The Segway Navimow i105N mows lawns of up to 1/8 acre without a perimeter wire, finding its way with RTK satellite positioning and camera vision. It sits in the Entry tier, and Segway rates it for 1 hour of mowing per charge. An IP66 rating keeps dust out completely and guards it against strong water jets.
Who It's For
Lawn size is the first thing to check, because Segway rates the Navimow i105N for up to 1/8 acre. Within that limit, it suits a medium-sized suburban lawn that is level or only gently sloped. Laying a perimeter wire does not appeal to you, and you are comfortable drawing the lawn's edges and setting the mowing schedule in an app. Ideally, most of the grass is open to the sky, since satellite positioning is most reliable with a clear view overhead.
Look Elsewhere If
You may want a different mower if your lawn is larger than 1/8 acre. The Sunseeker X3 Plus, one tier up, shares this model's navigation, camera-based obstacle detection and slope rating, and is rated for a larger lawn. A steep yard is another reason to look further. Segway rates this mower for slopes of up to 30%, and the Sunseeker V3 and Ecovacs Goat O1000 are rated for steeper ground. If tall trees shade much of your lawn, a mower that does not rely on satellite signals may suit it better.
Where To Buy
Key Features
Navigation And Boundary Setup. The Navimow i105N locates itself with RTK, which is satellite positioning corrected by a reference station, together with camera vision that reads the lawn. The lawn's boundary is drawn in the app rather than marked with a wire, and the mower follows systematic rows across the grass. Because RTK depends on satellite signals, it is most dependable where trees and buildings leave the sky open.
Battery And Charging. The battery holds 2,550 mAh, and Segway rates the Navimow i105N for 1 hour of mowing on a full charge. Refilling the battery takes 1.5 hours, so the mower spends more time charging than mowing. Segway does not say how much lawn one charge covers, so leave room in the schedule for charging if your lawn is close to the 1/8 acre rating.
Slopes. Segway rates the Navimow i105N for slopes of up to 30%. Slope percent describes the rise of the ground over its level distance, a different measure from an angle in degrees. On a flat or gently sloping lawn, this limit is unlikely to matter, but measure the grade of any steep bank before you buy.
Obstacle Detection And Sensors. The Navimow i105N watches for obstacles with AI Vision, a camera designed to recognize objects in its path. Segway lists no second sensor, such as LiDAR, alongside it. The mower has a tilt sensor as a safety feature. Segway does not publish how reliably the camera recognizes objects, so clearing toys and hoses from the grass before each session still makes sense.
Cutting Height And Width. The cutting height can be set from 2 to 3.6 inches, so the Navimow i105N suits a lawn kept at a moderate height better than a very short one. Each pass cuts a strip 7.1 inches wide, narrower than the Ecovacs Goat O1000, so covering the lawn takes more passes. On a lawn of this size, that matters less than it would on a large property.

How It Compares
Sunseeker X3 Plus Check Price on Amazon
Sunseeker X3 Plus sits one tier up and shares this mower's navigation and slope rating. Sunseeker rates it for up to 3/10 acre, a larger lawn than this model's rating. Its 5,000 mAh battery recharges in 1.5 hours, the same time as this model needs, though Sunseeker gives no runtime. It cuts from 1.6 to 3.2 inches. Choose it if your lawn is too big for the Navimow i105N.
Sunseeker V3 Check Price on Amazon
Sunseeker V3 is in the same tier and rated for a slightly larger lawn, up to 1/6 acre. It navigates with camera vision alone and does not use RTK satellite positioning. Sunseeker rates it for slopes of up to 42%, which makes it the better fit for a yard with steeper banks. Its IPX5 rating covers water jets and says nothing about dust. Sunseeker gives no runtime, and a full recharge takes 1.6 hours.
Ecovacs Goat O1000 Check Price on Amazon
Ecovacs Goat O1000, another Entry tier option, is rated for a larger lawn than this model. Ecovacs also rates it for steeper slopes, up to 45%. Ecovacs pairs its camera with LiDAR, which uses laser light to measure distance, for spotting obstacles. Consider it if you keep your grass short, since it cuts from 1.2 to 3.1 inches, or if you want a second obstacle sensor.
Worth Knowing
Segway does not say whether an RTK reference station or antenna is part of the package, so confirm what comes in the box before you buy. Nor does it list the weight, the warranty or support for separate mowing zones. The mower carries a rain sensor and an IP66 rating, but Segway does not state whether it mows in wet weather or what it does when rain starts. Segway puts its noise level at 58 dB, and the lower that figure, the quieter the mower. Whether the app talks to the mower over Wi-Fi, Bluetooth or a cellular network is also left unstated.
Frequently Asked Questions
Does the Navimow i105N need a boundary wire?
No. The boundary is virtual, so you draw it in the app, and the mower tracks its position using RTK satellite positioning and camera vision.
How big a lawn can it mow?
Up to 1/8 acre, according to Segway. For a bigger lawn, the Sunseeker X3 Plus is rated for up to 3/10 acre.
How steep a slope can it handle?
Up to 30%. That is Segway's rated maximum. The Sunseeker V3 is rated for up to 42% and the Ecovacs Goat O1000 for up to 45%.
How long does it mow on one charge?
Up to 1 hour, according to Segway. Its 2,550 mAh battery then needs 1.5 hours to recharge.
Does it mow in the rain?
Segway does not say. It has a rain sensor and an IP66 rating, but Segway does not explain how the mower responds once rain begins.
How loud is it?
Segway rates it at 58 dB. The Ecovacs Goat O1000 is rated slightly quieter, at 57 dB, while the Sunseeker V3 is rated quieter still, at 55 dB. The X3 Plus is quieter again, at 52 dB.
What cutting heights does it offer?
From 2 to 3.6 inches. If you prefer a shorter lawn, the Ecovacs Goat O1000 cuts as low as 1.2 inches.
Do I need the app?
Yes. The app is where you draw the boundary and plan when the mower goes out.
