Segway Navimow X315e: the big brother of the H1500E is here

Introduction

After an entire season using the Segway Navimow H1500E, which had already profoundly changed my relationship with mowing, I had the chance to participate in the beta testing program for the new Navimow X315E. This model builds on the solid foundations of the H1500E while introducing significant innovations that go far beyond a simple evolution. Let’s be clear from the start: the X315E is shaping up to be a serious contender for the title of must-have robotic mower.

An installation that remains incredibly simple

One of the major advantages of the Navimow range is the wireless peripheral installation. Once again, the setup is quick and smooth. The virtual map is intuitive, and the integrated screen provides real comfort with real-time feedback on the robot's operation. I also received a second RTK antenna, which I placed in a less exposed area of the garden. The result: impeccable GPS coverage, even in shadier corners.

Smarter navigation thanks to EFLS 3.0

The X315E features the new EFLS 3.0, which combines RTK (Real Time Kinematic), VSLAM (Visual Simultaneous Localization and Mapping), and VIO (Visual Inertial Odometry). This allows for ultra-precise navigation, even in cases of weak or unstable GPS signals. The robot always knows where it is, adapts its trajectory in real time, and perfectly respects the defined boundaries. Even in complex environments, the X315E maintains impressive accuracy.

Cameras for reliable obstacle detection

Another major innovation is the addition of cameras and a 300° vision system, coupled with artificial intelligence to detect obstacles. And this is not just a gimmick. Even at night, thanks to its integrated headlights, the robot spots and avoids objects or animals—including small ones like hedgehogs—without getting into trouble. It’s astonishing to see it do the work without human intervention. It’s also important to note that the version I received during the beta testing program is the one equipped with stereo cameras at the front. It’s good to know that two technologies were tested in A/B testing: one version with stereo vision and one version equipped with ToF (Time of Flight). This allowed Segway to better calibrate and find the most effective solution for positioning the robot.

Mowing performance and daily operation

Mowing is quick, clean, and well-structured. Despite being slightly larger than the H1500E, the X315E navigates narrow passages without issue. It climbs slopes of up to 50% with ease and strictly adheres to the programmed schedules. The paths are coherent, the edges are well managed, and above all, it knows how to adapt to the irregularities of the terrain. On a daily basis, it’s a discreet, reliable, and incredibly effective robot.

The trimmer option: useful, but not for everyone

Segway offers an optional trimmer module to attach to the robot. On paper, it’s an excellent idea, especially for corners or edges that a robot can’t always manage well. But in practice, this option quickly shows its limitations in a large garden. Indeed, based on the tests I conducted, it turns out that you need to manually control the robot and follow it closely to trim the edges. For a large area, this is clearly not a sufficient solution. In my opinion, if you’re going to go around anyway, a traditional trimmer will be much more effective. Additionally, the design of the trimmer means that freshly cut grass is projected onto the robot, which gets it quite dirty.

Finally, I consider the trimmer to be a gadget in a medium to large garden. However, I see an advantage in an urban garden, where going around to trim the edges takes less time, and it also avoids the need to store an additional trimmer.

A promising beta version, awaiting the final version

It’s important to clarify that the model I tested is a beta version. Therefore, I do not yet have the final version of the X315E in my hands. This means I cannot yet assess the materials, finish, or color choices. I look forward to discovering the final version to get a clearer idea of these aspects.

Despite this, the robot has proven to be surprisingly stable. The minor bugs encountered were few and largely expected for a testing phase. What really impressed me was the responsiveness of the development team: updates were almost weekly, quickly addressing identified issues. This active and rigorous follow-up is reassuring and shows that the product is in good hands.

Conclusion

The Segway Navimow X315E confirms that Segway has a solid grasp of robotic mowing. With its simplified installation, ultra-precise navigation, built-in intelligence, and well-thought-out options, it ticks almost all the boxes. If it lives up to its promises until the final version, it could very well become the new benchmark in autonomous mowers. For my part, I am already convinced of its potential.
