Segway Navimow X315

The X315 is the entry to Segway's X3 line: the same 43 lb chassis, 9.3 in cutting deck, 2 to 4 inch height range and EFLS 3.0 positioning as the $4,499 X390, just with a 6Ah battery good for about two hours and a half-acre rating. EFLS 3.0 fuses RTK with three cameras doing visual SLAM and odometry, which is why testers at Notebookcheck and TechRadar found it kept mowing straight under trees where RTK-only mowers stall. Obstacle avoidance uses a 300-degree camera array with a ToF sensor and recognizes 200+ objects including pets, with night vision so it can run after dark at 60 dB. Setup is about 30 minutes and truly wire-free, though you still mount an RTK antenna. Segway has pulled it from its own store (listed at $1,999 but unavailable) while Home Depot, Acme Tools and Abt still sell it, and it is the only X3 that does not get multiple years of 4G included - one year, then about $33 a year. Reviewers' knocks: it is two-wheel drive so the 50% slope rating is optimistic on side-hills, there is no onboard rain sensor (it relies on forecasts), the single 9.3 in disc leaves about 3.5 in uncut at edges without the optional Trimmer accessory, and standby power draw is high. Versus the Mammotion Yuka at $1,399 the X315 costs more but is faster and better under trees; if you are near 0.5 acre, the X330 is often only $300 more.

How it navigates

EFLS 3.0: RTK GNSS fused with three cameras running visual SLAM and inertial odometry, so it holds position under trees. Included RTK antenna needs open sky; perimeter is mapped by driving it in the app.

Highlights

6Ah battery: 120 min runtime, about 60 min charge

Pros

  • ✓Same chassis, cameras and cut quality as the flagship X390 for less than half the price
  • ✓RTK fused with visual SLAM keeps working under tree canopy
  • ✓Fast recharge: about 30 minutes gives roughly 90 minutes of mowing
  • ✓200+ object recognition with night vision makes after-dark runs practical
  • ✓Cut height goes to 4 inches, unlike the older H series

Cons

  • ✗Two-wheel drive; the 50% slope rating does not hold on side-hill runs
  • ✗No physical rain sensor, only weather-forecast pausing
  • ✗Leaves a few inches uncut along walls unless you add the Trimmer accessory
  • ✗Only one year of 4G included versus two to five on the bigger X3 models
  • ✗Pulled from Segway's own store; retailer stock only

Pros and cons above are drawn from the manufacturer’s spec sheet and published reviews; this model is too new for a body of owner reports.

Owner Insightssummarized from owner forums and retailer reviews

The X315 is the entry to Segway's X3 line: the same 43 pound chassis, 9.3 inch deck, 2 to 4 inch height range and three-camera EFLS 3.0 positioning as the flagship X390, with a 6Ah battery for about two hours and a half-acre rating. The X315 was the model the most detailed lab test ran, and its verdict matches owners of the larger versions: impressive navigation, near-perfect obstacle avoidance, quiet running, and one nagging flaw in edge coverage that the optional Trimmer is meant to solve.

Setup is a 30-minute job and mapping on a flat lawn is mostly automatic. Positioning is the X3 family's strength: testers report straight rows under trees and no wandering, with the caveat that the antenna still needs sky and that moving it means remapping. The cut is even and the direction alternates between sessions, but every X3 leaves about 4 inches at walls. The app is clear, 4G is built in, charging takes about an hour, and noise is low enough for night runs. The weak points are two-wheel drive on side-slopes, strandings on roots until islands are mapped, forecast-only rain handling, and an overcautious camera on bare ground.


Buy the X315 for a half-acre lot that is mostly open, flat to gently rolling, with edges that are beds or sidewalks rather than walls. At $1,999 list it is the expensive way to buy a small mower - the Mammotion Yuka is around $1,399 and the Ecovacs Goat A1600 RTK and Dreame A2 undercut it further - and it is also slightly slower and gets only one year of 4G versus three or five on its siblings, so owners near the half-acre line usually step up to the X330 for a few hundred dollars more. Deal-breakers: side-hill slopes, lots of walls and fences you expect it to edge, or a budget that the Yuka already satisfies.

