Pros & cons
Kress Mission RTKn KR173
- ✓Cheapest Kress with OAS obstacle avoidance, so it steers around objects rather than bumping them
- ✓No antenna, base station or wire; dealer install and app boundary
- ✓Parallel stripes with dead-reckoning fallback under trees and beside the house
- ✓1.2 acre maximum on a 72-hour cycle gives headroom over the 0.7 acre recommendation
- ✓Quiet 59 dB, 27.6 lb, electric height adjustment and a floating deck against scalping
- ✗Only works where a Kress dealer antenna covers your address; no coverage, no mower
- ✗Runtime, charge time, OAS sensor type and warranty term are not published on the US page
- ✗Same 7.9 in deck and 4 Ah pack as the cheaper KR172, so coverage growth comes from longer cycles, not more mower
Segway Navimow H1500N
- ✓Quietest Navimow at 54 dB thanks to in-wheel hub motors
- ✓About four hours of mowing per charge covers the rated area in one or two runs
- ✓Built-in 4G with GPS tracking and geofence alerts, one year included
- ✓Rain sensor plus IP66 body; owners say it handles ditches and rough ground
- ✓4-year warranty is the longest Segway offers
- ✗1.2-2.4 in cutting height is too low for most cool-season and St. Augustine lawns
- ✗RTK-only positioning; owners report drift of several feet and boundary overruns under trees
- ✗Four-hour recharge is slow by 2026 standards
- ✗Discontinued in favor of the H2 series; pricing and stock are erratic
- ✗Owners describe email-only support with multi-day response times
