The catch
Sunseeker S4
Fewer yards qualify because of the wider route requirement and the named grass exclusions.
Side by side
Sunseeker S4 vs MOVA LiDAX Ultra 1000: MOVA fits narrower routes, whereas S4 needs an 80 cm passage
Quick verdict
MOVA LiDAX Ultra 1000 is the pick when a narrow passage or a taller grass setting is central to the purchase. S4 is the pick for a compatible quarter-acre lawn with wider routes, where its offer and mapping setup suit you. The S4’s 80 cm passage requirement is a hard limit you need to check.
Before you buy
Why, and what it costs you
MOVA suits a thirty-inch gate better
Thirty inches works out to 76.2 cm. S4 asks for 80 cm, so that is too narrow, while MOVA’s 60 cm specification is cleared. Before choosing the model with the bigger-looking feature set, measure the tightest usable opening, latch hardware and any turn included.
Where this comes from
Sunseeker S4: Minimum passage 80 cm. MOVA LiDAX Ultra 1000: Minimum passage 60 cm. 30 × 2.54 = 76.2 cm.
The catch
MOVA LiDAX Ultra 1000
Meeting the passage specification does not promise that every tight turn or raised gate threshold will be manageable.

In practice
Differences you will notice
MOVA suits a thirty-inch gate better
Thirty inches works out to 76.2 cm. S4 asks for 80 cm, so that is too narrow, while MOVA’s 60 cm specification is cleared. Before choosing the model with the bigger-looking feature set, measure the tightest usable opening, latch hardware and any turn included.
How we worked this out
Sunseeker S4: Minimum passage 80 cm. MOVA LiDAX Ultra 1000: Minimum passage 60 cm. 30 × 2.54 = 76.2 cm.
Matching area labels do not add up to the same usable yard
Each is a quarter-acre model. Should a narrow connector keep the S4 from reaching the back section, the headline acreage does not matter. Because MOVA needs a narrower passage, one machine may be able to handle both sections with no carrying.
How we worked this out
Sunseeker S4: 0.25-acre rating and 80 cm route requirement. MOVA LiDAX Ultra 1000: 0.25-acre rating and 60 cm route requirement.
Handle the final strip of grass as its own job
The S4’s own FAQ mentions an 11 cm margin at a hard edge, roughly 4.3 inches that another tool has to take care of. MOVA’s edge-reaching system gives you a reason to study the boundary design, yet no mower here should be expected to leave a fence line needing no trimming.
How we worked this out
Sunseeker S4: 11 cm / 2.54 = 4.33 inches, official FAQ. MOVA LiDAX Ultra 1000: Manufacturer describes edge-reaching cutting. No zero-gap guarantee applied.

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 S4 | MOVA LiDAX Ultra 1000 | In practice |
|---|---|---|---|
| Rated coverage | 0.25 acre | 0.25 acre | For a lawn over this rating, neither is the right size to step up to. |
| Minimum passage | 80 cm | 60 cm | The gate may decide this matchup before navigation features come into it. |
| Interior slope rating | 42 percent | 45 percent | A slim spec difference is no substitute for a wet-grass traction test. |
| Grass and edging | Named grass exclusions and an 11 cm hard-edge FAQ margin | 1.2 to 3.9-inch cut range with edge-reaching cutting | Height, turf type and the trimming left over each need their own check. |

With Sunseeker S4
