How to take apart and clean Dyson DC40 dust canister and vortex cyclones 

I really appreciate your videos. I was struggling to solve the red release button with the spring, however after viewing your video regarding this issue, it was easy to solve it and also the trick to disassemble all plastics and screen parts. You are smart and your videos are easy to understand and remember.

This is fantastic! I've had the desire to take it apart and clean the individual parts, I'm glad I never went for it because I'm sure I would've broken it. I would've been forceful, so glad for this video. ❤️❤️❤️ thank you for the video!

Legend!!! Simply blowing it out does nothing. Even with new filters, the stale dust smell still lingers and is probably why you found it dumped outside. Taking it apart like you have is the only way to avoid paying someone else to do the same. I've just done mine and it was disgusting inside, definitely the source of the smell. Thanks for showing me how to do it.

Awesome Video!! I think this has been the best tutorial video I have watched. You continued rolling through all the mistakes and that is what we need to see as I am sure I will encounter the same thing. I am glad you showed the part about the spring as I do not believe I would have even thought to rotate it. I am going to be doing my Dyson tonight. Thanks again for a Great Video!

I just washed the whole thing with water

You have saved me a lot of time with this video. So I won't have to gingerly take mine apart and destroy it in the process. Many thanks.

Excellent video I have just finished this on my sons Dyson.I made all the mistakes you made. Glad that the video showed them and how to resolve them. Thank you

I Followed Your Video 2 Years Ago For My DC40. I Used A Combination Of Air Compressor, Steam & Plastic Car Trim Removal Tools. A Bit Of Rubber Friendly Lube On Any Gaskets Will Help With Replacement. Cone Filter Can Be Rinsed For Cleaning But I Recommend Bottom (Ball Filter) Be Replaced Or Gently Blown Out With Air. To Date, It Is still Working As It Should. You Sir Are The Man And I thank You.

Awesome video, and great walk through step by step. Cannot thank you enough, last time I tried to open the cyclone part, but thought I might damage the plastic u til I came across your tutorial. Tha k you very much, subbed!

Thank you so much. I nearly ruined the gasket covering the top screws for the cyclone head but seen this video. I stupidly washed the cyclone with a hose pipe to clean the paint dust from it after connecting the sander to the hose. I thought it was clear after the wash but after taking the cyclone apart the holes were still blocked.

Thanks for the help! I found T15 torx to be a good fit for the screws, in case anyone wants to know. 😉

Great video. I've just sat on my kitchen floor and followed you step by step.

Really helpful, made me brave enough to attempt the job. Great suction when finished. Cool 😎

Great video. I really appreciate the fact that you left in the parts that didn't quite go to plan. They give a good indication of what to look out for. I was particularly interested to see the spring replacement. I had previously completed a DC41 overhaul following your guide and now this one for the DC40. Keep up the good work.

Really , really good guide ! I just got at DC 40 from my gf after her complaining that it did work very well so she went out and got another hoover. So pretty much followed step by step and the floor and myself where an utter mess !! No wonder it didn’t work very well as the filter was almost rock hard , also the little circle bit on the top of the cyclone where caked in dust pellets think there was about 5 still clear. Torque T15 bit was what I used to unscrew with something that was long enough to reach I say easily 20 cm . The only fiddly bits where the springs I found that with the red clip u best put it on and twist it before clipping back together and the little grey bit best to take off and leave till end . A simple flat head as long it’s got the spring in and facing the right go hand side will easily push back in . Easily half an hour to strip , hour to clean all parts then leave to dry over night and about half an hour to put back. The difference in the hoover now is night and day and I’ve pencilled in another deep clean service next year:)

A bit late to the party , pensioner neighbour was just out on her patio with a DC40 and she said it had stopped sucking , i looked at it and could see the internal pipe was all split , not the easy one , the one after that , so i have ordered her one as she was going to buy a new Vacuum ! Any way I brought it home and thought i would give it a good clean, the gauze was completely blocked and behind it was a few MM thick. The gauze is quite sturdy and i wire bushed it clean with a small soft wire brush.. Anyway I though how do you get behind the gauze.. you have helped so i will now take it off to clean . Thanks

So happy I was able to watch you do your vacuum first. Gives me complete confidence and taking my apart thank you very much

Thanks bootsowen very good video

Thank you very much for the time you spent putting together that video! You saved me a lot of time. I really do appreciate it!

