Dyson Radial Root Cyclone Doesn't Work Very Well!

The hoover vortex was prone to motor failure due to the poor  filter catching the dust.


 





 


 


<span class="Apple-style-span" style="color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px; font-weight: normal;">I love these vacuums. I bought one when they first came out and in the first 12 months it had 6 new motors I also made my mum, cousin,and 2 friends but them despite the motor issues they were very good vacuums even if a little top heavy they picked up so much better than the dysons and groomed so much better I've had this one around 10 years and its just starting to make a few dodgy motor noises when you switch it off, but then it doesn't really get used so I'm not that worrie</span>

Is only a bit of dust and it's a lot better compared to other bagless vacuums keeping the dust in.

Josh, the heap filter is pretty clean, but that is not the point, the point is, the cyclone is not trapping this dust, if James's claims were to be accurate, the plastic housing around the filter would be clean and the filter would not be that dirty anyway as the Cyclone would of separated the dust properly.

Josh the Vortex was prone to motor failure due to tight and narrow air passages restricting the airflow, not fine dust, although in my experience from my Vortex when I got it, the motor was pretty clean inside and, it was used!

looking at the pictures there's not a lot of dust at the bottom so its not making it to the motor.

Alex, correct me if I'm wrong, but doesn't the air pass UP the filter with the suction channels being above it? Therefore dust nearer the top would indicate it is being sucked towards the motor?

 

[alexhoovers94]

not a lot now Josh, no, but what will it look like in 1,2 or 3 years? looking at my pictures, that is A LOT or dust passing through to the motor in JUST a week of daily use.

 

[dys0nb0y]

if the cyclones want traping the dust it would be a lot more dirty.and compared to other cyclonic machine it would be a lot more dirty.

Chris, the suction comes from the bottom of the bin sucking the air through the filter and through the cyclones, all the fine dust is supposed to be collected around the outside of where the filter is housed and of course all the larger particles are collected in the main bin.

in my opinion, the older Dyson models worked better as far as cyclone efficiency is concerned as the suction came from the top of the cyclone assembly, where as now, the suction comes from the bottom of he cyclone assembly.

So, because other bagless vacuums don't retain dust well, that suddenly makes it ok for Dyson to start blowing fine dust back out of the machine? I'm not buying that!




It sounds like Alex is disappointed with the actual cyclone set up, but for me, the biggest frustration would be the filter. Even if the cyclone did inevitably let some fine dust through, I would expect this to be captured on the inside of the filter. In my opinion, the biggest flaw is the poor seal between the filter and the cyclone, which is letting very fine dust particles through to accumulate on the outside of the filter housing and blow throw the machine and back into the air in use.


 


If this is the build up after just 1 week, what would it be like after a month, a year or 5 years? Alex is lucky, knowing what he knows about vacuums, he can intercept this fault before it becomes a problem, but your average user - even those who regularly maintain the filters - aren't going to concern themselves with this and it could become a problem later down the line if dust is regularly passing through the motor. Doesn't exactly make for a spotless home either.

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]

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.
