When your property runs into multiple acres, the shortlist narrows fast — most robot mowers top out around 1.5 acres. Two that don’t: the Segway Navimow Terranox and the Yarbo Pro, each rated to about 6 acres per unit. The spec table above lines them up; the real decision is what kind of machine you want behind that coverage.
Same coverage, different machines
The Terranox (the CM240M1 here) is a dedicated commercial-grade mower — wheeled all-wheel drive, a 17″ dual-disc deck driven by dual 180W motors, built for long daily runs on big turf. It’s Navimow’s answer for property managers and acreage owners who want one job done well: mowing, at scale.
The Yarbo Pro gets to the same ~6 acres a different way: a tracked robot with a 20″ deck, built to crawl over rough, ditched, uneven ground. And it’s part of the modular Yarbo Core — which is the whole story below.
The Yarbo’s ace: it’s not only a mower
The Terranox mows. The Yarbo Core swaps modules — the same robot becomes a snow blower or a leaf blower. On a big property, that’s a genuine year-round labor saver, and it’s a big part of why the Yarbo Pro costs less than the Terranox while arguably doing more. If your acreage comes with a long winter driveway and a fall full of leaves, that versatility is hard to ignore.
When the Terranox still wins
Modularity isn’t free of trade-offs. The Terranox is a purpose-built mower with Navimow’s commercial ecosystem, wheeled AWD that’s efficient on open turf, and a single-job simplicity some operators prefer. For a pure large-scale mowing operation — a landscaper, an HOA, a big open estate — a dedicated machine can be the more reliable, more efficient choice.
So which should you buy?
- Buy the Navimow Terranox for dedicated, large-scale mowing on open acreage, especially in a commercial or property-management setting.
- Buy the Yarbo Pro for value and versatility — rough or ditched ground, a lower price, and a robot that also clears snow and leaves through the year.
And one more option worth weighing on 2–3 acres: instead of a single commercial machine, two residential mowers as a team can cost about the same, cut in roughly half the time, and give you a backup. Which route wins comes down to your exact acreage and layout — the free lawn check sizes all of it. (More in best robot mower for large lawns.)
Frequently asked
Terranox or Yarbo Pro for a large property?
Both are rated to about 6 acres per unit, so either can handle real acreage. The Navimow Terranox is a dedicated commercial-grade mower on wheeled all-wheel drive — the pick if mowing at scale is all you need, with Navimow's ecosystem behind it. The Yarbo Pro costs less, runs on tracks for rough ground, and is modular — the pick if you also want snow and leaf duty or better value.
Does the Yarbo really cover as much as the commercial Terranox?
On paper, yes — both are rated to roughly 6 acres per unit. The difference is how they get there: the Terranox is a purpose-built commercial mower, while the Yarbo Pro is a large tracked platform that happens to also cover that much. On very rough or ditched ground the tracks help the Yarbo; on open acreage the wheeled Terranox is efficient.
Which is cheaper?
The Yarbo Pro is the lower-priced of the two — and it does more than mow, since the Core swaps to a snow blower or leaf blower. The Terranox costs more as a dedicated commercial machine. For a big property where you also dread the winter driveway, the Yarbo's math is hard to beat.
Are these overkill for a normal yard?
For most residential lawns, yes. If your mowable area is under ~1.5 acres, a Navimow X450 or a Mammotion LUBA 3 is the right size and far less money. The Terranox and Yarbo Pro earn their keep on multi-acre properties — or you can run two smaller mowers as a team, which is sometimes the better play. We size it either way on your free lawn check.