Amazing watching you bravely taking that thing apart with a combination of strength and delicacy. You are incredibly patient.

Very good! Thanks!!!

This was super helpful up until the point just after the screw where you snap it back together. It wouldn’t snap back together no matter how hard I tried.. any suggestions please?

As others have said also … awesome video great to watch, learn n do - saved me a few £££!

Thanks

the blue cyclone can be blown out with compressed air. You do have to blow it out thru the screen when done.

Brilliant buddy . Very helpful indeed . Your persistance and patience shows that you can turn this dc40 back to a great working suction functional vacuum. Great video 👊👊

How long from start to finish did this take you approximately?

What's the screwdriver in the size you use

liked and subscribed as you taught me how to service my DC40

Great video, well shot and explained. I couldn't help noticing, at the end, you were wearing very large flares. National dress?

By far this was the best video on YT showing the disassembly, cleaning and reassembly of the Dyson DC vacuums. The camera work was excellent, I was able to see everything you did in detail. Thank you.

Can you do a refurbishment and then when you're done can you do a whole house video

Just had to make the effort to sign in to say thank you very much for taking the time to make the video. It helped me sooooo much in taking my (sh!te compared to the old ones) Dyson animal ball apart to its component parts to try and find out why the suction is sh!te, and why it actually BLOWS dust out when started up !! It was relatively clean inside, so will give it a try when the filters have dried out, and see how it goes. I'm glad I got to find out where the cyclone screws are, how to access them, how to get the two springs inserted before I had to try and find out for myself......a big thank you again 🙂

Really good very helpful

It held by seven screws in the cyclone

Fantastic video. Just what I needed.

This video was the best! Thanks

Greetings from Cleveland Ohio. Thank you so much for this video! A friend gave us one of these since it became to heavy for her and it needed a deep cleaning. Without your efforts shown here I know my level of frustration with the canister would have been pretty high. Anyway when I got into removing the screws to get to the cones I found seven screws to remove on mine not six like yours. The Vac is like new now. Best Wishes!

Very good tutorial. Easy to follow

excelled tutorial and addressed the problem I had with my DC 40. Thank you.

Good video , every now and then i clean mine through with a shower attachment in the bath with a quite powerful spray , the amount of dirt that comes out is amazing but i am never happy for long , two weeks or so later you get that smell again so i know i was not getting all the stuff out so thanks to your video i will now do it properly nice one .

Very good video. I'm amazed that all that dust gets trapped within the canister yet my filter is always clean when I rinse it.

My filter will not snap back on help !

I wish you were in Los Angeles, I'd bring you my DC40. 10-15 minutes into vacuuming, the 'note' of the motor changes and the suction drops off rapidly. The hose component won't even power up when it's locked vertical. (Are you in L.A.??)

it's a hybrid tesla no moving parts fluid valve x14

Brilliant, so easy to follow your steps and even some of your difficulties with the spring, I learned a lot and have just completed a good deep clean by watching you, pausing, watch a bit more, pause and copy etc etc. Thanks for time and knowledge,

I have the dc 50 and I blow the siclone with compress air

Best video on RU-vid I have watched..... thanks thanks thanks

Cool video man but washing machine brick

I’ve always thought the dc40 suction wasn’t great but you’ve done a good job there!

Great video Easy to follow instructions Thank you for taking your time to make this video

I have 40 vacuum

This is for the experts that you pay to maintain your Vac! Dyson does not advocate this for the consumer! he is a mechanic:)
