9 models fit, out of 56 checkedPicked for one job
A one-acre lawn needs capacity and navigation you can trust
Top pick
Segway Navimow X430
A one-acre rating, 4WD and an unusually broad cut range come together in the Segway Navimow X430. If local dealer support matters more to you than maximum slope capability, go with the Husqvarna 420 iQ.
Why it suits this job
- Measured lawn area
- Charging and mowing schedule
- The catch
- A small, flat lawn gives you little reason to carry its capability and footprint.
- Go with Husqvarna Automower 420 iQ if
- Large, conventional lawns close to a Husqvarna servicing dealer

Show the facts and the math
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 “Several separate mowing zones are what I need”. 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. The median draws on the 47 of 56 models that publish comparable figures.
