The catch
Husqvarna Automower 420 iQ
Four-wheel-drive rivals put more emphasis on traction.
Side by side
Husqvarna Automower 420 iQ vs Worx Landroid Vision Cloud 4WD WR344: 420 iQ can run on a wire, and WR344 handles steeper interior ground
Quick verdict
Flexible EPOS or physical boundaries and tall grass settings favor 420 iQ. A steeper lawn that calls for four-wheel drive favors WR344.
Before you buy
Why, and what it costs you
Only the published Worx terrain envelope fits a 70% slope
It goes 25 percentage points past 420 iQ's rating and stays 14 points below WR344's maximum.
Where this comes from
70 - 45 = 25 and 84 - 70 = 14. Boundary-specific guidance is not replaced by interior ratings.
The catch
Worx Landroid Vision Cloud 4WD WR344
Across one acre, any weak cloud-RTK area matters more.

WR344's range does not take in a 3.75-inch seasonal cut
The 3.54-inch ceiling on WR344 falls 0.21 inch short, whereas 420 iQ includes that target in its range. 3.75 - 3.54 = 0.21 inch. 420 iQ reaches 4 inches.

Next to the 39-percentage-point gap in slope ratings, the 0.7-inch deck difference is modest. 9.4 - 8.7 = 0.7 inch. 0.7 ÷ 8.7 × 100 = 8.0%. 84 - 45 = 39 percentage points.

Plug in your numbers
Can either mower handle your yard?
This checks hard limits only. Personal preferences are left out of the math.
Husqvarna Automower 420 iQ
Works with your numbersIts rating covers 1 acre mowing systematically (0.5 acre mowing irregularly) and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Worx Landroid Vision Cloud 4WD WR344
Works with your numbersIts rating covers 1 acre and 84% 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.
Option A
Husqvarna, 420 iQ
Automower 420 iQ
In Husqvarna's iQ line, the one-acre model pairs established support with wire-free EPOS mapping.
- Best for

- Typical mowing of 84 minutes and typical charging of 54 minutes are listed in the US specification.
- Listed are EPOS virtual boundaries and a supported physical-wire option.
Option B

Facts we checked
- One acre is the Worx rating for the WR344.
- An 8 Ah battery and 8.7-inch cut are listed in the manual.

Spec by spec
Where they really differ
| Spec | Husqvarna Automower 420 iQ | Worx Landroid Vision Cloud 4WD WR344 | In practice |
|---|---|---|---|
| Rated grass area | 1 acre | 1 acre | Both headline an acre, yet the 420 iQ's 45% terrain limit and the WR344's 84% four-wheel-drive claim suit very different hills. Before you think about app convenience, measure the steepest work area and the edge slope separately. |
| Cutting-height range | 1-4 inches | 1.57-3.54 inches | Your chosen height has to fall inside the range of the exact US model. The minimum height of H variants can differ from that of a larger standard model. |
| Positioning and installation | EPOS with an included reference station or cloud service where covered, physical wire also supported | Cloud RTK, stereo vision and VSLAM | The Husqvarna comes with a reference station and offers cloud EPOS where covered. It also lists physical-wire operation, with the wire sold separately. The WR344 uses Cloud RTK and visual localization, so check service coverage at the property. |
| Drive and interior climbing limit | Two-wheel drive, 45% grade | Four-wheel drive, 84% grade | Work from a measured rise-over-run grade. A maximum interior climbing rating does not establish the allowable slope beside a boundary, pond or drop. |
| Combined cutting width | 9.4 inches | 8.7 inches | Cutting width is the grass swath. It says nothing about body width or a guaranteed gate clearance. The real work rate comes down to turns, overlap and charging. |
Trade-offs
What each pick costs you
With Husqvarna Automower 420 iQ
- How much it is worth to you depends in part on local dealer coverage and installation help.
With Worx Landroid Vision Cloud 4WD WR344
- Check the long list of specifications carefully against the accessories that are installed.
Change of plan
When the answer changes
Your cutting settings have to reach 4 inches
Go with Husqvarna Automower 420 iQ. Both headline an acre, yet the 420 iQ's 45% terrain limit and the WR344's 84% four-wheel-drive claim suit very different hills. Before you think about app convenience, measure the steepest work area and the edge slope separately.
Your measured interior slope is over 45% but no steeper than 84% grade
Go with Worx Landroid Vision Cloud 4WD WR344. The interior slope limit listed for Worx WR344 is 84%, while the other compared model stops at 45%. Boundary slopes, drops, wet traction and the rest of the installation still have to be checked separately.
Decision guide
How to decide
Go with 420 iQ for flexible EPOS or physical boundaries and tall grass settings. Go with WR344 for a steeper lawn that calls for four-wheel drive.
Begin with your lawn and cutting needs
Both headline an acre, yet the 420 iQ's 45% terrain limit and the WR344's 84% four-wheel-drive claim suit very different hills. Before you think about app convenience, measure the steepest work area and the edge slope separately.
Look at navigation and the path through your yard
The Husqvarna comes with a reference station and offers cloud EPOS where covered. It also lists physical-wire operation, with the wire sold separately. The WR344 uses Cloud RTK and visual localization, so check service coverage at the property.
Think through boundaries, upkeep and seasonal use
Husqvarna's 1-4-inch height range handles both lower and taller cuts than the 1.57-3.54 inches of the WR344. Deck widths are much closer, at 9.4 and 8.7 inches, so cutting height and terrain count for more than a small difference in swath.
What this page can’t tell you
- These area, grade, passage and runtime figures are manufacturer claims. We did not run real-world mowing tests.
- Follow the boundary clearances and safety instructions in the installation manual. Keep people and animals clear of blades while they run.
- Headroom in the mapped area does not promise a finish time. Grass growth, weather, obstacles, allowed operating hours and charging all change the outcome.

How we countedThe count uses each product's current fit ratings for “I have one acre or more that can be mowed”, “Long steep slopes run across the lawn”, and “My grass has to be cut higher than three inches”. A need with no documented match is not counted.
How we calculatedFigures are the lawn area the maker rates it for. Slopes, layout, obstacles and how often it mows can shrink the area it really covers. For context, 47 of 56 models publish comparable figures.
