Mazzer Robur S Electronic Coffee Grinder - On Demand - 71mm Burrs
Thermally Controlled Performance with Precision Grind Retention
Engineered for high-volume environments, the Mazzer Robur S Electronic utilizes powerful 71mm conical burrs to achieve an average grinding speed of 5g per second. To protect coffee aromatics during peak service, it features a double-fan cooling system and a low-RPM motor that operates at 420 rpm. Precision is maintained through stepless micrometrical adjustments and a Memory Track system , which allows baristas to index and retain specific grind settings even after cleaning the chamber.
Powerful Low-RPM Engineering for Consistent, Aromatic Results
Key advantages for the barista include the Grind Flow Control (GFC) system , which uses interchangeable wire dampers to eliminate clumping and static for a cleaner workspace. The ergonomic control panel supports 19 languages and enables triple-dose programming accurate to a hundredth of a second. Furthermore, IoT connectivity provides remote access to grinding statistics and maintenance alerts via the cloud , while the adjustable portafilter holder ensures hands-free operation and a perfectly centred flow.

Mazzer Robur Electronic vs Automatic: Which Heavyweight is Right for Your Café?
If you have spent any time behind a high-volume espresso bar in London or Manchester, you’ll know the name Mazzer. Specifically, the Robur—a beast of a grinder equipped with 71mm conical burrs designed to chew through kilos of coffee without breaking a sweat.

But when you’re looking to upgrade your kit, you’ll spot two distinct versions: the Electronic (On-Demand) and the Automatic (Doser). While they look similar from a distance, the impact on your workflow and coffee quality is significant.
The Mazzer Robur Automatic: The Traditional Workhorse
The "Automatic" model is the classic doser version. It grinds coffee into a front-mounted chamber, which the barista then dispenses by pulling a manual lever.
-
How it works: Sensors in the chamber detect when the ground coffee level is low. The "Automatic" function kicks in, grinding more beans to keep the chamber full, then stops once it's topped up (usually every 12 doses).
-
The Pros: It is lightning fast during a frantic morning rush. Since the coffee is already ground, a barista can flick the lever and have a portafilter filled in under a second.
-
The Cons: Retention and freshness. If the grounds sit in the doser during a quiet spell, they lose those delicate aromatics. It also leads to more "sweepings" and wasted coffee at the end of the shift.
The Mazzer Robur Electronic: The Modern Precision Tool
The "Electronic" (specifically the latest Robur S model) is an "on-demand" grinder. There is no chamber; the coffee is ground directly into your portafilter.
-
How it works: You program specific timings (e.g., 3.2 seconds for a double shot) via a digital display. When you trigger the grinder with your portafilter, it grinds exactly what you need.
-
The Pros: Unbeatable freshness. Every shot is ground to order, and with the new Grind Flow Control (GFC) system, static and clumping are virtually eliminated. The digital dose counter is also a dream for managers tracking yield.
-
The Cons: It takes a few seconds longer per drink compared to a pre-filled doser—a small price to pay for superior flavour.
| Robur Automatic | Robur Electronic (S) | |
|---|---|---|
| Delivery | Pull-lever (Doser) | Digital (On-Demand) |
| Dosing Control | Manual/Volumetric | Digital Timer (to 0.01s) |
| Waste Level | Higher (Chamber leftovers) | Minimal (Grind-on-demand) |
| Best For | High-turnover "Italian" bars | Quality-focused specialty cafes |
| UK Voltage | 230V Standard | 230V Standard |
Product FAQ: Your Questions Answered
Is the Mazzer Robur Electronic suitable for single-dosing? While the Robur Electronic has low retention (the Robur S reduces it by a further 52%), it is designed as a high-volume hopper grinder. For dedicated single-dosing in a low-volume environment, you might consider the Mazzer ZM.
How often do I need to change the 71mm conical burrs? For most busy UK cafes, we recommend changing the burrs every 800kg to 1000kg of coffee to maintain grind uniformity and prevent heat buildup.
Can I adjust the dose on the Automatic version? Yes. You can adjust the dose by turning the nut inside the doser chamber to increase or decrease the volume of the "pie segments." However, it is less precise than the Electronic version's 0.01s timer.
Does it come with a UK plug? Yes, all Mazzer units supplied by authorised UK distributors come with a standard 13-amp UK 3-pin plug and are rated for 230V.
