Segway Navimow i105N

The Navimow i105N is the entry ticket to wire-free mowing from a brand with a track record. Segway rates it for lawns up to 1/8 acre with slopes no steeper than 30 percent, and every independent source we read agrees on the qualifier: small, flat and open. Reviewed ranked it best value in its real-yard guide, and MowScout's September 2026 assessment calls it the value entry point to wire-free mowing while telling buyers with shade, slopes or more than about 0.15 acre to look elsewhere.

It suits a suburban front-and-back lawn with a clear view of the sky, a level spot for the dock and an owner who would rather trim a few edges by hand than pay for an all-wheel-drive machine.

Quiet. At 58 dB(A) it is the quietest mower in our comparison, 10 dB below the spec-sheet figure for the Navimow X430. That matters for a small mower that needs several runs a week to keep up.

Hybrid RTK and vision positioning. Segway's EFLS 2.0 combines RTK satellite corrections with visual SLAM from a forward camera. RC Ratings describes a 140-degree camera that recognizes more than 150 object types, and the same review found the combination coped with scattered trees and narrow corridors. Light shade is fine; heavy canopy is not, as the next section explains.

Simple, robust hardware. It weighs 24 lb, carries an IP66 rating, runs about 60 minutes per charge from a 2.55 Ah pack and recharges in about 90 minutes. The 7.1 in three-blade deck mulches clippings, and Top Ten Reviews found the result comparable to a walk-behind mower on its test lawn.

Three-year warranty. MowScout lists a three-year warranty, the same term Mammotion gives the LUBA 3 two price classes up, and longer than most mowers in this class.

Setup a novice can finish. Top Ten Reviews found pairing quick, the printed instructions clear and the mapping straightforward, and boundaries or no-mow areas can be redrawn in the app at any time without touching a wire.

It needs a staked antenna. The X430, WR320 and LUBA 3 pull RTK corrections over the network; the i105N ships with a physical RTK antenna on a stake. Top Ten Reviews says it has to be more than 2 m from buildings and large obstacles with a clear sky view, and owner reports collected by Bikman Tech list weak GPS signal as a recurring complaint.

Trees and fences are its weakness. MowScout advises skipping it under heavy tree cover, and the same owner reports mention mapping trouble on complex lawns. A tall solid fence along a narrow strip blocks part of the sky, which is where an RTK-first mower loses its fix.

The dock must be dead level. Top Ten Reviews had to relocate its charging station after an initial failure because the base tolerates almost no incline, and found the carry handles awkwardly placed on the underside.

Narrow cut, slow coverage. At 7.1 in and 60 minutes per charge it covers a fraction of what the X430 does per hour, which is why the rating stops at 1/8 acre. Reviewed found the cut less consistent near edges, and RC Ratings notes owners should expect it to work slowly.

Height and market confusion. The US i105N adjusts manually from 2.0 to 3.6 in, per Wellbots, SLE Equipment and Top Ten Reviews, while listings for other markets show 0.8 to 2.4 in. Check the range on the listing you buy, and note that the US version cannot go below 2 in for a tight cut on Bermuda or zoysia.

The Worx Landroid Vision Cloud WR320 is the natural step up. It covers four times the lawn, uses antenna-free RTK Cloud with lifetime free service, adds electric height adjustment and has a V-SLAM fallback that Robot Review Desk credits with holding orientation under trees. It shares the i105N's 30 percent slope limit and two-wheel-drive layout, so neither belongs on a hill.

The Segway Navimow X430 is the same app and ecosystem with everything the i105N lacks: all-wheel drive, an 84 percent slope rating, a 17 in deck, network RTK and 360-degree cameras. It is a different class of machine and a different price class.

Buy the i105N if your lawn is small, flat and open to the sky, and you want a budget-class wire-free mower from a major brand with a three-year warranty. Skip it if you have heavy shade, a real slope, more than about 0.15 acre or a yard chopped up by fences and gates; the WR320 or the X430 will save you the frustration.
