Segway Navimow i105N Review
The Cheapest Robot Mower Worth Buying
The Segway Navimow i105N is a wire free robot mower for 1/8 acre lawns at $669.00, with 400 ratings behind it and reviews going back to 2024. Owners with open, flat lawns rate it well, and the recurring complaint is that it struggles around trampoline legs, swing sets and shallow dips.
The verdict
Segway sells the Navimow i105N as the entry point to wire free robot mowing, and at $669.00 the pricing works. Every other machine in our ten costs more, most of them twice as much.
What makes the i105N worth a close look is not the price on its own. Carrying 400 ratings at 4.1 stars, with reviews stretching back to 2024, it has the longest owner record of any robot mower we found. Robot mowers are new enough that most listings offer a few months of evidence. Here there are owners reporting on a second and third season.
What 1/8 acre actually means
Segway rates the i105N for 0.125 acres, about 5,400 sq ft, cut 7.1 inches at a time. Small, in other words, and the price reflects it.
Mowing happens in sessions. The mower works, returns to its dock when the battery runs low, charges, then goes back out and carries on until the lawn is done. Owners who understand that pattern are happy with it. Owners expecting one unattended pass like a push mower are the ones who sound disappointed.
At 24 lbs the mower is genuinely light. Carrying it to a front lawn or lifting it over a step is a one person job, which is not true of the 54 lb machines further up this page.
Open lawns good, cluttered lawns bad
The clearest pattern in the reviews splits on what is sitting on the grass.
Chelsea reviewed the i105N in August 2024 and came back in November 2025 to cut her rating to three stars. Her verdict after more than a year is specific and worth quoting plainly: wide open yards get a pretty good job, and trampoline legs or swing sets are beyond it. She says the mower will not get close to them.
Sean Curry, in June 2024 with an August 2024 update, names the other weak spot. The i105N digs its nose into shallow divots and strands itself. He bought the heavier wheels Segway sells, found they helped some but did not solve it, then came up with a simple fix of his own. Four stars, and he still recommends it.
Setup splits owners down the middle
Two owners describe the same process in opposite terms. An owner called Scott, in October, calls it easy to set up and use. Ryan, posting as Tools, Trails & Kitchen on 21 June 2026, gave it one star for what he called painfully difficult setup and frustrating support, while praising the concept and the hardware.
Both can be true. RTK navigation needs the base antenna to see enough sky, and how much sky your lawn offers is not something the listing can tell you. Plan for an afternoon, and buy somewhere the mower can go back if the signal does not hold.
An owner called G. Clark reports great customer support, so the support experience is not uniformly poor either.
Running costs and the 4G question
No subscription is required. The listing offers a 4G module for anti theft tracking as an optional add on, and nothing about mowing, mapping or the app depends on buying it. Worth saying because the question comes up constantly and the big roundups do not answer it.
Who should buy it
Owners of small, flat, fairly open lawns who want to find out whether robot mowing suits them without spending $1,800. On that lawn the i105N does the job and the price makes the experiment cheap.
Anyone with play equipment, heavy tree cover or an uneven surface should spend more. The Mammotion LUBA mini 2 navigates by LiDAR and cameras rather than satellite, and owners report far fewer navigation problems, though it costs $1,799.00.

Questions people ask
Does the Navimow i105N need a subscription?
No. The only extra cost named on the listing is a 4G module for anti theft tracking, described as an optional add on. Mowing, mapping and app control do not depend on it.
Why is it cheaper than every other robot mower here?
Coverage. The i105N is rated for 1/8 acre, roughly 5,400 sq ft, which is the smallest area in our ten. Cutting width is 7.1 inches, also the narrowest.
Does it get stuck?
In shallow dips, yes. Sean Curry, writing in June 2024 and updating in August 2024, describes the mower digging its nose in and stranding itself in shallow divots. He tried the heavier wheels Segway sells, found they helped some but not enough, and worked out his own fix.
How well does it handle obstacles?
Not well. Chelsea first reviewed in August 2024 and cut her rating to three stars in a November 2025 update, saying the mower does a pretty good job in wide open yards but will not get close to trampoline legs or swing sets.
Is setup difficult?
For some owners, very. Ryan, posting as Tools, Trails & Kitchen on 21 June 2026, rated it one star over what he called painfully difficult setup and frustrating support, while an owner called Scott on the same listing describes it as easy to set up and use. Plan for an afternoon and check the return window.
