Segway Navimow i105N Review: The Cheapest Wire-Free Mower That Owners Actually Keep

Most robot mowers that cost under $1,000 still want a boundary wire. The i105N does not. It uses RTK satellite positioning plus a front camera, which is the same arrangement Segway sells in its $2,500 X series, cut down to a 7 inch deck and a 55 Wh battery. Does it work? Yes. Consumer Reports, Android Police, Reviewed, and a few hundred Amazon and Reddit owners agree on that. The question is whether your yard is the kind of yard it works in. This review sorts that out. We have not run one ourselves. Every performance claim here is tied to a tester or an owner.

What it is

The i105N is the smallest mower in Navimow’s US line and has been since 2024. The N means North American SKU; Europe gets the i105E. It is rated for 1/8 acre, about 500 square meters or 5,400 square feet, and Navimow sells it alongside the i110N (1/4 acre, bigger battery) on the same platform. Both are front wheel drive. Both have a manual height dial.

In 2026 Segway added two newer small mowers above it. The i2 AWD (i206, 0.15 acre, $999; i210, 0.25 acre, $1,299) adds a third driven wheel and a 45 percent slope rating. The i215 LiDAR (0.37 acre, $1,329 on sale) swaps RTK for a LiDAR tower and ships with a low cutting kit that goes down to 0.8 inches. Neither replaced it. It is still the cheapest wire-free mower Segway sells, and the only one at this price from a brand with a US dealer channel. Navimow’s store listed it at $799 in October 2026 and showed it sold out. Amazon, Home Depot, and Lowe’s carry it.

The hardware has not changed since launch. Firmware has. Owners on Reddit and Amazon describe the mapping and edge behavior improving over the first few months as the mower refines its boundary, and one Amazon reviewer collected by Paul’s Lawn Mower Reviews said that after almost three months the mower had visibly improved “its cutting boundaries.”

Specs that matter

From our mower database, built from Navimow’s US spec page on October 17, 2026, cross checked against the Consumer Reports model page.

Three rows decide the fit. The 60 minute runtime means it mows about half its rated area per charge. One Reddit owner with a 300 square meter zone (about 3,200 square feet) reports it “has to charge” partway through, which is normal for the rating and annoying if you expected one pass. The 2.0 inch minimum cut rules it out for Bermuda or zoysia owners who want a putting green look. No lowering kit exists for the i Series. The low cutting kit Navimow sells is for the i2 LiDAR and H2 platform, which is why those go to 0.8 inches and the i105N does not. And 30 percent slope is gentle. Call it 3 feet of drop over 10 feet of run. Our lawn size guide has the full conversion table.

What owners report

The owner record on this mower is longer than on anything else Navimow sells, because it has been out two full seasons. The pattern is consistent across r/automower, r/SegwayNavimow, and the Amazon reviews that Paul’s Lawn Mower Reviews collected.

The praise comes in three flavors. Setup is easier than people expect. The r/automower poster “placed the antenna and connected everything up, expecting to having to relocate and adjust afterwards. But it all just worked out of the box.” The app is good. Zones, no-go areas, per zone schedules. Android Police singled it out too. And it does the job on the right lawn: “Freed up so much of my time, and the yard looks great,” and one owner recovering from back surgery, no longer able to push a mower, said it solved that problem. On slopes, one owner with a hill says “the mower handles the hill just fine with stock wheels as long as the ground is dry.”

The complaints are almost all one complaint: satellite signal under trees. The i105N is RTK plus a camera, with no LiDAR, so when the sky closes over it has little to fall back on. The camera helps it hold a boundary for a stretch, as Android Police noted, but it does not navigate by camera alone. Owners say so every season. One warned “Make sure that your yard has good signal throughout all seasons,” because once the trees leafed out “the quality of the GPS signal started to decline, and the robot started to get lost.” Another spent two hours mapping and lost the whole perimeter under a silver maple. Another “took 2hrs to find a location that would work good enough for GPS signal.” A few bought the antenna extension kit and the 4G module and still could not get a stable fix. On r/SegwayNavimow, an i105 owner reports the mower losing GPS while sitting in its own charging station. Think of RTK as a GPS that also listens to a fixed antenna in your yard, like a second witness. If neither witness can see the sky, the mower stops. Our RTK signal fixes page is the first thing to read if that sounds like your yard, and our navigation explainer covers what LiDAR and vision-only mowers do differently.

The second complaint is traction. It is a 24 pound front wheel drive mower with smooth tires. On damp ground or soft spots, owners report it getting stuck and “digging a rut trying to get itself out,” and one says it “will get stuck on a literal flat surface regardless of what wheels you use.” Navimow sells off-road wheels for $99.99, and owners report mixed results with them. If your yard has a mushy corner, make it a no-go zone rather than hoping the wheels fix it.

Third, and minor: the height dial is manual, so every zone gets the same cut, and the on-mower control panel is clunky. Both Android Police and owners mention it.

