claims
Cutting width is one of the first numbers people compare on robot-mower pages.
But official specs usually pair cutting width with other constraints: battery
runtime, charging time, area-capacity assumptions, slope context, and navigation
behavior. If you compare width in isolation, you can overestimate how much grass
a mower can actually finish in your yard.

What official sources are actually saying
1) Navimow i Series publishes cutting width together with area-capacity and runtime context
On the Navimow i Series spec page, Segway lists a 7.1 in cutting width and
also publishes additional capacity context, including:
- Area Capacity per Hour: 60–100 ㎡ (0.015–0.025 acre) or 80–120 ㎡
(0.02–0.03 acre), depending on variant
- Full Charge Mowing Time: 60 min or 120 min
- Charging Time: 90 min or 120 min
Practical takeaway: the same cutting-width family still has different throughput
outcomes once battery/runtime variant is included.
2) Husqvarna 450X NERA publishes a 24 cm cutting width, plus runtime and charging metrics
Husqvarna’s 450X NERA page lists:
- Cutting width: 24 cm
- Typical mow time on one charge: 145 min
- Typical charging time: 40 min
- Working area capacity (±20): 5,000 m²
Practical takeaway: width is only one input. Husqvarna also frames performance
using typical cycle timing and installation-scale assumptions.
3) Mammotion LUBA 2 AWD combines width and per-charge area claims
The Mammotion LUBA 2 AWD page highlights:
- “Maximum 1500㎡/per charge with 400mm dual cutting disc”
- “Automatic Edge Mapping for 5,000㎡”
Practical takeaway: this page presents a larger cutting-disc figure alongside
per-charge area and mapped-area framing. Buyers still need to confirm yard
complexity and conditions before assuming equivalent real-world throughput.
Why width-only comparisons break
A bigger cutting width can help, but official pages show that output is
constrained by more than blade span:
- Runtime per charge (minutes) can differ substantially.
- Charging time affects total daily mowing windows.
- Area-capacity claims can depend on model variant and test context.
- Mapping/zone complexity and obstacle density can reduce effective throughput.
- Slope and traction limits can force slower or less efficient pathing.
Side-by-side context from official pages
| Source/model context | Published cutting width | Additional throughput context on same source |
|---|---|---|
| Segway Navimow i Series spec page | 7.1 in | Area Capacity per Hour ranges + Full Charge Mowing Time + Charging Time |
| Husqvarna Automower 450X NERA spec page | 24 cm | Typical mow time on one charge + typical charging time + 5,000 m² working-area framing |
| Mammotion LUBA 2 AWD page | 400 mm dual cutting disc | “Maximum 1500㎡/per charge” + 5,000㎡ mapping framing |
Quick normalization checklist before purchase
- Convert all width figures to one unit (cm or inches) before comparing.
- Pair width with published full-charge mowing time.
- Pair width with charging time to estimate cycle efficiency over a day.
- Use manufacturer area-capacity ranges (if provided) instead of width alone.
- Check whether claims are tied to a specific model variant in the same family.
- Treat “maximum” area claims as best-case, not guaranteed yard outcomes.
- Re-check spec wording immediately before purchase because pages can change.

Frequently Asked Questions
Does a wider cutting width always mean a mower will finish faster?
No. Width helps, but battery runtime, charging cycles, slope handling, and
navigation conditions can change total completion time.
Can I compare 7.1 in and 24 cm directly?
Yes, but only after unit conversion and only as one part of a broader comparison
that includes runtime and area-capacity context.
Are “maximum area” claims reliable for every yard?
They are useful as reference points, but they are usually best-case figures.
Real yards with narrow passages, many zones, edges, and obstacles can produce
different outcomes.

Reverification note
This is a time-sensitive comparison. Re-check official model pages right before
purchase, especially where “maximum area” and variant-level spec tables are
involved.
