How to read these numbers. Every specification here was taken from the product's own Amazon page on 2026-08-21 and normalised into the same units. A dash means the manufacturer does not publish that figure — we never estimate one to fill a table. We do not republish prices at all: Amazon changes them daily, so each mower shows the bracket we place it in and you tap through for the live figure.

Not published by the manufacturer on this listing: runtime, charge time, noise. Those rows show a dash rather than a guess.

Our verdict

This is not a domestic robot mower with a bigger battery; it is a modular yard system that happens to mow. Six acres is twenty times the coverage of most of this catalogue.

In depth

The Yarbo Pro is built around a modular chassis — the mower deck is one attachment in a four-season system. Dual 300W motors drive a 20-inch cutting width, the widest here by five inches, and the cutting height spans 0.8 to 4.0 inches, the broadest range in the catalogue. It weighs 215 lbs, so this is machinery, not an appliance. At flagship money it is aimed at smallholdings and estates rather than gardens.

What works

  • Six-acre coverage — twenty times most mowers here
  • 20-inch cutting width, the widest in the catalogue
  • 0.8 to 4.0-inch cutting height range, also the widest
  • 70% gradient rating and IPX6 sealing
  • Modular platform covering more than mowing

What doesn't

  • By some distance the most expensive machine here
  • 215 lbs is machinery, with the storage and handling that implies
  • Overkill for any normal domestic lawn
  • A thin ownership record for the money

Buy it if

A smallholding, estate or paddock measured in acres rather than square feet.

Look elsewhere if

Any normal domestic garden. Nothing about this machine is sized for one.

Common questions

Will it handle my lawn size?

This model is rated to 6 acres. Manufacturer coverage figures assume dry grass, daily mowing and a reasonably open shape — take off roughly 15% for a lawn with trees, narrow passages or a wet climate.

How steep a slope can it manage?

Rated to 70% — about 35 degrees. That figure is for dry grass. If your steepest bank is close to this number, treat the model as out of range rather than borderline.

What does setup involve?

Boundary type: Wire-free (app mapping). No perimeter wire. The lawn is mapped from the app, which typically takes an afternoon including placing the antenna.

How often do the blades need replacing?

Roughly every four to six weeks of daily mowing. Dull blades tear grass instead of cutting it, which is the usual cause of brown tips. Replacement blades for this model cost a few dollars a set.

Replacement blades and mounts for this model are on our accessories page.
