Your regulars don’t care about the engineering behind the bar; they just want their third shot of the morning to taste exactly like the first. When the line hits the door, the internal two-fan cooling system becomes the most important part of your workflow by preventing the heat creep that ruins extraction consistency. This is a grinder for the operator who knows that a reliable dose is the difference between a smooth service and a frustrated lead barista. It is built for the reality of high-volume espresso, where there is no room for equipment that needs to be babysat.

Product Features

Quick, Stable Cleaning

The new lower burr carrier is designed for easy disassembly and cleaning while the upper burr remains stationary. That lets you clean without losing your grind setting — critical for fast, consistent service.

Low Retention Design

A completely redesigned grinding chamber and lower burr carrier deliver a 52% reduction in retention versus the previous model. Less retention means less waste and fresher shots in a high-volume environment.

Grind Flow Control (GFC)

The removable aluminum outlet insert accepts three interchangeable wire dampers (one versatile damper ships installed) to manage clumping, particle distribution, and counter mess. The GFC includes a digital display for straightforward adjustment to match origin, roast, or conditions.

Two-Fan Cooling System

A fan on the 800 W motor provides continuous cooling during doses, and a secondary low-voltage fan runs for 30 seconds after dosing to stabilise internal temperature. That temperature management helps protect delicate flavors during sustained grinding.

Programmable Dosing + Barista Pause

Three programmable dose settings with a barista pause feature let you interrupt and resume a dose for portafilter handling without reprogramming. The dosing controls are familiar to Robur users, making it fast to integrate behind a busy espresso machine.

71 mm Burrs & 800 W Motor

Equipped with 71 mm steel conical burrs and an 800 W motor running at 500 RPM, the Robur S averages about 3.5 g/s output. Those specs provide the throughput and grind consistency needed for commercial service.

The Coffeeionado Take

Who's It For:

  • Professional Espresso Bars — Cafés that need reliable, consistent dosing shift after shift. The 71mm conical steel burrs deliver the repeatability commercial service demands
  • Continuous-Service Operations — The 1600g hopper capacity means fewer refills during peak hours, keeping baristas focused on drinks rather than bean management
  • Italian-Made Purists — Manufactured in Italy with the build quality that implies. For those who value proven engineering pedigree

It's Right For You If:

  • You need a grinder built for the demands of professional espresso service — the 71mm conical steel burrs and stepless grind adjustment give you the precision and speed a busy bar demands.
  • The 1600g hopper keeps you grinding through peak hours without constant refilling — practical for continuous service environments.

Things to Consider:

  • At 28.0kg, this is a permanent counter fixture — not something you'll move for cleaning. Plan your bar layout accordingly.
  • No programmable dosing presets — you'll be manually timing or weighing each dose. Some baristas prefer this control; others find it adds a step to the workflow.

Our Take:

The Mazzer Robur S is a serious commercial grinder with 71mm conical steel burrs and the build quality to run all day. If your café needs reliability and consistency at volume, this delivers.

What We'd Tell You In Store

How to Choose a Commercial Espresso Machine

How to choose a commercial espresso machine based on real volume numbers, peak hour output, and drink mix — not vague categories.

How to Choose a Commercial Grinder

Your espresso machine gets all the attention. The grinder does all the work. Every variable that determines shot quality — particle size, extraction evenness, dose consistency — starts at the grinder.

How to Design Your Cafe: Build Your Bar for the Rush

Design your café bar for peak volume, not average traffic. Equipment layout, station design, staffing ratios, and tools that remove steps — what actually matters during the rush.

Setting Up Your Commercial Espresso Machine Right

Water pressure, electrical specs, drain slope, filter flushing — what actually goes into a commercial espresso machine setup, and what gets skipped.

Product FAQ

What type and size of burrs does the Mazzer Robur S use, and are they conical or flat?

The Mazzer Robur S uses large conical burrs (71 mm) designed specifically for high-volume espresso grinding. Conical burrs provide excellent particle consistency, low heat transfer, and are ideal for busy espresso service.

How long do the burrs typically last, and how often should I replace them?

Burr life depends on volume and bean hardness, but for most commercial environments you can expect roughly 1,500–2,000 kg of coffee before replacement is recommended. In very busy cafes this may mean replacement every 12–18 months; in lighter use settings, they can last several years. Monitor grind speed, consistency, and flavor—slower grinding and flatter-tasting shots are signs it’s time to change burrs.

Is the Mazzer Robur S a stepless grinder, and how precise is the grind adjustment?

Yes, the Mazzer Robur S uses stepless micrometric grind adjustment. This allows for extremely fine tuning of grind size with no fixed ‘clicks,’ making it ideal for dialing in espresso shots very precisely.

Is the Robur S suitable for my type of business or setup (café, restaurant, high-volume bar)?

The Mazzer Robur S is designed primarily for commercial and high-volume environments such as specialty cafés, coffee bars, and busy restaurants with significant espresso drink demand. Its powerful motor, large conical burrs, and fast throughput make it best suited to operations pulling many espresso shots per hour rather than very low-volume setups.

Can the Mazzer Robur S grind for both espresso and filter coffee?

The Robur S is optimized for espresso and very fine grind settings. While it can be adjusted coarser, it is not the most convenient choice if you frequently switch between espresso and filter settings. It’s best used as a dedicated espresso grinder rather than a multi-purpose grinder.

How fast is the Mazzer Robur S, and can it keep up with multiple drinks during rushes?

The Robur S is engineered for speed and consistency in busy service. With its powerful motor and 71 mm conical burrs, it can grind a typical double espresso dose in just a few seconds, allowing it to keep up with a high volume of drinks during peak periods in a busy café or restaurant.

Does the Mazzer Robur S have timed or manual dosing, and is it a grind-by-weight grinder?

The Mazzer Robur S offers electronic, programmable timed dosing so you can set precise dose times for single, double, or custom shots, as well as manual dosing if needed. It is not a true grind-by-weight grinder; dosing is controlled by time rather than an integrated scale.

Does the Robur S have a cooling fan or features to manage heat during heavy use?

Yes, the Mazzer Robur S is built for continuous commercial use and incorporates design features to manage heat, including efficient motor design and airflow. Selected configurations include active cooling (fan-assisted) to help keep the grinding chamber and motor temperature stable during intense rush periods, which protects coffee quality and grinder longevity.

Do you ship to PO boxes?

No, we don't ship to PO boxes. Due to the size and weight of our equipment, we require delivery to a physical address where our carriers can safely drop off your order.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 30 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is your responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be your responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If your location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain your responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
