If you want to drink delicious vegetable smoothies, you don’t have to spend a fortune on a high-performance mixer – even if some manufacturers suggest it. We tested 22 smoothie makers in all price ranges. For us, the best is the Bosch Vitaboost: It can easily get everything small and offers an excellent price-performance ratio. It not only masters smoothies but also shakes, sorbets, sauces, nut butter and nut milk and can even prepare soups.
If you just want to drink a smoothie instead of a meal and not only want to eat bananas and strawberries, but also want to prepare a smoothie with ginger, kale or other fibrous foods, you cannot avoid a high-performance mixer.
Because high-performance mixers or smoothie makers chop the ingredients up at extremely high speeds. In this way, you can even get the woody plant fibers of stubborn vegetables creamy and fine.
While in the past you had to spend a small fortune on a good high-performance mixer, today inexpensive devices also deliver very good smoothie results – but not all, as our test shows. Here is our recommendation in the brief overview.
Bosch MMBH6P6B VitaBoost Blender

The Bosch Vitaboost does exactly what you expect from a smoothie mixer: It really gets all the ingredients small, no matter how hard they may be. Six automatic programs, high-quality workmanship and the great design make the device a highlight in the kitchen. The handling is also uncomplicated and it is fun to work with the device. The included plunger lies very comfortably in the hand and up to 30,000 revolutions per minute speak for themselves. In addition, the price-performance ratio is unbeatable.
Why do I need a Smoothie Blender?
Green smoothies are becoming more and more popular, they often replace breakfast or are a quick vitamin kick for in between. They are quick to prepare, because you simply put all the ingredients together in the mixer, press the start button and in no time you have a healthy, filling drink made from fruit or vegetables with lots of vitamins, minerals and valuable plant fibers.
Smoothies are prepared in high-performance mixers that use a lot of power and over 30,000 revolutions per minute to crush everything that comes between the blades.
Why doesn’t a normal mixer work? It’s simple: on the one hand, normal blenders are not designed for longer operation over several minutes, on the other hand, their performance is not sufficient to process vegetables in such a way that you get a creamy smoothie result.
If you want to make smoothies primarily from fruit, you don’t need a high-performance mixer – the stand mixer or the food processor can do the same.
Even if you want to try green smoothies first, you can do that with the conventional blender. The result is not as smooth as it could be, but it doesn’t make any difference in terms of taste. But then it’s best to try softer vegetables, because the fibrous residue is not exactly pleasant in the mouth.
If you often want to prepare green smoothies with vegetables, a high-performance mixer makes sense in the long run. Because only at very high speeds are plant fibers from harder vegetables such as celery, kale or spinach finely pureed. And without woody fibers in the mouth, a smoothie tastes much better.
More nutrients by breaking the cells?
The manufacturers also claim that when mixing with a high-performance mixer, nutrients are released by breaking the cell walls of plant fibers that the body cannot otherwise access.
It sounds so good that not only sellers but also self-proclaimed health apostles and journalists like to parrot it in trendy lifestyle articles. Above all, this statement is one thing: good marketing. Because there is no scientific evidence that this is so.
The digestive system is a real specialist in removing nutrients from food. It can break down fiber cell walls with the help of intestinal bacteria, for example. You don’t need a high-performance mixer for this.
But that doesn’t mean you have to do without green smoothies. If the bottom line is that you consume more fruits and vegetables with smoothies, you are definitely doing something good for your health!
And if you have digestive problems, a smoothie mixer can help, because finely pureed vegetables can be easier to digest.
And of course you can conjure up a few other delicious things with high-performance mixers: For example, fruit spreads made from nuts and fruit, ice cream made from frozen fruit or almond milk. To do this, blanched almonds are mixed with water. Here it takes a lot of turns so that the almonds and milk combine to form a homogeneous liquid.
And because the ingredients in the high-speed mixer heat up quickly due to the high speeds, you can even use them to prepare sauces and creamy soups quickly and easily – without a stove.
How did we test the Smoothie Blenders?
For the test, we prepared various green smoothies with all six devices. Not only soft, but also fibrous types of fruit and vegetables were used: mango, rhubarb, kiwi, pears, apples, bananas, as well as salads, fresh herbs and avocados.
One thing should be said in advance: the results were almost identical for all devices, there were only minor differences in the duration of the preparation, which, with one exception, are negligible.
All smoothie mixers prepared velvety smoothies, they were evenly pureed and did not have any pieces – just like a good smoothie should be. Nevertheless, there are of course differences between the mixers.
