Firefly Automatix Autonomous Mega-Mowers (2026): Sod Farms & Large-Acre Turf

Last updated July 2, 2026 · MowScout Editorial

Most of the commercial robot mowers we cover are, in the grand scheme, small: a 27-inch fairway robot, a 41-inch turf unit, a stand-on autonomous deck. FireFly Automatix builds something else entirely — the highest-throughput "mega-mower" class in autonomous turf, machines that cut a swath as wide as a small car is long and clear 20-plus acres between charges. This is the platform you research when the unit of work isn't a lawn or even a single field, but a sod farm, a whole-course fairway fleet, or a stadium-complex worth of open turf. It is real, it is shipping, and it is genuinely citeable — but it is also, honestly, a narrower fit for the typical MowScout reader than almost anything else in our catalog. This page is here to explain the machine accurately, flag exactly who it's for, and route everyone else back to the right tier.

The one-paragraph version. FireFly Automatix (Salt Lake City, UT; founded 2010; now doing business as FireFly Robotics) makes all-electric autonomous "AMP" mowers led by the AMP-L100: a ~100-inch cut across five reel gangs, up to ~25 acres per charge, roughly 6–7 acres per hour, on a 48-volt, 35 kWh lithium-iron-phosphate (LFP) pack, navigated by RTK-GNSS + LiDAR + cameras with an autonomy lineage that began with ASI. Its fleet has mowed 75,000+ acres autonomously, with 770+ machines in service worldwide. The company filed a ~$25M Nasdaq IPO (ticker FFLY) and then withdrew it in March 2026 — a scale signal wrapped in a real financial-risk signal. Target buyers: sod/turf farms, golf fairways, sports fields, and large open grounds — not homeowners.

How to read this page. MowScout is spec-verified and data-driven, not hands-on. We have not operated a FireFly machine. Every spec, rate, fleet figure, and financial number below is sourced (see the list at the end) and traceable. There is no consumer price — FireFly sells business-to-business by dealer/direct quote, so treat every figure as an estimate and request a current quote before budgeting.

Disclosure: This is a business-to-business, lead-generation overview, not a consumer-affiliate one. There are no "check price" deal boxes and no affiliate links here, because FireFly does not sell that way. Where MowScout has or develops a referral relationship with a dealer or manufacturer, we disclose it, and it never changes how we describe a platform. See our disclosure policy.

Why FireFly is a category of its own

The commercial robot-mower market sorts, roughly, into tiers by cut width and coverage. Residential flagships cover an acre or so. Mid-tier commercial robots — Husqvarna's CEORA, ECHO Robotics' turf units — cut two to three-and-a-half feet and cover a handful of acres a day. FireFly is the tier above all of them: a 100-inch cut is nearly four times the width of a CEORA and more than double ECHO's widest, and up to ~25 acres per charge is a different order of magnitude than "six acres per 24 hours."

That width isn't a spec-sheet flex; it's the whole thesis. FireFly grew out of the sod-farm world — founder Steve Aposhian came from a turf-farming family and engineered harvesting equipment before turning the same electric-drive and automation know-how toward mowing. On a sod farm you are mowing enormous, dead-flat, obstacle-light rectangles on a relentless schedule, and the economics reward the widest, fastest, most tireless machine you can field. Everything about FireFly's design — the multi-gang reel, the big LFP pack, the autonomous route planning — follows from optimizing that job first, then extending it to golf fairways and sports turf that share the "large, open, repetitive" profile.

So the honest one-line positioning: FireFly is not competing with the mid-tier robots; it plays above them. It is the mega-mower.

The AMP-L100: the specs behind the "mega" claim

The flagship autonomous product is the AMP-L100 (the "L100" — evolved from the machine FireFly first showed as the M100-AV in 2023). Verified specifications from FireFly's own materials:

Two honesty notes on the numbers. First, coverage: FireFly's marketing "19 football fields on a charge" is the 25-acre ceiling, which pencils to about 18.9 NFL fields — real, but a best-case figure on ideal turf. Second, productivity: the spec sheet says ~6 acres per hour and early press said up to ~7, but FireFly's own "75,000 acres" retrospective reports a 4.4 ac/hr average across live golf deployments. We cite both; the lower number is the one to plan against.

