i1 series (i105E, i105N, i108E, i110N)
Segway's first small wire-free mower, for fairly flat lawns up to 800m². Four reviewers liked its tidy striped cut and easy app, but it leaves a strip at the edges and its aerial needs open sky.
The short version
The i1 series is the mower that made Navimow a household name in small gardens. The i105E (i105N in the US) suits lawns up to about 500m², and the i108E stretches to 800m² with a bigger battery. The US also had an i110N for a quarter of an acre. It finds its way with satellites and a small aerial on a pole, helped by a front camera, so there's no boundary wire to bury. It mows in neat straight lines rather than wandering at random.
Its replacement, the i2 AWD, is already here, and Navimow's European stores had sold out of the i1 in September 2026. What you give up against the newer model is grip and convenience: it's two-wheel drive and rated for gentler slopes, you have to put up the aerial, and mobile data needs an add-on module. You also set the cutting height with a dial rather than in the app. Where it's still sold, it's $2,199 at the cheapest retailer we track.
Our take: Buy it if you have a small, open, mostly flat lawn and can find one at a good price while stock lasts. Reviewers found it cuts neatly and is easy to live with. If your lawn slopes, gets muddy or sits under trees, the Navimow i2 AWD grips better and needs no aerial, and the Mammotion YUKA mini 2 1000 copes better with shade.

What reviewers found
Four home tests. Expert Reviews and Trusted Reviews tried the UK i105E, Top Ten Reviews the US i105N, and Tom's Guide the bigger US i110N. All four liked the straight-line cut and the app, and all found you still need a strimmer along the borders. They differ on setup: Trusted Reviews was ready in about ten minutes, while Expert Reviews and Tom's Guide found steering it round the boundary fiddly. Obstacle spotting was good but not flawless.

A neat cut in straight lines
This is what reviewers liked most. Expert Reviews saw it mow in overlapping stripes, changing direction on each of four runs, and got a neat and tidy lawn. Top Ten Reviews had a clean cut on the first pass, dandelions included, and said it stuck to its boundaries very well. Trusted Reviews called the cutting excellent and never saw it stray into flower beds. Tom's Guide found no uncut strips or patches left mid-lawn. If a tidy look matters, this beats mowers that roam at random.
You'll still trim the edges
The blade disc sits in the middle of the body. Expert Reviews and Trusted Reviews both measured about 10cm left along walls, fences and beds, and Top Ten Reviews said you'll need a string trimmer for the borders. Where the lawn meets a flush path, a ride-on-the-edge mode lets it straddle the border: Trusted Reviews and Tom's Guide both found this cut right to the edge. Laying flat edging stones saves a lot of strimming.
Setup: quick for some, fiddly for others
Trusted Reviews had the dock and aerial in and the robot ready to map within ten minutes of unboxing, using a mix of automatic and manual edge-finding. Expert Reviews found steering it round the boundary with on-screen controls finicky and put a wheel in a flowerbed more than once. Tom's Guide got a near-perfect automatic map on a flat lawn, but on hilly sections it kept well clear of kerbs and fence posts. It also once fell into the street before its hand-drawn boundary was tightened.
Good at spotting things, not perfect
Trusted Reviews left out a table, shoes and a clothes horse, and the mower got close, then turned or went round each one. Top Ten Reviews stood in its path and it stopped and steered away. Tom's Guide saw it add a tree and a fountain to the map on its own. But Expert Reviews had it nudge a dog's ball on the first pass before avoiding it later. Small, low objects are the risk, so pick up toys first.
Mind the dock and the sky
The aerial needs open sky. Expert Reviews lists that as its main drawback, and Top Ten Reviews was told to keep it two metres from the house and trees. The dock is fussier than you'd think: Top Ten Reviews found the wheels slipped off it until it was moved to perfectly flat ground. On the lawn itself, Top Ten Reviews had no trouble with bumps or gentle slopes. This two-wheel-drive design is best on fairly flat, open ground.
This page covers the whole i1 series. Expert Reviews and Trusted Reviews tested the i105E, Top Ten Reviews the i105N (the US name for the same mower), and Tom's Guide the larger US-only i110N.

Before you buy
The questions people ask about this one
Does it need a boundary wire?
No. It uses satellite positioning with a small aerial on a pole, plus a front camera, per the specifications. You map the lawn by driving it round in the app, or let the camera find the edges. Trusted Reviews found that quick, while Expert Reviews found the steering finicky.
Will it cope with my slope?
It's rated for 30% (17°), per the specifications. Top Ten Reviews had no trouble with bumps and gentle slopes. Tom's Guide found its automatic mapping played it safe on hilly sections, keeping away from kerbs and fence posts. For a proper bank, the all-wheel-drive i2 AWD is rated for 45%.
Does it need a clear view of the sky?
Yes. The aerial needs open sky, and Expert Reviews lists that as its main drawback. Top Ten Reviews was told to keep it two metres from the house and big trees. If your lawn is heavily shaded, a mower that navigates without satellites may suit you better.
How close does it cut to the edge?
About 10cm short of walls and beds, according to both Expert Reviews and Trusted Reviews, because the blade sits in the middle. Along flush paths, a mode that straddles the edge let Tom's Guide and Trusted Reviews cut right up to it.
Is there a subscription for 4G or anti-theft?
Only if you want it. The mower runs on Wi-Fi and Bluetooth, and anti-theft tracking needs the separate Access+ 4G module, per the specifications. Trusted Reviews notes the module includes a first year of data, with a yearly fee after that.
How noisy is it for neighbours?
Quiet. Segway quotes 58dB(A), per the specifications. Top Ten Reviews measured about 60 decibels, like a subdued conversation, and Trusted Reviews heard just a gentle buzz while it cut.
Compare with
i2 AWD
Its replacement: same app and cut, with a third driven wheel for slopes and no aerial to put up.
Edges still need a strimmer, and 4G data is paid after the first year.
E15 Robot Lawn Mower
Finds its way by camera alone, so there's no aerial and it's one of the quickest mowers to set up.
Testers with bumpy or damp grass had it slipping and getting stuck.
YUKA mini 2 1000
Laser guidance lets it navigate under trees and through narrow gaps without satellite help.
It struggled on a steep test slope and can leave a strip along raised edges.
