I dont have any pictures tbh, Mvacs might but the process is:
Open top filter lid
remove the washable filter
undo 2 torx screws
pull the cyclone out of the housing (note which way round it goes at this point, I'm sure it only goes back one way but something lines up to make it easier...)
Holding the resulting bit of cyclone by the shroud, give it a massive wollop on the pointy bottom of the cyclone on some carpet and the two should seperate (the shroud clips into a groove on the cone)
Remove the rubber seal from the cyclone cone but dont bother about the one around the edge of the cyclone housing, it's a pain to get back in!
Pop the outer cone out of the bin and remove its seal too
Small flatblade screwdriver to scrape the worse of the crap off, then wash with hot water (dishwasher, shower, sink etc)
Leave in hot place (airing cupboard etc) for a day, preferably so it catches the hot water a few times.
Dont bother trying to get the release valve out unless you feel brave, I always end up cracking the cyclone housing slightly. Bit of glue normally sorts it. Just blast it out with water as best you can
Re-assemble and voila, more suction I expect! Of course you could then strip the rest back down and wash:
Brushroll (pop the bearings out with the very end of the metal bar that runs through them)
brushroll end caps
clutch cover (remove the metal bar)
suction divert valve (squeeze the black palstic ring and it will pop off the clips
wand blockage valve
etc! Good luck!
