The LUCCA M58 Sunto with Flow Control is the end-game dual-boiler, rotary-pump espresso machine, built by Quick Mill in Milan, Italy. Super compact for an E61 dual-boiler in its class, it combines E61 brewing precision with modern dual-boiler performance, wrapped in minimalist stainless steel or a sleek matte-black finish, both outfitted with walnut trim. With a built-in OLED PID controller, shot timer, programmable pre-infusion, flow control, a group head heating element that gets you up to brew temperature 40% faster than standard E61 machines, and the choice to plumb directly or run on its internal reservoir. The M58 Sunto with Flow Control is designed for the home barista who wants commercial capability without the complexity. This is the machine Clive's team reaches for when they want to dial in a new single origin or pull back-to-back drinks for a crowd.
Key Features
- Dual Boiler System: Separate 0.75L brew boiler and 1.5L steam boiler with independent PID control. Brew and steam simultaneously without temperature compromise.
- Flow Control: The LUCCA E61 Stainless Steel Flow Control system is pre-installed for your convenience and is the ultimate tool for tailoring your shots to your taste.
- Compact Profile: A mighty effort was made to make the M58 Sunto with Flow Control one of the most powerful and compact dual-boilers in its class. Smaller than the original M58 and many traditional E61 dual-boilers, without sacrificing an ounce of performance or counter space.
- E61 Group Head: The standard for espresso temperature precision since 1961.
- Instant Stability: A dedicated heating element in the group head brings the M58 Sunto with Flow Control to full brewing temperature in just 12 minutes, which is 40% faster than standard E61 machines.
- Flow Control Device: Pre-installed paddle on the E61 group head. Adjust flow rate and pressure during extraction to unlock new flavor profiles and rescue challenging beans.
- Rotary Pump: Whisper-quiet operation and stable, adjustable pressure. Unlike vibratory pumps, the rotary pump won't wake the household during your 6 a.m. shot.
- OLED PID with Shot Timer: Navy-blue PID display with 0.1°C accuracy. Integrated shot timer tracks extraction in real time.
- Switchable Water Supply: Plumb directly to your water line or run on the built-in 3L reservoir. A braided water line is required for plumbed operation and is sold separately here.
- Joystick Steam & Water Controls: Smooth, single-motion control for steam and hot water. More precise than traditional knobs, easier to clean.
- Walnut Bottomless Portafilter Included: Ships with a Clive-made walnut bottomless 58mm portafilter so you can watch channeling, dial in faster, and pull more beautiful shots.
- 1400W Heating Elements: From cold start to pulling a shot and steaming 12oz of milk, the M58 Sunto with Flow Control recovers to target temperature in under 60 seconds.

Frequently Asked Questions
Don't take our word for it.
This espresso machine earns praise for its beautiful design and "fantastic espresso." Customers highlight flow control features and reliable performance, with one noting "10+ years and still going strong." However, concerns include a drip tray that "fills up very fast," pump noise louder than expected, and one challenging service experience.
- 10+ years and still going strong - best espresso machine I've ever owned
- Beautiful and makes fantastic espresso. Flow control helps pull better shots.
- Beautiful piece of machinery. Consistent, quick, and dependable. Workflow is effortless.
An update, this has been the best espresso machine I've ever owned, ten years, 11 in October. I’ve had one switch go out; I was able to replace it myself at home.
Sweet
I recently purchased a Lucca M58 with Flow Control. Overall, it has been a miserable experience. After about 3 months it started blowing a fuse in my outlet. I reached out to Customer Support whom made it sound like it was my fault. They sent me a bunch of videos on how to take the machine apart and asked that I send pictures. After taking the machine apart I realized I am not an espresso machine technician so I put it back together as best as I could based on the videos. I then reached out to see what should be done and they said I should send the machine back in its original packaging but first I need to drain the boilers. They sent me video on how to drain the boilers but unfortunately the boiler screws are too tight and I am not able to drain the boilers. Customer Service also mentioned to take the machine into UPS or Fed Ex and have them set me up with a heavy package rate and to make sure I insure everything prior to shipment. I am a little shocked they did not offer to send me prelabeled package with a box considering all the money that I spent. As of now the machine has been sitting idle in my kitchen for about 3 months with no end in sight. If the goal of Clive is to have espresso machines in every home, they need to do a much better job servicing and fixing their machines. I would suggest regional repair people etc. As of this moment I cannot recommend this machine or Clive to anyone based on my experience. Do not fall for the trap.
The overall machine is great but the drip tray fills up very fast with water.
I've had it for 6 months, and it works great and does everything I need, except for an on/off timer. I easily addressed that with a smart plug. It's a beautiful machine. Be warned: it is large and heavy, so make sure your kitchen/coffee bar area can accommodate it. Whatever machine you go with, rest assured that Clive's support is amazing!
The Lucca M58 w/Flow Control is a beautiful countertop queen. I have been exploring both with pre infusion, flow and different brew temps to tweak sweetness and depth from the different beans I’ve been using.
There is quite a learning curve and an emphasis on perfecting a repeatable workflow so that adjustments are revising one variable.
In any case, my milk steaming is on point as well as getting my dosing correct. The toggle levers for steam and water are dope. The walnut knobs are high Q finish.
Only gripe is noise. Clive touted a ‘near silent’ rotary pump - but it isn’t. It makes almost as much racket as my old Ascaso Uno thermoblock.
Got this Lucca for my wife’s small bakery/cafe and it’s amazing! Draws a lot of attention cause it’s a beautiful piece of machinery. Even better it operates to perfection. Consistent, quick, and dependable so far. Paired with an eureka grinder the work flow is effortless.
Heats up quick, great expression machine!
Pros:
- I love the look and feel of this machine. It has been absolutely awesome to use, I get compliments from everyone that comes visit and it is just pleasant to use.
- I do not have enough experience with it to say that is has blown my mind with the espresso from it (I have had it for almost a month), but overall so far has been great.
- Love the design choice of having the ability to turn on and off the steam boiler right there in the front of the machine, it was probably one of the key selling points for me since I normally do milk drinks in the morning and a shot or two in the afternoon and I don't want to have to pull the tray out or get into the PID to shut the steam boiler off every day as some of the other machines make you do.
Cons:
- The drip tray is a bit short. I got an Acaia Lunar scale and I need to put it on the frame of the tray because the mesh seems flimsy (even then, the scale is not fully stable). I would have chosen a slightly larger drip tray design without the mesh and have something sturdier instead (I have to say that I like the look of the mesh, but is just not functional). My scale goes a bit nuts when I put it on the mesh and also gets wet from the exhaust when pulling a shot. Clive, I hope you take this feedback and you make a better drip tray for this to improve this experience.
- I experienced something odd with the steam boiler. My machine run out of water as I was pulling hot water and the steam boiler started to try to pull water from the reservoir, but there was none, so as the machine was trying to pull water I started to see that the pressure in the steam boiler started to raise and raise up to the point of going beyond 2 bars and into the red zone, and I got so worried/scared that I just shut off the machine. After that I put water on the reservoir and turned it on and everything was fine, but makes me wonder what the heck happened there because the machine is supposed to have safety measures to identify when there is no more water. Clive, any ideas???
The best Espresso machine ever
What a beautiful machine that makes great espresso! It took me a while to fine tune everything for that perfect cup, but now that I have my Lucca is used every single day from morning to night.
Love it...only thing it's missing honestly is an auto on timer function
Beautiful and makes fantastic espresso. The flow control is especially helpful in adjusting extraction more easily to pull better shots.
