Reference Price
Currently listed at $799 on navimow.com and Home Depot. Top Ten Reviews cites a figure of $999–$1,000, which may reflect an earlier price point or a different bundle — $799 is Segway's current listed price.
Sensors & Hardware
Navigation uses EFLS 2.0 (RTK GPS fused with a 140° VSLAM camera) for centimeter-level positioning without a boundary wire. "VisionFence" obstacle avoidance uses the same camera claiming 150+ object types, though reviewers found path precision imperfect, occasionally leaving unmowed strips. A separate ~$150 4G module is required for remote monitoring and anti-theft/GPS tracking; base connectivity is Bluetooth/Wi-Fi only.
Insights
Segway rates the i105N to climb slopes up to 30% (about 17°), but independent testing of a closely related i-series model found real-world performance degrading above roughly 16° — near the advertised ceiling rather than safely under it. Price citations also diverge: Segway's own current listing and Home Depot show $799, while an older Top Ten Reviews figure cited $999–$1,000.
Firmware & Community
Closed platform
Segway Navimow i105N has not released a public SDK, firmware repo, or developer API. Not currently listed in Builds & Mods.
Verified against Segway's own official Navimow site (navimow.com, navimow.segway.com) and independent reviews from Consumer Reports, Top Ten Reviews, Android Police, and PCWorld (the latter covering the closely-related i110N). The "N" in "i105N" is a North American regional SKU designator, not a feature tier — the identical-hardware EU model is called "i105E." Slope rating is a manufacturer ceiling; at least one review of a related i-series model found real-world performance degraded above roughly 16° despite the 30% (~17°) spec. Price differs between Segway's current listing ($799) and an older Top Ten Reviews figure (~$999) — treat $799 as current.
