    Features we love

    A snazzy build that lasts

    Because the body is made of strong metal, this model will give you many years of whisking, beating and kneading. It’s really easy to clean too, since it has a smooth surface. So, not only does it look great on your countertop, but it’s really durable. Not just a pretty face.

    Smooth mixtures in a flash

    You’ll always have speedy results with this extra-powerful motor. If you love baking, it easily cuts through batter and dough, so making cakes with the kids is a doddle. And when it comes to more complicated recipes, it can handle a large volume of ingredients too, thanks to the roomy 5.5 litre bowl.

    Weigh as you go

    Save on time and kitchen space, as this mixer has weighing scales built-in. Instead of having to weigh your ingredients separately, you can measure them as you go along, and you won’t need to clean out another bowl either. It comes with a handy timer too, so you can prep other ingredients and keep an eye on the time.

    Nothing gets lost in orbit

    Whether it’s a whisking, beating or kneading, the planetary mixing action imitates what you would do by hand without all that effort. And because it moves in 3 directions at the same time all your ingredients are mixed together really well, scraping every drop off the sides.

    Perfect results with the touch of a button

    Get perfectly whipped egg whites at the touch of a button. The clever SensorControl Plus automatic programmes take the guess work out of baking and do all the hard work for you. And you don’t need to keep an eye on it either – so go on and put your feet up while it works its magic.

    Thoroughly recommended.

    Well built and sturdy, quality product. It was surprisingly easy to get to know the operation of the scales and timer functions. We went for this as it seemed like a powerful model with 1500w rating, and we were not disappointed. The cable auto wind is such a useful addition and removes the annoyance of having to gather the cable once finished or hide the extra length when in use. You only need to pull out as much cable as needed to connect to socket. It is fairly quiet in operation compared to others we have tried in the past. The included accessories are a good start for our mixer as we are much pleased and intend to add to the accessories collection. The liquidiser jug is very well built with thick glass. The chopping discs are ok, and will replace our current food processor. This is such a wonderful item and I'm sure will be the centre piece of our kitchen, replacing a number of separate items we have at the moment. Thoroughly recommended.

    Really like the integrated scale. It safes me a lot of time.

    Sturdy and works well so far.

    Great mixer but one problem

    I bought this mixer at the end of February as I have always wanted a stand mixer. The mixer itself works great, it whips cream really well, it kneads dough well and the cakes were great. BUT....I have only used the mixer four times and the silver writing on the touch screen has come off. I only wiped the screen clean with dry kitchen paper (only had some flour and icing sugar dust on it and never got wet). For this reason I have marked a 3/5. When calling Bosch, they directed me to AO and classed the fault as "cosmetic" so not under manufacturers warranty. I was surprised at this as it is a new model but if that is their policy then fair enough. AO were very helpful, at first offered some money back and for me to keep the mixer but I declined and accepted a full refund - thank you AO! For such an expensive item, I would have expected a better response from Bosch and also something like this to be identified in the testing phase.

    Fantastic Mixer!

    Probably the best mixer I have purchased! I have 3 Kitchen Aids too but thought I would try this one. This mixer is now my go to and the others are the back ups. The weighing feature is so helpful and the mix speeds are perfect. I own my own bakery and the icing mix now is silky and smooth.

    The best mixer processor I have used.

    The OptiMUM9 with it's 1500w motor has the most speed controls I have seen and used with the optimum pre-sets making it so easy to use for everyday use, and the whisk attachment has a height adjustment should you need it. Having a grater / shredder by a simple attachment which delivers it's product straight into the mixing bowl so you can even weigh it if required makes so much sense. The blender is made of glass and not plastic with a good sized capacity so it will not stain as some others do. 5 stars all the way, I couldn't fault it..

    Engineered and quiet, solid performer.

    My well-loved combination mixer / blender / food processor of 34 years passed on (after my Partner left it unattended and it fell off the countertop). 34 years of good German engineering. A replacement was researched and found in the Optimum 9. After a month's use, we note: # A well-engineered machine, quite heavy and very solid. # My Partner who makes bread is impressed with the scales and has noted it turns out great bread dough. # The stainless-steel bowl is big and fits a large quantity of ingredients. # Easy to use and assembly, if somewhat heavy. Needs cupboard space for all the attachments we have purchased. # At time of writing, we are struggling to obtain some of the additional attachments to add to the functionality of the machine, but we suspect this is due to the impact of Covid-19 and hope to add to the functionality shortly. # Slightly disappointed that some of the stainless steel and plastic parts are not recommended as dishwasher safe. Post covid to "use, load, wash and go" is important in our busy working lives. Before buying we had the impression from the Bosch website that it was all dishwasher safe. # Very quiet and smooth operation. # Unlike other Bosch appliances I have bought, disappointed not to have a recipe book or website with hints and tips using the machine or YouTube videos. Particularly kitchen shortcuts (e.g., found one review which recommended using one attachment to shed cooked chicken for Asian inspired dishes and sandwiches). Please Bosch have your kitchen scientists research and share shortcuts to creating fabulous dishes in short time for everyday cooking.
