At CES 2026, Sunseeker is drawing attention not with flashy concepts, but with a practical rethink of how robotic lawn mowers should actually work. The Sunseeker S4 is built for everyday homeowners who want autonomy without complexity—delivering advanced sensing, intelligent navigation, and professional-looking results without wires, antennas, or lengthy setup.
Rather than positioning the S4 as an experimental gadget, Sunseeker frames it as a mature, ready-for-real-life solution aimed squarely at modern residential lawns.
Drop-and-Go Setup Eliminates the Biggest Barrier to Robotic Mowing
One of the most frustrating aspects of robotic lawn mowers has always been installation. Boundary wires, calibration passes, and constant adjustments often turn “automation” into a weekend project. The S4 removes that barrier entirely.
Thanks to its LiDAR-based perception system, the S4 requires no perimeter wires and no external antennas. Users simply place the mower on the lawn, connect it to Wi-Fi, and let it begin learning about the environment. The mower automatically maps the yard in 3D, identifying boundaries, pathways, and obstacles without manual input.
This “drop and go” experience dramatically shortens the learning curve and makes robotic mowing accessible to users who might otherwise avoid it altogether.
3D LiDAR and AI Vision Work Together in Real Time
At the heart of the S4 is Sunseeker’s AllSense™ 3D Fusion Sensing System, which combines high-precision LiDAR with an AI camera. The mower processes hundreds of thousands of data points per second to build a detailed understanding of its surroundings.
This allows it to:
- Detect and avoid static objects like stones and furniture
- Respond to moving obstacles such as pets or toys
- Recognize edges, drop-offs, and elevation changes before reaching them
Rather than reacting after contact, the S4 anticipates obstacles and reroutes smoothly, resulting in fewer interruptions and safer operation.
Intelligent Path Planning for Cleaner, More Consistent Results
Beyond avoiding obstacles, the S4 focuses on mowing quality. Its intelligent path-planning system creates structured mowing patterns that resemble professionally maintained lawns, even in irregularly shaped areas.
For complex yards, the mower can divide the space into sub-zones, ensuring even coverage and minimizing missed patches. Edge cutting is adaptive as well—the S4 adjusts its behavior depending on whether boundaries are clear or partially blocked, reducing the need for manual trimming afterward.
The result is a lawn that looks intentionally maintained rather than randomly cut.
Designed for Real-World Lawns, Not Ideal Conditions
Sunseeker also engineered the S4 to handle the realities of everyday outdoor environments. A dual-wheel rear drive and off-road traction allow it to climb slopes and maintain stability on uneven ground. Built-in rain detection, lift alerts, and automatic recharging help the mower operate reliably with minimal oversight.
Key capabilities at a glance:
- Wire-free, antenna-free installation
- LiDAR + AI vision for 360° obstacle avoidance
- Intelligent zone and multi-area management via app
- Adaptive edge cutting for cleaner boundaries
- Stable operation on slopes and uneven terrain
At CES 2026, the Sunseeker S4 is delivering autonomy that already feels practical. It’s a reminder that the most meaningful innovations aren’t always the loudest ones, but the technologies that quietly remove friction from everyday life.
