Side by side
Dreame A3 AWD 1000 vs Segway Navimow i105N: Dreame handles more than an eighth acre and needs no RTK antenna
Quick verdict
A3 AWD 1000 is the choice when the lawn is larger than i105N's one-eighth-acre rating, needs a lower cut or has no room for the reference antenna. i105N is the choice for a smaller, gentler site with suitable antenna visibility and a height target within its US range. Navigation technology by itself does not guarantee trouble-free operation.
Before you buy
Why, and what it costs you
Buying the i105N means finding a place for its antenna
i105N pairs RTK with vision and needs a suitable GNSS antenna installation. If your yard cannot provide the required sky visibility, check the site before you buy. A3 uses LiDAR and cameras with no separate antenna, which makes it the more relevant candidate when antenna siting is the obstacle. Neither navigation system is guaranteed under every tree, wall or lighting condition. For a small open yard with a suitable antenna position, i105N is still a valid alternative.
Where this comes from
Required installation hardware is what drives the recommendation. It makes no claim that LiDAR always beats RTK or that a vision-assisted satellite system never loses positioning.

In practice
Differences you will notice
Buying the i105N means finding a place for its antenna
i105N pairs RTK with vision and needs a suitable GNSS antenna installation. If your yard cannot provide the required sky visibility, check the site before you buy. A3 uses LiDAR and cameras with no separate antenna, which makes it the more relevant candidate when antenna siting is the obstacle.

How we worked this out
Required installation hardware is what drives the recommendation. It makes no claim that LiDAR always beats RTK or that a vision-assisted satellite system never loses positioning.
Treat mowable area and slope as separate limits
A 0.20-acre lawn is more than i105N's 0.125-acre rating covers, yet fits A3 AWD 1000's 0.25-acre headline. Give the same lawn a 40 percent interior slope and it also goes past i105N's 30 percent figure while staying below A3's published 80 percent maximum. For those conditions, pick A3 as the candidate, then inspect edges and transitions. Pick i105N for a smaller, gentler site that also permits its 2-to-3.6-inch cutting range.
How we worked this out
0.20 acre is 60 percent over 0.125 acre. The slope check uses percent grade. It does not use degrees. Published maximums neither remove boundary setbacks nor prove safe operation beside a drop-off.
Cutting height isn't settled just because lawn size is equal
A small lawn can fit both area ratings and still favor A3 when a 1.5-inch cut is required, because i105N's US range begins at 2 inches. At a 2.5-inch target both ranges qualify, so height no longer picks a winner. Decide on installation and terrain instead. Doing so keeps buyers from importing a European Navimow variant's lower cutting range into the exact North American listing.
How we worked this out
The range is 1.2 to 3.9 inches for A3 and 2.0 to 3.6 inches for i105N. The 1.5-inch example falls 0.5 inch below the latter minimum.
Plug in your numbers
Can either mower handle your yard?
This checks hard limits only. Personal preferences are left out of the math.
Dreame A3 AWD 1000
Works with your numbersIts rating covers 0.25 acre and 80% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Segway Navimow i105N
Does not work with your numbersIts rating covers 0.125 acre and 30% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.

With Dreame A3 AWD 1000
- Boundary safety is not settled by a maximum interior slope
With Segway Navimow i105N
- You need a suitable GNSS antenna location
Change of plan
When the answer changes
Handle a lawn up to a published quarter acre
Go with Dreame A3 AWD 1000. Skip the separate RTK antenna and get down to a lower cut. No LiDAR system is immune to every site condition.
Run RTK and vision on a small open site that suits them
Go with Segway Navimow i105N. Keep the height inside the 2-to-3.6-inch US range. Larger examples are excluded by the 0.125-acre rating.
Decision guide
How to decide
Go with A3 AWD 1000 if the lawn is larger than i105N's one-eighth-acre rating, needs a lower cut or can't accommodate its reference antenna. Go with i105N for a smaller, gentler site that has suitable antenna visibility and a height target within its US range. Navigation technology alone doesn't guarantee trouble-free operation.
Buying the i105N means finding a place for its antenna
The i105N pairs RTK with vision and needs a suitable GNSS antenna installation. If your yard can't give the required sky visibility, check the site before you buy. A3 runs on LiDAR and cameras and needs no separate antenna, so it is the more relevant candidate when siting the antenna is the obstacle. Neither navigation system is guaranteed under every tree, wall or lighting condition. For a small open yard with a suitable antenna position, i105N remains a valid alternative. This recommendation follows the installation hardware each one requires. It does not claim that LiDAR always beats RTK, or that a vision-assisted satellite system never loses positioning.
Treat mowable area and slope as separate limits
Suppose a lawn is 0.20 acre. That is over i105N's 0.125-acre rating but within A3 AWD 1000's 0.25-acre headline. If the same lawn has a 40 percent interior slope, that also tops i105N's 30 percent figure while staying below A3's published 80 percent maximum. For those conditions, make A3 the candidate, then inspect edges and transitions. Choose i105N for a smaller, gentler site that also allows its 2-to-3.6-inch cutting range. 0.20 acre is 60 percent above 0.125 acre. The slope check uses percent grade, which differs from degrees. Published maximums neither remove boundary setbacks nor prove safe operation beside a drop-off.
Cutting height isn't settled just because lawn size is equal
Take a small lawn that fits both area ratings. A required 1.5-inch cut still favors A3, because i105N's US range begins at 2 inches. At a 2.5-inch target both ranges qualify, so height no longer picks a winner, and you should decide on installation and terrain instead. This keeps buyers from carrying a European Navimow variant's lower cutting range over to the exact North American listing. A3 covers 1.2 to 3.9 inches and i105N covers 2.0 to 3.6 inches. The 1.5-inch example is below the latter minimum by 0.5 inch.
