Mammotion vs Segway Navimow Robot Mower: 5 Simple Specs

8 min read by Tyler Novak Updated November 11, 2026

Mammotion vs Segway Navimow robot mower: neither brand wins on every spec. On the ratings each company publishes, Mammotion’s LUBA 3 AWD listing claims a higher slope rating (80%, or 38.6°) than the Navimow i110 (30%, or 17°), while Navimow’s top i-series LiDAR Pro models list 55% (29°). Positioning, cutting height, and noise also differ. The better fit depends on your steepest slope, your lawn size, and how much RTK setup you are willing to do.

The short answer

Slope: Mammotion LUBA 3 AWD is listed at 80% (38.6°). Navimow i110 is listed at 30% (17°), and the i205 to i220 LiDAR models at 45% (24°).
Cutting height: LUBA 3 AWD standard version 1.0 to 2.7 in, high version 2.2 to 4.0 in. Navimow i110 2.0 to 3.6 in.
Positioning: LUBA 3 AWD uses 360° LiDAR, NetRTK, and camera AI vision with no RTK installation. Navimow i110 uses Network RTK with a vision-based backup.
Our reading: start with your steepest slope, then check lawn size, then compare positioning and noise.

Where the two brands stand

Both companies sell several robot mower lines, and their names do not map neatly onto each other. Mammotion’s LUBA AWD series is organized by lawn size and cutting-height version. Segway Navimow’s i-series splits models by positioning type (AWD, LiDAR, or LiDAR Pro) and by slope rating. Comparing a single model from one brand with a single model from the other is more useful than comparing the two brand names.

This comparison of the Mammotion vs Segway Navimow robot mower lines uses the spec pages each company publishes. It does not rank the mowers or claim that either brand has been tested in a yard. Where a number is our interpretation rather than a published figure, we say so. For a different brand pairing, see Chinese robot mower brands vs Husqvarna.

Spec	Mammotion LUBA 3 AWD (US listing)	Navimow i110	Navimow i205 to i220 (LiDAR)
Max slope	80% (38.6°)	30% (17°)	45% (24°)
Cutting height	1.0 to 2.7 in (standard), 2.2 to 4.0 in (high)	2.0 to 3.6 in	Not stated on the i-series page
Rated coverage	0.37 to 1.25 acres by model	0.25 acre	125 to 560 m² per charge
Positioning	360° LiDAR, NetRTK, camera AI vision, no RTK install	Network RTK with EFLS 2.0 vision backup	LiDAR (named in model names only)
Noise	70 dB or less	58 dB(A)	Not stated on the i-series page

Slope ratings and traction

Slope is the spec most buyers check first when they compare a Mammotion vs Segway Navimow robot mower, and it is also the one most easily misread. Mammotion’s US LUBA AWD listing describes the LUBA 3 AWD as climbing slopes up to 80% (38.6°) with four in-wheel motors and all-wheel drive. Navimow’s i110 page lists climbing capability up to 30% (17°) with front-wheel drive. The i-series page lists 45% (24°) for the i205 AWD, i208 AWD, and LiDAR models from i208 to i220, and 55% (29°) for the i210 LiDAR Pro and i220 LiDAR Pro.

The gap is large on paper, but it does not tell you how a mower handles a wet, uneven, or grassy slope. Slope ratings also come from each company’s own test conditions, which are not published in a form that lets you compare them directly. Treat the numbers as the maximum each company will claim, not as a guarantee on your hill. Our guide to robot mower slope ratings explained shows how to read them.

Cutting height and lawn size

Cutting height and rated coverage tell you whether a model fits the grass and the yard. The LUBA 3 AWD listing gives a standard version at 1.0 to 2.7 in and a high version at 2.2 to 4.0 in, with rated coverage of 0.37 acre for the 1500 model, 0.75 acre for the 3000 model, and 1.25 acres for the 5000 model. The i110 is adjustable from 2.0 to 3.6 in, and its product title rates it for a 0.25 acre lawn.

