Find the best all-in-one kitchen machine

How does the expensive Thermomix compare to the rest?

Who needs a bench full of clumsy kitchen contraptions to chop, beat, mix, whip, grind, knead, mince, grate, juice, blend, heat, stir and steam, when you can get a single, overachieving multi-functional unit that does it all? They're an automatic, set and forget system that's almost as good as having someone cook for you. They come equipped with safety mechanisms but with recent reports of exploding machines and burns from hot food, just how safe are these wonder machines?

Thermomix update

Some TM31 models are subject to a 2014 recall due to a faulty sealing ring which has been linked to more than a few serious burns and hospitalisation (this model was discontinued in late 2014 and replaced with the TM5). Affected customers should have been sent a replacement, but all Thermomix users should check the ring regularly for wear and tear, and replace it every two years.

Thermomix in Australia was fined $4.6 million in April 2018 for misleading customers about the burn risks of their TM31 model. CHOICE found the TM5 Thermomix to be an excellent all-in-one kitchen machine but we suspended our recommendation due to substandard customer care. 

Safe use

The recent reports surrounding the Thermomix has highlighted how important it is to use these appliances safely and to familiarise yourself with their safety features. It's prompted CHOICE to look further into the safety mechanisms of each machine and where we find they don't stack up in terms of safety we won't recommend them. Some important safety features to be aware of:

Speed cut out over 60°C

When cooking in these machines at high temperatures it's important that they are equipped with a speed cut out system that doesn't allow you to apply high speeds (or automatically reduces the speed) when the temperature inside the bowl is above 60°C.

If a machine doesn't have this feature we won't recommend it.

Lid lock

Most machines won't operate unless the lid is locked into the main unit. Taking care of the lid's rubber seal is also important as it's required to securely attach the lid to the  jug/bowl.  You'll eventually need to replace the seal as over time the rubber will begin to deteriorate and won't work as effectively to seal the lid. In most models the seal is removable for cleaning and while many manufacturers say it can be cleaned in the dishwasher, we'd recommend against this. The chemicals in dishwashing liquid can deteriorate the sealing ring quickly and cause issues with the lid not sealing correctly. If the seal isn't right it could result in possible unlocking during processing and the lid coming off.  

Measuring cup lock

All models have a measuring cup that sits in the hole of the lid. In some machines the cup locks into the lid (with vents around the cap to allow steam to escape) while in others it sits loosely, can rattle and if pressure builds up can create a situation where hot liquid could spill out.

 What else do I need to know?


Most all-in-ones are fairly noisy at high speeds, and only a little less noisy at low speeds – you might want to test it out in the shop before you commit.

Exterior temperature

Some bowls can get pretty hot during cooking so handle with care!


The controls should be easy to use and comprehend with clear labelling and/or bright digital display.

Inbuilt scale

This allows you to weigh food as you go.


The instructions should be detailed and comprehensive, especially if you haven't used this type of appliance before. They should also come with a range of recipes to get you started.


As few attachments as possible makes storage easier and cooking simpler.


Look for comfortable handles that are well-insulated. The handles can get hot after long cooking periods and the bowls can get heavy with a full load.


The surfaces should be easy to clean, with few cracks and crevices where food can become trapped.


All-in-one kitchen machines can range in price from $300 right up to $3300.
