There is no overall winner here — which mower is “best” depends on your garden. These are the categories where one model is measurably ahead on a published figure.
Segway Navimow X420
Smallest rated working area of the two — the least mower you need for a compact garden, with the least capacity going unused.
Where they differ
- Working area ranges from 2,000 m² to 2,500 m² — the single biggest practical difference between them.
- Slope ratings differ (45% (about 24°) to 84% (about 40°)), which matters if any part of your garden is on a bank.
- Cutting width ranges from 180 mm to 430 mm, which affects how long each mow takes.
What they have in common
- Both have a rain sensor.
- Both support multiple mowing zones.
- Neither needs a buried boundary wire.
