The "extra" "only" has a timer, time setting according to recipes. (was enough for me) The "genius" has 9 programmes and is therefore more convenient in terms of settings, and also switches off automatically. The "genius 2in1" also has a separate, attachable basket for additional, simultaneous food preparation.

The Extra I bought only has an on/off switch and a timer. However, the timer does not switch the appliance off but only functions as an "alarm clock". It looks like the Genius has a lot more functions...
