Dyson Radial Root Cyclone Doesn't Work Very Well!

[alexhoovers94]

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.

When I remove the filter you can see all the dust that has just passed straight through it and is in the very inner cyclone or in other words in the air path for passing through the motor!!

 

[alexhoovers94]

I thought I would show you how dirty the smaller cyclones are already, it has only been used normally.

 

[alexhoovers94]

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.

 

[alexhoovers94]

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!

That's funny, my Miele Cat & Dog has been in constant use for a month now. Bag is almost full and there's not a speck of dust inside the bag housing or on the pre-motor filter

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.

 

[dys0nb0y]

it's only a bit of dust and there is none on the filter going to the filter you be able to smell it.

 

[turbo500]

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.

 

[alexhoovers94]

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.

 

[dys0nb0y]

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.

 

[alexhoovers94]

Josh if it got there in the first place then more of it will come through.

 

[turbo500]

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.

 

[alexhoovers94]

I didn't even get that much dust through the cyclone on my Vortex when I tested it on a mountain of flour, no wonder Dyson sued them he knew that Hoover did it better and they always were better!

 

[turbo500]

For once, Alex, I agree with you! I always thought that the original Vortex was a FAR better machine than the DC01 and DC03 in just about every single way

 

[dys0nb0y]

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.
