You can compare the technical characteristics of the models from the review in the table. And if you want to choose a coffee maker or coffee machine yourself, take a look at the specialized section of the catalog.
The water tank holds 2.2 liters and the bean hopper holds 250 g, which is above average. Three levels of grinding, temperature, strength and pre-wetting of the coffee tablet.
Limited grind settings. No automatic frothing per recipe.

The device has a compact form factor with a body width of only 24 cm. The water tank of the coffee maker has a volume of 2.2 l (more than the average "in the ward"), and the capacity of the grain hopper is about 250 g. In addition, there is the ability to work with ground coffee. In terms of settings, the 756th model provides for "all by 3" adjustments - so many degrees of grinding are provided for coffee beans, the same number of gradations have settings for temperature, strength and the degree of pre-wetting of the coffee tablet in the "brewer" (Aroma Balance System).

The drink selection menu of the Nivona CafeRomatica 756 is implemented as a "carousel" on a color screen. The selection is made by rotating the right wheel, and the preparation procedure is started by pressing the button in the center of the wheel. To the left of the display is a wheel for setting the strength of the drink and the volume of the portion. From a smartphone with the pre-installed Nivona application, you can remotely start the preparation of drinks with personal settings.

Adepts of drinking a cup of hot latte or cappuccino will appreciate the separate adjustment of the volume of milk dispensed and the height of the foam "cap" (accurate to a milliliter). The downside is the lack of a program for "correct" cappuccino. Unfortunately, the coffee machine does not know the filling sequence "coffee, then milk". But this is not a problem, since the "canonical cappuccino" can be made in two steps - first pour espresso into the cup, then add milk foam.

21 programs, including rare recipes. 4 user profiles with precise adjustment of drink parameters.
Advanced settings are only available via smartphone.

The model belongs to the flagship guard of coffee "machines". The upper half of the "facade" of the coffee machine is occupied by a touch control panel with buttons, sliders and a large color screen. The most popular drinks are launched literally in one click (espresso, coffee crema, cappuccino, latte macchiato), the remaining 17 names - start from the menu in a couple of clicks. From a drink of an unusual recipe, Melitta Caffeo Barista TS Smart F86 / 0-100 prepares Scandinavian Americano Long Black and a killer in strength "dead eye" Dead Eye (three portions of ristretto are successively added to the coffee crema).

The coffee machine has 4 pre-installed user profiles. They allow you to set the amount of coffee, milk, hot water and foam to the nearest milliliter, specify the slot of the two-chamber bean container, and set the brewing temperature and strength parameters. Access to the detailed settings is available from the Melitta Connect mobile app when connecting a smartphone or tablet to the coffee machine via Bluetooth. By the way, in automatic coffee brewing modes, the model automatically uses beans from the left slot for espresso-based drinks, and from the right slot for coffee crema-based drinks.

The coffee "machine" is equipped with a height-adjustable dispenser with twin outlets for coffee and milk. In one go, Melitta Caffeo Barista TS Smart F86/0-100 pours two servings of coffee or coffee-milk drinks. The model will please you with a huge variety of recipes for automatic preparation of an invigorating drink, the intenseAroma function for increasing the overall saturation of coffee by increasing the duration of pre-wetting of the coffee tablet, and advanced functionality in general. With such a barista in the kitchen, you will definitely not get bored!

The removable brewing unit and several self-cleaning modes make it easier to maintain the device. The working tanks have a really good capacity, including a 500-gram grain hopper, a 2.2-liter water tank, and a container for 14 servings of grounds, which allows you to remove them less often.

The Siemens coffee machine features the proprietary iAromaSystem technology, which is responsible for high-quality extraction – revealing the taste and aroma of the drink. The beautiful name hides reliable equipment, including ceramic millstones with 6 grinding degree settings, temperature control sensors for a 1500 W heater, a high-quality pump with pressure up to 19 bar and a removable brewing unit that is easy to wash under running water.

Siemens EQ.700 classic TP703R09 is not the most compact device (31x38x47 cm), but it has acquired a solid hopper for beans (350 grams) and a large water tank for 2.4 liters, so frequent “refills” are not required.

The coffee machine can be recommended to fans of both black coffee and drinks with milk. It has an automatic cappuccino maker that can serve foam in two cups, which means you can make 2 cappuccinos or lattes at the same time. The default recipe settings can be changed - adjusting the volume, water temperature or strength, up to using the aromaDouble Shot option with a double portion of espresso. Plus, you can save 5 of your own recipes in memory.

This is a solid option for demanding coffee connoisseurs.
