Mammotion LUBA 3 AWD vs Segway Navimow i210

Both are wire-free, all-wheel-drive 2026 mowers, but the Navimow i210 AWD is a $1,299 quarter-acre machine and the LUBA 3 AWD starts at 0.37 acre for about twice the price. Here’s where they actually overlap, how they differ under trees and on hills, and what owners and reviewers report.

This comparison is research-based. We haven’t run these two mowers side by side; the figures below are manufacturer specs and retailer listings, and the experiences are independent reviews and owner reports, labeled as such and linked in the sources.

The short answer

If you have an open lawn of a quarter acre or less with slopes under 45%, the Navimow i210 AWD does the job for $1,299. If your lawn is over a quarter acre, steeper than 45%, or largely under trees, the LUBA 3 AWD is the better match, and the variant you pick matters as much as the brand. For lawns sized between the two (around 0.25–0.37 acre), the choice comes down to tree cover and slope, which we walk through below.

Specs side by side

Two corrections to how these mowers are often described. First, not every LUBA 3 AWD uses RTK: the 1500 is LiDAR plus vision only, while the 3000 and 5000 add network RTK. Second, the US store lists three LUBA 3 AWD variants topping out at 1.25 acres; Mammotion’s global page mentions coverage up to 10,000 m² for the series, so larger versions may be sold in other regions.

Where they overlap: the quarter- to third-acre yard

On paper these mowers serve different yards, but the i210 AWD (0.25 acre, $1,299) and the LUBA 3 AWD 1500 (0.37 acre, $2,399) sit right next to each other. That’s the real decision for most people reading this page. For about $1,100 more, the LUBA 1500 gives you:

• Nearly twice the slope rating (80% vs. 45%).
• Navigation that doesn’t depend on satellites, which matters under trees and beside tall walls.
• A cutting deck more than twice as wide, so fewer passes on the same lawn.
• About 50% more rated area, which is headroom if your yard is irregular.

What you give up: about $1,100, a smaller and lighter machine (the LUBA weighs 41 lb vs. 27.1 lb for the i210 AWD), and the i210’s quieter running (Segway lists 59 dB(A) vs. Mammotion’s ≤70 dB). One pricing quirk: when we checked, Mammotion’s US store had the larger LUBA 3 AWD 3000 on sale for less than the 1500, so compare current prices across variants before you pick the smallest one. Segway’s own middle step, the Navimow i215 LiDAR ($1,599, 0.37 acre), is also worth a look if you want LiDAR at this size without moving to Mammotion.

Under trees and near the house

The i210 AWD uses network RTK plus cameras. That’s a strong combination on open lawns, but RTK needs sky view, so heavy canopy or a lawn squeezed between houses is where it is most likely to need help. A Dutch buying guide for the sister i206 AWD (not a hands-on test) summarizes user reports as excellent navigation in open gardens and problems in built-up situations.

The LUBA 3 AWD’s LiDAR is its answer to that. EasyLawnMowing tested a LUBA 3 AWD 5000 on a farm property with dense trees and reported it navigated under them far better than the older LUBA 2 in the same place. TechRadar’s reviewer found the 3000 worked well in shaded areas without satellite obstruction problems.

How RTK, network RTK and LiDAR differ is covered in our guide to wire-free robot mowers and GPS/RTK.

On slopes

Both are all-wheel drive, but the ratings are far apart: 45% for the i210 AWD and 80% for the LUBA 3 AWD. TechRadar’s reviewer took the LUBA 3 AWD 3000 up a very steep playground bank to check the 80% claim and came away impressed. The i210 AWD’s traction and stability control are designed to be gentle on turf; TechRadar’s CES coverage singled out its ability to turn without tearing grass. If your steepest section measures under about 40%, the i210 has margin; above that, the LUBA is the only one of the two rated for it.

What reviewers and owners report

Independent reviews (hands-on):

• LUBA 3 AWD 3000, TechRadar: easy setup with no boundary wire, clean striped cut, and strong slope performance; downsides were front wheels tearing grass in soft, shady soil on sharp turns, app connectivity quirks and mud collecting in the omni-wheels.
• LUBA 3 AWD 5000, EasyLawnMowing: simple setup and much better tree navigation than the LUBA 2; the mower got stuck in an unmapped ditch (the reviewer called it user error) and he missed LUBA 2’s resume-from-percentage option.

Firmware follow-up: Mammotion’s April 15, 2026 LUBA 3 release log adds partial map editing and adjusts motor speed during turns to reduce turf damage, which speaks directly to the torn-grass complaint.

Owner reports (unverified, individual experiences):

• Mammotion on Trustpilot (3.6/5 from about 2,800 reviews when we checked): owners praise setup and cut quality, but recurring complaints include slow support and repairs, parts availability, mowers stopping mid-job or failing to dock, and hardware faults within warranty.
• Segway Navimow on Trustpilot (4.2/5 from about 840 reviews when we checked): owners praise easy setup, cut quality and support; complaints include fiddly mapping, antenna or signal setup, and firmware updates needing reboots. One i210 AWD owner reported poor obstacle avoidance, including a close call with a child, which is a reminder to keep kids and pets off the lawn while any robot mower runs.

Which yard suits which

• Under 1/4 acre, open, slopes under 45%: Navimow i210 AWD. Less money, quieter, and nothing here needs LiDAR.
• Under 0.15 acre: the i206 AWD ($999) covers it; skip both of the bigger machines.
• 1/4 to 0.37 acre with trees or tight side yards: LUBA 3 AWD 1500 (LiDAR + vision) or Navimow i215 LiDAR.
• Any size with slopes above 45%: LUBA 3 AWD.
• 0.37 to 1.25 acres: LUBA 3 AWD 3000 or 5000; the i210 AWD is simply too small. For big, gentler lawns also compare the Navimow X3 series in our robot mower buying guide by yard size.
