'Milk Tank' indicates whether the coffee maker has an attached milk tank or not.

Milk tanks are helpful for automatically heating and foaming milk to add to Italian espresso drinks such as lattes and cappuccinos. Otherwise you'll have to heat the milk and add it yourself.

The amount of coffee beans that the coffee maker can hold.

'Water Tank Capacity' is a measurement of how much water the coffee maker can hold at once.

A bigger water capacity means that the coffee maker will need refilling less frequently.

'Built-In Display' denotes whether the coffee maker has a screen displaying the coffee choices, current coffee brewing, any errors, etc.

A display allows you to quickly see the status of the coffee machine, choose drinks, etc.

The number of spouts used by the machine for pouring coffee.

Normally you only make one cup of coffee at a time - however machines with multiple spouts allow you to funnel the coffee into several cups at once.
