The Sunseeker S4 is a wire-free robotic lawnmower from Sunseeker designed for medium-sized yards up to 0.25 acres that feature complex layouts, such as tight passages, trees, flower beds, and shaded areas where GPS-based navigation struggles. It uses a combination of 360° 3D LiDAR and Vision AI for navigation and obstacle detection, positioning it as a more sensor-rich option within the sub-0.25-acre robotic mower segment. The S4 is a CES Innovation Awards 2026 Honoree and sits in the middle of Sunseeker's current product lineup, which spans from the V3 to the X7 Plus.
