The catch

Plug in your numbers
Can either mower handle your yard?
This checks hard limits only. Personal preferences are left out of the math.
Sunseeker Elite X5
Works with your numbersIts rating covers 0.5 acre and 60% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Segway Navimow X430
Works with your numbersIts rating covers 1 acre and 84% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.

Spec by spec
Where they really differ
| Spec | Sunseeker Elite X5 | Segway Navimow X430 | In practice |
|---|---|---|---|
| Rated area | 0.5 acre | 1 acre | Treat this published coverage as a sizing limit under the stated conditions. It does not guarantee results in every layout. |
| Published slope | 60 percent | 84 percent | If your site, surface or working range lies outside the published limits, this alone can decide your shortlist. |
| Drive | All-wheel drive | Four-wheel drive | It names the hardware or mechanism that does the work. A label by itself does not prove faster or better results. |
