Segway Navimow H2 Review 2026: H210 vs H220, and Why the $400 Step-Up Is the Better Buy

Quick Answer: The Segway Navimow H2 is Navimow’s most complete navigation package for small and mid-size lawns. It combines LiDAR, network RTK and a camera, so it needs no boundary wire, no antenna and keeps working under trees and at night. It comes in two sizes: the H210 ($1,799, about 0.25 acre) and the H220 ($2,199, about 0.5 acre). Per Navimow’s own H2 manual, the H220 has twice the battery (216 Wh vs 110 Wh) and mows about 2.6 times more lawn per charge, so for most buyers the $400 step-up is the better value. On a quarter-acre lawn that is mostly shaded, the cheaper i215 LiDAR ($1,599) already does the job.

Navimow now sells three navigation approaches at the small-yard end of its US lineup. The i2 AWD uses network RTK plus vision. The i215 LiDAR uses LiDAR plus vision and no satellites at all. The H2 stacks all three, which Navimow calls EFLS (LiDAR + NRTK + Vision). The idea is simple. RTK satellite positioning is precise on open lawns but loses its fix under tree canopy and between houses. LiDAR measures distances to fences, walls and trees, so it works in shade and in total darkness, but has less to lock onto in a wide, featureless lawn. The H2 switches between the two, and Navimow says the switch takes 20 milliseconds.

All the specs below come from the Navimow H2 series user manual (North American edition, downloaded from Navimow’s support page on October 31, 2026) and navimow.com’s US product pages, unless we say otherwise.

Segway Navimow H210 vs H220 specs

Segway Navimow H220: the size most buyers should get

H210 vs H220: what the extra $400 buys

Navimow’s two H2 models are the same mower with different batteries. That makes the comparison unusually clean. Here is how the two stack up on the numbers that decide how well a robot mower keeps up with your grass. Per-charge area, daily capacity and price per acre are our own calculations from the manual’s runtime, charge-time and area-per-hour figures.

The H220 mows faster as well as longer. The manual rates it at 2,637 sq ft per hour against 2,045 for the H210, so it does more per minute even though both share the same 8.66 in cutting deck. Navimow’s footnotes say its “0.93 acre per day” and “2x faster charging and cutting than the previous generation” claims are based on the H220, not the H210.

The H210 only makes sense in one situation: a lawn that is clearly under a quarter acre, where you want the H2’s combined navigation and don’t need the extra battery. Even then, the H220 finishes the same quarter-acre lawn faster. Per our math, a full pass of 0.25 acre (10,890 sq ft) takes the H210 about 2.9 charges and roughly 7.7 hours of clock time. The H220 does it on one charge plus a top-up in about 6.1 hours.

Real coverage: how long a full pass takes

Robot mower lawn ratings describe the biggest lawn the mower can keep up with on a schedule, not what it cuts in one go. The table below shows best-case clock time for one complete pass, assuming dry, evenly cut grass and the manual’s figures. Wet or long grass, narrow zones and slopes all lower the real number, and the manual itself says the mower covers more per hour on open areas than on small, separated lawns.

That is the strongest argument for the H220. At its full rated size, a complete pass fits inside half a day. The i215 LiDAR, by comparison, needs about 3.5 charges and close to 16 hours for a full pass at its 0.37-acre rating, per our i215 LiDAR review. If you mow every day or two, the bigger battery means the schedule never falls behind after a rainy week.

EFLS navigation: where LiDAR + RTK + vision earns its price

The H2’s selling point is that you don’t have to choose between the two navigation systems that split the wire-free market. Navimow’s product page lays out the division of labor: LiDAR under trees and at night, network RTK on open terrain, and vision for obstacle recognition. The solid-state LiDAR scans about 200,000 points per second with a 230 ft range, according to Navimow, and has no exposed rotating parts.

That matters most on a common suburban layout: an open front lawn plus a back yard with mature trees, a narrow side passage and a fence line. An RTK-only mower like the i2 AWD can drift or stall under the canopy. A LiDAR-only mower like the i215 can struggle on the open, featureless front lawn. The H2 is built for exactly that mix. If your lawn is all open sky or all shade, a single-system mower costs less and does the job. Our LiDAR robot lawn mower guide and GPS robot mower guide explain the trade-off in detail.

Two things to check before you buy:

• Network RTK coverage. The antenna-free RTK layer depends on Navimow’s correction network reaching your address. Navimow has a ZIP-code coverage checker on its H2 page. Where coverage isn’t available, you lose the open-lawn half of the system.
• No antenna fallback. Unlike Navimow’s older H1 series, the H2 does not take an external RTK antenna. Where network RTK isn’t available, it runs on LiDAR and vision alone, which is still fine for most fenced yards with trees and beds.
• The 4G service. Network RTK and remote monitoring run over the mower’s built-in 4G connection. The manual’s settings page shows a separate “expiration date for 4G service”, and Navimow’s product page says Connect+ is free for one year and then renews at $32.90 a year. Our 4G connectivity guide explains what that subscription covers.

