That tech was launched over here some time ago, and makes it to the US apparently, though only in compact units.

en.letsgodigital.org/home-applia...


The idea of an element of the drum turning opposite to the rest of the drum and thus increasing mechanical action which allows for shorter wash times is nothing new.
First implication I can think of was the pulsator disc in some Hoover Keymatics (somewhat related to the Westinghouse FLs of the early times AFAIK).
Then came James Dyson in the early 2000s. Expensive and failure prone with a complicated planetary gear case on the back of the drum they weren't long lived.

Now Samsung is doing it, with the backplate of the machine turning.

On paper it works (EU standard cycles at 3h with incredible efficency for that time, normal Cottons cycle down to an hour, SuperSpeed at just 39min).

However it does add a lot of complicated components (second, independently controlled motor; a bearing somehow integrated into the achsel of the actual drum) in a verry small space.
Oh, and the few videos out there are of the spin cycle mostly and - for what ever bizarre reason - the back of the drum is static during that. Not sure if that might cause snagging, friction and tearing issues for the clothes.


What do you guys think?

Why reinvent the wheel over and over ?

H-axis washing has been around for about a century and it`s tried and proven in its lift and drop only action.
From what I gather here in the forum neither the Keymatics nor the Dysons were exactly easy on clothes nor worked very well.
It`s just another useless gimmick in my opinion just like the addwash door, the eco-bubbles, the 6 (or was it 8 ?) motions, the silver cold wash, a special cycle for shirts, jeans and pillows and so on. I don`t need any of this.
The 4 basic cycles (Normal, PP, Delicates, Wool) along with some options and variable spin speeds solved me every thinkable washing problem to perfection so far.
Only thing I miss at modern washers is an infinite temperature control.
I wonder if they finally gave up on that stupid idea of having a larger than 6 kg load in a standart cabinet we might not be bothered by those ridiculous long wash times and those questionable remedies like the Quickdrive.

Yes, the QuickDrive is also mentioned in Samsung's US press releases. I, too, was baffled to see the backplate stationary during the spin cycle. I guess, it'll move along with the laundry if the drum is full enough.

The Dyson

panthera's profile picture

Approach really cleaned very well - but it wasn't far removed from pounding clothes on stones in terms of wear and tear.

I had a neighbor with one in Munich. She's very much into 'design' and that Dyson does have. After two months of seeing really well made clothes disintegrate, she got rid of it and brought the Miele back up from the Keller. Actually, her husband, two sons and I brought it back up. Heavy beast!

End of the quick cycles, but just as clean clothes and no wear and tear.

All these ideas are interesting, but at some point it might be productive for manufacturers to do patent research and see what others have tried and consumers rejected in the past.

Methinks...

... it's a pile of mechanical bits just waiting to go wrong.

If Hoover sussed out that their pulsator was problematic in the Keymatic and subsequently disconnected it; and Dyson sussed out their own Contrarotator had issues and disengaged it, why on earth would Samsung's be any better?

From what I've read of previous Samsung machines, parts/service are in short supply or discontinued pretty quickly.

I would be concerned that thin cotton fabrics and lycra type materials might get trapped at the interface of the rear washplate and the rest of the drum.

Nah, like everything else in this world, the simplest ideas are best.

The simplest solution which meets all the needs of the problem set is the best.

I've been told ad nauseum that Millennials are destroying everything sacred and avoiding homes like the plague? Or simply unable to afford them, maybe ever.

I'm so confused.

imo I think the quickdrive is gonna be a fail and will make a bad reputation and i think Samsung are stealing ideas from dyson as it’s gonna be like how the dyson contrarotator was but imo i think the dyson contrarotator is much better than the new quickdrive machines

Quick Drive

I was looking at the 10kg model in John Lewis last week. I really like the control panel , the wash times are reasonable as is the build quality. They’re pricey though at just under £1600 and they have that awful cat flap add wash door.

Miele prices without Miele's quality.

I see they've also switched to 'in-drawer autodose dispensers'. Didn't the previous auto dose have a reservoir in the porthole area?


Post# 977658 , Reply# 13   1/9/2018 at 15:48 (220 days old) by henene4 (Germany)        

Tha porthole dosage system was only on the high end touscreen machine that had no dispenser drawer.

