Segway Navimow i105N vs eufy Robot Lawn Mower E15
Two wire-free robot mowers for a small yard at very different prices — buy the Navimow to spend less on a proven RTK setup, or the eufy to skip antennas entirely and get built-in anti-theft.

How they differ in real use
Both of these skip the buried boundary wire, but they get there by different routes, and the gap in price is the headline. The Segway Navimow i105N (around $669) pairs RTK satellite positioning with a 140-degree VisionFence camera: RTK gives it a precise fix on where it is, and the camera enhances that and spots obstacles, recognizing 150-plus common garden objects. The eufy E15 (around $1,200) drops RTK altogether and navigates by pure vision — stereo cameras and AI SLAM do all the mapping and positioning. In practice, the Navimow's RTK is the more robust locating method on an open lawn but wants a clear sky view, so a heavily wooded lot can trip it up; the eufy's camera-only approach avoids antenna placement entirely and sets up fastest, but it's the more likely of the two to lose its way on a complex or irregular lawn. The feature sheets diverge on the extras that matter for a robot left outside: the eufy includes built-in GPS anti-theft and automatic recall in rain or low light as standard, while the Navimow makes GPS tracking an optional 4G add-on. Slope tolerance favors the Navimow (30% versus the eufy's gentler 18°), and coverage favors the eufy (about 8,700 sq ft versus the Navimow's ~5,400). For most flat, open small yards the Navimow does the same core job for roughly half the money; the eufy earns its premium only if wire-free-and-antenna-free simplicity plus out-of-the-box anti-theft are worth it to you.
Segway Navimow i105N
- Fully wire-free RTK + Vision setup — no perimeter cable to lay
- Camera recognizes 150+ obstacle types instead of just bumping into them
- Quiet 58 dB operation is fine to run near a patio
- Strong value: wire-free convenience at a mid-tier price
- RTK relies on a clear sky view — heavily wooded lots can lose signal
- GPS anti-theft tracking requires the optional 4G add-on module
- Covers small-to-mid lawns, not large properties
eufy Robot Lawn Mower E15
- Pure-vision navigation: no boundary wire and no RTK antenna to place
- Built-in GPS anti-theft tracking as standard
- Auto-recall to base in rain or low light
- 3D obstacle avoidance for rocks, toys, and pool borders
- Camera-only navigation can lose its way on complex or irregular lawns
- One of the pricier picks for a small-yard robot
- Limited to gentle 18° slopes and grass under 3.5 inches
Which should you buy?
Choose the Segway Navimow i105N if value matters and your lawn has a reasonable sky view — you get wire-free RTK setup, capable AI obstacle avoidance, and 30% slope handling for close to half the eufy's price, and you can add 4G GPS tracking later if you want it. Choose the eufy E15 if you want the absolute simplest setup — no wire and no RTK antenna — plus built-in GPS anti-theft and rain auto-recall out of the box, and your yard is fairly open and flat enough for camera-only navigation to stay on track. On a steeper lot, the Navimow's higher slope rating is the tiebreaker; on a larger small lot near 0.2 acre, the eufy's bigger coverage helps.
Choose the Segway Navimow i105N if
- Small, mostly open yards that want wire-free setup
- Buyers who want AI obstacle avoidance without a premium price
- Lawns with beds, trees, and narrow passages to navigate
Skip it if
- Heavily wooded lots where RTK can't get a clear sky view
- Large properties beyond a quarter acre
Choose the eufy Robot Lawn Mower E15 if
- Simple, open small lawns that want zero-install setup
- Buyers who want built-in anti-theft and rain auto-recall
- Households that will manage zones and scheduling from the app
Skip it if
- Complex, fragmented, or heavily obstacle-filled yards
- Slopes steeper than 18°
Common questions
What's the real difference between RTK and pure-vision navigation?
RTK uses satellite positioning for a precise location fix and works well on open lawns but needs a clear view of the sky, so tree cover can interrupt it — the Navimow i105N uses RTK plus a camera. Pure vision, as on the eufy E15, uses only cameras and AI to map and navigate, which removes any antenna setup but is more prone to getting confused on complex or irregular layouts.
Does either one include GPS anti-theft?
The eufy E15 has built-in GPS anti-theft tracking as standard. The Segway Navimow i105N offers GPS tracking only through an optional 4G add-on module, so if theft tracking out of the box matters to you, the eufy has the edge.
Which handles slopes and bigger small lawns better?
The Navimow i105N handles steeper ground, rated to 30% versus the eufy E15's gentler 18° limit. For coverage it's the reverse — the eufy is rated for about 0.2 acre (~8,700 sq ft) against the Navimow's roughly 1/8 acre (~5,400 sq ft).
