Main trade-off
Segway Navimow i105N
Its one-eighth-acre rating leaves little room for an oversized or rapidly growing lawn.
Head-to-head
Segway Navimow i105N vs eufy Robot Lawn Mower E15: E15 covers more grass without an RTK antenna, i105N suits taller cuts
The short answer
Choose i105N for a smaller high-cut lawn or eufy E15 for more rated area and camera-based setup without an RTK antenna.
Before you choose
The reasoning and the trade-offs
A 0.16-acre lawn is too large for i105N's rating
It exceeds i105N by 0.035 acre and leaves 0.04 acre below E15's rating.
What this is based on
0.160 - 0.125 = 0.035 acre. 0.200 - 0.160 = 0.040 acre.
Main trade-off

Winner by situation
Start with what you need it to do
A 0.16-acre lawn is too large for i105N's rating
It exceeds i105N by 0.035 acre and leaves 0.04 acre below E15's rating. 0.160 - 0.125 = 0.035 acre. 0.200 - 0.160 = 0.040 acre.

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

A 3.5-inch cut selects i105N within this pair
E15's 3-inch maximum falls half an inch short. The desired height remains within i105N's 2-3.6-inch range. 3.5 - 3 = 0.5 inch. This compares range endpoints, with available adjustment steps still to be checked.

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

What matters in practice
The differences that matter
A 0.16-acre lawn is too large for i105N's rating
It exceeds i105N by 0.035 acre and leaves 0.04 acre below E15's rating.
How we reached this conclusion
0.160 - 0.125 = 0.035 acre. 0.200 - 0.160 = 0.040 acre.

Choice A
Segway, i105N
Navimow i105N
The smaller Navimow i Series model brings virtual boundaries and camera-assisted obstacle detection to an eighth-acre lawn.
- Best matched use
- Compact suburban lawns where a simple wire-free setup matters
Checked facts
- Segway rates the i105N for 0.125 acre.
- The published cutting range is 2.0 to 3.6 inches.
- The i Series combines RTK positioning with camera-based obstacle recognition.
Choice B
eufy, E15
Robot Lawn Mower E15
A camera-led mower that maps without wire, RTK antenna or LiDAR hardware, making setup unusually clean on a simple small lawn.
- Best matched use
- Small, clearly bordered lawns where the owner wants the least mapping hardware
Checked facts
- eufy rates the E15 for lawns up to 0.2 acre.
- Its navigation uses cameras and needs no boundary wire or RTK antenna.
- The mower plans parallel routes after automatic lawn mapping.
Meaningful differences
What changes the fit
| What changes | Segway Navimow i105N | eufy Robot Lawn Mower E15 | Why it matters |
|---|---|---|---|
| Rated grass area | 0.125 acre | 0.2 acre | The i105N is sized for one eighth acre, while E15 is rated for one fifth acre. They therefore suit different sizes even before comparing navigation. Measure grass alone, excluding the house, paving and beds, rather than using the property-lot area. |
| Cutting-height range | 2-3.6 inches | 1-3 inches | The selected height must sit within the exact US model's range. H variants can have different minimum heights from a larger standard model. |
| Positioning and installation | RTK and vision with a reference antenna | Camera-based navigation, no RTK station | i105N's 2-3.6-inch range reaches taller grass settings, while E15 spans 1-3 inches. E15's camera-based navigation avoids 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 | Use a measured rise-over-run grade. Maximum interior climbing ratings do not establish the allowable slope beside a boundary, pond or drop. |
| Combined cutting width | 7.1 inches | 8 inches | Cutting width describes the grass swath, not body width or a guaranteed gate clearance. Turns, overlap and charging determine the real work rate. |
What you give up
Every choice has a cost
If you choose Segway Navimow i105N
- RTK positioning still needs a sensible charging and antenna location.
If you choose eufy Robot Lawn Mower E15
- It is not the first choice for severe slopes, drop-offs or a highly fragmented site.
Recommendation switch
The decision flips if...
Your turf area is below one eighth acre
Choose Segway Navimow i105N. The i105N is sized for one eighth acre, while E15 is rated for one fifth acre. They therefore suit different sizes even before comparing navigation. Measure grass alone, excluding the house, paving and beds, rather than using the property-lot area.
Your measured turf exceeds 0.125 acre and is no more than 0.20 acre
Choose eufy Robot Lawn Mower E15. E15 provides the larger 0.20-acre rating. Its 1-3-inch cutting range and 18-degree slope limit must also meet the lawn requirements.
What matters in practice
How to make the call
Start with the lawn and cutting requirement
The i105N is sized for one eighth acre, while E15 is rated for one fifth acre. They therefore suit different sizes even before comparing navigation. Measure grass alone, excluding the house, paving and beds, rather than using the property-lot area.
Check navigation and the route through the yard
i105N's 2-3.6-inch range reaches taller grass settings, while E15 spans 1-3 inches. E15's camera-based navigation avoids a separate RTK antenna, but its performance still depends on the visual scene, boundaries and operating conditions.
Plan boundaries, maintenance and seasonal use
The slope numbers use different units. Eufy publishes 18 degrees, while Segway lists 30% grade. Convert them before judging the difference, because 18 degrees is much closer to 30% than to an 18% grade.
What this comparison cannot tell you
- Area, grade, passage and runtime figures are manufacturer claims, not our real-world mowing tests.
- Use the installation manual's boundary clearances and safety instructions. Keep people and animals away from operating blades.
- Mapped area headroom does not promise a completion time. Growth, weather, obstacles, allowed operating hours and charging change the result.

Match countThe count uses the current product-to-need assignments for “My mowable lawn is under a quarter acre”, “My grass needs a cut above three inches”, and “I cannot place an RTK antenna”. A need with no documented match does not count.
Calculation noteThis compares the maker-rated lawn area. Slope, layout, obstacles and mowing frequency can reduce practical coverage. 47 of 56 models have comparable published figures for context.
