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
If measured grass stays near 5,000 square feet, buy the i105N. The i110N doubles the rated area to a quarter acre, so it is the safer pick for a larger lawn or a tight weekly mowing window.
Before you buy
The published “Rated area” figure is 100% higher on Segway Navimow i110N: 0.25 acre, against 0.125 acre on Segway Navimow i105N.
Where this comes from
Use this published coverage as a sizing limit under the stated conditions. It is not a guarantee for every layout. The percentage is worked out from the lower published figure.

The catch
Deep ruts or very steep ground are not a good match for two-wheel drive.

Trade-offs
Decision guide
Start by measuring the grass. Step up to the bigger model only if the smaller rating can't give you a workable weekly schedule.
Both have the same cutting range and navigation approach. Choosing the i110N is mostly about getting twice the rated grass area and the reserve that gives you.
Once you take out the home, driveway, beds and patio, a 10,000-square-foot parcel may hold far less grass.
