Segway Navimow i110 Review: i Series and X3 Compared

The Segway Navimow i110 is the entry point into Segway’s wire-free robot mower lineup for a yard bigger than a small strip of grass. It is priced at $1,099 and maps up to 0.25 acre, sitting one step above the smaller i105 and several steps below the X3 Series machines built for half an acre and up. If your lawn is a quarter acre or smaller, your slopes stay under 30% (17 degrees), and you want to skip burying a perimeter wire, the i110 is the model in this lineup to buy. If your yard runs past a third of an acre, skip ahead to the Navimow X330 in the alternatives section below.

This is a researched review built from Segway’s own product page, its support articles, and its published warranty policy. Nobody on staff ran this unit through a season on a real lawn. See how we score for the method behind the numbers below.

Design and setup

The i110 weighs 24 lbs and measures 21.4 x 15.1 x 11.2 in, small enough to carry in one trip from the box to the lawn. Setup runs through the Navimow app: you walk the mower’s boundary once (or draw it on the map), and the mower relies on Segway’s EFLS 2.0 system, a hybrid of GNSS positioning and a forward-facing camera, to hold the line. There is no perimeter wire to bury and, where Segway’s Network RTK coverage reaches your address, no local antenna to mount either. Segway states that RTK access and the cellular data behind it are included at no extra cost in covered areas. Outside that coverage, an antenna kit ships or sells separately.

Cutting width is 7.1 in, on the narrow side for the price, and cutting height adjusts manually from 2.0 to 3.6 in, with the app letting you set a different height per mapped zone. Segway’s own FAQ notes the i110’s recommended area is 0.25 acre, with mapped area able to stretch to roughly 1.2 times that in favorable, low-complexity yards, so call it 0.3 acre at the outside edge before performance likely suffers.

How it scores

Navigation and setup: wire-free installation and antenna-free RTK in covered areas are the i110’s strongest features. A phone-guided map is faster to set up than burying wire, and EFLS 2.0 is built specifically to keep the mower inside the line when satellite signal drops in tree cover or near a house.

Cutting and coverage: a 0.25-acre recommended area at $1,099 is modest for the price versus the rest of the category, and the 7.1 in cutting width means more passes to finish a lawn near that ceiling. The mower climbs slopes up to 30% (17 degrees) but is only rated for 10% (6 degrees) right at the boundary edge, so a steep border strip is the one place this machine is more likely to struggle.

Weather and safety: the i110 carries an IP66 rating, so it is sealed against dust and heavy rain, and Segway’s VisionFence system uses a 140-degree RGB camera to recognize more than 150 objects across pets, tools, and everyday yard items. Animal Friendly Mode detects pets and wildlife within 5 meters and keeps a 1-meter buffer. Anti-theft alerts, however, require the separate Navimow Access+ 4G module, so out of the box there is no cellular alert if the mower is lifted or moved.

App and controls: the Navimow app handles scheduling, multi-zone mowing plans, and live status over Bluetooth or Wi-Fi, and the mower works with Alexa and Google Home. Remote monitoring away from your home network needs that same optional 4G module, an added cost worth knowing about before you decide you don’t need it.

3-year cost: at $1,099 up front for a quarter-acre machine, the i110 costs more per acre of coverage than either the smaller i105 or, on a per-acre basis, the larger X3 models. Segway’s own support article states blades should normally be replaced after 80 working hours, and the mower is not cheap to keep fed with parts once you factor that in. See the math below.

The Practical Math

Segway’s warranty policy covers the i110 mower for 3 years and its battery pack and power adapter for 2 years, but it explicitly excludes blades as a consumable item. Its support article for the i Series states blades should normally be replaced after 80 working hours of use, checked through Settings, Mower, Maintenance and Tools, Part Maintenance in the app. Segway sells a Blade Assembly Plus pack for $23.99 that includes 12 blades and 15 bolts and is compatible with the i1 Series, which covers both the i105 and i110.

Assuming a typical 0.25-acre lawn mowed on a schedule through a roughly seven-month season lands close to one 80-hour blade cycle per year, a reasonable owner should budget about one pack a year:

• Navimow i110 mower: $1,099.00
• Blade Assembly Plus (12 blades): $23.99 x 1 pack/yr x 3 yrs, based on Segway’s 80-working-hour blade replacement guidance = $71.97

That puts a 3-year total near $1,170.97 for the mower and its documented consumable. Segway does not publish the charging station’s power draw, so we are not estimating an electricity line here rather than guess at a number. An optional Garage S shelter runs $199.99 and the 4G Navimow Access+ module is a separate purchase on top of that if you want remote alerts and anti-theft coverage; neither is required for the mower to work as sold, so neither is counted in the total above.

Alternatives

Navimow i105, $799.00. This is the i110’s smaller sibling and shares the same EFLS 2.0 navigation, VisionFence detection, 30% (17 degree) max slope rating, 58 dB(A) noise level, and IP66 sealing. The only real differences are a smaller 0.125-acre recommended area, a shorter 60-minute full-charge mowing time versus the i110’s 120 minutes, and the $300 lower price. It is the better buy for a small front lawn or a single mapped zone under an eighth of an acre.

Navimow X330, $2,299.00. Segway’s X3 Series steps up to a 1.0-acre recommended area on the X330, with the X350 ($2,799.00) covering 1.5 acres and the X390 ($4,499.00) covering 2.5 acres. These are the right call once a yard outgrows the i Series, at roughly double the i110’s price for four times the coverage.

Who should skip it

Skip the i110 if your lawn is meaningfully larger than 0.25 acre, since Segway’s own guidance caps comfortable mapped area around 0.3 acre before layout complexity starts working against the mower. Skip it too if your property has a boundary that runs steeper than 10% (6 degrees), since that is the edge-specific slope limit rather than the higher 30% (17 degree) figure used for open cutting. Buyers who want built-in anti-theft alerts without an extra purchase, or who need to cover more than half an acre, are better served by an X3 Series model instead.

FAQ

How much does the Segway Navimow i110 cost?

Segway lists the i110 at $1,099.00 on its official store, covering the mower itself with no perimeter wire or base station included in that price for RTK-covered areas.

Do I need to bury a wire for the Navimow i110?

No. The i110 uses Segway’s EFLS 2.0 system, which combines GNSS positioning with camera-based vision, so setup is done by mapping the yard through the app rather than installing a physical perimeter wire.

How often do the blades need to be replaced?

Segway’s support documentation states blades should normally be replaced after 80 working hours of use, and blades are explicitly excluded from the mower’s warranty as a consumable part.

What is the difference between the i105 and the i110?

Both share the same navigation, safety, and app features. The i105 is rated for a 0.125-acre lawn and costs $799.00, while the i110 covers 0.25 acre and costs $1,099.00, with a longer full-charge mowing time of 120 minutes versus 60 minutes on the i105.

Does the Navimow i110 include theft protection?

Not by default. Cellular anti-theft alerts and remote monitoring require Segway’s separate Navimow Access+ 4G module, which is sold as an add-on accessory rather than included with the mower.
