What size robot lawn mower do I need? Acreage and capacity

How models qualify

US-listed autonomous or modular models with active or preorder status and published capacity from 0.5 to under 1 acre.

Check whether the stated half-acre capacity assumes a near-continuous schedule. A larger-capacity model can provide useful margin when narrow passages, slopes, or weather reduce available mowing time. Compare one-acre models if your lawn is close to the limit.
