Which model for which lawn
For each lawn size, the Roborock model the sizer puts first in each market: the smallest limit that still covers the lawn with its margin. The lawn is of typical shape (× 1.35), mowed at any time, on a gentle 15% slope. The table ranks the 3 Roborock models in the Botsize dataset only.

Tight means the rating covers the lawn but not the margin. Your own lawn may differ in shape, slope and hours: the mower sizer checks it with your numbers, and the methodology states the rules.