The fine print

• “Up to 3 years” warranty means 2 years on the battery. The North American warranty table in the manual gives the H210 and H220 mowers 3 years, but battery packs and power adapters only 2 years, and blades aren’t covered at all. The clock starts on the later of the purchase date or first activation, which helps if the mower sits boxed until spring.
• 25% at the edges. The 45% (24°) slope rating applies inside the working area. At the boundary the manual limits it to 25%, so a steep bank that runs right up to a fence or drop-off should sit inside the map with a margin. Navimow also measured the 45% figure on dry grass cut to 1.97 inches. For steep lawns, see our robot mower for hills guide.
• The 60 dB(A) figure is measured without the blades cutting. Navimow’s footnote says the noise level was measured “without cutting” with the drive motor at 0.7 m/s. The manual’s EN 50636-2-107 declaration lists 60 dB(A) sound power and 52 dB(A) sound pressure, each with a 3 dB(A) uncertainty.
• 2-inch edge gap. Navimow says the H2 cuts as close as 2 inches to walls and fences and can ride one wheel onto flush borders. Vertical edges still leave a strip for a string trimmer. Our edge-cutting comparison covers how other brands handle it.
• Plan for 39-inch passages, not 2.3 ft. The product page says the H2 navigates paths as narrow as 2.3 ft, but Navimow’s support FAQ asks for channels at least 100 cm (39 in) wide and 40 cm high. Use the larger figure for gates and side passages; see our robot mower gate guide.
• Small, flat objects can be missed. Navimow’s support FAQ says objects narrower than 1 cm aren’t detected, despite the 0.4 in marketing figure. Frandroid’s H210 ran over a 10 × 4 cm stone and a flat wood block, and Notebookcheck’s H206 drove over a low-contrast tennis ball. Pick up the lawn before a run.
• Rear-wheel drive only. Frandroid found the treaded rear wheels clogged on wet soil and left marks in tight turns. For wet or steep lawns, an AWD mower is safer.

What independent testers found

No major US outlet had published a hands-on H2 review by October 31, 2026. The tests so far come from Europe, where Navimow sells the H206, H210, H215 and H230. The H210 there is the same size class as the US H210, but no tester has reviewed the US-only H220. Here is what they found:

The pattern is consistent. LiDAR navigation under trees works as promised, and the H2 is quiet. The weak spots are the same ones most wire-free mowers share: an uncut strip along walls, auto-mapping that sometimes needs a manual fallback (Navimow’s firmware 4.1.0 in March 2026 added more auto-mapping modes), and traction on wet ground. Meilleure Innovation’s runtime and charging figures fell short of Navimow’s, while Androidmag’s matched them, so plan around the manual’s numbers with some margin.

Navimow H2 vs the alternatives

Prices are from each maker’s US store, checked October 30–31, 2026. Price per rated acre is our calculation from the maker’s headline rating.

The closest rival is the Mammotion Luba mini 2 AWD, which also combines network RTK, LiDAR and cameras, adds all-wheel drive, and costs the same as the H210 at its current $1,799 sale price on Mammotion’s US store. All-wheel drive makes it the better pick for steep or wet slopes. The H220 wins on rated area for the money: half an acre for $2,199. If your lawn is bigger than half an acre and mostly open, the Navimow X330 covers a full acre for only $100 more than the H220. Its RTK-plus-vision system is weaker under heavy tree cover.

Navimow H2 by the numbers

• $400 for 2.6x the lawn per charge: the H220 costs 22% more than the H210 but carries 96% more battery energy (216 vs 110 Wh) and covers about 2.6 times more grass per charge, per the manual’s runtime and area-per-hour figures.
• 0.93 acre per day: Navimow’s 24-hour coverage claim for the H220, calculated as 24 hours ÷ (mowing time + charging time) × area per charge. Our own math from the manual lands at about 0.94 acre. That is nearly double the H220’s 0.5-acre rating, which leaves headroom for slopes and wet weeks.
• 20 ms: how fast Navimow says the H2 switches between LiDAR and RTK positioning.
• 2 years: the warranty on the H2’s battery pack and power adapter, against 3 years on the mower itself, per the North American limited warranty.
• $32.90 a year: the Connect+ 4G renewal after the free first year, per navimow.com.
• No discount since launch: Wayback Machine snapshots of navimow.com from March to October 2026 show the H210 at $1,799 and the H220 at $2,199 with no sale price. US sales started in mid-February 2026, after the CES 2026 announcement.

Who should buy the Navimow H2 (and who shouldn’t)

Buy the H220 if your lawn is between a quarter and half an acre and mixes open grass with trees, buildings or narrow side passages. That is the layout where an RTK-only or LiDAR-only mower has a weak spot and the H2’s combined system pays off. It is also the better-value H2 for almost any lawn above 0.15 acre.

Buy the H210 only if your lawn is well under a quarter acre and you specifically want the triple navigation stack and a rain sensor.

Skip the H2 if your lawn is all open sky (the i210 AWD does the same job for $500–$900 less), all shade and under 0.37 acre (the i215 LiDAR is $200 less than the H210 and covers more), steep or often wet (the AWD Luba mini 2 climbs better), or bigger than half an acre (look at the X3 series or our half-acre guide). Also check network RTK coverage for your ZIP code first, because the antenna-free promise depends on it.

The bottom line

The Segway Navimow H2 is the Navimow to buy when your lawn won’t commit to one navigation system: open in front, shaded in back, with a tight side passage in between. Its LiDAR + network RTK + vision setup removes the weak spot of each single system, and it adds a rain sensor, Apple Find My tracking and a 3-year mower warranty (2 years on the battery). Between the two sizes, the H220 at $2,199 is the clear pick. It doubles the battery, mows about 2.6 times more lawn per charge and costs 39% less per rated acre than the H210.
