Many people want to get a SodaStream but have no idea which model is best for them. It can be difficult to choose, especially when the SodaStream company has no information highlighting the differences between the models. Here is a brief overview explaining which features are unique to the models.
There are currently eight SodaStream models available. They are The Revolution, The Source, The Fizz, The Crystal, The Pure, The Fountain Jet, The Dynamo and The Genesis. First, let's address the similarities of all eight types. All of the eight models can make soda or sparkling water in the convenience of your home. All come with "stay fizzy" bottle closures that keep the carbonation in longer. All are compatible with the standard 14.5 ounce carbonation cylinder which is capable of carbonating up to sixty liters of soda or sparkling water.
There are four models which are capable of using either the 14.5 ounce carbonation cylinder or the larger 33 ounce cylinder, which is capable of carbonating up to 130 liters of soda or sparkling water. Those four models are The Revolution, The Dynamo, The Fountain Jet and The Fizz.
All eight models use the CO2 tank as a power source to carbonate. The Crystal, The Pure, The Dynamo, The Fountain Jet and The Genesis require no additional power source to operate. The Fizz and The Source do require a battery to operate the display components. That battery is included. The Revolution is the only model which requires electricity to work. Keep this in mind, as it will need to be near an outlet when used.
The Crystal comes with a dishwasher safe glass carafe. The other seven models come with BPA-free plastic bottles that are not dishwasher safe. You can buy dishwasher safe bottles separately that are compatible with those seven models, but you can not use the glass carafe with any model other than the Crystal.
The Dynamo, The Fountain Jet, The Pure, The Fizz and The Genesis all require the user to twist the bottle into place. The Crystal, The Revolution and The Source all lock the bottle into place without twisting, making them a little easier to use.
There is only one fully automated SodaStream available at this time. That is The Revolution. You simply press a button to tell it how carbonated you would like your drink and it does the rest for you. It also measures the CO2 levels to let you know how much is left in your carbonation cylinder. The Fizz is not automated but it does monitor and display the amount of carbonation in your drink as well as the level of CO2 in your cylinder. The Source has three LED lights to let you know how much carbonation is in your drink, but does not monitor the CO2 left in your cylinder.