What owners like

  • +Setup is the easiest in its class: testers of the X315 and its siblings had it mapped and mowing in about 30 minutes, the pieces snap together in only one orientation, and AI-assisted mapping traces edges on its own on flat, open lawns.
  • +EFLS 3.0 keeps its line under trees. Testers of the X315 report a stable fix and dead-straight rows on lawns with scattered obstacles, and testers of the X350 call it confident and accurate under canopy where single-sensor mowers stall.
  • +Obstacle detection is close to flawless day or night. The X315 tester's hedgehog dummies, garden hoses and stray objects were all dodged; the only miss was a tennis ball on one of three tries.
  • +Fast for a single-disc mower: the X315 covered more than 4,000 square feet in two hours on normal mode before docking at 15 percent, and the X350 and X390 are quicker still.
  • +Charging is quick, about an hour from empty on the X315's 6Ah pack, so a half-acre lawn gets done in a morning rather than over two days like the H series.
  • +Quiet at roughly 55 dB in testing; owners across the X3 line run it after dark without disturbing anyone.
  • +The app is clean and logical with live progress mapping, and the dot-matrix face on the mower shows status at a glance; 4G is built in with a year of service before a roughly $33 renewal.
  • +Blade changes are simple, and owners across the line praise Segway support for instant, useful answers and a 3-year warranty.

Common complaints

  • −Edges are the big letdown on every X3. The 9.3 inch disc sits about 3.5 inches inside the body and cannot move, so even perfect edge tracking leaves roughly 4 inches uncut at walls and fences; the X315 tester called it a missed opportunity on a mower sold on edge mowing.
  • −The Trimmer accessory that is supposed to fix that was unavailable in the X315 tester's market at review time, costs extra, and testers of the X350 found its auto-trim mode hangs up on rocks and its manual mode needs you walking behind holding a button.
  • −Two-wheel drive. Testers could not get the X315 to demonstrate its 50 percent slope claim on a ramp, and X350 testers report the front end sliding downhill when it crosses a slope sideways; AI-assisted mapping also stranded a tester's X350 on a steep bank.
  • −Gets hung up on exposed tree roots and partially buried obstacles until you draw off-limit islands around them; owners of the X350 describe a few weeks of stuck notifications before the map was tuned.
  • −No physical rain sensor. The X350 kept mowing through a thunderstorm in one test because it relies on forecast data, which testers called a disappointment at this price.
  • −VisionFence can be overcautious: it pauses to look around, keeps wide buffers early on, and had to be switched off over bare dirt patches in early spring; one owner of the X350 complains it demands VisionFence and beeps continuously.
  • −Move the antenna or dock and you remap from scratch, which catches owners at winter storage. The app also lacks some wanted options such as disabling obstacle avoidance along edges.
  • −Power hungry and pricey for a half acre: the X315 tester measured roughly 14 kWh a month for a 5,400 square foot lawn cut three times a week plus 18 Wh a day on standby, and noted the Mammotion Yuka, Ecovacs Goat A1600 RTK and Dreame A2 cost far less.

Common Questions

Does the X315 cut to the edge?
No. The disc is inset about 3.5 inches from the body on every X3, so testers measured roughly 4 inches of grass left along walls and fences even when the mower tracked the edge perfectly. Edges next to beds or pavement at grade come out much closer. The optional Trimmer accessory is meant to close the gap but adds cost.
Is the X315 fast enough for half an acre?
Yes, comfortably. The X315 tester saw more than 4,000 square feet in two hours before it docked, and the battery refills in about an hour, so a half acre is a morning's work. It is slightly slower than the X350 and X390 but far quicker than the i series.
How does it handle slopes?
Straight up and down, fine; sideways, not well. The X315 tester could not get it to prove the 50 percent claim on a ramp, and testers of the X350 report the front sliding downhill on side-hills because it is two-wheel drive. Owners with real hills point to an AWD Mammotion Luba instead.
Does it work under trees?
Yes, this is what the X3 line does better than most. RTK is fused with three cameras and odometry, and testers report it holding straight rows under canopy. The antenna itself still wants open sky, and some owners on heavily shaded plots report occasional satellite hunting.
Does it have a rain sensor?
Not a physical one. It uses forecast data, and one X350 test saw it keep mowing through a thunderstorm. It is IP66 rated so the rain does not hurt it, but wet-lawn mowing is on you to schedule around.
X315 or X330?
Same machine apart from the battery and 4G term. The X330 adds about 40 minutes of runtime, a one-acre rating and a longer bundled 4G plan for a few hundred dollars more, so owners near half an acre or with any expansion plans usually go X330.

