustable, unlike the i2 AWD's knob
- ✓About 160 minutes per charge and 59 dB, quiet enough for evening runs
- ✓EdgeSense rides one wheel onto flush borders to shrink the trimming strip
- ✗No cliff sensor: PCWorld's unit slipped off a narrow grass edge twice and needed rescuing
- ✗Rear-wheel drive stalls on side slopes, ruts and wet patches despite the 45% rating
- ✗About 4,570 sq ft per cycle, so a full 0.37 acre takes a day or two
- ✗Vertical fences and walls still need a string trimmer
Dreame A3 AWD
- ✓Cheapest AWD, no-RTK robot mower from a major brand at $1,599.99
- ✓80% slope rating embarrasses every rear-drive mower near this price
- ✓LiDAR plus stereo cameras map without an antenna and work under trees
- ✓Built-in 4G (3 years free), GPS tracking and AirTag slot for theft protection
- ✓3-year limited warranty
- ✗Single 7.9-inch disc makes it slow; 1,000 sq ft can need a recharge mid-job
- ✗Amazon owners report tall weeds read as obstacles and mapping needing several attempts
- ✗Dock tower can separate from its base; support response has been slow
- ✗Edge gap is under 1.9 inches, not the Pro's 1.2, so borders still need touch-up
