The catch
ANTHBOT M5 LiDAR
Within a brief available window, the short cycle leaves less usable mowing time.
Side by side
ANTHBOT M5 LiDAR vs Sunseeker S4: S4 adds area and runtime only on lawns that meet its grass restrictions
Quick verdict
The S4 is the one to pick if its grass restrictions suit your lawn and you want a bigger lawn allowance or a longer stated run before it charges. The M5 LiDAR fits a much smaller lawn, provided its documented cutting range suits the grass and the offer looks good. Neither becomes right for every turf type just because of LiDAR.
Before you buy
Why, and what it costs you
A dry gap ahead of the children’s return gives the cycle difference some value
Say a suitable 90-minute mowing window opens between wet weather and afternoon lawn use. Starting full, M5 LiDAR runs for a claimed 40-minute stretch and then charges for the remainder. S4’s stated 90-minute run could fill the whole slot. Neither is proven to complete the lawn, and mowing has to wait for suitable conditions.
Where this comes from
ANTHBOT M5 LiDAR: 40-minute mowing and 60-minute charging claims. Sunseeker S4: 90-minute mowing and 80-minute charging claims. Illustrative full-charge start, no wet-weather capability inferred.
The catch
Sunseeker S4
A shaded yard that would otherwise suit it can be ruled out by its named grass exclusions.
ANTHBOT M5 LiDAR
- Why pick it
- The grass area stays under 500 m²
- A 30 to 70 mm cutting range works for your grass
- The catch
- Within a brief available window, the short cycle leaves less usable mowing time.
Sunseeker S4
- Why pick it
- You have more than one-eighth acre of grass, but less than a quarter acre
- Longer stretches of mowing without a break matter to you
- The catch
- A shaded yard that would otherwise suit it can be ruled out by its named grass exclusions.

Keep mowing time apart from the time the lawn is in use. Obstacle detection does not guarantee safety.

In practice
Differences you will notice
A dry gap ahead of the children’s return gives the cycle difference some value
Say a suitable 90-minute mowing window opens between wet weather and afternoon lawn use. Starting full, M5 LiDAR runs for a claimed 40-minute stretch and then charges for the remainder. S4’s stated 90-minute run could fill the whole slot. Neither is proven to complete the lawn, and mowing has to wait for suitable conditions.
How we worked this out
ANTHBOT M5 LiDAR: 40-minute mowing and 60-minute charging claims. Sunseeker S4: 90-minute mowing and 80-minute charging claims. Illustrative full-charge start, no wet-weather capability inferred.
A wider strip is cut by the smaller tier
Compared with S4’s seven-inch deck, M5 LiDAR’s 20 cm deck is about 12 percent wider, but its area allowance and run are smaller. For a family aiming to keep the lawn free at set times, going by cutting width alone would mislead.
How we worked this out
ANTHBOT M5 LiDAR: 20 cm deck, 500 m² rating and 40-minute run. Sunseeker S4: 7 × 2.54 = 17.78 cm deck. 20 / 17.78 - 1 = 12.5 percent. Quarter-acre rating and 90-minute run.
Shade and grass type each need their own filter
Shade can make antenna-free navigation attractive, yet S4’s named Zoysia and St. Augustine exclusions still hold. That M5 LiDAR’s page lacks the same exclusion does not automatically approve it for those grasses. Check turf compatibility before letting the runtime comparison decide.
How we worked this out
ANTHBOT M5 LiDAR: LiDAR and dual vision. No approval for specific turf species inferred. Sunseeker S4: LiDAR and vision with explicit US grass exclusions.
Plug in your numbers
Can either mower handle your yard?
This checks hard limits only. Personal preferences are left out of the math.
ANTHBOT M5 LiDAR
Does not work with your numbersIts rating covers 0.125 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Sunseeker S4
Works with your numbersIts rating covers 0.25 acre and 42% 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.
Option A
ANTHBOT, M5 LiDAR
M5 LiDAR
This is the small M5 fitted with LiDAR in place of RTK. The antenna is no longer required, but the short stated mowing cycle and low cutting range stay as they were.
- Best for
- The grass area stays under 500 m²
Facts we checked
- Rated area: 500 m², about one-eighth acre
- Stated mowing and charging: 40 and 60 minutes
- Deck width: 20 cm
- Interior slope rating: 45 percent
Option B
Sunseeker, S4
S4
This quarter-acre LiDAR mower needs no RTK antenna, but it comes with significant grass-type and boundary restrictions you should check before choosing it.
- Best for
- You have more than one-eighth acre of grass, but less than a quarter acre
Facts we checked
- Rated area: Quarter acre
- Stated mowing and charging: 90 and 80 minutes
- Deck width: Seven inches, about 17.8 cm
- Interior slope rating: 42 percent
Spec by spec
Where they really differ
| Spec | ANTHBOT M5 LiDAR | Sunseeker S4 | In practice |
|---|---|---|---|
| Rated area | 500 m², about one-eighth acre | Quarter acre | You cannot stretch the smaller robot tier to cover the larger lawn. |
| Stated mowing and charging | 40 and 60 minutes | 90 and 80 minutes | With limited lawn access, the cycle difference counts. |
| Deck width | 20 cm | Seven inches, about 17.8 cm | A narrower cutting strip comes with the larger-capacity S4. |
| Interior slope rating | 45 percent | 42 percent | Nothing about the small gap shows better wet-grass traction. |
| Grass suitability | 30 to 70 mm height, exact turf compatibility still needs checking | US guidance excludes Zoysia and St. Augustine | One manufacturer’s turf approval should not be assumed to apply to the other. |
Trade-offs
What each pick costs you
With ANTHBOT M5 LiDAR
- A three-inch mowing target is out of reach with a 70 mm maximum cut.
With Sunseeker S4
- A 30-inch gate is too narrow for the 80 cm minimum passage.
Change of plan
When the answer changes
The grass area stays under 500 m²
Go with ANTHBOT M5 LiDAR. A 30 to 70 mm cutting range works for your grass
You have more than one-eighth acre of grass, but less than a quarter acre
Go with Sunseeker S4. Longer stretches of mowing without a break matter to you