Navimow’s i-series page gives a different kind of figure: lawn area per charge and a recommended lawn size. The i205 AWD is listed at 125 m² per charge for lawns of 500 to 1000 m², and the i220 LiDAR at 560 m² per charge for lawns of 800 to 2000 m². These two ways of expressing coverage are not directly interchangeable, so check the sizing guidance on the exact model you are considering. The robot mower coverage rating explained guide covers the difference in more detail.

For grass height, the right setting depends on the grass species and the season, so the range a mower offers matters less than whether it covers the height your lawn needs.

Positioning and setup

Positioning is where the two approaches differ most. The LUBA 3 AWD listing describes Tri-Fusion positioning that combines 360° LiDAR, NetRTK, and dual-camera AI vision, and says it needs no RTK installation. Navimow’s i110 page describes Network RTK, which needs no local antenna in areas where network coverage is available, and an EFLS 2.0 vision system that takes over when the satellite signal is weak.

The practical question is coverage in your area. Navimow’s page lets you check Network RTK availability by location. Mammotion’s listing also uses NetRTK, but says no RTK installation is needed, so the setup burden is different. Our explainer on RTK vs LiDAR vs vision robot mowers covers the trade-offs. Either way, check the setup requirements for your exact model before you buy, because the included hardware varies by version.

Noise levels

Noise is a quality-of-life spec for a mower that runs most days. The i110 page lists 58 dB(A), and the LUBA 3 AWD listing gives a noise level of 70 dB or less. Those figures come from each brand and were measured under different conditions, so they are not a like-for-like comparison.

A quieter mower matters most if it runs early in the morning or near a neighbor’s windows. Compare the two numbers as a rough guide only, and look for independent measurements if noise is a deciding factor for you. For general figures, see how loud robot mowers are.

Mammotion vs Segway Navimow robot mower: what to check

Once the headline specs are on one page, the choice usually comes down to a few questions. This is our reading of the published figures, not a verdict from hands-on use.

Measure your steepest slope. If it is near 30%, the i110 rating is close to the limit. If it is above 45%, only the Mammotion listing and the Navimow LiDAR Pro models fall in range on paper.
Measure the lawn area. Match the rated coverage or recommended lawn size to your yard, and leave room for flower beds and paths.
Check positioning coverage. If you have a poor view of the sky or live where Network RTK is weak, look harder at the LiDAR and vision options.
Confirm the model version. Cutting height, slope, and coverage change between standard, high, and LiDAR variants of the same line.

Heads up

The two companies test and publish slope and noise figures under different conditions. When you compare a Mammotion vs Segway Navimow robot mower, use the spec sheet of the exact model you plan to buy, not the brand name.

Frequently asked questions

Is Mammotion better than Navimow for steep yards?

In the Mammotion vs Segway Navimow robot mower comparison, the published ratings put the Mammotion LUBA 3 AWD line higher (80%, or 38.6°) than any Navimow i-series model on the pages we read, where the top rating is 55% (29°). Those are the maximum each brand claims under its own conditions, so a steep yard still needs a site check.

Do I need an RTK base station for either mower?

The LUBA 3 AWD listing says no RTK installation is needed because it uses LiDAR, NetRTK, and camera vision. The Navimow i110 uses Network RTK with no local antenna where network coverage is available. Check coverage in your area before you assume either setup will work.

Which one cuts lower?

The Mammotion standard version goes down to 1.0 in, while the Navimow i110 starts at 2.0 in. The Mammotion high version starts at 2.2 in and reaches 4.0 in. Lower is not automatically better: match the height to your grass species and the season.

Is one of them quieter?

The Navimow i110 page lists 58 dB(A), and the LUBA 3 AWD listing says 70 dB or less. The two figures were measured under different conditions, so use them as a rough guide and compare independent tests if noise matters to you.
