Author Topic: DC25 Cyclone cleaning (Read 7461 times)

We got hold of a used DC25 that is working fine but smells horrid when running, like spoiled milk. After inspection the smell comes from gunk in the cyclone assembly. We have been able to strip that part on top (screws) and bottom (just snapping if off) and cleaning off all the smelly and sticky gunk there but there is still some inside that we cannot reach without removing the main rubber part from the cyclone plastic part.

I've wiped the bin and other parts with vinegar and vacuumed baking soda but as long as that gunk is in here we can't get rid of the smell. I'm talking about the part in the middle of that picture below (thanks for the stripdown guide!)

Any idea if this part can be dismantled or how to access the inside for thorough cleaning? Thanks!

Yes, we have seen that thread, this is where the picture I posted above comes from. It does not show how to dismantle that particular part, if it is possible...

The bit with the holes in clips off. But it is very tight and must be levered.

I'll see if I can get a pic tomorrow of one in bits.

Thanks for answering! We have not been able to clip off that part though, it is tight around the small holes at the bottom...

It comes apart by removing the rubber, then using a tool (or sometimes 2) like a switch removal tool to slide all the way around, rather like removing a bicycle tyre.

When it is off it looks like this:

But it is awkward and hard work to get it off to be honest.

Thanks for posting that new picture, this is exactly what we would need to do - if we could. I do not know what you mean by "removing the rubber" though... Going around the top part to pry it out we could manage but the bottom part around the smaller holes is definitely too tight. In desperation I have put it in the dishwasher, some gunk has been removed and the smell is lighter but still here. I intend to let it sit in water for several hours to hopefully soften the rest of the gunk and do another wash of it. If it fails we'll have to buy that cyclone part, can't believe the smell. Thank you for your time!
