How do i switch my pool cleaner from pressure side to sucti

I currently have a pressure side pool cleaner; just brought 3 months ago from aquabot and it really remove dirt or dead algae at the bottom of my pool. But still I want a suction one from 'aquadist' which will work much better. Can I just buy the suction side cleaner and hook it up or do I have to change everything around?

I think it would be better if you ask your question in french

More seriously, don't you think that the filter size of your aquabot is bigger than particles you want to remove ?.
