Comparison
The GS3 AV and GS3 MP are the same machine underneath. One automates the shot with programmable volumetric dosing; the other hands you a paddle. Here's how to choose between them.
The GS3 AV and GS3 MP are the same machine underneath — same dual boiler, saturated group, 58mm portafilter, and hand-built in the same factory in Scarperia, Italy. At $11,499 and $11,999, they’re only $500 apart on a machine north of eleven grand, so this isn’t a budget decision. The real question is who drives the shot: the AV automates it with flowmeter-measured dosing and four programmable buttons; the MP hands you a paddle over a conical valve and lets you shape the flow yourself. Both are excellent — this guide is about matching the machine to how you actually want to make coffee, not picking a “better” one within the La Marzocco range.
Buy the GS3 AV if:
– More than one person uses the machine and you want the same shot every time, automatically
– You’d rather program a dose once and press a button than manage flow by hand
– You want an automated cleaning cycle rather than a manual routine
Buy the GS3 MP if:
– You want to shape the shot yourself, shot by shot, with a paddle in your hand
– You already grind well and want manual control over flow rather than a repeatable factory setting
– You enjoy the process as much as the coffee — reading the periscope manometer and adjusting as you go
Nobody should choose between them on price — $500 apart at this level is close to noise. The decision comes down to whether you want the machine to make the same call every time, or whether you want to make it yourself.
Everything on the GS3 AV and GS3 MP is identical except how each one lets you control the shot.

Before getting into what’s different, it’s worth being upfront about what isn’t. Both GS3s share:
One more thing worth saying plainly: the GS3 is a single-group machine. You’ll see copy elsewhere — including on La Marzocco’s own site — describing the GS3 pre-infusing “one group while the other is extracting.” That’s carried-over language from multi-group commercial machines and doesn’t apply here; the GS3 you can buy for home is built for one group, one operator.
None of that changes between AV and MP. Everything you’re actually paying the $500 difference for happens between the boiler and the cup.
The AV in GS3 AV stands for Auto Volumetric: a flowmeter measures the water going through the group, so instead of eyeballing your shot or timing it by feel, you press one of four programmable dose buttons and the machine stops exactly where you told it to, every time.
That matters more than it sounds on paper. Once you’ve dialled in your grind and dose, four buttons means four repeatable outcomes — a short black, a long black, someone’s usual flat white shot — without anyone needing to know the machine to get it right. Pre-infusion is programmable too, so the gentle ramp before full pressure is set once and then just happens.
The AV also runs an automated cleaning cycle, which is the other half of what “automatic” buys you: instead of a manual routine, the machine handles its own cleaning on schedule — one less thing for a busy household to remember or skip.
Put together, the AV suits the household or café-at-home setup where consistency matters more than involvement: multiple people using the same machine, guests who want their coffee to taste the same as last time, or an owner who wants excellent espresso without treating it as a hobby that needs tending. It’s a GS3 doing the automation half of its job properly, with the same boilers and group underneath.
Where the AV automates, the MP hands you the controls. Instead of a flowmeter and buttons, the GS3 MP gives you a paddle sitting over a conical valve, and you open and close it yourself across the shot — progressive control over water flow, and by extension the pressure the coffee actually sees.
That’s a genuinely different way of making a shot. Pull the paddle open gently and you get a soft ramp into full flow; open it further and hold, and you get something closer to constant pressure; ease off toward the end and you can taper a shot the way an AV’s fixed pre-infusion curve never will. A periscope manometer sits above the group so you can watch what’s happening — pressure in real time, not a number you’re trusting blind.
None of that is automatic, and that’s the point. The MP rewards attention: dial in your grind, learn how your paddle hand affects a given bean, and you can chase an extraction the AV can’t replicate on demand. It also punishes inattention — get distracted partway through and you’ll taste it. There’s no automated cleaning cycle either; the MP is cleaned manually, in keeping with a machine built around doing things by hand.
That honesty matters, because “manual control” gets romanticised in coffee forums more than it gets explained. The MP isn’t more capable than the AV in some general sense — it’s a different tool for a buyer who wants to shape each shot rather than program it once and walk away. If you already adjust grind and dose for a particular bean, the MP gives you one more lever to work with, live, while the shot is running.
It’s worth being precise about what the MP’s paddle actually gives you, because “pressure profiling” gets used loosely in this part of the market. The MP is flow control: you’re manually controlling how much water moves through the group at any moment, and pressure follows from that as a downstream effect. It is not a programmable pressure profile that you set once and the machine then repeats shot after shot.
That distinction matters if a programmable profile — dial in a curve, save it, walk away — is specifically what you’re after. The MP won’t do that; it needs your hand on the paddle for the whole shot, every time. What it gives you instead is live, progressive control over flow in the moment — a different, and for many people more engaging, skill than programming a profile once. For the full explanation of how flow and pressure relate during a shot, see our pressure profiling guide.
