The Segway Navimow i208 is a wire-free robot lawnmower that uses solid-state LiDAR combined with onboard vision sensors for satellite-free navigation. No boundary wires. No RTK antenna. Just place it down and tap once to begin auto-mapping. It works day and night with full 3D awareness of its surroundings.
The 100W motor drives a 6-blade cutting disc across a 22 cm cutting width. Cutting height adjusts between 2 cm and 7 cm across 5 positions. It covers up to 265 m² per charge on a 5.1 Ah battery with roughly 110 minutes of runtime. The all-terrain wheels handle slopes up to 45% gradient (24°) with Electronic Stability Control keeping it steady.
AI VisionFence detects over 200 obstacle types with 1 cm accuracy. Manage up to 20 mowing zones via the app. GPS tracking, geo-fence alerts and Apple Find My integration add real security. Cellular connectivity is included free for the first year. This bundle includes the Garage M for weather protection when docked.
No. This is one of the key differences from older robot mower technology. The i208 uses solid-state LiDAR combined with vision sensors to map and navigate your garden automatically. There are no wires to bury, no antenna to install and no pegs to hammer in. You place the mower on the lawn, open the app and tap once to begin auto-mapping. The mower builds its own map of your garden and uses that for all future mowing sessions.
LiDAR (Light Detection and Ranging) fires rapid pulses of laser light to build a precise 3D map of the surrounding environment. The i208 pairs this with onboard vision sensors in what Segway calls EFLS (Efficient Fusion Localisation System). The result is stable navigation that does not depend on satellite signals. GPS-based systems can struggle under tree canopies or near buildings where signal is weak. The LiDAR system works reliably in those conditions and operates both day and night without any loss of accuracy.
The i208 is rated for slopes up to 45% gradient which equals approximately 24°. That is steeper than most robot mowers on the market. It achieves this using all-terrain off-road wheels and Electronic Stability Control which adjusts power to each wheel to maintain traction on uneven or sloped surfaces. The 100W motor provides sufficient torque to push through dense or fast-growing grass even on a gradient. One verified user with roughly 500 m² of complex uneven terrain reported it working well across the full area.
The 5.1 Ah battery provides approximately 110 minutes of mowing time per charge. In that time it can cover up to 265 m² per charge. The recommended total mowing area for this model is approximately 800 m² which it manages by returning to charge and resuming automatically. Charging and mowing cycles are handled without any input needed from you once the schedule is set up in the app.
The cellular (4G) connection allows the mower to receive positioning data and stay connected to the app even when your home Wi-Fi does not reach the garden. It also supports GPS tracking for security purposes. The first year of cellular connectivity is included free. After that the cost is approximately £30 per year (around 30€). If your garden has good Wi-Fi coverage you may rely on that instead. The mower also supports Bluetooth for close-range connection.
The mower has several layers of security built in. GPS tracking shows its location at all times. A geo-fence can be set so you receive an alert if the mower moves outside a defined boundary. Lift detection triggers an alarm if the mower is picked up without being deactivated first. Apple Find My integration works in the same way as an AirTag meaning it can be tracked through the Apple network even without cellular signal. Together these features make the mower a much harder target for theft than a standard robot mower.
Yes. The i208 is compatible with both Amazon Alexa and Google Home. You can start and stop mowing, send it back to dock and manage basic functions entirely by voice without touching your phone. This is useful when your hands are busy or you simply want a fully hands-free setup. Full scheduling and zone management still requires the app but day-to-day operation can be handled through your existing smart home system.
This listing includes the i208 LiDAR robot mower and the Garage M charging station. The Garage M is the medium-sized garage designed specifically for the i208 which is a larger machine than the previous i108 model (which used the smaller Garage S). The garage provides weather protection when the mower is docked and charging. It shields the mower from rain and direct sun which helps protect the battery and electronics over time. Note that the mower and garage may ship separately.
