Product Description

This premium bundle combines the Sunseeker S4 LiDAR robotic mower, the Sunseeker S4 Sunproof Garage, and a spare Sunseeker blades kit; all 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 S4 Sunproof Garage: a durable platform-docking shelter that shields the S4 from sun and weather between mowing sessions while leaving it easy to access. It fits the Sunseeker S4 only and is not compatible with the X7 Plus, X7, X5, X3 Plus, or V3.

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
