The wire-free robotic mower category went from “one player worth taking seriously” to “five brands fighting for the same buyer” in about 18 months. If you are shopping for a wire-free RTK mower under $4,000, the realistic shortlist in 2026 is Segway’s Navimow, China-based Mammotion, and Worx Vision.
This is a head-to-head on the three brands a typical homeowner is actually choosing between. We will lay out which brand is the right pick for each yard profile, with honest disclosure of where each one falls short.
Quick Verdict by Yard Profile
Sloped yards (over 30%): Navimow i206 AWD at the price tier, Mammotion LUBA AWD if budget allows for extreme-slope edge cases.
Larger yards (1/2 acre+): Mammotion LUBA AWD for AWD coverage, otherwise Husqvarna.
Tight budget under $1,500: Navimow. Worx Vision exists but is behind on software maturity.
The Three Brands at a Glance
| Spec | Navimow | Mammotion LUBA | Worx Vision |
|---|---|---|---|
| Headline model | i110N / i206 AWD | LUBA AWD 1000/3000/5000 | Worx Vision M800 |
| Price range | $899-$929 | $1,999-$4,499 | $1,499-$1,799 |
| Coverage | 0.15 – 1/4 acre | 1/4 – 1.25 acre | ~0.18 acre |
| Slope rating | 45% (i206 AWD) | Up to 75% (premium) | ~30% |
| Positioning | EFLS NRTK + Vision | RTK + Vision | Vision-only |
| Software maturity | Multi-generation | Multi-generation | First-generation |
Navimow: The Default Pick
RTK + Vision
Navimow i110N (most yards)
1/4 acre · RTK + Vision · Wire-free app-mapped · Best $/sq ft
$929
Navimow has been iterating wire-free RTK for several generations. EFLS NRTK runs on cellular networks instead of requiring a hardware reference station. The app is the most mature in this group. Price points are accessible without compromising the wire-free core.
Where Navimow loses
- Larger yards: 1/4 acre is the current US ceiling.
- Extreme slopes past 45%: Mammotion claims 75%.
- Brand recognition: Worx and Husqvarna have stronger US name recognition.
EFLS NRTK + Vision
Navimow i206 AWD (sloped yards)
0.15 acre · 45% slope AWD · EFLS NRTK + Vision · Garage S included
$899
Mammotion LUBA AWD: The Scale-Up
Where Mammotion wins
Mammotion’s LUBA AWD line is the most aggressive on coverage and slope numbers in the wire-free segment. The LUBA AWD 5000 covers up to 1.25 acres and rates 75% slope on the top trim.
Where Mammotion loses
App polish: Functional but earlier-generation UX vs Navimow.
NRTK without dedicated hardware: Mammotion’s RTK setup has more install steps than Navimow’s network-based approach.
Who should consider Mammotion
If your yard is over 1/2 acre and you do not want to step up to Husqvarna’s $4,500+ tier, Mammotion’s LUBA AWD 3000 is the realistic option. For 1/4 acre or smaller, paying the Mammotion premium is hard to justify.
Worx Vision: The Newcomer
Where Worx wins
Worx has US brand recognition from their wired Landroid line and a domestic service infrastructure most Chinese-headquartered competitors do not match. The Vision M800 ships at $1,499-$1,799 with vision-based perimeter mapping.
Where Worx loses
Software maturity: First-generation product. Mapping errors, getting-stuck incidents, edge cases the firmware has not learned yet.
Slope: ~30% rating – sloped yards belong on Navimow i206 AWD or Mammotion AWD.
The Honest Picking Logic
- Yard size first. Over 1/2 acre: Mammotion. Under 1/4 acre: Navimow or Worx.
- Slope second. Over 30%: Navimow i206 AWD or Mammotion AWD. Under 30%: Navimow i110N.
- Brand preference third. Strong Worx loyalty: Vision. Brand-agnostic: Navimow.
- Budget last. Most homeowners do not need to spend over $1,000 for wire-free RTK that works.
Long-Term Cost Comparison
| 5-year cost | Navimow i110N | Mammotion LUBA 3000 | Worx Vision M800 |
|---|---|---|---|
| Unit | $929 | $2,999 | $1,799 |
| Shelter | $60 | $200 | $80 |
| Blades | ~$60 | ~$120 | ~$70 |
| Battery | ~$200 | ~$400 | ~$250 |
| Service | ~$100 | ~$200 | ~$200 |
| 5-year total | ~$1,349 | ~$3,919 | ~$2,399 |
What All Three Brands Get Wrong
- None of them eliminate string-trimming around hard edges.
- None of them handle bagging – all mulch clippings.
- None of them are zero-maintenance.
- All three need reasonable connectivity.
Bottom Line
For the typical US homeowner shopping wire-free RTK robotic mowers in 2026:
- The default pick is Navimow. Price-to-capability ratio is the best in the segment.
- Mammotion earns its premium only on larger lots or extreme slopes.
- Worx Vision matters if Worx brand trust outweighs the first-generation software gap.
