The special feature of this blender is the vacuum pump which sucks air out of the glass jug before mixing, pureeing or crushing. That means crushed fruit and vegetables don't react with the air and retain more vitamins and freshness. At the same time, no air mixes in with the smoothie, making it even creamier and more delicious. The hose attachment pumps the air from the glass jug or storage cup out through a small opening in the lid. The pump itself is located in the base of the appliance and is turned on and off via the touch control panel. Once the air is removed from the glass jug, there are seven mix programmes and six power levels to choose from in order to make the perfect smoothie, creamy soup or freshest raw vegetables. All the functions will of course perform without the vacuum, too. The vacuum blender does not stop at smoothies. Cocktail lovers can use the practical blender for making crushed ice. The strong blades of the built-in knife crush blocks of ice into cocktail-sized pieces, so that drinks can be served at the right temperature. In addition, this blender is designed for all other mixing tasks. This device provides the basis for tasty soups, wholesome porridge or sweet pancake batter. The pulse switch also allows blending intervals to be individually configured. The blender is a practical kitchen aid which keeps smoothies, soups and raw vegetables fresh for longer thanks to its vacuum function.
