YARBO Robot Lawn Mower Pro: lawn size, cutting width and how far it drives
A mower rated for 6 acre with a 20 in deck, measured against the 40 RTK robot mowers in this corpus — including how far it must travel to cut that lawn once, which the listing does not state.
Every figure below is read from the manufacturer’s own listing. We do not test robot mowers and nothing here has been unboxed, mapped or driven across a lawn. Where the listing is silent, this page prints not stated rather than a plausible default, and the figure no manufacturer publishes — the distance the mower covers in one full cut — is arithmetic on two figures that are published, shown with its working.

How far it has to drive
A robot mower cuts a strip as wide as its deck and then comes back for the next one. Divide the lawn it claims by the width it cuts and this one has to travel 29.7 miles to get over 6 acre once — at 20 in a pass. Neither number is a secret and their product is on no listing anywhere, which is a shame, because it is the figure that explains the rest of the machine: why it is out every day instead of twice a week, why it runs for hours rather than minutes, and why two mowers sold for the same lawn can behave nothing like each other.
It also puts the deck width in proportion. Cutting width is the specification that reads like a detail and behaves like the main event: the distance is inversely proportional to it, so an inch or two either way moves this figure by miles. A wider deck is not a refinement over a narrower one on the same lawn, it is straightforwardly less driving — less wear, fewer hours, fewer charge cycles to reach the same cut.
This is a distance, not a duration. Turning it into hours needs a travel speed, and not one listing in this corpus publishes one — so this site does not estimate it. Overlap between passes, time spent turning, and the trip back to the dock all add to the real figure too. Treat 29.7 miles as the floor on how far the machine goes, and a way to compare two mowers on the same lawn, rather than as a prediction of your afternoon.
How it compares with its own class
Against the 40 RTK robot mowers in this corpus, rather than against a generic alternative:
| Measure | This one | Class median | Where it sits |
|---|---|---|---|
| Lawn size claimed | 6 acre | 10,890 sq ft | above the class median of 10890 sq ft |
| Cutting width | 20 in | 8.7 in | above the class median of 221 mm |
| Distance per full cut (derived) | 29.7 miles | 3.1 miles | above the class median of 16542 ft |
A mower on the class median is not a worse buy than one above it. A larger claimed lawn size is the specification most easily inflated, because it is a claim about hours available rather than a physical limit — and the mower that claims less may simply be describing itself more honestly. The cut distance is the figure worth weighing, because it is arithmetic on two numbers rather than a marketing judgement about either.
Where it suits
- A lawn up to about 6 acre, measured rather than estimated — and measured as mown area, not plot size.
- A garden where burying a perimeter wire is unwelcome, since this one states it does not need one.
- Getting the job done in fewer passes: at 20 in this deck is wide for a robot mower, and the distance figure above shows what that buys.
- An open lawn with a clear view of the sky, which is what RTK positioning needs to be accurate.
Where it does not
- A sloping garden. This listing states no slope rating at all, so there is nothing to check a bank against.
- Anyone expecting a quick cut: 29.7 miles per pass over the whole lawn means this machine is out for hours, most days.
- Consistently wet or loose ground, where two-wheel drive is the usual thing to run out of.
What the listing claims
These are the manufacturer’s statements, not findings. Nothing on this page has been measured by anyone here, and a specification stated on a listing is a claim until the unit is in front of you.
It states lawn size claimed, cutting width, distance per full cut, navigation, boundary, cutting height. It does not state a slope rating.
The gaps matter as much as the figures. A listing that omits a slope rating is not describing a mower that cannot climb, it is describing itself incompletely — and slope is the specification that most often decides whether a robot mower works in a particular garden at all, because unlike lawn size it cannot be worked around by running the machine more often.
What no listing on this site tells you
Three things decide whether a robot mower earns its place, and none is a specification any manufacturer publishes. The first is transit time. At 6 acre the machine spends a real share of every session driving between zones rather than cutting, and that share grows with every obstacle and narrow link between them. An area figure is measured as if the lawn were one open field; almost no lawn this size is.
The second is what happens when it gets stuck, which it will, and without all-wheel drive the list is longer. Wet grass on any slope, a shallow root, a soft patch after rain, the lip where lawn meets path — all of these strand a two-wheel machine that would have driven over them on four. What matters then is whether it tells you, and how far you walk to find it. Neither is a specification, and together they are most of the difference between a mower that saves an hour a week and one that costs an hour a week.
The third is the boundary, decided once and lived with. Wire-free is the easier installation and the harder promise: nothing physical stops the machine leaving the lawn, so the edge is only as good as the positioning on a bad day — under trees, against a wall, after the neighbours build something that was not there when it mapped the garden. When it drifts, it drifts into a flower bed rather than stopping at a wire.
Before you decide
Measure the lawn, do not estimate it
6 acre is a ceiling on mown grass, not on the plot. Beds, paths, the patio and the shed come off before the comparison is fair, and on a garden this size that subtraction is frequently a quarter of the plot. People routinely over-estimate a lawn by a third, which at this rating is the difference between a mower that finishes and one that never quite does.
Settle the slope question elsewhere
This listing states no slope rating, so the question cannot be answered from it at all. If any part of your garden is more than gently graded, that silence is the specification to go looking for before anything else on this page matters.
Treat marketing language as a claim
Where a phrase on the listing matters to your decision, look for the number behind it: a stated slope percentage rather than a sentence about handling hills, a stated cutting width rather than a promise of efficiency. This listing documents itself better than most in the corpus, which makes the gaps that remain more conspicuous. Where this site could not find a number, it says not stated.
If the lawn size fits and the slope rating clears your worst bank, the current price and availability are on Amazon — this site deliberately does not quote either, because both are stale within days of being read.
