Anyone who never makes two cups at once is well served by the simpler EQ.6 Plus s100.

Who for: Households that often make two milky coffees at once.

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.

Accessories that fit this machine

Picked on what this machine does and does not do itself

Maintenance

Essential

Descaler

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.

Maintenance

Recommended

BRITA Intenza water filter

The filter Siemens and Bosch share. It stretches the descaling interval and takes the off-notes out of hard tap water.

Beans 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.
