Segway Navimow i105N Review: Wire-Free Robot Mowing, Tested
No boundary wire, RTK-level GPS precision, and a mowing pattern that actually looks planned. Here’s what a season with the Navimow i105N tells you about wire-free robot mowing in 2026.

Segway’s Navimow i-Series ditched the buried boundary wire that defines most robot mowers, using a combination of RTK GPS and onboard vision (Segway calls it Exact Fusion Locating System) to map and navigate your yard instead. The i105N is the entry-size model in the lineup, built for yards roughly 1/8 acre — a smaller-lawn model. Here’s how it holds up.
| Spec | Detail |
|---|---|
| Coverage area | Up to ~1/8 acre (~5,400 sq ft) |
| Navigation | RTK GPS + vision-assisted (EFLS), no boundary wire required |
| Setup method | App-based virtual boundary mapping |
| Cutting width | ~7.1 inches |
| Slope handling | Rated for moderate slopes (check manufacturer spec for your yard’s grade) |
| App features | Scheduling, multi-zone mapping, no-go zones, mowing pattern selection |
| Weatherproofing | IPX6-rated, designed for outdoor use in rain |
Setup: The Real Advantage
The headline feature is skipping the trench-and-bury boundary wire process that eats up a weekend with most traditional robot mowers. Instead, you walk the perimeter of your yard once with the mower in a guided setup mode (or trace it in the app on some models), and the RTK GPS system remembers the boundary. For yards with a simple perimeter and a few obstacles — flower beds, trees, a shed — this cuts setup time from a full day to under an hour in most cases.
Mowing Pattern & Cut Quality
Where a lot of budget wire-free mowers wander in a semi-random pattern, the i105N drives in visible parallel lines — similar to a pattern a person would choose — which leaves a noticeably more even, striped look and covers the yard more efficiently per charge cycle. It handles narrow side-yard passages and tight turns around obstacles well, though very tight or oddly shaped zones can still occasionally require a manual no-go zone adjustment in the app.
Pros
- No boundary wire trenching required, cutting install time dramatically
- Planned mowing pattern gives a noticeably cleaner, more even cut than random-pattern mowers
- App-based multi-zone mapping makes complex yards (multiple sections, narrow passages) manageable
- RTK GPS precision keeps the mower reliably inside boundaries once mapped correctly
Cons
- Initial setup and mapping takes patience to get right, especially on irregular yards
- GPS accuracy can degrade near heavy tree cover or tall structures
- Higher upfront cost than wired boundary-based robot mowers of similar cutting width
- Steep or heavily obstructed yards may need a wired model instead

How It Compares to Wired Robot Mowers
| Navimow i105N (wire-free) | Typical wired boundary mower | |
|---|---|---|
| Setup time | Under an hour for simple yards | A half-day to full day for wire trenching |
| Mowing pattern | Planned, parallel-line pattern | Usually random/bounce pattern |
| Best for | Moderate-complexity yards without heavy tree cover | Yards with dense tree cover or GPS interference |
| Boundary changes | Update the map in-app | Requires re-trenching wire |
