Pros & cons
STIHL iMOW 6 EVO
- ✓More than double the 5 EVO's runtime, so a half-acre lawn finishes in fewer trips to the dock
- ✓US high-cut deck goes to 4.0 inches, which most wire mowers cannot reach
- ✓Ultrasonic sensors slow it before contact instead of relying only on the bumper
- ✓Mobile network module included, so the app works without home Wi-Fi
- ✓Quiet at 61 dB sound power with a floating three-blade disc and systematic lanes
- ✗Boundary and guide wire must be installed, and dealer install is extra on top of $3,099.99
- ✗US rating is only about 0.6 acre, not the 0.74 acre the international sheet promises
- ✗Cannot cut below 2.4 inches, a problem for bermuda or zoysia kept short
- ✗STIHL USA no longer publishes an iMOW product page, so specs live on dealer listings
Husqvarna Automower 435X AWD