The M220-AV and the sod-farm heritage

The AMP-L100 is the golf-and-sports face of the company, but the M-series is where the mega-mower story started. The M220-AV is a 22-foot-wide (264"), hybrid diesel-electric autonomous field mower built specifically for turfgrass production — a machine so wide it is measured in feet, not inches. FireFly premiered it in 2023 and delivered the first pilot production unit to Prime Sod in Kopperl, Texas, in April 2023. Alongside the mowers sits the legacy PATH line of electric turfgrass harvesters, the automation heritage the whole company was built on.

The takeaway for a buyer: FireFly isn't a startup that bolted autonomy onto a consumer mower. It is a sod-equipment manufacturer that has been building electric-drive, automated turf machines for over a decade and extended that expertise into fully autonomous mowing. That heritage is the single best reason to take the platform seriously — and the reason its natural home is agriculture-adjacent large-acre turf.

The autonomy stack: LiDAR + cameras + RTK-GNSS, with ASI roots

FireFly's autonomy is a sensor-fusion stack, not a single trick. RTK-corrected GNSS with dual antennas gives centimeter-class positioning and lets operators define fields and virtual boundaries in software; LiDAR provides obstacle detection out to roughly 40–50 feet; and cameras add classification and let a remote operator watch the feed. Because these machines run big, remote acreage, FireFly bakes in Starlink connectivity so a unit stays supervised even where cellular is weak.

The lineage matters and is worth citing honestly. FireFly's first autonomous mower, the M220, was automated through a 2018 partnership with Autonomous Solutions, Inc. (ASI) — a fellow Utah robotics firm — using ASI's Mobius command-and-control platform, which plans efficient coverage routes and manages speed, steering, turning, braking, obstacle detection, and blade height. FireFly has since built out its own AMP autonomy software with named features shown ahead of GCSAA 2026: Path Linking (continuous mowing across multiple areas), SmartStart (drop it anywhere; it drives to the start point), Exclusion Zones (permanent no-go areas for bunkers, water, native vegetation), and Auto Sectioning, with vision-based small-object detection and verticutting on the roadmap. The accurate framing: the autonomy heritage was built with ASI, and FireFly has matured it into an in-house stack.

All-electric LFP: the powertrain and charging math

The AMP-L100 is all-electric on an LFP chemistry — a deliberate choice for this duty cycle. Lithium-iron-phosphate trades some energy density for cycle life and thermal safety, and FireFly rates the pack at roughly 5,000 charge cycles before falling to 80% capacity. For a machine expected to charge daily for years on a sod farm or a golf course, cycle life and fire-safety matter more than shaving weight, so LFP is the right call.

The operational math: a 35 kWh pack delivers 20–25 acres, then refills in about 2.5 hours on the fast charger. On a golf course that maps to overnight fairway work with a midday top-up; on a sod farm it maps to shift-based coverage with scheduled charging windows. The all-electric drivetrain also brings the quiet, zero-tailpipe-emissions profile that makes overnight and near-neighbor mowing viable — the same reason superintendents like autonomous turf robots generally, here at mega scale.

Who it's for — buy-if / skip-if

Buy-if (the honest target buyer):

• Sod / turf farms mowing large contiguous rectangles on a relentless schedule — the home use case, and where the M-series width earns its keep.
• Golf courses wanting to automate whole-course fairway mowing with one or a few machines instead of a gang-mower crew — the AMP-L100's flagship market (65+ clubs, 40,000+ fairways mowed).
• Sports fields and multi-field complexes with large, open, low-obstacle turf — see our commercial robot mowers for sports fields guide.
• Large open grounds — corporate campuses, airfields, municipal parks with big contiguous acreage and the budget for an industrial capital purchase.

Skip-if:

• You have a residential lawn, even a big one — this is wildly oversized; use the configurator.
• Your turf is small, tight, obstacle-dense, or heavily shaded — a 100-inch reel and a sky-dependent RTK stack are the wrong tools; a mid-tier or vision-AI robot fits better.
• You need a published price and a fast, low-commitment buy — this is a negotiated capital purchase, not a checkout.
• Your acreage is better served by a solar-vegetation platform — for panel arrays, see commercial robot mowers for solar farms.

