The accessories for the Bosch MUM 4 food processor range are in many cases compatible with the MUM 4405 model, but there are some specific considerations to bear in mind.

- Some spare parts and accessories, such as the mixing bowl lid or the dough hook, are often compatible with several models in the MUM range, including the MUM 4405.
- Specific parts such as the scraper dough deflector of the dough hook are explicitly compatible for the MUM4405JP model, which indicates that they may also fit the MUM 4405.
- However, it is important to check the compatibility of each specific accessory, as not all parts fit universally. It is advisable to consult the manufacturer's designation and the list of compatible appliances to ensure that the selected accessory will fit.
