How to choose
1. Measure the grass, not the plot
A half-acre lot often has a quarter acre of lawn once you remove the house, drive and beds. Rated areas are maximums, so leave some headroom. Our lawn measuring guide shows three quick ways.
2. Find your steepest slope
Ratings range from 18° (about 32%) on the eufy E15 to 40° (84%) on the Navimow X4 and WORX Vision 4WD. The slope guide explains how to measure it with a phone.
3. Match the navigation to your sky
RTK mowers need a clear view of the sky. LiDAR and vision mowers don't, which matters under big trees or between tall buildings. Read RTK vs LiDAR vs vision.
Then try your own numbers in the fit calculator.
