Dyson aren't mean with their party-favours...

[vintagehoover]

I'm still working through all the film and photos from the launch yesterday; I have Sir James' 45-minute presentation to condense down into something which fits within YouTube's 10-minute video limit.

In the meantime, you may enjoy a preview of their latest technology - available to the public from 6th July, although it can be pre-ordered from their website now.

This is the brand new Dyson DC31; given away to all attendants of yesterday's event. This is the mid-range model, between the DC30 and the DC31 Animal. It will retail at £129.99.

It's a big improvement over the DC16. Most significant is the introduction of Dyson's new DDM V2 motor. Ten years in development, and protected by 15 patents, it is brushless, relying on an electronic chip to digitally switch between magnetic poles 3000 times a second. It's 1/3rd of the size of the conventional motor used in the DC16, and twice as efficient. It runs at 104,000rpm.

The new range of handheld models are the first vacuums on the UK market to use this new motor, but versions of the DDM can be found in the Airblade hand-dryer, the Japanese DC12, and the American DC22. The Japanese market in particular representing a 'dry run' for the DDM, Dyson are now happy enough with reliability and performance to introduce it on a larger scale.

Another improvement on the DC16 is the power and runtime of the DC31. On this model, Dyson gives you a choice; you now have 10 minutes use of the cleaner on 'normal power' @ 38 airwatts, or 6 minutes on 'intense power' @ 65 airwatts. The DC16 could only manage 6 minutes @ 38 airwatts. The power is constant, too - it doesn't trail off as you use it, staying at maximum output until the battery runs out.

The pre-motor filter needs washing once a month (depending on use). There is no post-motor filter - the DC31 doesn't need one, because it creates no carbon emissions!

Here are a few pics:













The 'intense clean' button - the light-up surround reminds you that you've boosted the power to 65 airwatts:

And just how small is the DDM V2? Here's the armature/bearing/impellor assembly:

hmmm

Although I do not care at all for Dysons, I do like the handhelds. Something different than your everyday dustbuster for a change.

Very, very interesting

Thank you for posting, I find this new technology to be immensely interesting, and the size of the motor is absolutely minute. To get that amount of suction power out of such a small size is quite amazing.

It is a credit to Dyson to launch the V2 DDM in Britain; I always presumed that Japan would get first shot at all the latest inventions.

I eagerly await all your photos/videos.

With regard to Youtube videos limited to 10 mins at a time: just post hundreds of unedited complete videos!!! LOL.

Thanks so much for putting those YouTube videos up Jack... Very interesting... Well presented.

I would not be surprised if Dyson were to completely move to the DDM in all their products... I have found my DC12plus with DDM to outperform a DC19... So much more power in such a tiny device

And another video - aren't you spoiled today?

As you can see, the noise isn't excessive, and pets just aren't bothered by it. Flora was completely disinterested (she's a dog, after all, she doesn't actively follow new advances in technology...), but Moses was quite keen to examine the dual-purpose nozzle!

I'm curious about digital motor machines

How are they going to make 'Allergy' machines with HEPA filters, now that the exhaust filter is redundant?

Does the HEPA filter now get shifted to the pre-motor position, or do Allergy machines still get two filters fitted as standard?

You would think that exhaust filters would help to muffle noise.

 

[vintagehoover]

The larger machines will have post-motor filters, just as the American and Japanese full-size DDM machines do.

With the American DC22 DDM, for example, the pre-motor filter only needs maintenance once every 7 years. The post-motor filter never needs attention.

 

[rolls_rapide]

the pre-motor filter only needs maintenance once every 7 yea

You would think that Dyson would move towards maintenance-free goods, rather than the current 'wash every 3-6 months'.

That would definately give them the edge over the competition.

 

[vintagehoover]

Well...surely once every 7 years is a step in the right direction? Can any other bagless vacuum match that? Can any other bagless cleaner even manage one year without filter maintenance? 6 months?

I mean, let's be realistic; I'm sure we'd all love a silent, weighless cleaner which vaporises dust as it goes, so you never have to empty it. With a pricetag of 99p.

But there are limits on what can be achieved!

 

[rolls_rapide]

No, what I'm saying is...

Where is the logic in launching DC22 with seven year maintenance intervals, when DC23, 24, 25, 26, 27, 28, 29, 30 & 31 have substantially more frequent maintenance intervals?

Surely successive machines build upon good design, incorporating the most advanced and best technology? No?

I get the distinct feeling that Dyson has several design teams all fighting against each other.

 

[vintagehoover]

None of the other models you've listed use the DDM, which I understand is the reason that the filters need such infrequent washing. I don't fully understand the physics behind it, when the DC22 DDM only generates 30 airwatts more than the standard, non-DDM DC22. And at 230 airwatts, the DC22 DDM is less powerful than other models, which require more regular filter washing.

As I keep saying, you really need to put these questions to Dyson. I can't answer them, and I doubt anyone else on this forum can or will!

 

[shanonabc]

I couldn't be bothered

GO TO DYSON!!

LOL

I will however chuck in that my 12plus' HEPA filter is still as white as the day I got it

 

[retardturtle]

but in reality, how long does it take to wash out a filter..a few minutes every 6 mos is no big deal. thats far better than most. as long as the thing works as it should the way it should then you got a winner...design teams against each other is nothing new...keeps ideas coming from all angles creative juices flowing,team a v/s team b...the best team wins and basks in glory...not to mention a prize $$$ im sure.

 

[rolls_rapide]

DC22 DDM is less powerful than other models, which require m

Then the longer intervals between filter washing must be down to the level 3 root cyclone arrangement. I wonder if the digital motor causes a superior airflow through the cyclones, allowing higher centrifugal forces to act upon dust particles.