Segway Navimow X330
~$2,299
RTK + Vision

The X330 is the X3 model most people should look at: a one-acre rating, 8Ah battery for about 160 minutes of mowing with a 65 minute recharge, and it sits at $2,299 on Segway's site after a $500 cut from launch pricing. Like the rest of the X3 line it runs EFLS 3.0 - RTK fused with three cameras doing visual SLAM - so it holds position under tree canopy where the older H series and most budget RTK mowers lose lock, and its 300-degree camera plus ToF array recognizes 200+ obstacles with night vision. It mows fast (about 3.3 ft/s) in tidy parallel stripes, cuts 2 to 4 inches, runs at 60 dB, and includes two years of 4G with GPS tracking before the roughly $33 a year Connect+ renewal. Pro Tool Reviews and Robot Review Desk both call the X3 the most polished wire-free mower for flat-to-moderate suburban lots. Where it falls short: two-wheel drive makes the 50% slope rating shaky on side-hills, there is no physical rain sensor (it relies on forecasts), the centered 9.3 in disc leaves a few inches uncut along walls unless you buy the Trimmer accessory, and 43.7 lb is a lot to lift over a curb. Against the Mammotion Luba 2 AWD 3000, the X330 is quicker and gentler on turf but the Luba climbs 80% grades. For a one-acre yard with trees and gentle slopes, this is the sweet spot of the range.

Segway Navimow X4
from ~$2,499
RTK + Vision

The X4 is the mower Segway built to answer the Luba: four hub motors with dual suspension, an 84% (40 degree) slope rating, and a 17 in dual-disc deck driven by two 180 W motors, all on a 64 lb body that can step over 2.8 in obstacles. It comes as the X430 (1 acre, 10.2Ah, $2,499) and the X450 (1.5 acres, 12.8Ah, $2,999), both charging in about 90 minutes at 224 W. The big change from the X3 series is that positioning uses tri-frequency Network RTK delivered over the built-in 4G, so most yards need no antenna at all, and the front wheels steer independently so it turns like a car instead of pivoting and scuffing turf. How-To Geek gave it an Editor's Choice after a season: auto mapping finished a backyard in ten minutes, EdgeSense cut within 2 in of fences, and it ran quietly at night, but the dock still had to be moved twice to find sky, the first pass looked choppy until a second run, and it drove up onto a raised patio and scuffed the coating. 9to5Toys found it handled soggy, uneven ground but chewed turf when wet and missed dog waste hidden in tall grass. Against the Mammotion Luba 3 AWD 3000 at $2,109 the X430 costs more and rates 4% less slope, but cuts an inch wider, goes down to 0.75 in for warm-season turf, and its Ackermann steering is gentler on grass.

Segway Navimow i2 AWD
from ~$999
RTK + Vision

The i2 AWD replaces the i105N and i110N with the same 7.1 in single-disc body but three fixes for the old model's main complaints: a third, on-demand drive motor on the front zero-turn wheel with knobby off-road tires, a 4G module built in instead of the $120 Access+ add-on, and Network RTK that removes the antenna from setup where coverage exists. Slope rating rises from 30% to 45%, and Segway says the rear motor only engages when traction is needed, which stretches runtime by up to 30%. The i206 AWD ($999) carries a 2.55Ah pack for about an hour of mowing and a 0.15 acre rating; the i210 AWD ($1,299) doubles that to 5.1Ah, roughly two hours, and a quarter acre, and both recharge in about the same time they run. The cutting hardware is unchanged: 2 to 3.6 in height on a manual knob, a narrow deck, and no edge mode. Mowing Magic found the zero-turn wheel stopped the turf scuffing that plagued the i1 and rated the 59 dB noise as conversation-level, but confirmed the manual height knob and the uncut wall strip. Compared with the leftover i110N at $929 you pay a little more for real traction, built-in 4G and antenna-free setup; compared with the i215 LiDAR at $1,599 you give up LiDAR positioning under heavy tree canopy and the wider 8.6 in deck.

