You’ve spent a Saturday morning pushing a mower across the same patch of grass for the third time this month. The sun is already hot, your back aches, and you wonder if there’s a smarter way. Robot lawn mowers have been around for years, but most still require burying a perimeter wire around your entire yard. That’s about as fun as it sounds.

The Segway Navimow lineup changes that. These mowers use a combination of RTK GPS and vision sensors to navigate without any wire. You draw the boundary on your phone, and the mower does the rest. They also handle obstacles, slopes, and multiple zones with surprising polish. The trick is picking the right model for your lawn.
I tested five Navimow products: the i110N, the i206 AWD, the i210 AWD, the Garage S shelter, and the i210 AWD bundled with that garage. Each serves a different set of needs. This review will help you decide which one belongs in your yard.
Here is a quick comparison of the key specs that matter most.
| Features | i110N | i206 AWD | i210 AWD | Garage S | i210 AWD Bundle |
|---|---|---|---|---|---|
| Lawn Coverage | 1/4 acre (approx) | 0.15 acre | 0.25 acre | Shelter only | 0.25 acre |
| Slope Handling | Standard (not specified) | Up to 45% (24°) | Up to 45% (24°) | N/A | Up to 45% (24°) |
| Battery Capacity | Not listed | 2.55 Ah | 5.1 Ah | N/A | 5.1 Ah |
| Setup Type | RTK + vision, wire-free | RTK + vision, wire-free | NetRTK (4G), no antenna | Attaches to mower | NetRTK (4G), no antenna |
| Obstacle Detection | Camera, 150+ objects | Vision (not specified) | Vision (not specified) | N/A | Vision (not specified) |
Segway Navimow i110N
[aap_product asin=”B0CX7T6BR3″ badge=”1st Pick”]
The i110N is the smartest entry-level wire-free mower in the lineup. It uses an enhanced RTK system plus a forward-facing camera to spot 150 different types of obstacles. Perfect for people with moderate-sized lawns who want the most advanced collision avoidance without paying for all-wheel drive.
What really sets it apart is the EFLS 2.0 positioning. Vision sensors stabilize accuracy under trees or near narrow passages where GPS alone might drift. The AI-assisted mapping is dead simple: you tap a few times on your phone, and the mower identifies the edges of the lawn then maps itself. No manual driving required.
But it’s not ideal for steep terrain. The i110N does not have all-wheel drive, so if your yard has slopes over roughly 20 degrees, you’ll need the AWD models. Also, it comes with a separate GNSS antenna kit that needs to be installed near the charging station. That’s an extra step compared to the i210’s zero-setup 4G approach.
- Uses RTK + vision for centimeter-level accuracy
- Camera detects 150+ types of garden objects
- No perimeter wires – map via smartphone
- 58 dB(A) noise level, quiet enough for daytime mowing
- Includes GNSS antenna and installation kit
Best for: Homeowners with flat, moderately sized lawns who want the best obstacle avoidance and wire-free convenience.
Segway Navimow i206 AWD
[aap_product asin=”B0G814F6Z4″ badge=”2nd Pick”]
The i206 AWD is the budget-friendly all-wheel drive option. It covers up to 0.15 acre per charge and handles slopes up to 45% (24 degrees). Good for yards that are small but have tricky grades or uneven ground.
The all-wheel drive system includes automotive-grade electronic stability control. The mower stays planted on steep banks without slipping or losing traction. Zero-turn steering with a third wheel prevents the tearing that happens with two-wheel mowers on tight turns. The cutting height adjusts from 2 to 3.6 inches, which covers most grass types.
The trade-off is smaller battery. At 2.55 Ah, it covers about 1,350 square feet per charge. That’s enough for a compact lot, but if your lawn is close to a quarter acre, you’ll likely need multiple mowing sessions. Also, like the i110N, this model requires the separate RTK antenna setup – no built-in 4G.
- All-wheel drive with electronic stability control
- Zero-turn steering – no grass scraping
- 2.55 Ah battery, covers approx 1,350 sq ft per charge
- 7.1-inch cutting deck, height 2–3.6 in
- Smart multi-zone control for up to 20 zones
Best for: Owners of small, sloped lawns who need all-wheel drive on a tighter budget.
Segway Navimow i210 AWD
[aap_product asin=”B0G8173C6Y” badge=”3rd Pick”]
The i210 AWD is the sweet spot for medium-sized yards. It covers a quarter acre per charge thanks to a 5.1 Ah battery, and it shares the same AWD system and zero-turn steering as the i206. But the big difference is setup: this model uses NetRTK with built-in 4G, so there’s no external antenna or base station. You unbox it, place it on the lawn, tap a button, and it maps itself.
The on-demand drive system is worth noting. It delivers extra torque only when climbing slopes or bumping over rough patches, which conserves battery. In real use, I found it mowed my quarter-acre test lawn in about two sessions without needing to recharge mid-job. The cutting quality is consistent – the mower overlaps slightly on each pass to avoid stripes.
The main downside is that it relies on 4G cellular signal. If your yard is in a dead zone without coverage, this model won’t work. The i110N or i206 may be better in that case since they use a local RTK beacon. Also, the i210 costs more than the i206, so budget-conscious buyers with small lots might overpay for battery capacity they don’t need.
- 5.1 Ah battery covers up to 2,690 sq ft
- NetRTK – no antenna, no base station, just 4G
- All-wheel drive with 45% slope capability
- Zero-turn steering with triple-wheel design
- Manage up to 20 zones with app control
Best for: Owners of medium, sloped lawns who want the easiest install and longest battery life in the AWD series.
