Segway Navimow X420 vs Mammotion LUBA 3 AWD 3000

The two highest-scoring mowers we list: the Navimow cuts wider, higher and to the edge; the LUBA covers 3,000 m², adds LiDAR to RTK and runs twice as long.

Verdict

The Segway Navimow X420 has the higher Verdict Score, 89 to 85.

Both are all-wheel-drive machines rated for slopes most gardens never have, 84% on the Segway and 80% on the Mammotion, both position by network RTK with a camera, both publish theft protection, a PIN lock, a rain sensor and a three-year warranty. What separates them is what each adds on top.

The Segway Navimow X420 cuts a 430 mm swathe against 400 mm, from 20 to 95 mm against 25 to 70 mm, cuts to the edge, and publishes 120 zones. It runs 90 minutes per charge and is rated for 2,000 m². The Mammotion LUBA 3 AWD 3000 adds LiDAR to RTK and the camera, so it keeps its position under trees where satellites drop out, publishes a 175-minute runtime, is rated for 3,000 m², passes a 700 mm gap, and stands 279 mm tall against the Segway's 351 mm. It is 2 dB louder, 70 against 68.

Our engine has the Segway ahead, 89 to 85, on the cutting subscore. For an open lawn up to 2,000 m² with a lot of edge to trim it is the better mower. For a larger garden, one with tree cover, or one where the mower has to squeeze through gates, the LUBA's LiDAR and runtime are what you are paying for.

Pros
  • 84% slope rating on four-wheel drive with dual suspension, and a 7 cm vertical step
  • 430 mm twin-disc deck, two 180 W motors, 20 to 95 mm cutting height
  • Network RTK with a 360° camera, no antenna to install; 120 zones
  • LiDAR, network RTK and two cameras together; no antenna to install
  • 165 W cutting motors on a 400 mm twin-disc deck

Cons
  • 28.8 kg and 85 cm long, with no passage width stated
  • 68 dB, the loudest Navimow
  • No LiDAR: positioning needs satellites, with the camera as backup
  • No edge cutting, so a border strip still needs trimming
  • 70 cm minimum passage and a 69 cm long chassis
  • 70 dB stated, against under 65 dB for the LUBA mini 2
Best for
  • Large, sloped or rough lawns around 2,000 m²
  • Thick grass and long cutting heights that a 220 mm deck cannot manage
  • Sloped plots between 1,500 and 3,000 m²
  • Thick, fast-growing grass and gardens with tree cover

In green: the better figure where the direction is beyond argument, such as more lawn or less noise. Where it depends on your home, nothing is marked.
