DeLonghi Eletta Explore vs Miele CM 5310: Which Should You Buy? (2026)

Q: Is the Eletta Explore better than the CM 5310?

It depends on your priorities. The DeLonghi Eletta Explore excels for users who want Cold Foam technology and To-Go cup clearance, while the Miele CM 5310 is the better choice if you prioritize compact German engineering and silence.

Q: How do the grinders compare?

The Eletta Explore uses a Steel Conical, whereas the CM 5310 features a Steel Conical. While both are high-quality internal systems, they are sealed components. To prevent clogging and avoid expensive repairs, we strongly recommend using non-oily, medium-roast beans in both machines.

Buy the Eletta Explore if you:

Want to brew Cold Foam lattes and To-Go drinks at home.
Need a machine with 40+ hot and cold recipe options.
Prioritize the superior micro-foam of the LatteCrema system.

Buy the CM 5310 if you:

Want compact German engineering and silence.
Need a powerful machine that fits in a tight space.
Appreciate the AromaticSystem for intense coffee flavor.
