Start with the honest question: is it worth it?
The full cost-vs-service math, the time you get back, the hidden costs nobody mentions — and the lawns where a robot is NOT the right answer.
What it costs to run, month to month
kWh per mow, your electric rate and the real monthly number — most lawns cost just a few dollars a month in electricity.
The battery — the one big wear item
Real cycle math by lawn size: on a small lawn the battery can outlast the mower; on a big one plan for about 5 years. Here's how to know which you are.
The alternative: what a lawn service really costs
Weekly service vs a robot that cuts daily — the payback math, plus why little-and-often mowing grows a thicker lawn while it saves you money.
Winter runs the same math
The same honest-cost approach, applied to snow: a robotic snow blower against a plow contract or per-storm plowing, with payback measured in seasons.

Frequently asked
How much does a robot mower cost up front?
Most residential machines run about $1,400 to $3,300 depending on lawn size and terrain — small-yard models at the low end, flagship AWD machines at the top. Commercial-class robots for 3–6 acres run roughly $5,500–$7,000. Our free lawn check tells you which class your yard actually needs before you spend anything.
What does a robot mower cost to run?
A few dollars a month in electricity for most lawns, plus blades every 4–6 weeks as a small consumable cost. There's no gas, no oil, no tune-ups. The running-cost guide above has the kWh math for your own electric rate.
When does a robot mower pay for itself?
Against a typical weekly lawn service, usually within a few seasons — and the robot cuts daily instead of weekly, which grows a thicker lawn along the way. The worth-it guide above runs the full payback math, including the lawns where the answer is honestly no.
