The catch
Segway Navimow i105N
With a one-eighth-acre rating, there is little room for a lawn that is oversized or rapidly growing.
Side by side
Segway Navimow i105N vs eufy Robot Lawn Mower E15: E15 covers more grass and needs no RTK antenna, while i105N suits taller cuts
Quick verdict
A smaller high-cut lawn suits i105N. More rated area and a camera-based setup with no RTK antenna suit eufy E15.
Before you buy
Why, and what it costs you
A 0.16-acre lawn is more than i105N's rating covers
It goes 0.035 acre past i105N and sits 0.04 acre under E15's rating.
Where this comes from
0.160 - 0.125 = 0.035 acre, and 0.200 - 0.160 = 0.040 acre.
The catch
eufy Robot Lawn Mower E15
It navigates by vision alone, so borders must be clear and the light adequate.

Pick the situations that sound like you
A 0.16-acre lawn is more than i105N's rating covers
It goes 0.035 acre past i105N and sits 0.04 acre under E15's rating. 0.160 - 0.125 = 0.035 acre. 0.200 - 0.160 = 0.040 acre.

- Depends
An 18-degree limit on E15 is about 32.5% grade
Normalized, the difference from i105N's 30% is only about 2.5 percentage points. That is a small terrain distinction and not an AWD-class jump. Grade percent = tan(18 degrees) × 100 = 32.49%. 32.49 - 30 = 2.49 percentage points.

Within this pair, a 3.5-inch cut points to i105N
E15's 3-inch maximum is half an inch short, whereas the desired height stays within i105N's 2-3.6-inch range. 3.5 - 3 = 0.5 inch. Range endpoints are what is compared here, and available adjustment steps still have to be checked.

The installation approach of one model matches your preferred setup
The i105N's 2-3.6-inch range reaches taller grass settings, and E15 covers 1-3 inches. Camera-based navigation spares E15 a separate RTK antenna, but its performance still depends on the visual scene, boundaries and operating conditions.