Segway Navimow i110N
~$929
RTK + Vision

The i110N is the same 7.1 in body as the i105N with double the battery (5.1Ah, about 120 minutes per charge) so it can cover a quarter acre, and it won Tom's Guide's Editor's Choice for cut consistency at a price that has slid from $1,299 at launch to a $929 list and frequent sub-$800 sales. It uses Segway's EFLS 2.0 RTK plus a front VisionFence camera, so when the satellite fix wobbles under trees it can hold the boundary visually for a while instead of wandering off. Reviewers consistently praise the straight, overlapping stripes with no missed patches and the near-silent 58 dB operation that makes night mowing realistic. The complaints are the flip side of the budget price: it is slow (Tom's Guide clocked roughly three times the time of push mowing), the 30% slope rating and front-wheel drive mean it spins out on real hills, PCWorld's unit repeatedly drove off curbs because there is no drop-off detection, and GPS anti-theft needs the $120 Access+ 4G module. Segway has pulled it from its own store in favor of the i210 AWD, but Home Depot still stocks it. For a flat quarter-acre suburban lot it remains one of the cheapest dependable wire-free options; if your yard has slopes or a parking strip, look at the i210 AWD or a Luba Mini instead.

Segway Navimow X350
~$2,799
RTK + Vision

The X350 buys you battery, not a different mower: it shares the X330's 43.7 lb chassis, 9.3 in cut, 2 to 4 inch height range, EFLS 3.0 RTK-plus-vision positioning and 300-degree camera array, but carries a 10Ah pack for about 200 minutes per charge (80 minute recharge) and a 1.5 acre rating. Segway lists it at $2,799, down from $3,499 at launch, and it includes three years of 4G before the roughly $33 a year renewal. Residential Tech Today beta-tested this exact model for a season and found the standout traits were quiet 60 dB running that allowed night mowing, reliable obstacle recognition, and confident navigation on a tree-heavy lawn - RTK antenna placement still mattered, and moving it meant remapping. Early-spring patches of thin grass confused the VisionFence boundary logic until it was toggled off, and the optional Trimmer accessory occasionally hung up on rocks. As with all X3 mowers it is two-wheel drive, so the 50% slope rating assumes straight up-and-down runs, and there is no onboard rain sensor. Compared with a Husqvarna Automower 450X at roughly $4,000 installed, the X350 is a DIY afternoon and about a third cheaper; compared with the Mammotion Luba 2 AWD 5000 it gives up AWD hill-climbing for faster, straighter cutting. Best for 1 to 1.5 acres of mostly open, gently rolling lawn.

Segway Navimow i105N
~$799
RTK + Vision

The i105N is the mower that made wire-free RTK cheap. Segway cut it from $999 to $799 in 2026 and it regularly dips to $669-699, which puts it in Worx Landroid Vision territory while still using a proper RTK antenna for centimeter-level positioning. It is small - 7.1 in cutting width, 24 lb, a 2.55Ah battery good for about an hour - so the rated 1/8 acre is honest; Amazon owners with a typical city lot say a full cut takes around 2.5 hours across two or three charge cycles. Setup is genuinely DIY: mount the antenna somewhere with open sky, drive the mower around the perimeter with your phone, and let AI Assist Mapping snap to the lawn edges. Owners like the quiet 58 dB motor, the straight-line stripes, and that it pays for itself in a season versus a lawn service. The knocks are consistent too: getting stuck on flat ground and in dips, mapping frustration when trees hang over the antenna, a manual cutting-height dial, and a few units dying after a few months with slow email-only support. The 30% slope limit and front-wheel drive rule out anything hilly. Compared with the Mammotion Yuka Mini, the i105N is cheaper and simpler but has no vision-only mode when RTK is hopeless; step up to the i110N if you have more than about 5,000 sq ft.
