Hello Maggie, I would be happy to help you differentiate between the Braun MultiQuick models.

The main differences between the models lie in their performance and functions:

- Power: The Braun MultiQuick 9 (MQ9187XLI) has a power of 1200 watts, which makes it one of the most powerful models. The other models may have different wattages, but specific information is missing.

- Functions: The MultiQuick 9 has advanced technologies such as Active PowerDrive and ActiveBlade, which ensure finer and faster results. It also offers a pulse function and different speed modes.

- Accessories: The number and type of attachments supplied may vary depending on the model. The MultiQuick 9 comes with an extensive range of accessories such as dough hooks and whisks.

For detailed information on the 9147 and 9187XL models, I recommend consulting the official Braun website or contacting Braun directly.

Multi Quick 9 is the model series. The basic appliance is the same and the difference lies in the accessories: the 9187XLI has one more large food processor attachment.
