Sunseeker S4 Robot Lawn Mower, 3D LiDAR, Vision AI, 0.25 Acre, Wire-Free + Blades

The Sunseeker S4 is a self-driving-level robotic lawn mower designed for the real, complex yards people actually live with – the ones with slopes, trees, toys, pets, and kids. Instead of testing only on flat, perfect lawns, S4 is built to handle medium-sized properties up to 1,000 m² (¼ acre) with uneven ground and multiple zones. At the heart of S4 is a LiDAR + AI Vision navigation system. By combining a laser sensor with an intelligent camera, S4 builds a 3D map of your property, plans systematic mowing paths and avoids obstacles in all directions. The result is a true self-driving-level mowing experience – efficient, predictable and easy to live with. Drawing on nearly 20 years of lawn & garden equipment experience, Sunseeker puts just as much care into cut quality as into navigation. The floating cutting deck follows the contours of your lawn, while the 18 cm blade and 20–60 mm height range deliver a clean, even finish. Perfect edge cutting lets S4 trim closer along driveways and borders, so there’s less work left for your trimmer. S4 eliminates the hassle of boundary wire with wireless virtual boundaries. Use the app to define your lawn, set no-go areas and fine-tune paths – and change them any time your yard changes. With 60 dB(A) low noise, IPX6 / IP67 weather protection, rain and lift sensors plus App/WiFi/Bluetooth connectivity, S4 is designed to fit into everyday life, not take it over. If you’ve been waiting for a robot mower that can truly understand your yard without costing two or three times as much, Sunseeker S4 brings self-driving-level mowing to the under-$1,000 segment – so you can spend less time rescuing your mower, and more time enjoying your yard.
