WHY THIS FEELS SELF-DRIVING —NOT JUST "SMART"

Many mowers claim smart navigation. S4 is engineered with a full perception-to-execution system built for real, imperfect yards.

Perceive

LiDAR-led 3D mapping + systematic routes help S4 stay predictable in the yard.

More stable behavior near trees, walls, and tight corners.

Plan

Builds a precise map and routes systematic mowing paths—zone by zone.

More predictable coverage with less wandering and fewer missed areas.

Execute

Maintains consistent motion control and cutting behavior in real conditions.

Cleaner results with fewer interruptions.

Advanced Capabilities

MADE FOR COMPLEX YARDS

LiDAR + AI Vision navigation, wire-free setup, and systematic cutting for yards up to 0.25 acre / 1000 m².
