Main trade-off
Sunseeker S4
The wider route requirement and named grass exclusions reduce the usable installations.
Head-to-head
Choose MOVA LiDAX Ultra 1000 when a narrow passage or taller grass setting is central to the purchase. Choose S4 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 to check.
Before you choose
Thirty inches is 76.2 cm. That falls below S4’s 80 cm requirement but above MOVA’s 60 cm specification. Measure the narrowest usable opening, including latch hardware and any turn, before choosing the larger-looking feature set.
What this is based on
Sunseeker S4: Minimum passage 80 cm. MOVA LiDAX Ultra 1000: Minimum passage 60 cm. 30 × 2.54 = 76.2 cm.
Main trade-off
The wider route requirement and named grass exclusions reduce the usable installations.
Main trade-off
The passage specification does not guarantee every tight turn or raised gate threshold will work.


Sunseeker S4 vs MOVA LiDAX Ultra 1000 for a shaded small yard. Check gates, grass restrictions and edge work before choosing two similar LiDAR mowers.
Winner by situation
Only MOVA meets the straight-passage width threshold. Check turns separately.
Both fit the area and antenna-free requirement. Check turf restrictions.
S4 explicitly excludes it. Check MOVA’s exact turf guidance.
Boundary design still determines the grass left behind.
What matters in practice
Thirty inches is 76.2 cm. That falls below S4’s 80 cm requirement but above MOVA’s 60 cm specification. Measure the narrowest usable opening, including latch hardware and any turn, before choosing the larger-looking feature set.
Sunseeker S4: Minimum passage 80 cm. MOVA LiDAX Ultra 1000: Minimum passage 60 cm. 30 × 2.54 = 76.2 cm.
Both are quarter-acre models. If a narrow connector prevents S4 reaching the back section, the headline acreage is irrelevant. MOVA’s narrower passage requirement can let one machine serve both sections without carrying it.
Sunseeker S4: 0.25-acre rating and 80 cm route requirement. MOVA LiDAX Ultra 1000: 0.25-acre rating and 60 cm route requirement.
S4’s own FAQ describes an 11 cm margin at a hard edge. That is about 4.3 inches left for another tool. MOVA’s edge-reaching system is a reason to examine the boundary design, but no mower in this comparison should be promised a trim-free fence line.
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 result checks hard limits only. Preferences stay out of the calculation.
Rated for 0.25 acre and 42% interior grade, with wire-free setup. Your input is 0.25 acre and 20% grade.

The area check uses the published maximum without adding a reserve. Where a systematic mowing rating is shown, that pattern is required for the maximum area. Boundary slopes can have a lower limit than interior ground. Trees, gates and disconnected zones still need checking.

Sunseeker, S4
A quarter-acre LiDAR mower that avoids an RTK antenna, with important grass-type and boundary restrictions to check before choosing it.

MOVA, LiDAX Ultra 1000
A quarter-acre LiDAR and vision mower with no RTK mast, a high cut ceiling and a documented route through narrow passages.
Meaningful differences
| What changes | Sunseeker S4 | MOVA LiDAX Ultra 1000 | Why it matters |
|---|---|---|---|
| Rated coverage | 0.25 acre | 0.25 acre | Neither is the right size upgrade for a lawn above this rating. |
| Minimum passage | 80 cm | 60 cm | A gate can settle this comparison before navigation features do. |
| Interior slope rating | 42 percent | 45 percent | A small specification gap is not 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 remaining trim work are separate checks. |
What you give up
Recommendation switch
Choose Sunseeker S4. The lawn uses grass accepted by Sunseeker
Choose MOVA LiDAX Ultra 1000. The 1.2 to 3.9-inch cutting range fits your grass routine
