Few close matches: the list also allows a wider deck range, other duty classes and discontinued models, each labelled.
Chosen by stated rules, not opinion: same class, a deck within range of this one, the same kind of power and a compatible duty class, then the closest power, weight and price, with other makers preferred. Figures are the manufacturers’ published ones; nothing is estimated.

Fit uses the deck width plus 6 in for the discharge chute, because Kress doesn't publish an overall width — measure before buying if a gate is tight.
Work area is Kress's own rated maximum, converted from the 28,328 m² they publish. A robot rated below your lawn will not keep up with it.
Maximum slope is 40%, which is about 22°. Makers quote one or the other; they are the same figure, and 40% is not 40°.
Battery energy is voltage x amp-hours; run time depends on cut height, grass load and blade speed, so it isn't estimated here.
