Product Description

This bundle pairs the Sunseeker S4 LiDAR robotic mower with a spare Sunseeker blades kit; both items ship together.

The Sunseeker S4 is a wire-free robotic mower for lawns up to 0.25 acre that navigates with 3D LiDAR rather than satellite signals. Because it scans its surroundings to build a precise 3D map of the yard, it does not need a clear view of the sky, which makes it well suited to properties with large trees, heavy shade, tall structures, and narrow paths where GPS-based mowers can drift. LiDAR is fused with Sunseeker's AllSense Vision AI for obstacle recognition.

Sunseeker Blades Kit: one package of 12 replacement blades and 12 screws, compatible with Sunseeker X7, S4, X5, X3 Plus, V3, and L22 robot mowers.

S4 Key Features

  • 3D LiDAR navigation: scans more than 210,000 points per second with 172-channel laser precision, a 360° × 70° detection angle, and a detection range of about 164 ft (50 m) for centimeter-level positioning
  • AllSense Vision AI fusion: AI-assisted camera sensing combined with LiDAR (L-SLAM + V-SLAM), processed on a 10 TOPS chip that Sunseeker rates at twice the power of its previous chip
  • Wire-free setup: no perimeter wire and no RTK antenna; map the yard in minutes by guiding the mower around it in the app
  • Obstacle avoidance: 360° detection using LiDAR, AI vision, and a floating bumper, designed to steer around pets and yard debris
  • Terrain handling: rear-wheel drive with off-road wheels climbs slopes up to 42% (22°), rolls over small obstacles up to 1.4 in (3.5 cm), and fits through passages 31.5 in (80 cm) wide or more
  • Cutting options: a floating cutting disc that follows the turf, ride-on-edge and edge-reach cutting, spot mowing, and custom, checkerboard, or crisscross mowing patterns
  • Automatic recharging: returns to the charging station when the battery drops below 30%, by a direct path, along the edge, or via a smart return route
  • App and smart home: Sunseeker app for scheduling, personalized cutting settings, and multi-map management with up to 100 zones; works with Alexa and Google Assistant and receives over-the-air updates
  • Built for outdoor use: IPX6 water resistance, rain sensor, low-noise operation at 60 dB(A) or less, and GDPR data protection
  • Optional security: a 4G-GPS anti-theft module is available separately
