YARDCARE 2026 New M800Plus Robot Lawn Mower: lawn size, cutting width and how far it drives
A mower rated for 8,611 sq ft with a 7 in deck, measured against the 14 camera-navigated 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 2.8 miles to get over 8,611 sq ft once — at 7 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 2.8 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.
The slope figure, in a unit you can picture
This listing rates the mower for 35%, which is rise over run — and nobody stands at the bottom of a bank and thinks in percent. As an angle that is about 19 degrees. The rating is measured on dry grass, driving straight up. Wet grass is harder, a bank at the very edge of the cutting area is harder, and a turn taken across the fall line is harder than either, so read the number as a ceiling rather than a specification of what it will manage in your garden on a damp morning.
How it compares with its own class
Against the 14 camera-navigated robot mowers in this corpus, rather than against a generic alternative:
| Measure | This one | Class median | Where it sits |
|---|---|---|---|
| Lawn size claimed | 8,611 sq ft | 7,260 sq ft | above the class median of 7260 sq ft |
| Cutting width | 7 in | 7.1 in | below the class median of 180.1 mm |
| Distance per full cut (derived) | 2.8 miles | 2.4 miles | above the class median of 12446 ft |
| Rated slope | 35% (19°) | 35% (19°) | the same as the class median |
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 8,611 sq ft, measured rather than estimated — and measured as mown area, not plot size.
- A stable lawn layout, where a wire laid once is not a nuisance — and it remains the most reliable boundary there is.
- Ground with real fall to it: 35% is about 19 degrees, which is a bank rather than a gentle rise.
- A lawn small enough that the mower is not driving a marathon to finish a cut.
Where it does not
- A lawn whose shape changes often, or a garden where a buried wire is a problem to lay and a problem to repair.
- A large lawn in a hurry — 7 in is a narrow deck, and the distance above scales inversely with it.
- Consistently wet or loose ground, where two-wheel drive is the usual thing to run out of.
- A lawn kept at a particular height, since this listing does not state what the cutting height adjusts to.
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, rated slope. It does not state a cutting height.
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 whether 8,611 sq ft is one lawn or several. Front and back joined by a path the mower must cross is the common case at this size, and it is the one that separates machines that manage a garden from machines that manage a rectangle. Whether yours can cross unmown ground, and whether it will find its way back, is not on any listing.
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. A perimeter wire is laid once and then it is done: reliable, dull, and a genuine nuisance if the lawn changes shape or a spade goes through it. Finding the break is the job nobody enjoys. Against that, it is a physical edge rather than a calculated one, and it does not stop working because the sky is cloudy.
Before you decide
Measure the lawn, do not estimate it
8,611 sq ft is a ceiling on mown grass, not on the plot. Beds, paths, the patio and the shed come off before the comparison is fair. 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.
Check the slope where it is steepest
This one is rated 35%, about 19 degrees, measured on dry grass driving straight up. The figure that matters is the worst few feet of your garden rather than its average, and wet grass moves the answer the wrong way, and without all-wheel drive the margin is thinner than the number suggests.
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.
