Bosch MUM Serie 2 Food Processor Test: Suitable for Beginners, Limited for Insiders

Convenience of use

When we received the MUMS2EW40, we were first surprised by the large size of its box, because the robot-pastry chef is not one of the most massive in its category. Indeed, it measures only 26.6 cm in height and width for 27.7 cm in depth. For comparison, the Miogo MRPM1 knows how to impose itself in the kitchen with 36 cm in height and 30 cm in depth.

The Bosch can therefore easily sneak onto a work surface and the user can consider putting it away after each use; its weight of 3.7 kg is far from opposing this option. Fortunately, suction cups allow it to counterbalance its light weight and improve its stability and its good behavior on the worktop when it is used. The small bowl goes hand in hand with its size: it has a capacity of only 3.8 l, the lowest in our comparison after the KitchenAid Artisan Mini.

In the enormous packaging of the MUM Serie 2, it is therefore the accessories that take up space. Indeed, Bosch often offers its devices in batches and this model is no exception to the rule. If the reference MUMS2EW00 only includes the device, the MUMS2EW40 is properly accessorized. The robot comes with a pastry kit (whisk, kneader and flat beater), a blender, a multifunction bowl, a citrus press and a meat grinder. This versatility saves space for the user, who can therefore do without a large number of household appliances.

To attach these different appendages, the robot bends over backwards… literally. It has a 180° articulated arm, just like the MUM5. It can therefore bend down to accommodate tips on its back, on its head and on its back.

The accessories that make up the pastry kit are always attached under the robot’s head. Just insert them, then pull on them to remove them. This system seems simple at first glance, but is ultimately not the most practical. A bayonet attachment, similar to that of the Kenwood Titanium Chef Patissier XL, is preferable and avoids dirtying the worktop in the event of too sudden removal.

The flat beater stands out with its atypical shape. It is indeed composed of three arches, just like those of the balloon whip, which is not common. We will see if this configuration is as effective as a flat beater with a more classic silhouette, with a single hoop. It might have been wise to provide a second beater with soft edges, for example, such as the KitchenAid Artisan 5KSM175.

Getting started with the Bosch stand mixer shouldn’t be a problem. To control it, a large knob is located on the right side and allows the user to choose one of the four available speeds, or to engage the “boost” mode which gives a boost to the MUM’s engine. Series 2. On the left side, a button unlocks the robot’s head, which can pivot 90° up or down: it can therefore completely bend down or rise 180° in the end to accommodate a tip from the kit pastry or an additional accessory. If the handling is very simple, the opening of the head is not automatic and therefore requires the use of both hands. The Moulinex Masterchef Gourmet uses an automatic system that is much more practical for the user.

Like its friends, the MUM Serie 2 had to carry out a battery of preparations in order to assess its power, its speed of execution and the quality of the accessories.

Whisked egg whites

The famous suction cups that hold the device in place will be very useful during our test. After pouring 70 g of egg whites (about the equivalent of two whites), we equip the robot with the whisk and launch it at maximum power. The goal is to quickly whip the egg whites, without them falling.

The suction cups make it possible to counterbalance the featherweight of the robot and to improve its stability on the work surface.

If the Bosch robot obviously manages to mount the whites, it still requires 1 min 44 s when the Kenwood kMix, in the average of our comparison, ends this test in 1 min 20 s. The MUM Serie 2 is therefore a bit behind.

But if it is slower than others, it has the merit of obtaining firm whites which do not lose quality 15 minutes later. For example, we found 7.58 g of liquid white at the bottom of the Kenwood Titanium Chef Pâtissier XL tank.


The sponge cake test uses two accessories: the whisk and the flat beater. The first has the mission of abounding the eggs and the sugar, while the flat beater must correctly integrate the flour into this preparation.

The first accessory seems effective and makes the preparation grow. We are more wary of flat beater performance. Indeed, the blue food coloring does not integrate into the preparation and blocks of agglomerated flour cover the bottom of the bowl. We put the sponge cake in the oven and take it out 25 minutes later. Very difficult to unmold, it crumbles, especially because of lumps of flour. The sponge cake is obviously impossible to taste…

The sponge cake breaks into a thousand pieces.

This time, only the flat beater intervenes in the preparation of the shortcrust pastry. Slightly softened butter, we add the flour and start the robot at speed 1. The structure of the beater retains a few pieces of butter, which therefore do not mix with the rest of the preparation. The robot then obtains a crumble texture after only 3 minutes. The most efficient pastry robot on this exercise, the Kenwood Cooking Chef Experience, obtains a crumble in 1 min 12 s.

After 20 min of resting in the refrigerator, the dough has not gained in homogeneity; it crumbles and we then observe some butter residue.

Bread dough

Finally, comes the bread dough sturdiness and endurance test. The suction cups hold the robot down, and that’s fortunate, as we feel it could easily wobble without them. For its part, the engine keeps pace and does not seem to tire. It kneads for 8 min at minimum power at first, then maximum.

Before cooking, the dough reaches 6.40 cm, which places the MUM Serie 2 in the average of our comparison. Alas, everything crumbles when cooked. The bread then measures only 5.60 cm, against 8.1 cm for that made by Moulinex Wizzo. Above all, we are very disappointed with its texture: very compact and very moist, the bread is not pleasant to taste. Shame.
