Sunseeker S4 vs Anthbot M5 LiDAR
Quick take: The Anthbot M5 LiDAR costs $200 less; the Sunseeker S4 is rated for a larger lawn (10,890 sq ft); the Anthbot M5 LiDAR is rated for steeper ground (45%); the Sunseeker S4 cuts taller (up to 3.2"), which matters for fescue and warm-season grasses; the Anthbot M5 LiDAR has built-in cellular for GPS tracking and away-from-home control.

Pros & cons
Sunseeker S4
- ✓No antenna, no wire: LiDAR maps and positions under tree canopy where GPS mowers drift
- ✓Auto-mapped a two-zone yard on the first try; the app shows the 3D LiDAR map it built
- ✓Reliably rerouted around a dog and a golf-ball-sized toy in a month-long test
- ✓Fits through 31.5 in passages and stores 100 zones across 5 maps
- ✓Cheapest LiDAR mower from an established brand, $500 under the Ecovacs O1000 LiDAR Pro
- ✗Blades sit 4.3 in inside the housing, so it leaves an uncut strip at every edge
- ✗7 in deck and 90 minute runtime mean a quarter acre takes several charge cycles
- ✗One review unit died after a night in standing water despite the IPX6 rating
- ✗GPS tracking needs the extra-cost 4G module
Anthbot M5 LiDAR
- ✓Nothing to mount: no RTK station, no wire, mapping in minutes
- ✓LiDAR keeps position under trees and beside buildings where the RTK M5 drops out
- ✓Fine-grained edge behaviour settings per boundary type reduced trimming in testing
- ✓Resumes its row after an obstacle instead of leaving strips
- ✓Rain sensor, 20 zones and IPX6 for the same money as many RTK-only mowers
- ✗About 40 minutes per charge on a 2.5 Ah pack, so even 500 m2 takes several cycles
- ✗Slight snaking through narrow passages compared with RTK positioning
- ✗Two-wheel drive; not for lumpy or steep ground
- ✗4G monitoring becomes a paid service after the trial