The scale signal: 75,000+ acres and 770+ machines

FireFly's strongest credibility claim is operating history at scale. As of its milestone announcement (May 2026), FireFly's autonomous mowers had cut more than 75,000 acres across live golf courses — equivalent to 40,000+ fairways and more than 3.2 billion square feet — across 65+ clubs in over half of U.S. states plus Puerto Rico, Canada, Mexico, and an Australia pilot. That is not a demo reel; it is fleet-years of real turf.

Across all product lines, FireFly reported more than 770 machines in service worldwide (PATH harvesters, AMPs, and M220s combined) as of June 30, 2025, up from 76 machines in 2016 — roughly a 31.5% CAGR — sold to customers in the U.S., Australia, the U.K., Brazil, Canada, South Africa, and Mexico. This is the honest counterweight to "spec-verified, not hands-on": we haven't run the machine, but a fleet this large and this well-traveled is a meaningful independent signal that the platform works in the field.

The ~$25M Nasdaq IPO filing (FFLY) — and why it was withdrawn

Here the always-current discipline earns its keep. The FireFly Automatix IPO is frequently cited as a bullish "the category is institutionalizing" data point — and the filing is real and citeable — but the outcome is not what most write-ups still say.

• FireFly filed confidentially in April 2025 and publicly (Form S-1) in October 2025, targeting a Nasdaq listing under ticker FFLY — about $25 million (roughly 4.5 million shares at $4.50–$6.50), with Roth Capital and Lake Street leading and Chardan as co-manager.
• The filing disclosed a Salt Lake City company with ~$44–48 million trailing revenue (12 months ended mid-2025) — but also net losses every year since 2010, including roughly $13.5M for FY2024 and ~$2.4M in Q1 2025, an accumulated deficit near $79M, and a total stockholders' deficit near $58M as of March 31, 2025. It described itself candidly as not yet profitable, facing declining gross margins, rising costs, and customer hesitancy.
• On March 16, 2026, FireFly withdrew the IPO amid market headwinds. As of mid-2026, FFLY is not a traded stock.

The honest reading: the S-1 is a scale signal (real revenue, 770+ machines, a decade-plus operating record) and a financial-risk signal (persistent losses, a stockholders' deficit, a pulled offering). A pre-profit hardware company in a capital-intensive category is exactly where you'd want a buyer to weigh vendor durability before committing to a six-figure fleet — so we flag it rather than bury it. It does not diminish the machine; it's a reason to ask hard questions about service continuity in your quote conversation.

How FireFly compares to ECHO Robotics and Husqvarna CEORA

Read across that table and the positioning is unmistakable. CEORA is the elegant answer for a golf course or a sports field — wire-free EPOS boundaries, ~$32,800 dealer-quote, a machine a single superintendent adopts. ECHO scales that idea to bigger contiguous turf and multi-mower fleets. FireFly is the answer when even those feel small — when you are mowing a sod farm, an entire course's fairways with one or two machines, or a stadium complex, and you want maximum acres per machine per hour. They are complementary tiers, not rivals: most buyers who genuinely need FireFly would find a CEORA underpowered for the job, and most buyers happy with a CEORA would find a FireFly oversized and over-budget.

The honest fit for MowScout readers — and the prosumer bridge

We'll be direct: most people who land here do not need a FireFly. It is an ag-adjacent, large-acre, industrial mega-mower — fascinating, real, and worth documenting as the ceiling of the autonomous-mowing market, but relevant to a small slice of our audience (turf-farm operators, golf and stadium grounds managers, large-grounds facilities teams).

If you arrived because your property is large but not commercial — a multi-acre estate, an HOA common green, a campus lawn — you are in the prosumer bridge, and the smart move is to price the top of the residential catalog before you ever request an industrial quote. The consumer flagships now reach real estate scale for a tiny fraction of mega-mower cost: the Mammotion LUBA 3 AWD 5000H (~1.25 acres, AWD to 80% grade), the Segway Navimow X350 (~1.5 acres mapped), and Yarbo for modular multi-task yards. Start where the consumer side does its best work:

• Find your robot mower — the configurator sizes and shortlists in six questions.
• Best robot mower for large yards and for 2 acres — the estate-scale shortlists.
• Robot lawn mowers, explained — the residential pillar and full catalog.