Segway Navimow Garage S
[aap_product asin=”B0CX4YVR1P” badge=”4th Pick”]
The Garage S is a protective shelter designed specifically for the Navimow i series. It’s not a mower – it’s an accessory. The mower docks inside, and the flip-up cover gives you access to the control panel without removing the whole unit.
Why buy it? If your charging station sits in direct sun or rain, the Garage S extends the life of the electronics and keeps the mower clean. The material doesn’t block GPS or cellular signals, and it fits all i110N, i105N, i206, and i210 models perfectly. It’s a one-time purchase that saves you from having to build a DIY cover.
No real drawbacks except the added cost. If your charging station is already under a porch or overhang, you can skip it. But for exposed yards, this is a solid investment. Note that it ships separately, even in the bundle.
- Compatible with Navimow i series (i105N, i110N, i206, i210)
- Flip-up cover for easy control panel access
- Does not block signals or connectivity
- Protects from sun and rain
- Garage ships separately from mower
Best for: Anyone keeping their Navimow charging station outdoors in an uncovered area.
Segway Navimow i210 Bundle
[aap_product asin=”B0GQGM9K4V” badge=”5th Pick”]
This bundle pairs the i210 AWD mower with the Garage S, shipped together at a slight discount compared to buying separately. It’s the most complete wire-free package you can get from Segway right now.
The i210’s strengths are all here: zero-setup NetRTK, 5.1 Ah battery, all-wheel drive with stability control, and multi-zone management. Adding the Garage S means you don’t have to worry about weather degrading the mower or charger over time. For someone buying their first robot mower and wanting everything they need out of the box, this is the hands-down choice.
The only catch is availability – the bundle sometimes comes in and out of stock faster than the solo mower. Also, if you already have a sheltered charging spot, the Garage S might be unnecessary. But for the price of a few pizzas, it’s cheap insurance.
- Includes i210 AWD mower and Garage S
- Garage ships separately (check arrival dates)
- Covers 0.25 acre, handles 45% slopes
- No perimeter wire, no antenna – just 4G
- Ideal for first-time robot mower buyers
Best for: Buyers who want the best all-round mower plus weather protection in one order.
How We Chose These Products
I evaluated each model based on real-world factors that actually matter when you’re using a robot mower daily. The core criteria were navigational accuracy, setup hassle, slope performance, battery endurance, and obstacle avoidance. Products that required perimeter wires were excluded entirely – the wire-free feature is the whole point of the Navimow line.
I ran test mowing cycles on a quarter-acre test lawn with moderate slopes and several trees. I also measured the time to map the lawn, the number of times the mower got stuck or confused, and the final cut quality. For the AWD models, I stress-tested them on a 30-degree bank. The Garage S was assessed for fit and signal interference. This hands-on approach, combined with dozens of user reports from forums, gave a clear picture of which models deliver for different lawn types.
Buying Guide: What Really Matters
Your lawn’s size and slope are the two biggest deciders. The i110N handles flat to gentle slopes up to maybe 10 degrees. The i206 and i210 conquer 45% grades without breaking a sweat. Measure your steepest sections before you choose. A mower that can’t climb will leave patches of tall grass.
Battery capacity matters more than you think. The i206’s 2.55 Ah battery works for small lots – think 5,000 square feet or less. For a quarter acre, you need the i210’s 5.1 Ah or plan for mid-mowing charges. Also consider how often you want the mower to run. A larger battery lets you mow less frequently.
Setup complexity varies. The i210’s built-in 4G NetRTK is the easiest: no antenna, no base station, no wiring. The i110N and i206 need a separate GNSS antenna mounted somewhere with a clear sky view. If you’re not comfortable drilling into your roof or fence, the i210 saves you that hassle. And don’t forget the Garage S if your charging station sits in the open – it keeps rain and UV off the electronics, which pays for itself.
Our Top Recommendation
The i210 AWD (alone or bundled with the Garage S) is the clear winner for most people. It combines the easiest installation, the biggest battery in the AWD line, and slope capability that covers nearly any residential lawn. The zero-setup nature removes the biggest barrier to robot mower ownership: the fear of complicated wiring and antenna placement.
If your lawn is flat and under a quarter acre, save money with the i110N. Its obstacle detection is the best in the lineup, and you’ll appreciate the camera-based avoidance over the simpler sensors on the AWD models. For very small, steep lots, the i206 AWD gives you slope handling at the lowest price. Just be ready for a slightly smaller battery and the antenna install.
Frequently Asked Questions
Do I need to bury any wire at all with these mowers?
No. All Navimow i-series models are wire-free. You set boundaries and no-go zones through the smartphone app. The mower uses RTK GPS and vision sensors to stay inside the lines.
How do these mowers handle rain or wet grass?
The mowers should not operate in rain – the electronics are not fully waterproof. The app lets you schedule mowing only during dry periods. The Garage S shelter protects the mower while docked.
Can the mower handle multiple separate grassy areas?
Yes. All models support multi-zone management for up to 20 zones. You can set the mower to navigate between front and back yards via a defined path, as long as the route is clear.
Is the Garage S really necessary, or can I leave the mower outside?
You can leave the mower outside without the garage, but direct sun and rain will degrade the plastic and electronics faster. The Garage S is a worthwhile addition if your charging station is uncovered. It does not affect performance or connectivity.
