Match the machine to your lawn size
Bigger lawns need more working-area rating, battery and often multiple zones. Here's what actually keeps up on a large property.
Tree cover changes everything
Satellite mowers fail under a canopy — this is where LiDAR earns its price. If your yard is shaded or wooded, start here.

Know the real running cost
Electricity, battery life and total cost of ownership. The numbers are smaller than you think — and they usually beat a weekly service within a few years.

Frequently asked
How do I know what size robot mower I need?
Match the mower's working-area rating to your real mowable square footage (the grass only — minus house, beds and driveway). Big open lawns want a high-capacity machine or a fleet; most suburban yards are covered by a mid-size model. Our free lawn check measures it from satellite.
Which robot mower is best for a yard with lots of trees?
A LiDAR mower — the Mammotion LUBA 3. Satellite/RTK mowers need a clear view of the sky, which a canopy blocks, so they drift or stop. LiDAR maps the physical world instead and keeps mowing under cover. See the wooded-yards pick guide above.
Are robot mowers expensive to run?
No — most cost only a few dollars a month in electricity, and the battery often outlasts the mower on a small lawn. Over a few years they typically beat a weekly lawn service. The cost and battery guides above run the full math.