What the published tests found

Consumer Reports lab tested the i105N as part of its robotic mower program, which scores cutting performance (standard, damp, tall, uneven, and sloped lawn), convenience, noise, instructions, build quality, and safety. The overall score is behind the paywall. Quartz, summarizing CR’s rankings in September 2026, reports CR “rated it strong across every cutting test, including damp grass, slopes, uneven ground and a standard lawn,” and lists it at $799 for a yard “no more than roughly an eighth of an acre.” That is the headline.

Android Police gave it 7.5 out of 10 in August 2024, when it cost $1,000. It liked the value, the camera assisted RTK, the obstacle detection, and the cut quality it saw. Two dislikes. The control panel, and no Alexa or Google Assistant. The one real performance knock: navigation lines. “Although its positioning is flawless, the robot doesn’t always follow parallel lines,” leaving “small unmowed strips of grass that require manual trimming,” and it “struggles when mowing corners.” The reviewer also flagged the 60 minute battery and suggested the i110N for anything bigger than a small lawn.

Reviewed keeps the i105N in its tested best-of list as the sub-$1,000 value entry, at a $999.99 MSRP with an RTK pole. MowerBotLab, a spec based site, notes that 9to5Toys tracked the i105N at $669 against its $799 price repeatedly during 2026, which matches the deal coverage we have seen. The $669 price is real.

Put together: the lab says it cuts well, the tester says it navigates well but leaves strips at the edges, and two seasons of owners say the deciding factor is the sky over your grass.

FCC status

The i105N was on sale in the US in 2024 and 2025, so it was authorized for US sale before the FCC’s July 28, 2026 Covered List took effect. Our database marks it authorized before the list. The list stops new foreign made robotic devices from getting authorized without a conditional approval; it does not affect a model already approved and on shelves, and firmware updates are allowed through at least January 1, 2029 per the FCC’s guidance. In practical terms, this is one of the lower risk small mowers to buy right now. The newer i2 AWD and i215 LiDAR launched in 2026 and we could not verify their status. Our FCC tracker has the full list.

Price history and when to buy

The i105N launched at $999 in 2024, which is the price Android Police reviewed it at. By 2025 Navimow’s own store had it at $799, and $799 is the price Consumer Reports and Navimow both show in 2026. The real street price has been lower. 9to5Toys tracked $669 more than once between spring and summer 2026, and our keyword research logged a $669 to $799 range across retailers. Navimow’s site showed it sold out in mid October 2026 at $799. Prices here are as of October 17, 2026 and are fall sale prices.

The buy rule is simple. At $669 it is the best deal in wire-free mowing for a small yard. At $799 it is still fair. At $999 it is not, because the i206 AWD is $999 and climbs 45 percent slopes. Fall and the spring pre-season (March) have been the discount windows.

Budget for the Garage S ($199.99) if the dock sits in the open, and for the antenna extension kit ($49.99) if your best open-sky spot is a roofline rather than a stake in the lawn. Skip the Access+ 4G module unless you need to control the mower away from home Wi-Fi.

Alternatives

Navimow i206 AWD, $999. Same brand and app, 0.15 acre, three driven wheels, 45 percent slope rating, built-in 4G with a year of Connect+. If your small yard has a hill or a soft patch, the $200 step up fixes the traction complaint. Launched 2026, FCC status unverified. Our under $1,000 roundup compares them.

Navimow i110N, $1,099 on Navimow’s store. Same mower with double the battery and a quarter acre rating. If you are at 5,000 square feet and growing, or you want the whole lawn done in one run, this is the one Android Police pointed to.

eufy E15. Camera only. No antenna at all. That sidesteps the RTK problem. Bob Vila’s tested roundup lists it as best bang for the buck. The trade is a one map per dock limit and no RTK precision. See our wire-free roundup for the trade.

FAQ

How big a yard can the i105N handle?

Navimow rates it at 1/8 acre, about 5,400 square feet. Measure grass, not lot. Owners report it keeping up with that over a week of scheduled mowing, with one or two charge stops per session.

Does it work under trees?

Under a few trees at the edge, usually. Under a canopy that covers the lawn, no. This is the one complaint that shows up every season, and it is why the Navimow i215 LiDAR and the Mammotion LUBA mini 2 exist.

Can it cut lower than 2 inches?

No. The dial runs 2.0 to 3.6 inches and there is no lowering kit for the i Series. The i2 LiDAR and H2 ship with a low cutting kit that goes to 0.8 inches.

Does it need the 4G module?

No. Wi-Fi and Bluetooth are built in. The $119.99 Access+ module adds cellular for control when you are away from home or your Wi-Fi does not reach the lawn.

Is it still legal to buy after the FCC rule?

Yes. It was authorized before the July 2026 Covered List, so it can be sold, used, and updated. See the tracker.
