At Equip Exposition 2025, a leading North American event for outdoor power and landscape professionals, Sunseeker introduced the S4, the brand’s first lidar robotic mower in the U.S. market.
Designed for wire-free deployment and precise mapping, the S4 addresses demand for smarter, low-maintenance lawn care, according to Sunseeker. The company also confirmed that the Sunseeker Elite X7 received its 2025 software enhancements. Sunseeker also briefly previewed an industry-first Zero-Edge Cutting system, which is expected to launch next year.
Built on the AllSense™ 3D sensing architecture with 360° LiDAR and an AI camera, the S4’s perception stack possesses more than 210,000 points per second and achieved a perception-to-decision response of approximately 0.125 seconds, delivering a 360-degree by 70-degree-wide field of view. This enables real-time 3D mapping and omnidirectional obstacle avoidance, ensuring precise navigation around both static and moving objects.
The setup is completely wire-free and antenna-free. With Drop to Go, the mower can be ready to start in about two minutes, while AI-powered automatic mapping creates virtual boundaries and mowing routes with minimal user input. Sunseeker stated an industry-leading 10 TOPS upgraded chip provides the computing power for real-time perception and mapping, stabilizing operation in complex yards and improving cut consistency along edges and narrow strips.
In 2025, the X7 model received software enhancements focused on everyday efficiency and reliability, including enhanced object recognition (200-plus classes), automated weekly scheduling that factors lawn size and daylight hours and smarter mapping utilities such as an auto heat map for optimizing RTK base-station placement and real-time boundary adjustment during mapping. Together, these capabilities translate the X Series’ three core systems (Full Auto-Driving, Efficient and Perfect Mowing and All-Terrain Conquer) into improved results, delivering more dependable operation and a cleaner, more consistent finish, according to the company.
The company also briefly previewed its Zero-Edge Cutting system, which is designed to cut right to the boundary to further refine the finish without changing current workflows, all with availability expected next year. In addition, Sunseeker will introduce its new 5-Fusion Positioning System to deliver enhanced perception and precision.
“We exist to bring intelligent, high-tech and eco-friendly outdoor equipment to every lawns and to make the experience truly effortless,” said Justin Novosel, executive vice president of Sunseeker. “By infusing cutting-edge technologies into lawn care, we aim to set new standards for how people shape and enjoy their outdoor spaces, making lawn care smarter, greener and more rewarding for households and professional crews alike.”
