The proof

Don't take our word for it

Three independent YouTube creators put the Sunseeker S4 to the test — including two head-to-head faceoffs against other top LiDAR mowers.

Common questions

How is the S4 different from other robot mowers?

Most robots rely on GPS or a buried boundary wire. The S4 uses 3D LiDAR + Vision AI to map your yard with no wire and no RTK antenna — so it holds its place under trees, avoids obstacles, and manages multiple zones on its own.

Do I need to bury a boundary wire?

No. You walk the perimeter once in the app and the S4 maps it. No trenching, no wire — and it's more precise than wire once set.

Do I need an RTK antenna?

No. Unlike many robot mowers, the S4 maps and navigates with 3D LiDAR and vision — there's no antenna or base station to mount in your yard.

Will it work under trees or in shade?

Yes. The S4's LiDAR doesn't depend on a clear sky the way GPS-only mowers do, so it keeps its position under canopy where those rivals drift or stall.

How big a yard does the S4 cover?

The S4 is built for properties up to about a quarter acre, and manages up to 100 zones across 5 maps.
