Quick Verdict
If you want a budget LiDAR robot mower for a small shaded yard without RTK, the Anthbot M5 LiDAR is the cheaper option and is explicitly marketed for compact, enclosed gardens. The Sunseeker S4 costs more at MSRP, but it offers a larger maximum mapping area and a faster charging time, which may matter if your lawn is closer to its size limit.
For a homeowner comparing Sunseeker S4 vs Anthbot M5 LiDAR, the decision mostly comes down to yard size, budget, and whether you want the larger mapped area of the Sunseeker or the lower price of the Anthbot.

Sunseeker S4: Where It Fits
The Sunseeker S4 is the better fit if your yard is on the larger end of this comparison and you want a wire-free mower without RTK. Its manufacturer-listed maximum mapping area is 0.25 acre, or 10,890 ft², which gives it more headroom than the Anthbot M5 LiDAR’s 500m² rating. That makes the S4 easier to consider if your lawn is a small suburban lot rather than a compact courtyard.
It uses Vision AI plus 360° 3D LiDAR navigation, and Sunseeker says it does not need a buried perimeter wire. The mower is also rated for a 42% / 22° maximum slope, which is strong for a budget-friendly, no-RTK model. Another practical advantage is the charging time: 80 minutes, with 90 minutes of mowing time per charge. For homeowners who want a mower that can cover a modest lawn area without the hassle of perimeter wire installation, that combination is appealing.
There are a few important caveats. Sunseeker does not list cutting height on the product page, and it says the S4 is not compatible with Zoysia or St. Augustine grass. For buyers with either of those grass types, that is a major filter. The 7-inch cutting width is also straightforward rather than especially wide, so this is best viewed as a compact, wire-free mower for manageable lawns, not a high-output machine for bigger properties.
Anthbot M5 LiDAR: Where It Fits
The Anthbot M5 LiDAR is the more affordable option in this matchup, with an MSRP of $799.00. It is clearly aimed at compact, enclosed gardens, which makes it a strong candidate for homeowners with smaller spaces who want a robot mower no RTK small yard solution. Anthbot lists wire-free operation as “No Wire, No RTK,” so it avoids the installation burden of a buried perimeter wire.
Its navigation system combines 360° LiDAR with Dual Vision, and the mower is rated for a 45% / 24° maximum slope. That gives it a slightly steeper slope rating than the Sunseeker S4 on paper. Anthbot also lists a cutting height range of 3 to 7cm, adjusted in the app, which gives buyers a clearer sense of mowing range than the Sunseeker’s product page does.
The trade-off is capacity. Anthbot lists maximum area as up to 500m², which is substantially smaller than the Sunseeker S4’s maximum mapping area. Runtime and charging details are not listed by the manufacturer, so buyers who care about cycle length will have less to go on. In practical terms, the M5 LiDAR makes the most sense for a small, enclosed yard where price matters and the lawn area stays comfortably within its stated limit.
The Key Differences
- Price: The Anthbot M5 LiDAR has the lower MSRP at $799.00, while the Sunseeker S4 is $999.99.
- Coverage: The Sunseeker S4 lists a larger maximum mapping area at 0.25 acre (10,890 ft²), compared with the Anthbot M5 LiDAR’s up to 500m².
- Slope handling: The Anthbot M5 LiDAR is rated slightly higher at 45% / 24°, versus 42% / 22° for the Sunseeker S4.
- Cutting height information: Anthbot lists 3 to 7cm app-adjusted cutting height; Sunseeker does not list cutting height.
- Runtime details: Sunseeker lists 80 minutes charging time and 90 minutes mowing time per charge; Anthbot does not list runtime or charging on the product page.
Which Should You Buy?
Choose the Sunseeker S4 if your yard is closer to the upper end of this comparison, you want the larger manufacturer-listed maximum mapping area, and you value having charging and mowing time listed up front. It is also the better fit if your lawn is not Zoysia or St. Augustine, since Sunseeker says the S4 is not compatible with those grass types.
Choose the Anthbot M5 LiDAR if your yard is smaller, more enclosed, and you want the lower MSRP. It is the more obvious pick for a compact garden where 500m² is enough and where a wire-free, no-RTK mower is the priority.
If your main concern is slope, the Anthbot has the edge on paper. If your main concern is coverage and more complete published runtime details, the Sunseeker is stronger. For homeowners trying to keep costs down on a small shaded yard without RTK, the Anthbot is the more budget-friendly starting point.
Bottom Line
In the Sunseeker S4 vs Anthbot M5 LiDAR comparison, the Sunseeker is the better choice for buyers who want more mapped area and published runtime details, while the Anthbot is the better value for compact yards and tighter budgets. Both are wire-free, no-RTK robot mowers, but the Sunseeker is the more spacious option and the Anthbot is the cheaper one with a slightly stronger slope rating.
