I recently bought a Dyson DC40 Animal and have been using it for about a week and already I have noticed the cyclones are not capturing the dust properly as Dyson claim they do!

I took these photos so you can see what I mean.

The first photo shows you the Cyclone with the filter in place, which looks pretty clean still.

and if you look at the ducting that goes to the motor, you can see some fine dusting beginning to build up around it, meaning this dust is passing through the motor, not what I was expecting because of all the strong claims, I feel cheated!

Have you noticed any lack of suction? Or dust escaping into the air while you vacuum? That sure does look dirty!!
 
that's weird it doesn't happen a lot.make sure your don't overfill it.my friend has a dyson dc40 and it's about 4-5 months old and its use everyday i have 5 people live in the house and 2 dogs and the whole house is carpeted and the filters are still clean.maybe get dyson to send you a new cyclone as there might be a problem with yours/

but of course it is gonna get dirty but compared to other vacuums it doesn't let through stuff like dust and hair like other cyclonic vacuums.but it's been picking up a lot in one go is gonna get dusty quick.
 
I have emptied it after every use as I would do with any bagless vacuum. The filter is still clean but the dust that is not being captured by the cyclone must be passing straight through the filter as it is not very dense.
I have noticed that all the dirt raises up to the shroud when the hose is blocked off for any reason, and that would cause a lot more fine dust to pass into the inner cyclones.

I wish someone would tell James Dyson to give it a rest and say hello to the bag again!! The back filters better as well as capturing more dirt than a bagless and todays synthetic bags don't tend to loose any suction.

What a waste of money this machines is!
 
even though its got dust on the cyclones it still won't lose suction.but it won't get any dirtier than that.that's accumulated around the bottom seal that's just where you take the bin off static will make the dust stick to it. so it's not actually going through is just static.
 
it's only a bit of dust and there is none on the filter going to the filter you be able to smell it.
 
Personally, I wouldn't want all that fine dust blowing back out into the room. If it's getting past the main HEPA filter, it will easily blow through the motor and back out into the room.


 


Reading this, I'm far more confident that as much dust as possible is being retained in my vacuum, sealed in the bag and thrown away, instead of blowing back out of the machine. And that's not taking into consideration the inevitable dust cloud when emptying the bin.
 
Josh I feel like you are justifying it, it seems like Dysons newest cyclone are no more efficient than the DC01!
I personally thing the setup of the filter in a flaw in the DC40, DC41 and DC50.
 
who said it was being blown back in the room.as if it was you be able to smell it.and alex this is completely fine for my personal experience it's just the light coating and won't get any worse.and is not going to the motor this just where static builds up and make it stick.
 
You'd be able to SMELL fine dust, would you? Tell me, what exactly do fine dust particles smell of? Because fine dust is everywhere, all the time. It's unavoidable. And I'm willing to bet you don't walk into your living room or bedroom and think "my gosh, it smells like dust in here!".


 


If it weren't for the fact that you can actually see it building up outside of the filter, Alex wouldn't even realise that it was letting dust out.

The fact that this dust is on the outside of the filter shows a. that the cyclone isn't as efficient as Mr. Dyson claims. If it was, this level of build up wouldn't happen after just 1 week. And B. that the filters aren't as efficient as Mr. D claims because if they were, this dust would trapped on the inside of the filter and not on the plastic of the machine outside the filter.

Obviously quite a poor seal between the filter and the cyclone which is letting the dust through. This is all dust that the filter should trap. No wonder the filter on Josh's is so clean if it's all building up around the outside of the filter.
 
so just because a bit of dust has built up its flawed and all new dysons with filters are flawed.so if the dust was going through the filter it would be on the hepa filter so alex so can you show the hepa filter.
 
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?
 
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.
 
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.
