Have a look at the MIELE homepage at
https://www.miele.ch/de... - you'll find it there (of course only for the models offered by MIELE Switzerland, not for models imported from other countries) - what seems important to me are the differences in the additional battery and the electric brushes - you'll just have to see for yourself what you need). Personally, I find the Triflex very good, the power is really strong, only the emptying needs some practice... I hope this helps! Greetings Peter
