What robot mower can climb my yard?

If your bank rises 4 ft over 10 ft, that's a 40% slope (about 22°). We'd compare that with each mower's published maximum, and leave extra margin if the steep part is at the edge of your lawn.

How to measure with a phone
If you've got a phone, lay a straight board on your bank. Open the phone's level app and set it on the board. Read the angle in degrees, or the percent if the app shows percent. The other way: run a 10 ft string line from the high point to the low point, pull it level, and measure the vertical gap with a tape. That gap in feet, divided by 10, times 100, is the percent. A 4 ft gap is 40%.
Converter
Percent, degrees, and rise per 10 ft are the same slope on your bank. Degrees are the arctangent of percent divided by 100. Rise over 10 ft is 10 ft times percent divided by 100.
40.0% · 21.8° · 4 ft over 10 ft
The degrees and the rise come from the percent you entered. Rise is 10 ft times that percent, divided by 100. Degrees are the arctangent of the percent divided by 100.

Printed conversions
These degrees are worked out from the percent. They're not a second published rating. A model is listed when its published maximum is at least that percent. Where a boundary figure is lower, that maximum is the interior, and the boundary may not cover the same percent on your lawn.

Makers usually publish one maximum slope and don't say whether it applies in the middle of your lawn or at the edge. When a model also gives a lower figure for the edge, that's the one to use there. If your bank runs into a bed or a fence, we'd leave some margin, because edges are usually harder.

The Worx WR340 is rated 30%. We'd skip it when your bank is steeper than that. The WR344 is the 84% model in that family. Worx Landroid Vision Cloud review.
Questions
What does 80% slope mean?
80% is a rise of 8 ft over 10 ft. Dreame prints 38.7° and the LUBA 3 AWD 3000 prints 38.6°. If a model doesn't publish degrees, we don't invent one.
Why do some mowers list two slopes?
Husqvarna's iQ pages put 15% at the boundary beside a higher interior figure. If your steep spot is the edge, the boundary number is the one that matters.
Is 40% steep for a robot mower?
40% is 4 ft over 10 ft. That's above the WR340's 30% and under the 45% i210 figure and the 80% and 84% models.
