Overview
The S4 ($1,299) is a robot mower from Sunseeker. It is rated for lawns up to 1,000 m² and slopes up to 42%. Navigation: 360° 3D LiDAR + Vision AI.
Compact LiDAR mower for a quarter acre with AllSense vision obstacle detection.
On paper it suits typical suburban gardens — the manufacturer rates it for up to 1,000 m². The 42% slope limit makes it a better fit for flat or gently sloping lawns. As always, treat the area figure as a best case: buy with a 30–50% buffer if your lawn has slopes, trees or narrow passages.
Its LiDAR sensor scans the garden in 3D and lets the mower localise itself against that map, so it keeps working under trees, next to house walls and at dusk — places where satellite-only mowers often lose their position.
It mows with a 18 cm cutting width and a cutting height of 40–81 mm. Cutting system: 1 floating disc, 6 blades.
Price: $1,299 (US list price). Prices vary by market and retailer — check current offers before buying.
