A Bit Bored, so I Wrote This!
I just wanted to say this, but I hope this has not been written here already or elsewhere, but this is basically how the Dyson washing machine works in terms of their wash action. (This is all off the top of my head, so my apologies if I miss some bits out, etc.

I also know many of you know much of this anyway – I’m just a bit bored and want to ‘exercise’ my brain for once!

)
In a normal washing machine, the clothes tumble (rise and fall) of course. There is some agitation, as there is movement and the clothes rub against each other and the drum. Add in a water jet (e.g. Jetsystem) and you have ever more ‘actions’.
The way the Dyson washing machine works is this:
With contrarotating drums – and this only applies at certain stages of the cycle, as the Dyson will work normally at times, as shown in David’s videos – the two drums turn in opposite directions. What this effectively does is twist and flex the fabric, which can allow a better method of washing over a traditional tumbling action. Dyson conducted many tests (rigs) to ascertain what they found was the best way o getting clothes clean.
What Dyson found during their tests was that this twist and flex action is very similar to hand washing. Indeed, if I remember correctly, hand washing is what Dyson tried in order to see just how effective hand washing was, and it was their belief that trying to get an automatic washing machine to mimic hand washing would most likely produce the best results. That is, in effect, what a Dyson washing machine does – hand washing in an automatic washing machine! Other ways of washing tried during testing, I believe, included punching clothes to see if that would work well! (Sounds a bit like “Beats as it sweeps as it cleans”! hehe

)
Other issues that Dyson wanted to tackle included the dispenser, which has no seal on other machines (as far as I am aware). However, the Dyson’s dispenser does have a seal to prevent leaks. This, still, is a rather silly omission, and I believe some engineers still express concerns at the lack of a seal on an area of a washing machine that could – and does! – leak. No area of any plumbed-in appliance should be without some form of appropriate seal to prevent flooding.
This leads me on to the door seal, which is quite different in Dyson washing machines. If I remember correctly, this was designed to reduce odours and mould, and Dyson made it quite different to other machines in many respects.
The large capacity was a selling point when the machines appeared. I know my Mum wanted one, as did I, because of the large capacity and unique features. I had all the brochures and tried to learn as much about them as I could. Sadly, before we could get one – and I was saving up – Dyson ceased manufacture, which I think was a great shame. Yes, like anything, they have their issues and perhaps weaknesses, but we felt a Dyson would have been the machine for us. They may have had their faults that had to be corrected, but at least Dyson did correct them for customers.
What we had to get instead was a Miele, which we are very pleased with.

If I could, I would have a Dyson as well!
Correct me, David, or anyone else if I’ve got this wrong!
