Eureka, we've found it – the Nuova Simonelli MDX On Demand commercial grinder! Featuring two (electronic!) programmable dosing options and an easy-to-use stepless grind adjustment for endless fineness settings. Effortlessly adjust the coffee spout for just the right dispensing angle and watch the grinds fall into place as the integrated dispensing light brightens the way. With convenience like this, who says you can’t find good help these days?

The MDX On Demand was previously known as the Eureka Zenith grinder, as we reference in the below video. All of the features and the appearance of the grinder remain the same, the name was the only change made to the grinder.

Features and Functionality

  • Coffee Counter - Keep track of your day, or at least the number of shots dispensed with the MDX's coffee counter. Reset the counter at your convenience to start anew.
  • Stepless Grind Settings - Easily find just the right grind with the stepless adjustment knob.
  • Free Your Hands - Rest your portafilter in the adjustable holder, allowing you to multitask as coffee dispenses.
  • Dosing Options - Utilize the two programmable dosing options or the continuous mode.
  • LCD Display - Watch the animated coffee cup fill up as coffee is dispensed.
  • Stop Gate - Allows you to remove the hopper with beans still inside.
  • Worry Free Cleaning - With the MDX On Demand, there is no need to recalibrate the burrs after routine cleaning. Saving you time and potential maintenance fees.
  • Grind Adjustment - Effortlessly manage micro-adjustments with this stepless grinder.
  • Messy - There is no getting around it, every grinder is messy in one way or another. However, we found this grinder to be a bit staticky as some dispensing grounds easily stuck to the front of the grinder. Nothing a good wipe can't handle!
