🌍 The Zippy Movement
Every robot mower is one less gas mower.
Register your robot — any brand, bought anywhere — and it joins the count: the gas our members' robots keep from being burned, the CO₂ that never reaches the air, and the Saturdays handed back. Every season.

Any brand. Then answer one question: what did this robot replace?
You're in the count
My Mower shows your own season — gas, CO₂ and hours — beside the whole movement's.
The answers we ask about: A gas push mower · A gas self-propelled mower · A riding mower or lawn tractor · A gas zero-turn · A lawn service (a crew mowed it) · A battery mower · Nothing — a new lawn, or it wasn't mowed.
How we count it
Every number, with its assumption
- Per season: one mow a week through the local mowing season (34 weeks in Pennsylvania, longer further south).
- Gas: what the replaced machine burns over the time it takes to mow that lawn — the same machine figures as our ROI calculator.
- Hours back: time on the mower plus 10 minutes of setup and cleanup per mow, only for owners who mowed it themselves.
- CO₂: U.S. EPA: burning a gallon of gasoline makes 8,887 grams (19.6 lb) of CO₂. It counts the gasoline not burned, not the electricity the robots use.
- Lawn size: the lawn the owner mapped; half an acre when there's no map yet.
- Owners who haven't told us what their robot replaced count as the typical gas mower for their lawn's size. Gas mowers retired counts only the owners who told us.
- A lawn service counts as a crew zero-turn's gas over the lawn, not the truck that brought it.
Questions
Do I have to have bought my robot mower from Zippy Lawnz?
No. Any robot mower counts, whatever the brand and wherever you bought it. Create a free account, register it, and tell us what it replaced — that's how it joins the count.
What exactly do you count?
The gas the machine your robot replaced would have burned mowing your lawn, the CO₂ that gas would have made, and the hours you no longer spend mowing — per season, using the same machine figures as our ROI calculator. Every assumption is listed on this page.
Does it count the electricity the robots use?
No — it counts the gasoline not burned, and says so. A robot mower's season of charging is usually a few dollars of electricity; your My Mower page shows your own running cost.
Is my address or name shown anywhere?
No. This page shows totals only. States with fewer than 3 households are folded into "Other", so no one is singled out.
Why is it 'every season' instead of a running total?
Because it's true every year a robot keeps mowing. A clock that ticked all winter would count mowing that never happened.
