Dyson Radial Root Cyclone Doesn't Work Very Well!

[dys0nb0y]

Is very unlikely or getting worse.is just the first week so maybe continue to use it and if it gets any worse i think i contact dyson as they might be something wrong with it as is quite unusual.maybe the cyclones are kicking in and mybt get better after time.here's a pic of a 1 and a half year old dyson dc41 used everyday and the and thevfilter has never been cleaned.and the hepa filter is still completely clean just carbon dust on it[this post was last edited: 2/1/2015-18:12]

Thanks for confirming, Alex, I couldn't remember exactly what the set up was like on these.

 

[alexhoovers94]

That filter looks pretty clogged, not working very well, if the cyclone separated this, then why would it be building up on the filter and filter housing. if it worked properly, it would not need a filter.

 

[dys0nb0y]

i don't think alex said it was blowing out dust.

 

[dys0nb0y]

well of course you end up dirty if you wanted one that doesn't have a filter you should of save waiting for the price to go down and got the kineti.the filter is still kind of clean is machine is older than a year and it's never been washed and it still got its full suction.even though it was there until i told her.

 

[alexhoovers94]

This is what I would expect when removing the pre filter

 

[turbo500]

Josh, yours is doing the same. The filter chamber has a layer of fine dust all the way around it that neither the filter or the cyclone is capturing. Obviously not just a fault with Alex's DC40.

 

[dys0nb0y]

not mine it's a ladies .and it is about 2 years old now.[this post was last edited: 2/1/2015-18:16]

 

[dys0nb0y]

if a lot dust was going to the motor you would see some of it in the hepa filter.

Well Alex, you have put me off getting a new Dyson to test. I think you should make a video of your findings and make a noise on Dyson's Facebook page regarding the dust getting passed the cyclones and filter.

Like Chris, I have never noticed any dust in the bag compartment of my Miele cleaners, proving that the bag is doing its job and retaining the majority of the dust particles before they reach the motor and finally the exhaust filter.

I would return the cleaner to Dyson if you are not happy with it.

 

[fantomlightning]

They all seem to do this...

The DC39 I have to clean other machines had it's filter covered in grit, never fine dust for some reason but grit. My DC50 with the newer dual tier cyclones looks exactly the same as your DC40. I wish I could get a Fantom again, filtration wasn't the best, but the canister held and compressed way more dirt than the current Dysons do.

 

[marcusprit]

I am very surprised at this i've not had this problem with my DC41. I would contact Dyson and get a refund. There should not be any noticeable dust escaping from the cyclones.

 

[marcusprit]

Btw how can the filter still be clean if dust is passing through it? That is not possible. I've just taken my filter out and looked inside and it's still very clean. That's very strange.

 

[marcusprit]

Here is a photo of motor inlet after 4 months use and it hasn't been cleaned. Spotless.

Wow.
The pre filter may have let dust through but it is still most likely gonna expel air 150X cleaner than the air you breathe. The HEPA filter is a good filter. Check the dust coming from there. I am sure there is not any dust going back into the room.

The motor won't fail, I used my DC08 Origin for loads of plaster dust without the pre motor filter. I then left it outside for 4 months. Took it home after that and it still worked.

TBH that pre filter is quite thin compared to the DC07 and 14 models. The motors on them have little dust after years and years of use. If I were to modify that, I would cut out a long sponge and put it in the top of the filter.

I wouldn't be surprised of a DC33 had a dusty motor cos it dont have a filter as thick as the DC07 and 14.

I think the best cyclone system on a Dyson would be the DC07 de rooted models. Our DC07 Origin has a Derooted cyclone and the filter stayed spotless after 6 months! There was not even a hair on it.

 

[parwaz786]

My mates DC41 from 2012 didnt even have it looking like that after a years worth of use.

I think you might have a one off, Alex though. I could be wrong. But maybe it requires a new part even thought is a week old from new.

