Question about Dyson DC23 Bagless Canister Cyclonic Vacuum
Had loss of suction on my Dyson DC23 vacuum which would go into a thermal shutdown eventually. I disconnected an elbow joint and found the clog. Once cleared, the vacuum is just like new again.

SOURCE: dyson 18 losing suction
Check the HEPA filter if it has one. This bit of foam gets clogged over time and significantly reduces the suction especially if you've been vacuuming a lot of very dusty areas i.e. dust from building work etc. Just wash the filter with lots of water and leave to dry before reinserting.

Might be the hepa filter needs cleaning? This is located in the housing on the side of the cleaner at the bottom (see your manual to find it). It is a big spongy ring which Dyson say you should remove once a month and wash in warm water. Dry off and replace in cleaner when completely dry. I've found this works and the suction is like that of a new machine!

SOURCE: No suction in upright position
Check the adapters at the bottom. They're supposed to move cleanly when you lower the handle. It's pretty obvious if there's an air gap when you lower the handle, and you should hear the suction in the air gap.
And...call Dyson...their support is great!

Following the advice of other posters, I unlocked and removed the gray plastic u-shaped "trap" at the bottom of the handle. As others have noted, there was a pen (red Sharpie to be exact), caught in there and that had led to additional blockage just like a sink trap.
Now I remove the u-shaped piece every other week or so just to make sure nothing is caught in there.

SOURCE: Loss of suction
There should be a sponge like filter in the area of the canister and no this is NOT the HEPA filter. When you find this other filter you will want to bang it off outside and then put it back in and you should be all set.