Intriguing idea, if they can keep it working.  Adding more mechanical layers usually ends badly, but points for effort.

> With more Millennials than ever buying homes

whatsername's profile picture
Off-topic but:
While the mere mention of millennials is able to send many members of this forum into fits, making me almost afraid to comment, I have to point out that "more millennials then ever buying homes" is basic statistics.

Millennials are regarded as the generation aged roughly 19-34. The national association of realtors reports that the median homebuyer's age is 36. Thus it's a simple deduction that almost half of homebuyers are millennials (we'll lump that extra two years in since generational division isn't an exact science), and that proportion is only going to grow as this generation starts families and the boomers' numbers start to dwindle.

That might lead you to ask why so many have been shrieking about millennials refusing to buy homes--and you would have a point. Here's the difference: that generation put off home buying much longer than other generations as they entered the "traditional" home buying age right as the housing market collapsed in 2008. (Remember that the upper limit of millennials would have been in their mid-twenties at the time, when previous generations were buying starter homes). The traditional arc of home ownership was buying a starter home, allowing it to appreciate for a few years, then upgrading, and so on. The subsequent recovery of the housing market in the past decade left millennials holding far less real estate capital than other generations--so now they have less leverage when it comes time to buy.

This difficulty is compounded by the fact that builders largely do not build starter homes as much as they used to as the profit margins are much lower than on luxury homes. Anyway, to make a long story short:
1. Yes, millennials are buying more homes than ever, because they make up a larger segment of the population than ever.
2. Fewer millennials are buying homes *proportionally*, relative to previous generations, and when they do decide to buy, it is later in life than older generations experienced, and they are buying homes they can stay in a long time, not really interested in constantly upgrading and "keeping up with the Joneses". And can you blame them?

Disclaimer: I am not a realtor, an economist, nor do I know anything about the real estate market outside of the US.

Oh dear,
It was me, lol.
I didn't mean to start crap.
Was just being sarcastic.
Making fun of how out of touch Samsung was.

A marketing gimmick

Ask any engineer what the first thing to fail in a system/machine will be and they will tell you its the moving parts.
The more moving parts the less reliable the machine.

These new mechanisms are like the filteration systems of yesteryear. A marketing gimmick.

They are unlikely to improve the cleaning performance of the appliance.

Back in the 1990s I worked for a company in the UK, who supplied components to Hotpoint.
We asked their R&D engineers which machine cleaned the best.
The answer: None of them.
They told us that it's the detergent that cleans your clothes. Not the machine.
The machine just provides the optimum environment to activate the detergent and move it through the clothes, so it can do its job.

If anything, shortening the cycle time will reduce wash performance as the detergent has less time to do that job.

The more contra-movements the greater the stress on the fabric.


Post# 997047 , Reply# 18   6/13/2018 at 07:52 by henene4 (Germany)        
Yeah

It's not the first time we have contrarotation.

Hoover Keymatic.

Dyson Contrarotator.

Now those.



As a engineer in the makein, yes, the more moving parts, the easier it breakes.
However given that from my knowledge these have basicly one motor and bearing more, and as all motors are brushless, I don't see how it will fail significantly more often.
The Dyson had a gearbox. As an engineer, you know you don't want gearboxes. They are complicated, they mean losses to friction, so just don't.


The stress issue was known with the Dyson machines.
The problem is overstretching the fabric.
Here, the backplate has no chance to stretch the laundry.
And you are overlooking that the washtime is significantly lower. The idea is to have an equal amount of mechanical action, in shorter time.

Actually, as a matter of fact, you are entirely wrong about the detergent claim.
You should know the "Sinnersche Kreis": Chemistry, temperature, mechanical action, time.
You can (in theory) minimize any component without compromises in cleaning as long as you proportionaly increase another component and do not entirely remove any one.
A 20-40min main wash is more then enough for enzymes to work, and as you only cut time, the mechanical action can own up for that.
And don't overlook that a lot of time is saved via their rinsing technology, simmilar to TurboWash and QuickPowerWash.

There are videos of it on Youtube already, and it works.
