Will a robot mower fit through your gate?

We checked 47 US models. 20 have a clear published minimum passage width, from 21.7 to 39.37 inches. 16 have unclear or conflicting figures, and we found none for 11.

These figures aren't all the same kind of number. Some are product-page claims about the narrowest gap a mower fits through. Others are setup guidance from a manual or support article, which can be more cautious. We show the source so you can see which is which. A figure here is the maker's statement; we don't test mowers ourselves. Measure your narrowest gate at ground level, and allow room for the mower to turn into it.

Check a 36-inch passage with your yard details. You can also see the multiple-zones example or read how the rules work.

Scroll sideways to compare passage width, body width and the 36-inch result.

Each row is one model. A value appears only when its status is verified, meaning a manufacturer source states it clearly; we don't measure it ourselves. ambiguous means the sources are unclear or conflict, and missing means we found nothing in the manufacturer sources we checked. Both leave the value blank. Each fact lists its source, source type and retrieval date. Mammotion manuals are PDF links on Zoho WorkDrive, listed on Mammotion's support site.
