Consider your setup
Maximum mowing area
- Segway Navimow X390108900 sq ft
- Segway Navimow X45065340 sq ft
Measure the actual lawn area, not the property size. Check whether slopes, separate zones and narrow passages impose additional limits.
Inspect the specificationsConsider your setup
Maximum slope
- Segway Navimow X39050%
- Segway Navimow X45084%
Check whether the slope limit applies inside the lawn or at its boundary. Percent gradient and degrees are different units.

Battery Life
- Segway Navimow X390240 minutes
- Segway Navimow X450110 minutes
Compare the stated test conditions. Catalog battery figures alone do not predict runtime in your home.
Inspect the specificationsYour priorities, side by side
Focus on what changes.
Mark the specifications you care about. Open manufacturer sources for verification scope; fields without citations remain catalog data. Expand notes for other qualifications.
