Full specifications
Below is the full hardware sheet we pulled directly from Segway for the Navimow i108E, cross checked against current product documentation so you can size it against your yard before buying. On paper this machine pairs. It handles slopes up to ~24° (≈45%), which is the number that usually decides whether a mower will work on a given lawn.

Standout features
These are the specific things the Navimow i108E does better than the average robot mower in its price band. We pulled them from manufacturer documentation and aggregated long-term owner feedback, and weighted features that actually change day to day mowing rather than spec sheet trivia.
- • Fast auto-mapping
- • Centimeter-accurate RTK navigation
- • Quiet operation
Pros
The strengths below are the reasons buyers keep the Navimow i108E after the novelty wears off. Each point reflects something owners consistently confirm in long-term reviews or that Segway backs with a clear specification, not marketing language.
- + Centimeter-accurate RTK keeps lines tight
- + App auto-maps in one perimeter walk
- + Library-quiet at the edge of the lawn
- + Geofencing and PIN lock built in
Cons
Every robot mower involves trade offs. The drawbacks below are the ones most likely to bite a real owner of the Navimow i108E, ranked by how often they come up in long term use rather than by how dramatic they sound on a feature list.
- − RTK needs reasonably clear sky
- − Not for slopes above 25°
- − Multi-zone setup is fiddly across driveways
Who it's for
The Navimow i108E is built around a specific kind of lawn and a specific kind of owner. If your yard and habits match the profile below, it tends to be one of the easiest robot mowers in its class to live with. Best fit categories on our list: small-yards, wire-free.
Small to mid lots up to ~8,700 sq ft where boundary wire would be a hassle.
Who should skip
Picking the wrong robot mower is expensive, so it is worth being honest about who should walk away from the Navimow i108E. If any of the situations below describe your yard, expect frustration and look at one of the alternatives at the bottom of this review instead.
Properties bigger than a quarter acre, or yards tucked under dense tree canopy.
Setup
Because this model is wire free, setup is mostly an app driven mapping walk rather than a trenching job, which is the biggest practical reason most buyers choose it. The RTK reference antenna needs a clear view of the sky, so dock placement matters more than people expect.
Dock + RTK antenna with sky view + one app-guided perimeter walk. Usually under 30 minutes.
Real-world performance
Spec sheets only get you so far. This is how the Navimow i108E actually behaves once it is mapped, scheduled and left to run for a few weeks across a real lawn with kids, pets, sprinklers and the occasional fallen branch in the way.
Even, parallel pattern with sharp edge work for an RTK mower. Handles light obstacles well.
App experience
Most of the daily relationship with a robot mower happens inside its phone app, not on the mower itself. The Navimow i108E is controlled from the Segway app on iOS and Android, and the quality of that software has a bigger effect on satisfaction than almost any hardware spec.
Scheduling, no-go zones, manual zones, and rain delay all live in the Navimow app.
Noise
Robot mowers earn their keep partly by being quiet enough to run at hours a gas mower never could. The Navimow i108E is rated around a low decibel level typical of cordless robot mowers at operator distance, which is the number that decides whether you can schedule it at dawn without a neighborly conversation.
Around 54 dB at one meter — fine for early-morning runs.
Maintenance
A robot mower is a small outdoor robot that lives in your grass, so it needs a little routine care to keep cutting cleanly and to hit its warranty period. Below are the maintenance tasks specific to the Navimow i108E.
Swing-blades every 1–3 months. Winter storage indoors above 32°F.
