In detail missing from Series 48xx following functions:
- The intermediate switching stages have been removed, the machine has only 4 switching stages (previously 7)
- The practical moment level was removed, you have now for short operations with much force always out to step 4 and switch back
- No automatic parking position more: We must now bring the machine manually into park position, before you can remove the tool
- No operating level display with yellow or blue LEDs more, you can see the operating mode now only at the rotary switch (without illumination)
- The Kabelaufrollautomatik the 600W models has been removed, there are all only a simple cable storage compartment.
- The electronic speed control is not installed according to the manufacturer
- The rotary switch is now designed to be extremely soggy, the clean pressure points when shifting give it no longer (subjective impression)
Who wants all this have nevertheless, has to resort to a food processor of MUM5 series. The Bosch can, however, pay well, Moreover, most tools are incompatible - fit across all models only, which is connected directly to the kneading peg shaft (eg dough hook, beater, mincer). In addition, the diameter of the mixer attachment can not be removed at the MUM5 as the MUM4 for cleaning, but that's another topic.
Overall, therefore, there are only 2 star, although I have the appliance inspected, but never bought. I have, after the MUM47xx was no longer available, bought the MUM56S40 what after the technical downgrade the 4 Series is so willed by Bosch probably :-(
For the incompatibility of the tools you should really again deduct 2 stars, it looks but unfortunately with other manufacturers often no better.
