EssentialDescaler
Limescale is what most machines die of, and vinegar attacks the seals. A liquid descaler declared suitable for espresso machines does the same job as the maker’s own branded fluid, usually for less.

Price alert
When the EQ.900 plus iAroma drops
Espresso machines drop hardest around Black Friday and in the weeks before Christmas. Leave your email address and pick below what you want to hear about.
The EQ.900 plus has two bean hoppers each with its own grinder, a 6.8 inch touchscreen and a baristaMode in which you set the brew parameters yourself. Cleaning and descaling are automatic, with cartridges Siemens requires for it.
That last one is a running cost to budget for. Anyone not drinking two beans side by side gets most of this for less with an EQ.700.
Who for: Anyone who drinks two beans side by side and wants the upkeep automated.

This is what we know for certain. Dimensions and capacities the manufacturer or the shop does not state are left out rather than estimated. A measurement or a tank volume that is not there is one we do not have.
What does it cost a year to maintain?
A worked example, not a specification: 2 cups a day (730 a year), the intervals from the maker's manual, with the water filter the maker recommends, and the lowest price in our catalog today.
The maker states no maintenance intervals for this machine that we have been able to read.
How often you descale depends on your water hardness. Where the maker gives no interval for it, we leave it out rather than estimate it.
Beans, counted separately
6.57 kilos a year at 9 grams a cup: €117.80 with the cheapest kilo in our catalog, €445.45 with the dearest.

Go to CoolblueBeans for this machine
Every bean fits every machine. What differs is the order: on a bean-to-cup the 100% arabica beans come first, because dark-roasted blends carrying robusta give off more oil and that clogs a built-in grinder sooner.

All arabica, and so softer and more acidic than the blends carrying robusta. Anyone who finds espresso too harsh often starts here.
