Segway Navimow Review 2026: i Series, X3 & Which One to Buy

Quick Answer: The Segway Navimow is the wire-free robot mower to buy when you want RTK accuracy without Husqvarna prices. The cheapest model, the i105, is $799 on navimow.com (November 4, 2026) for about 0.125 acre, and the all-wheel-drive i206 AWD and i210 AWD start at $999 for up to a quarter-acre. Every current Navimow is wire-free, and Segway rates its EFLS positioning to about 2 cm, so you never bury a boundary wire. For large or obstacle-heavy yards, step up to the camera-equipped Navimow X3, $2,299 to $4,499 for 1 to 2.5 acres. The catch: RTK needs a reasonably clear view of the sky, and the i105 is rated to just 30% (17°); for steep banks a Mammotion Luba 3 AWD (80% / 38.6°) is the better tool. Updated November 4, 2026: the i105 is back at its $799 list price (this page listed it at $669 in July and October), the $1,999 X315 is no longer listed on navimow.com, so the X3 line now starts at $2,299, and both X4 models are sold out.

Segway turned the Navimow into one of the most cross-shopped robot mowers of 2026 by hitting the price point wire-free RTK never used to reach. Husqvarna’s cheapest EPOS model, the Automower 410 iQ, lists at $2,599.99 on husqvarna.com (November 4, 2026). The Navimow i105 brings centimeter-accurate, no-wire mowing for $799, under a third of that. Below is our full review: the lineup, how EFLS navigation actually works, where the Navimow shines, where it doesn’t, and exactly which model fits your yard.

Segway Navimow at a glance

The Segway Navimow lineup in 2026

Segway’s two core Navimow families are the affordable wire-free i Series and the larger, camera-equipped X3 line, the 2026 i2 LiDAR adds an antenna-free option in between, and the H2 combines LiDAR with network RTK for mixed shade-and-open lawns.

• Navimow i1 and i2 AWD (i105 / i206 AWD / i210 AWD) — the volume sellers and the value sweet spot. The i105 ($799) is rated for 0.125 acre and 30% (17°). The all-wheel-drive i206 AWD ($999, 0.15 acre) and i210 AWD ($1,299, 0.25 acre) climb 45% (24°) and fuse tri-frequency network RTK with vision, with no antenna, per navimow.com. Best for typical suburban front-or-back lawns where you want no wire and no fuss; our wire-free robot mower guide covers the category. The older i108 and i110N are no longer listed on navimow.com US; see our Navimow i110N review if you find one at a retailer, and our i2 AWD review for the current models.
• Navimow X3 series — the premium, big-yard line. It keeps EFLS RTK but adds VisionFence, an AI camera that recognizes and steers around obstacles (pets, toys, furniture) and helps the mower hold its position where the sky view is partly blocked. Navimow lists the X330 (1.0 acre) at $2,299, the X350 (1.5 acres) at $2,799 and the X390 (2.5 acres) at $4,499, making it a contender in our best robot mower for large yards rankings.
• Navimow i2 LiDAR (i215 LiDAR) — the antenna-free Navimow. It swaps RTK for solid-state LiDAR plus a camera, so there’s no wire and no antenna mast. It’s rated for 0.37 acre and 45% (24°) and listed at $1,599 on navimow.com (November 4, 2026). This is the Navimow to pick when trees or buildings block the sky over a small lawn. The catch is rear-wheel drive; see our Navimow i215 LiDAR review.
• Navimow H2 (H210 / H220) — the Navimow that combines all three systems: LiDAR, network RTK and vision, with no wire and no antenna. The H210 is rated for 0.25 acre at $1,799 and the H220 for 0.5 acre at $2,199 on navimow.com (October 31, 2026). Per Navimow’s manual, the H220 carries twice the battery (216 vs 110 Wh) and mows about 2.6 times more lawn per charge, so it’s the better-value size. Pick the H2 when one lawn mixes open sky with heavy shade; see our Navimow H2 review.
• Navimow X4 (X430 / X450) — all-wheel drive with dual suspension, rated to 84% (40°), at $2,499 (1.0 acre) and $2,999 (1.5 acres). Both were sold out on navimow.com on November 4, 2026.

One accessory matters for fenced yards: every current Navimow except the old H1 series works with the $449.99 MowGate, a self-opening fence gate that lets one mower cover a front and back yard (also sold out as of November 4, 2026).

For a flat-to-rolling quarter-acre, the i210 AWD or i215 LiDAR is the one to buy; only step up to the X3 if your yard is large, obstacle-heavy, or partly shaded by trees.

Live Navimow price ladder (verified November 4, 2026)

Every figure below came from navimow.com’s US store on November 4, 2026. Do not shop this brand from search snippets: the i105 has been listed at $999, $799 and $669 at different points, and the X330 is widely quoted at $2,799, which is actually the X350’s price.

Three things this table makes obvious. First, the i105 at $799 is still the cheapest Navimow, but the i206 AWD costs only $200 more and adds all-wheel drive and a 45% (24°) slope rating. Second, the X4 series changes the slope calculus, once it is back in stock: the X430 covers the same 1.0 acre as the X330 for $200 more but is rated to 84% (40°) versus 50%, putting it in Mammotion Luba AWD territory. If you have banks, the extra $200 is the easiest upgrade on this page. Need more than 1 acre with that same slope rating, the X450 is hardware-identical to the X430 — the $500 premium buys coverage headroom only, not different components. Third, the X3 line now starts at $2,299: the $1,999 X315 that headed this table in July is no longer listed on navimow.com US. And note the i105’s real slope rating is 30% (17°), lower than the 45% of the i2 models. Size the mower to your steepest ground, not your flattest.

