This is the cyclone unit from a Dyson DC27, that the owner wanted me to have a look at and clean it up

Firstly, seperate the bin from the cyclone

The bottom flap comes off the bin by squeezing the bin udner your arm until the tabs pop out

The release rod pulls out of the bin assembly

And the seal comes off the bottom flap

Onto the cyclone now. The cone pops out very easily from the bottom of the shroud

and the bottom seal pulls off the cone

Onto the top now

The bin release button pops out of the handle

removing the 7 screws removes the top cover

2 screws on the handle enables the handle to be removed

7 further screws hold the seal housing onto the cyclone unit

which can be removed and reveals a VERY worn cyclone seal

Several locking tabs release the shroud from the cones

The middle part of the bin release flap can be removed now

this seal sits between the two halfs

This springs out of the release button for the bin

And she is apart!

All washed and cleaned, it can be re-assembled

Rubber seal back into the shroud

put the spring back onto the release button

and bring the two halfs back together. The spring can be a bit tricky to get in place, but it gets there. Dont forget the middle part of the release rod!

The very worn cyclone top seal is palced carefully back into the top cap

and screwed down

top seal for the bin is refitted now

Top handle screwed back down

Top part of the release rod pushed home

Top lid screwed down

Bottom rubber onto the cone end

and the cone can be refitted to the shroud

Outer seal refitted to the bottom cyclone flap

last part of the release rod can be fitted to the bin

Bottom flap can be bought home to the bin

and once the bin is refitted to the cyclone, the job is done!

If you have reduced performance, and new filters, checking for blockage and cleaning all the rubber seals you can see don't fix it, this might be your answer!

You might have replaced that worn rubber gasket.

She wouldn't pay me to do that! Wanted to do a full refurb as the machine was utterly ruined, struggled to get £20 out of her for a cable repair and changeover valve fix, did the cyclone because I was bored!
