FireFly’s current specification sheet lists coverage of 20–25 acres (8–10 hectares) per charge; the upper figure is roughly 18.9 NFL football fields, the comparison behind the 2023 headline. That acreage is a manufacturer specification, not a guaranteed result or an independently verified test.
What does “19 football fields” mean?
New Atlas used 18.9 NFL football fields to illustrate 25 acres in its July 25, 2023 article. The field comparison is a way to picture the area, not a standardized mower rating. FireFly’s current specification is expressed in acres: 20–25 acres (8–10 hectares) per charge, with actual output varying by use conditions. New Atlas’s 2023 report supplies the football-field analogy; FireFly’s 2026 specification sheet provides the current acreage range.
What the AMP-L100 specifications say
FireFly describes the AMP-L100 as an electric autonomous platform intended for large turf areas, including golf fairways. Its manufacturer-listed specifications are:
| Specification | FireFly-listed figure |
|---|---|
| Cutting width | 100 inches (2.54 m) |
| Cutting units | Five 7-inch reels, each 22 inches wide |
| Battery | 48V, 35.3kWh, 690Ah lithium iron phosphate (LFP) |
| Coverage per charge | 20–25 acres (8–10 hectares); actual results vary with conditions |
| Runtime per charge | 4–6 hours |
| Mowing speed | Up to 6 mph |
FireFly lists optional fairway reel configurations with 7, 8, 11, or 14 blades. Reel choice affects the cutting setup, so buyers should confirm the currently available configuration and its suitability for the desired turf finish. The machine’s navigation and control features include dual-antenna RTK-corrected GPS guidance, 3D LiDAR object detection, cloud-based FireLink, and customizable path planning, according to the manufacturer specification sheet.

Autonomous mowing does not mean self-charging
The AMP-L100 can mow and navigate autonomously, but FireFly’s current FAQ says it does not have an auto-docking feature. An operator must bring it to a charger. FireFly says it can be driven from its rear operator platform for transport and charged where compatible equipment is installed. That distinction matters for scheduling: autonomous mowing reduces the need for an operator at the controls during mowing, but the charging move still needs to be planned. See the AMP Mowers product information and FAQ.
Why acreage per charge varies
The 20–25-acre figure is not a promise that every site will get the maximum. FireFly says productivity depends on field conditions, grass type, mowing frequency, surface smoothness, and field size. Those factors affect how much area a machine can cover during a charge, so an estimate for a particular property should be based on its turf and operating plan rather than the headline comparison alone.

Where FireFly says the mower is being used
FireFly reported that four AMP mowers maintained 60 acres of fairways over the four weeks surrounding the 2024 Black Desert Championship. That is a company-reported deployment, not an independent performance assessment. In its announcement, co-founder and Chief Technology Officer Steve Aposhian said: “It validates that the technology we have built into AMP will revolutionize the industry, while also highlighting that this is the only autonomous mower on the market currently capable of taking on such a task.” The “only” claim is the executive’s promotional statement; the available reporting does not independently establish it. FireFly also announced a 2026 expansion across Concert Golf Partners properties following an initial deployment at Heathrow Legacy Club, and described those AMP-L100 deployments as capable of up to 25 acres per charge with a 100-inch swath. Those examples show reported commercial use, not proof of savings or suitability at every property. Sources: FireFly Automatix and its company announcements.
What a golf-course or turf operator should verify
Coverage is only one part of deciding whether a large autonomous reel mower fits a site. Before comparing it with other equipment, ask the manufacturer about:
- Whether the property’s acreage, grass, terrain, surface condition, and mowing frequency suit the AMP-L100.
- The required reel configuration and expected finish for the site’s turf.
- Charger placement, electrical service, and how staff will move the mower to charging.
- Site mapping, exclusion zones, navigation setup, and operating procedures.
- Service coverage, warranty details, delivery timing, and current purchase price.
FireFly does not publish a current price or delivery schedule in the reviewed product information. Its AMP mower contact page invites inquiries about site fit, demonstrations, delivery slots, and pricing. No comparable independent head-to-head results or current price are established in the cited material, so a ranking against other mowers would require additional evidence.
