Sunseeker S4 Wireless AI Robot Lawn Mower | 0.25 Acre

The Sunseeker S4 is a fully autonomous, wire-free robot lawn mower for lawns up to 0.25 acres (10,890 sq ft). It uses automotive-grade 3D LiDAR paired with AllSense™ Vision AI to map and mow complex yards — shaded areas under mature trees, tight corridors, and multi-zone layouts where GPS-only mowers lose their signal. A CES 2026 Innovation Award honoree.

Why the Sunseeker S4

• ✅ 3D LiDAR navigation — Automotive-grade 3D LiDAR builds a precise map and stays accurate under dense tree canopy and along tall structures, even at night.
• ✅ AllSense™ Vision AI — A 10 TOPS AI chip fuses LiDAR with camera vision for 360° obstacle avoidance around toys, hoses, pets, and furniture.
• ✅ Wire-free setup — Map your yard in minutes by walking the mower through it in the app — no perimeter wire to bury and no RTK base station to mount.
• ✅ Handles real yards — Climbs 42% (22°) slopes and crosses narrow passages down to 31.5 in (80 cm) between beds and obstacles.
• ✅ Multi-zone management — Create up to 100 zones across 5 maps, each with its own schedule, cutting pattern, and priority.
• ✅ Set-and-forget operation — Rain sensor, auto-recharge, OTA updates, and app scheduling keep it running with minimal supervision.

How to Use

Install the charging station on open, flat ground and dock the S4. Connect it in the Sunseeker app over Bluetooth and Wi-Fi, then map your lawn once by letting it scan the boundary (a typical quarter-acre takes 20–30 minutes). Set your zones and schedule, and the S4 mows on its own, returning to the dock to recharge. Most owners complete setup in about an hour.
