Key Takeaways
1. Sunseeker is expanding into the European market and introduced the V3 series and X series of robotic lawn mowers last year.
2. The Sunseeker S4 model is set to launch in 2026, priced at $1,599, with preorders available and deliveries starting in March.
3. The S4 utilizes LiDAR technology instead of an RTK antenna for mapping and obstacle avoidance, following a trend among other brands in the industry.
4. Key features of the S4 include a 360-degree LiDAR sensor, AI camera, automatic mapping, and edge-following mode for efficient lawn care.
5. The mower can handle yards up to 10,800 square feet and manage slopes of up to 42% (22 degrees).
Last year, Sunseeker revealed plans to break into the European market. During that announcement, they also unveiled the V3 series of camera-based robotic lawn mowers and the X series, which includes RTK mower robots.
Upcoming Models in 2026
Looking ahead to 2026, more models are expected to be added to the company’s offerings. They have already confirmed the Sunseeker S4 and even displayed it at CES 2026 in Las Vegas a few weeks ago. The new robot mower’s official release seems to be just around the corner, as it is already available on websites like Amazon. Specifically, it is priced at $1,599 and can be preordered now, although deliveries in the US won’t happen until March 10. It remains uncertain whether this price is a special launch rate or the standard MSRP.
Technology Used in the S4
What stands out is that the Sunseeker S4 does not use an RTK antenna; instead, it relies on LiDAR technology. This aligns with a growing trend among various manufacturers who are also adopting this tech, which is mainly recognized from robotic vacuum cleaners. In the lawn care space, brands like Dreame, Mova, Roborock, Navimow, and Ecovacs have already embraced LiDAR. Regardless, the S4 combines a 360-degree LiDAR sensor with an AI camera, branding this as the “Allsense 3D Sensing System,” which promises precise mapping and effective obstacle avoidance.
Features and Capabilities
In addition to radar-based automatic mapping that comes with a “Drop to Go” function, the Sunseeker S4 is capable of handling yards up to 10,800 square feet, or about 0.25 acres. It also includes features like an edge-following mode for trimming along borders and dual map storage for managing different lawn areas. To top it off, it can manage slopes of up to 42% or 22 degrees.