The containers of all smoothie mixers are made of BPA-free plastic, but differ in shape and size.
The shape of the blender jar should influence the vortex during mixing so that the ingredients are optimally fed to the blades – at least that’s the theory. In the test, however, we could not find any difference in the results with regard to the shape of the individual containers.
The containers can be easily attached to all mixers, while the gear wheel below the mixing container connects to the transmission of the motor block. This works on the same principle with all smoothie mixers. All devices have a safety switch on top of the engine block. The mixers only run when the blender jug is in place and stop automatically when the jug is removed from the engine block.
Disadvantage of all mixing containers: They are usually not suitable for the dishwasher. But if you rinse them under running water immediately after use, cleaning is done so quickly. Or you simply fill the used container with a little water, place it on the mixer and let it run for a few seconds – and it is clean.
All tested devices are similar with the blades. They are permanently installed in the container and cannot be removed for cleaning. There are four or six blades each.
The devices are also very similar in terms of processing quality, only with the Performance Pro from Russell Hobbs plastic was used for the gears and transmission. All other devices are made of high quality metal at the crucial points. The housings are mostly made of plastic, Russell Hobbs and WMF have also processed matt-brushed metal or Cromargan.
The smoothie mixers we tested hardly differ in performance either. All of them have an output between 1000 and 1600 watts, only the JTC OmniBlend V falls below the 1000 watt mark with an output of 950 watts.
They are also all big and heavy, they almost always weigh over four kilograms. But that has to be the case with so much power, the high weight guarantees a firm stand on the work surface when the mixer is in action.
We also measured the volume of the devices when they were idle. All devices were around 90dB. It’s very loud. When using ingredients, the volume is noticeably reduced, but no smoothie mixer is whisper-quiet.
In our last two test series, we had a demanding smoothie prepared for mix ratios. An apple, half a pear (each with a core), a banana, 3 stalks of celery or rhubarb, a carrot, some Chinese cabbage, a piece of ginger and a little mint were filled up to a third with water and then mixed for a minute. We also used the plungers included in the delivery.
Test Winner: Bosch MMBH6P6B VitaBoost Blender
The Vitaboost convinced us from the first second. Its modern, high-quality appearance caught the eye as soon as it was unpacked.

The Bosch Vitaboost has six automatic programs: Shake, Smoothie, Ice Cream, Soup, Sauce and Cleaning. You can use it to prepare a lot. There is a pulse function and with the help of a control wheel you can regulate the speed continuously.
With 1,600 watts and up to 30,000 revolutions per minute, the Vitaboost is a real powerhouse. Even whole apples are no problem for it. However, this performance is also noticeable acoustically. Like all high-performance mixers, the Bosch makes a lot of noise when in use: we measured around 90 decibels, which is quite remarkable. But that makes the Vitaboost no louder than comparable high-performance mixers.
The 2-liter container is only made of plastic, but makes a high-quality impression. Even the six times more expensive Vitamix offers only plastic for the container. There is a reason for this: for glass containers to be as stable as plastic vessels, the glass must be quite thick – and that makes them very difficult. Therefore, glass containers are not only cumbersome to handle but also, above all, to be cleaned.
The Bosch Vitaboost does not have this problem. It is easy to clean by hand. Overall, the Vitaboost impresses us with its clear, well-arranged design.
With its 5.2 kilograms and a height of 45.8 centimeters, the mixer is a real statement in the kitchen. The weight ensures good stability – after all, enormous forces are involved here. Thanks to its rubber feet, the device is absolutely stable.
The six stainless steel blades are partially serrated, which gives them a great grip. Replacement knives can even be reordered if required.
The plunger is stable and fits comfortably in the hand, the locking mechanism for the plunger inlet seals very well. A recipe book with over 30 recipes for smoothies, shakes and tips for healthy eating is included.
Our green smoothie had a creamy consistency and you could taste the ingredients wonderfully. Even the stubborn fibers of celery, carrots and lettuce were easily chopped up by the Bosch, so nothing gets stuck between the teeth. This was by no means the case with all of the smoothie mixers tested, including much more expensive ones. The Vitaboost can also get apples and pears small, including the core – the cores contain an enormous amount of nutrients, which is why you should confidently eat the whole fruit.
If you feel like something cold, you can simply mix some frozen fruit with the ice cream function and you have a creamy sorbet. Nut butter and nut milk preparation are also no problem with the Vitaboost.
In view of the very good smoothie result and the low price, the Bosch Vitaboost clearly offers us the best price-performance ratio of all the smoothie makers tested. Sometimes much more expensive models did not achieve such a good result.