Step up toward a FireFly-class platform only when a single contiguous area runs into the tens of acres, the turf is agricultural or turf-grade, and you have an industrial capital budget and a dealer relationship.

How to buy: dealer quote and the lead-gen path

Because this is B2B, there is no add-to-cart and no published price. The path is: confirm you're truly in the mega-mower tier, decide whether the AMP-L100 (golf/sports) or the M-series (sod/field) matches your work, then request a direct/dealer quote scoped to your acreage, cut height, reel configuration, charging setup, and service coverage. Because FireFly is a pre-profit company that recently pulled its IPO, treat service continuity, parts, and software support as first-class questions in that conversation — not afterthoughts. And run the ownership math against alternatives on our commercial robot mower cost & ROI guide before you commit.

Wherever a referral relationship exists between MowScout and a dealer or manufacturer, it's disclosed and never affects how we describe a platform.

Frequently asked questions

Is the FireFly Automatix AMP-L100 right for a homeowner or small commercial lawn? Almost certainly not. It's a 100-inch, ~25-acre-per-charge industrial machine for sod farms, golf fairways, sports complexes, and large open grounds, sold B2B by dealer quote. A residential lawn — even a large one — wants the residential catalog and our configurator. The real reader for this page is a turf-farm operator, golf superintendent, or large-grounds manager.

How much does a FireFly Automatix AMP-L100 cost? FireFly doesn't publish a list price and we won't invent one. For scale, a CEORA runs ~$32,800 and an ECHO TM-2000 ~$15,500; a 100-inch, 35 kWh, five-gang autonomous reel platform sits well above that tier as a capital purchase. Treat any figure as a dealer estimate until you have a written quote — there is no checkout price here.

What autonomy technology does the AMP-L100 use? RTK-corrected GNSS (dual antenna) for positioning and virtual boundaries, LiDAR for obstacle detection (~40–50 ft), and cameras for classification and monitoring, with built-in Starlink for connectivity. The autonomy lineage began with a 2018 ASI (Autonomous Solutions) partnership using Mobius; FireFly has since built its own AMP stack (Path Linking, SmartStart, Exclusion Zones, Auto Sectioning).

Did FireFly Automatix go public? What happened to the FFLY IPO? FireFly filed for a ~$25M Nasdaq IPO under ticker FFLY (confidential April 2025, public October 2025) and then withdrew it on March 16, 2026 amid market headwinds. As of mid-2026 FFLY is not traded. The filing remains a useful window — ~$44–48M revenue, 770+ machines in service — alongside candid disclosures of continuous net losses and a stockholders' deficit.

How does FireFly compare to Husqvarna CEORA or ECHO Robotics? Different weight class. CEORA cuts 26.8" (~6 ac/24h), ECHO's TM-2050 cuts ~41"; the FireFly AMP-L100 cuts 100" and covers up to ~25 acres per charge. CEORA/ECHO fit a single course or field; FireFly fits a sod farm, a whole-course fairway fleet, or hundreds of contiguous acres. It plays above the mid-tier robots, not against them.

Has MowScout tested FireFly's mowers by hand? No. This overview is spec-verified and data-driven, drawn from FireFly materials, its SEC filing, ASI disclosures, and trade press — each traceable to the source list below. We haven't run an AMP-L100 or M220-AV, and every price is a dealer quote or estimate.

Bottom line

FireFly Automatix is the ceiling of autonomous mowing — a genuine mega-mower class born on sod farms and extended to golf fairways and large-acre turf. The AMP-L100 backs the "mega" label with verified specs: a 100-inch cut, up to ~25 acres per charge, an all-electric 35 kWh LFP drivetrain, and an RTK + LiDAR + camera autonomy stack with ASI roots, all proven across 75,000+ acres and 770+ machines in the field. The ~$25M FFLY IPO filing — now withdrawn — is both a scale signal and a real reminder to weigh vendor durability. For the handful of MowScout readers who actually run sod, fairways, sports complexes, or large open grounds, it's a serious, citeable platform worth a dealer quote. For everyone else, it's the fascinating top of a market you'll buy several tiers below — and the honest next step is the configurator, with the full commercial hub for the tiers in between.
