One brand at a time: the models a maker currently sells in the US, with the lawn size, slope, navigation and price it publishes for each. Two brands so far, Husqvarna and Worx.

Why compare models within one brand
A maker's range looks like a ladder, but the steps are not always where the names suggest, and the deciding detail is often in the manual rather than on the product page. Worx's product pages rate the Landroid Vision Cloud 4WD models for 40-degree slopes; the manuals add that with the Cut to Zero edge module, which the models on sale have, Worx does not recommend slopes over 15 degrees. Husqvarna rates its iQ models twice, for a systematic and for an irregular lawn. Each brand guide puts the maker's own figures side by side, with the date we checked them.