A neighbour a few doors away has a DC40 which he is happy with and though he does wash the filters on it, its fine.

 

[marcusprit]

If the filter is clean that cud be dust blowing back when you empty the bin. If that much dust was escaping from the cyclones the filter wud be filthy.

 

[parwaz786]

Yeah! Mark has a point. Dust clouds happen from emptying bagless vacs, so it might have gone up the tube. Maybe the filter is not to fault

 

[marcusprit]

Yes that's wat it is dust blowing back. Dyson are not that stupid to take a backward step and produce inferior cyclones.As much as some people wud love to think they have. Haha

 

[marcusprit]

Filter after 4 months use and not washed
Spotless! If that much dust was escaping cyclones it would be filthy.

 

[marcusprit]

My advice would be to arrange for a Dyson engineer to call and he van explain what is happening. There is no way that much dust will escape the cyclones.

 

[turbo500]

I still think it's a problem with the seal on the filter. All that fine dust should be captured by the filter, but because of the poor seal between the cyclones and the filter, air is passing around the sides of the filter rather than through it, causing very fine particles of dust to bypass the filter altogether. The filter isn't filthy because it's only very small particles that would normally embed into the filter material and not pass through to the other side, but it's showing up on the plastic because it's non-porus and a darker colour.

 

[marcusprit]

Why is the motor housing spotless in my photo then Chris if dust was passing the seal it would be covered in dust. It is actually a very good seal.Give Dyson some credit they are not fools. Some people on here I'm not so sure about.

 

[marcusprit]

Anyway I vowed not to argue about vacuum cleaners anymore but when some members spout rubbish I can't help myself!

 

[turbo500]

Not that good if it's letting fine dust through, is it?


 


It's quite obviously a problem on Alex's DC40 AND the DC41 that Josh has posted above as both have dust around the OUTSIDE of the filter and on the airducts going into the motor.


 


It's so amusing that even when presented with photo evidence of a flawed design, people still think they can argue the toss about it.

 

[marcusprit]

Haha have you looked at my photos? Its very amusing when someone on here thinks he knows better than Dyson scientists. Utter nonsense. There is no more dust escaping the cyclones than escapes the Miele or sebo bag. Look at the evidence in my motor inlet photo where's the dust Chris? Haha plus would they produce Cinetic if so much dust was escaping the cyclones and ruining the motor after a short period? Oh please come on? Hahahaha

http://?

 

[marcusprit]

Anyway there's no point arguing with a know it all who hasn't even used the latest Dysons he just goes on hearsay.

 

[turbo500]

We're not even talking about the Cinnetic, so god only knows what conversation you're having. The cinnetic is a completely different design with no relevance to this discussion.


 


Yes, I've looked at your photos. I've also looked at the photos provided by 2 other people - Josh with a DC41 and the original post by Alex on the DC40. So you're outnumbered, I'm afraid. We also have no evidence that you didn't wipe your cleaner out before you took the photo to save face, which wouldn't suprise me in the slightest.


 


It's also important to note that you have a DC41mk2. The other 2 cleaners shown are a DC40 and DC41, so (unnervingly giving you the benefit of the doubt) this is potentially a problem that has been sorted on newer models. But as both the 40 and 41 are still on sale, I'd say it's still very much an issue.


 


And as I've said before, whilst I haven't used the DC41mk2, I HAVE used the DC40 and DC41 enough to form an opinion.


 


We all know who throws his toys out of his pram because he can't take criticsm, even when presented with photo evidence.

 

[marcusprit]

Excuse me but I do not tell lies! It has not been wiped and you wud still see dust inside as I'm not gonna dismantle the ball. Anyway keep spouting your nonsense I go on my own personal use of a product unlike some others.

 

[alexhoovers94]

I think I am going to send it back...should of known better!!

It is not the fact that it lets dust through the filter, it is the fact that James Dyson is making false claims with my money!

I can't fault it's performace but it is flimsy and as has been proven doesn't work very well.
