The catch
Yarbo Mower Pro
An ordinary suburban lawn doesn't warrant the price, storage footprint and setup burden.
Side by side
Yarbo comes into play once measured grass runs well past two acres, or when the modular yard platform is worth something beyond mowing. For a moderate two-acre lawn the 440 iQ is easier to own, particularly if a servicing dealer is nearby.
Before you buy
Yarbo Mower Pro is the better match for “The terrain is rough, rutted or otherwise uneven” and “Long steep slopes run across the lawn”. Husqvarna Automower 440 iQ is the better match for “I want a local dealer to handle repairs” and “Several separate mowing zones are what I need”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.

The catch
For rough 40-degree banks, a two-wheel layout is not the first choice.

A modular tracked machine set against a conventional two-acre robotic mower.
This one comes down to published area and published slope first, then to the limits of your own setup.
Which one fits
On changing terrain, it gets more traction from driven front wheels or an articulating chassis.
The mower line it belongs to has an established servicing-dealer channel.
Yarbo Mower Pro lists “Modular direct system” for ownership model, while Husqvarna Automower 440 iQ lists “Established dealer network”. Confirm the exact model and what comes in the box. This row covers the selected offer only. Other versions sold under the same family name may differ.
It can cut lower than the common two-inch floor.
It follows a mapped systematic route and does not wander randomly.
Multiple mapped work areas and connecting routes are supported in its app.

5 of the 56 robotic lawn mowers checked fit this need. Husqvarna Automower 440 iQ makes the cut. Yarbo Mower Pro does not.
The count filters every model in the current category for a strong or useful fit on this single need.
2 of the 56 robotic lawn mowers checked handle both “I have one acre or more that can be mowed” and “I want a local dealer to handle repairs”. Husqvarna Automower 440 iQ makes the cut. Yarbo Mower Pro does not.
You can reproduce the count by filtering the current category for models with a strong or useful fit on both needs.
Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
Its rating covers 6 acre and 70% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Its rating covers 2 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.

Yarbo, Mower Pro
This modular tracked yard robot is meant for properties far larger than ordinary robot-mower acreage, and for severe transitions.

Husqvarna, 440 iQ
Broad properties that put dealer support ahead of extreme-slope hardware suit this two-acre EPOS mower.

Trade-offs
By the numbers
What we found across the robotic lawn mowers we compare, plus the checked facts behind each finding.
None of the 56 models checked meets all of “I have one acre or more that can be mowed”, “The terrain is rough, rutted or otherwise uneven”, and “I want a local dealer to handle repairs”, so the pick goes to the closest practical compromise.
