I want to take apart the cyclone to clean the inside. Ive removed the handle (2 torx screws) and another torx screw from the upper part. But I still cant separate the upper part from the main body.
Anyone know how its done ?

As Jules has mentioned above, but I found that there are 2 additional screws INSIDE the housing anchored into the cover (penetrating the underneath of the cover). I had to dismantle the entire assembly to clean it, and these 2 additional screws had to be removed because they were holding the cover on. ie. to get access to the complicated white plastic moulding and the seals etc you need to remove SEVEN screws. Thanks Jules your help to get started was great.

Found this via a search on here...
Remove the 10cm / 4" long large funnel shaped section by gently pulling it off, ( its just clip fitted inside the larger piece which has all the hundreds of little holes in it.) Now you can access three screws which are Torx /Star type headed, to remove the section with all the little holes. You will then be able to see two more screws dep inside which hold the cyclone unit onto the top cover. Remove these 2 screws, turn the cover over and remove the 2 screws which hole the handle onto the cover. Finally carefully prise the handle sideways, its clipped onto the cover, to remove it and discover the last screw, making a total of 5 holding the cover on. This will give you access to a complicated white plastic moulding, which I recommend that you don't try to dismantle, but clean carefully with a bottle brush. Good luck, the only difficult part is unclipping the handle, but its worth it to have a really clean cyclone. Make sure that everything is TOTALLY DRY before you try to use it, otherwise the dust will stick and immediately block everything up again.
