Main trade-off
Husqvarna Automower 420 iQ
It is less traction-focused than four-wheel-drive rivals.
Head-to-head
Choose 420 iQ for flexible EPOS or physical boundaries and tall grass settings or WR344 for a steeper four-wheel-drive lawn.
Before you choose
It exceeds 420 iQ's rating by 25 percentage points and remains 14 points below WR344's maximum.
What this is based on
70 - 45 = 25. 84 - 70 = 14. Interior ratings do not replace boundary-specific guidance.

Automower 420 iQ vs Landroid Vision Cloud 4WD WR344: compare lawn area, slopes, cutting height and installation needs before choosing your mower.
Choose 420 iQ for flexible EPOS or physical boundaries and tall grass settings or WR344 for a steeper four-wheel-drive lawn.
Winner by situation
It exceeds 420 iQ's rating by 25 percentage points and remains 14 points below WR344's maximum. 70 - 45 = 25. 84 - 70 = 14. Interior ratings do not replace boundary-specific guidance.
WR344's 3.54-inch ceiling is 0.21 inch short, while 420 iQ includes that target within its range. 3.75 - 3.54 = 0.21 inch. 420 iQ reaches 4 inches.
The 0.7-inch deck difference is modest compared with the 39-percentage-point gap in slope ratings. 9.4 - 8.7 = 0.7 inch. 0.7 ÷ 8.7 × 100 = 8.0%. 84 - 45 = 39 percentage points.
Husqvarna gives you an included reference station plus cloud EPOS where covered, and lists physical-wire operation with wire sold separately. WR344's Cloud RTK and visual localization call for a service-coverage check at the property.

Try your real numbers
The result checks hard limits only. Preferences stay out of the calculation.
Rated for 1 acre with systematic mowing, or 0.5 acre with irregular mowing, and 45% interior grade, with wire-free setup. Your input is 0.25 acre and 20% grade.
Rated for 1 acre and 84% interior grade, with wire-free setup. Your input is 0.25 acre and 20% grade.
The area check uses the published maximum without adding a reserve. Where a systematic mowing rating is shown, that pattern is required for the maximum area. Boundary slopes can have a lower limit than interior ground. Trees, gates and disconnected zones still need checking.

Husqvarna, 420 iQ
The one-acre member of Husqvarna's iQ line balances established support with wire-free EPOS mapping.

Worx, WR344
The one-acre WR344 pairs the 4WD chassis with a larger battery and cloud-based positioning.
Meaningful differences
| What changes | Husqvarna Automower 420 iQ | Worx Landroid Vision Cloud 4WD WR344 | Why it matters |
|---|---|---|---|
| Rated grass area | 1 acre | 1 acre | Both target a headline acre, but 420 iQ's 45% terrain limit and WR344's 84% four-wheel-drive claim serve very different hills. Measure the steepest work area and the edge slope separately before considering app convenience. |
| Cutting-height range | 1-4 inches | 1.57-3.54 inches | The selected height must sit within the exact US model's range. H variants can have different minimum heights from 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 | Husqvarna gives you an included reference station plus cloud EPOS where covered, and lists physical-wire operation with wire sold separately. WR344's Cloud RTK and visual localization call for a service-coverage check at the property. |
| Drive and interior climbing limit | Two-wheel drive, 45% grade | Four-wheel drive, 84% grade | Use a measured rise-over-run grade. Maximum interior climbing ratings do not establish the allowable slope beside a boundary, pond or drop. |
| Combined cutting width | 9.4 inches | 8.7 inches | Cutting width describes the grass swath, not body width or a guaranteed gate clearance. Turns, overlap and charging determine the real work rate. |
What you give up
Recommendation switch
Choose Husqvarna Automower 420 iQ. Both target a headline acre, but 420 iQ's 45% terrain limit and WR344's 84% four-wheel-drive claim serve very different hills. Measure the steepest work area and the edge slope separately before considering app convenience.
Choose Worx Landroid Vision Cloud 4WD WR344. Worx WR344 lists a 84% interior slope limit, while the other compared model stops at 45%. Boundary slopes, drops, wet traction and the rest of the installation still need separate checks.

The Husqvarna 1-4-inch height range accommodates both lower and taller cuts than WR344's 1.57-3.54 inches. Their deck widths are much closer, at 9.4 and 8.7 inches, so cutting height and terrain matter more than a small swath difference.
What the facts say
Useful conclusions from the current robotic lawn mowers comparison, followed by the checked facts used to reach them.
Only 4 of 56 models checked match every need here: “My mowable area is one acre or more”, “The lawn has sustained steep slopes”, and “My grass needs a cut above three inches”.
4 matching models from 56 checkedWorx Landroid Vision Cloud 4WD WR344 lists 1 acre for published lawn-area rating, 100% above Husqvarna Automower 420 iQ at 0.5 acre.
Match countThe count uses the current product-to-need assignments for “My mowable area is one acre or more”, “The lawn has sustained steep slopes”, and “My grass needs a cut above three inches”. A need with no documented match does not count.
Calculation noteThis compares the maker-rated lawn area. Slope, layout, obstacles and mowing frequency can reduce practical coverage. 47 of 56 models have comparable published figures for context.
