Anthbot M9 vs Gardena SILENO life
Quick take: The Anthbot M9 costs $16 less; the Anthbot M9 skips the boundary-wire install entirely while the Gardena SILENO life needs a perimeter wire laid but doesn't care about tree cover or satellite signal; the Anthbot M9 is rated for a larger lawn (10,764 sq ft); the Anthbot M9 is rated for steeper ground (45%); the Anthbot M9 cuts taller (up to 2.8"), which matters for fescue and warm-season grasses; the Anthbot M9 has built-in cellular for GPS tracking and away-from-home control.

Pros & cons
Anthbot M9
- ✓Two hands-on reviews found it fuss-free: clean U-pattern stripes and reliable obstacle avoidance
- ✓Quarter-acre coverage with 4G and a rain sensor for $699, undercutting the Navimow i110N by $230
- ✓Ten-minute setup and auto-mapping that handled about 90 percent of a test yard
- ✓Quiet enough at 58 dB that a reviewer could not tell it was running
- ✓Resumes where it stopped after a mid-job recharge
- ✓3-year warranty on mower and station
- ✗2.8 inch maximum cut height is short for cool-season lawns
- ✗Shadows can trigger false obstacle stops
- ✗Two-wheel drive; 45 percent is a straight-run rating, not a side-hill one
Gardena SILENO life
- ✓8.7 in deck cuts wider than the 6.3 in city and minimo and clears 8,100 sq ft on a 65-minute cycle
- ✓58 dB and mows in rain, so it can run on any schedule without bothering neighbors
- ✓Guide wire with CorridorCut makes narrow passages and outlying areas reliable
- ✓PIN plus alarm is a step up from the city and minimo
- ✓About $715 undercuts most wired mowers with this coverage
- ✗2.0 in maximum cut height is too short for cool-season grass
- ✗Bluetooth-only app: no remote start, stuck alerts or GPS tracking
- ✗Bumper-only obstacle handling unless you buy the add-on radar
- ✗Legacy model on Gardena's site; the 1000 size is no longer priced in the US
- ✗No edge-cutting mode, so trimming along walls is still on you