One naming trap worth knowing: Segway’s own site calls it the i105, but some retailer listings title it “i105N”. They are the same mower — don’t pay a premium hunting for a nonexistent variant. See our full i105N review for the coverage, slope, and price breakdown.

How Navimow navigation works (EFLS RTK)

The thing that sells a Navimow is that there is no wire. Segway’s EFLS (Exact Fusion Locating System) is an RTK setup: a small fixed reference antenna corrects the satellite signal in real time, tightening positioning to about 2 cm — versus the several-meter error of plain GPS. That precision is what lets you draw a virtual boundary by walking the lawn edge once, then edit no-go zones around flower beds on your phone in seconds.

The trade-off is the same for every RTK mower: it needs a reasonably clear view of the sky. Dense tree canopy or a tight, building-shaded yard can weaken the fix and make the mower pause or drift. That is exactly why the X3 adds a camera — and why, for heavily wooded lots, a vision/LiDAR mower like the Mammotion Yuka can be a safer bet. For the full breakdown of how satellite navigation compares, see our GPS robot lawn mower guide.

What the Segway Navimow does well

Like all robot mowers, the Navimow is also extraordinarily cheap to run: a typical robot mower draws only about 0.5–1 kWh per cutting session and roughly $10–$25 of electricity a year, far less than a gas mower’s fuel and upkeep. That low draw is part of why wire-free RTK bots feature so heavily in our best robot lawn mower pillar.

Where the Segway Navimow falls short

• Slopes. The i105 is rated to 30% (17°), the i2 and H2 to 45% (24°) and the X3 to about 50% (27°), per Segway — fine for rolling lawns, wrong for steep banks. Only the X4 (84% / 40°, sold out in November 2026) is built for them. For grades beyond that you want all-wheel drive like the Mammotion Luba 3 AWD (80% / 38.6°) or another robot mower for hills.
• Tree cover. RTK needs sky visibility. Heavily wooded or building-shaded yards can cause pauses or drift — a vision/LiDAR mower handles canopy better.
• Obstacle avoidance on the cheapest model. The i105 has a camera (VisionFence), but Navimow rates only its H2 and X4 for 200+ object types. If pets and toys live on your lawn, look at the H2, X3 or X4.

Segway Navimow vs the alternatives

The takeaway: the Navimow i Series wins on wire-free RTK per dollar. Spend up to the X3 for acreage or obstacle avoidance, to the Mammotion Luba 3 AWD for steep slopes, or to a Husqvarna Automower for long-haul reliability. If burying wire doesn’t bother you, the wired Worx Landroid is cheaper still, though the $799 i105 now sits inside the Landroid’s roughly $700–$1,100 range; see our full Navimow vs Landroid breakdown.

Segway Navimow by the numbers

• ~2 cm positioning accuracy: Segway rates its EFLS RTK system to roughly 2 cm — tight enough to hold a crisp virtual boundary with no wire, versus the several-meter error of plain GPS.
• 30–45% (17–24°) max slope (i Series): Per Segway, the i105 handles 30% and the i2 models 45% — short of the 80% (38.6°) an all-wheel-drive Mammotion Luba 3 AWD is rated for, which is why slope is the Navimow’s hard limit.
• ~$10–$25/year to run: A robot mower like the Navimow uses only about 0.5–1 kWh per session and roughly $10–$25 of electricity a year — a fraction of the fuel, oil, and tune-up cost of a gas mower.

The bottom line

The Segway Navimow is the smart-money wire-free robot mower for a flat-to-rolling suburban lawn. The i105 brings centimeter-accurate, no-wire mowing for $799, under a third of Husqvarna’s cheapest EPOS model, and the i206 AWD adds all-wheel drive for $200 more. Built-in anti-theft tracking is a nice touch. Step up to the camera-equipped X3 only if your yard is large, obstacle-heavy, or partly shaded. For steep banks or fully off-road terrain, cross-shop the Mammotion Luba 3 AWD — Mammotion has dropped the full-size Luba 2 AWD from its US store — and the rest of our best robot lawn mower rankings, or read our full Navimow vs Luba, Navimow vs Ecovacs Goat, and Navimow vs Husqvarna head-to-heads. Last updated November 4, 2026: re-checked every price against navimow.com’s US store (i105 $669 to $799, X315 delisted, X4 sold out, i2 AWD, i215 LiDAR and H2 added to the price table), corrected the claim that the i Series has no camera-based obstacle avoidance, and removed the H1 series as the quietest pick because it is sold out. Noise-sensitive? The i105 is rated at 58 dB(A) per navimow.com, and our quietest robot lawn mower rankings compare manufacturer dB(A) ratings across brands. And if you landed here after searching a cordless brand you already own, read why there is no RYOBI robot mower — the $799 i105 is the answer to that search. If you were actually searching for STIGA’s RTK-based A-series, the Navimow is the closest US-buyable match in the same wire-free RTK category. Cross-shopping Honda’s dealer-only Miimo?