At $11,499 for the AV and $11,999 for the MP, the gap is $500 — under 5% of the purchase price, and not a number worth optimising for. If the AV’s automation or the MP’s manual control genuinely fits how you want to make coffee, $500 either way isn’t the deciding factor.
What that Australian price includes: GST, a genuine La Marzocco Australian warranty, and support through La Marzocco’s Australian service network for anything the machine needs down the track.
We won’t discount either machine below La Marzocco’s set Australian pricing, and you won’t find a legitimate new GS3 advertised that way. Which raises the obvious question: what about the listings you will find well below this price?
Search for a GS3 and you’ll find some priced several thousand dollars under what’s listed here. Those aren’t new machines at list price — they’re used or refurbished GS3s, often ex-café units, sometimes custom-refinished in colours La Marzocco never shipped. Sellers typically bench-test and service them before resale, and they commonly carry a short parts warranty — three months is a common figure — rather than the manufacturer’s Australian warranty that comes with a new machine bought through an authorised stockist.
That’s not automatically a bad buy. A well-refurbished commercial-grade machine like the GS3 can have plenty of life left in it, and the saving is real. What you’re weighing up is genuine: a few thousand dollars against full warranty cover and a machine nobody has run hard for years before you got it.
It’s also worth connecting this to the maintenance worries you’ll see raised about the GS3 online. A used, commercial-derived machine with unknown history is exactly where “high maintenance” stories tend to come from — not because the GS3 platform is fragile, but because you don’t know what it’s already been through. A new machine with full warranty and no prior owner removes that variable entirely.
The GS3 AV is the right choice if repeatability matters more to you than ritual. If more than one person makes coffee on the machine — a partner, kids old enough to want a coffee, houseguests — programmed doses mean everyone gets the same shot without needing to learn the machine first. It also suits anyone who wants excellent espresso as a daily outcome rather than a project: the automated cleaning cycle and volumetric dosing take two variables off your plate entirely.
Pairing it with a grinder that’s just as repeatable matters too — our grinder guide covers what to look for at this level. The AV won’t stop you experimenting with dose and grind; it just means once you’ve found what works, the machine holds it there.
The GS3 MP is the right choice if you want to be the one shaping the shot, not the machine. If you already grind well, adjust dose and time for a particular bean, and enjoy the process as much as the result, the paddle gives you a lever the AV doesn’t: live control over flow while the shot is running.
It also suits a buyer specifically chasing what flow control can do with tricky beans — a light-roasted single origin that wants a soft start, for instance. Grind quality matters just as much here as on the AV, so it’s worth working through our grinder guide above if you’re building out the rest of the setup. The MP rewards a buyer who wants to keep learning the machine, not just own it.
Underneath they’re the same machine — the same dual-boiler layout, the same saturated group head, the same 58mm commercial portafilter, built the same way in the same factory. The difference is control. AV stands for Auto Volumetric: a flowmeter measures the water, four programmable buttons give you repeatable doses, and pre-infusion is programmable. MP stands for Manual Paddle: you open and close a paddle over a conical valve yourself, shaping the flow through the shot, with a periscope manometer to show you what’s happening. One automates the shot, the other hands it to you.
Not in the strict sense. The paddle gives you manual control over water flow, and pressure follows from that — it’s flow control rather than a programmable pressure profile. That’s a real distinction: you’re steering the shot by hand in the moment, not dialling in a curve the machine then repeats. If a programmable profile is what you’re after, the GS3 MP isn’t the machine for it.
If more than one person uses the machine, or you want the same shot every morning without thinking about it, the AV is the easier machine to live with — programmed doses and automated cleaning take the variables out. If you enjoy the process and want to shape each shot, the MP is the one you’ll keep reaching for. At $500 apart on a machine of this price, buy the one that matches how you actually want to make coffee, not the cheaper one.
We don’t comment on unreleased products, and neither does La Marzocco until something is announced. What we can say is that the GS3 is a long-running, commercial-derived platform with well-established parts and service behind it, which is what actually protects a purchase at this level. Machines like this are bought to be serviced and kept for decades rather than traded up, and the ones we see in the workshop bear that out.
Because those are almost always used or refurbished machines rather than new ones. Refurbished GS3s — often ex-cafe, sometimes refinished in custom colours — get bench-tested and resold, and they typically carry a short parts warranty of around three months rather than the manufacturer’s Australian warranty that comes with a new machine. That can be a perfectly sensible buy if you know what you’re taking on. What you’re weighing up is a few thousand dollars against full warranty cover and a machine with no history behind it — so it’s worth knowing which one you’re looking at before you compare prices.
Both versions come with genuine Australian warranty, and warranty and service work is handled through La Marzocco’s Australian service network. The machines are brought in to order, so ask us about current lead times for machines and for parts before you buy. As with the rest of the range, the single best thing you can do to protect the boilers is run filtered or softened water — on a machine at this level, water quality does more for longevity than anything else you control.
