Cutting-height range is easy to overlook until the mower cannot match the height your turf requires. The minimum and maximum settings matter more than the number of adjustment steps.
What actually drives the answer
Grass species and climate determine the practical mowing-height window. A mower that cannot reach the upper end you need during heat or drought can be a poor fit even if every navigation feature is excellent.
Where buyers get tripped up
Frequent robot mowing means very small clippings, but that does not eliminate the need for a correct target height. Cutting too low can stress turf; buying a mower with the wrong range creates a structural mismatch.
How to make the decision
Identify the recommended mowing height for your turf and local conditions, then require the robot’s adjustable range to cover it with margin. App-controlled height is convenient but secondary to having the right physical range.
How we research robot mowers
We normalize manufacturer specifications around the buying constraints that actually change the decision: recommended mowing area, navigation architecture, slope capability, cutting-height range, obstacle sensing, charging behavior, multi-zone support, warranty, parts availability, and current pricing. We give more weight to property fit than to feature count.
Prices, specifications, firmware, and configuration-driven features can change. Check the current manufacturer page and local requirements before buying or installing equipment.