In practice
Differences you will notice
A 0.16-acre lawn is more than i105N's rating covers
It goes 0.035 acre past i105N and sits 0.04 acre under E15's rating.
How we worked this out
0.160 - 0.125 = 0.035 acre, and 0.200 - 0.160 = 0.040 acre.
An 18-degree limit on E15 is about 32.5% grade
Once normalized, the gap from i105N's 30% is only about 2.5 percentage points. It is a small terrain distinction and not an AWD-class jump.
How we worked this out
Grade percent = tan(18 degrees) × 100 = 32.49%, and 32.49 - 30 = 2.49 percentage points.
Within this pair, a 3.5-inch cut points to i105N
E15's 3-inch maximum is half an inch short, while i105N's 2-3.6-inch range still includes the desired height.
How we worked this out
3.5 - 3 = 0.5 inch. Range endpoints are what this compares, and available adjustment steps still need checking.
Option A
Segway, i105N
Navimow i105N
An eighth-acre lawn gets virtual boundaries and camera-assisted obstacle detection from this smaller Navimow i Series model.
- Best for
- Compact suburban lawns, if keeping setup simple and wire-free matters to you
Facts we checked
- The i105N is rated by Segway for 0.125 acre.
- A cutting range of 2.0 to 3.6 inches is published.
- On the i Series, RTK positioning is paired with camera-based obstacle recognition.
Option B
eufy, E15
Robot Lawn Mower E15
Cameras lead the way on this mower, which maps with no wire, RTK antenna or LiDAR hardware, so setup on a simple small lawn is unusually clean.
- Best for
- Small lawns with clear borders, for owners who want as little mapping hardware as possible
Facts we checked
- eufy's rating for the E15 covers lawns up to 0.2 acre.
- Cameras handle its navigation, with no boundary wire or RTK antenna needed.
- After automatic lawn mapping, the mower plans parallel routes.
Spec by spec
Where they really differ
| Spec | Segway Navimow i105N | eufy Robot Lawn Mower E15 | In practice |
|---|---|---|---|
| Rated grass area | 0.125 acre | 0.2 acre | One eighth acre is what the i105N is sized for, and E15 is rated for one fifth acre. So they suit different lawn sizes before navigation even comes into it. Measure the grass alone, leaving out the house, paving and beds, instead of using the lot area. |
| Cutting-height range | 2-3.6 inches | 1-3 inches | Your chosen height has to fall inside the range of the exact US model. The minimum height of H variants can differ from that of a larger standard model. |
| Positioning and installation | RTK and vision with a reference antenna | Camera-based navigation, no RTK station | The i105N's 2-3.6-inch range reaches taller grass settings, and E15 covers 1-3 inches. Camera-based navigation spares E15 a separate RTK antenna, but its performance still depends on the visual scene, boundaries and operating conditions. |
| Drive and interior climbing limit | Two-wheel drive, 30% grade | Two-wheel drive, 18 degrees, about 32.5% grade | Work from a measured rise-over-run grade. A maximum interior climbing rating does not establish the allowable slope beside a boundary, pond or drop. |
| Combined cutting width | 7.1 inches | 8 inches | Cutting width is the grass swath. It says nothing about body width or a guaranteed gate clearance. The real work rate comes down to turns, overlap and charging. |
Trade-offs
What each pick costs you
With Segway Navimow i105N
- Pick a sensible place for charging and the antenna, since RTK positioning still needs it.
With eufy Robot Lawn Mower E15
- Severe slopes, drop-offs and a highly fragmented site are not where it is the first choice.
Change of plan
When the answer changes
Your turf covers less than one eighth acre
Go with Segway Navimow i105N. One eighth acre is what the i105N is sized for, and E15 is rated for one fifth acre. So they suit different lawn sizes before navigation even comes into it. Measure the grass alone, leaving out the house, paving and beds, instead of using the lot area.
Your measured turf is over 0.125 acre but no more than 0.20 acre
Go with eufy Robot Lawn Mower E15. The larger 0.20-acre rating belongs to E15. Its 1-3-inch cutting range and 18-degree slope limit also have to meet the lawn requirements.
Decision guide
How to decide
For a smaller high-cut lawn, go with i105N. For more rated area and a camera-based setup without an RTK antenna, go with eufy E15.
Begin with your lawn and cutting needs
One eighth acre is what the i105N is sized for, and E15 is rated for one fifth acre. So they suit different lawn sizes before navigation even comes into it. Measure the grass alone, leaving out the house, paving and beds, instead of using the lot area.
Look at navigation and the path through your yard
The i105N's 2-3.6-inch range reaches taller grass settings, and E15 covers 1-3 inches. Camera-based navigation spares E15 a separate RTK antenna, but its performance still depends on the visual scene, boundaries and operating conditions.
Think through boundaries, upkeep and seasonal use
The two slope figures come in different units. Eufy publishes 18 degrees and Segway lists a 30% grade. Convert before judging the gap, since 18 degrees is much closer to 30% than to an 18% grade.
What this page can’t tell you
- These area, grade, passage and runtime figures are manufacturer claims. We did not run real-world mowing tests.
- Follow the boundary clearances and safety instructions in the installation manual. Keep people and animals clear of blades while they run.
- Headroom in the mapped area does not promise a finish time. Grass growth, weather, obstacles, allowed operating hours and charging all change the outcome.
By the numbers
What the data shows
What we found across the robotic lawn mowers we compare, plus the checked facts behind each finding.
How many fit
Only 5 of the 56 models checked meet every need here: “The area I can mow is less than a quarter acre”, “My grass has to be cut higher than three inches”, and “I am unable to place an RTK antenna”.

How we countedThe count uses each product's current fit ratings for “The area I can mow is less than a quarter acre”, “My grass has to be cut higher than three inches”, and “I am unable to place an RTK antenna”. A need with no documented match is not counted.
How we calculatedFigures are the lawn area the maker rates it for. Slopes, layout, obstacles and how often it mows can shrink the area it really covers. For context, 47 of 56 models publish comparable figures.
