I don't think I have ever known one, but if not does anyone know why? Is it to do with the Cyclones or anything?

A lower power? That would make them worse...well, can they get any worse?

Im sure their cylinder vacs had variable power at some point. Doesn't the DC19 have variable suction?

Nope, the DC19 does not, along with every other dyson as far as I'm aware!!

Dyson did use a two speed YDK motor in the DC04 Zorbster. When the clear bin was removed, the machine fan on "lo" speed to scrub in the powder.

In what universe?

There hasn't been..

Any UK models with variable power..

Just a suction release trigger on the handles of the cylinders I think.

I've always wondered if it was to do with the cyclones, meaning that at low power the cyclones wouldn't separate dust as efficiently. ? Hmmm.

It's not until recently that I have understood the need for variable power. I used to want high suction at all times. But low power equals low noise, which is important for midnight cleaning!

I'm not sure if I remember seeing some Chinese models with variable power. I know they have models that have the power switch on the handle (on the cylinder machines) can't confirm whether I remember a plus and a minus on there too.

Did the DC12 in Japan have a 2 speed motor?

As has been said, the closest to variable power is the 2-speed Zorbster.

James Dyson has said in one of his books how much he disliked gimmicks and buttons (or at least words to this effect), hence why his uprights have never had a foot release pedal.

Dyson thinks that an air control on the hose is enough to adjust suction power.

Take a look at the Hose cuffs on certain Dyson uprights like the DC07 and DC14. they have holes, so you can push the tools in all the way, or just a bit. The airflow holes in the crevice and stair tools also help with this.
The Dyson handheld models after the DC30 (not DC16) have a boost button.
The Dyson DC04 clutched model's hose cuff has a semi-circle release button for the wand, and a circular button for suction reduction.
The Dyson DC01 and DC03 for example didn't need this.
The Dyson cylinders, however have a manual suction release valve which the user can optionally choose to reduce the suction or not, again similar to the DC04 clutched model's hosecuffs.
The Dyson DC12 does not have an electronic suction reduction feature.

Is that for 2-speeds though, or is it for switching on & off the brushes (or similar)?

Well...

The turbine brush looked like it was air driven and the DC39 was the first dyson to have air turbo head on/off. I watched a video of a DC12 and the lady using it was able to make the suction increase...

Actually, I think I mzy be wrong about the DC12, the buttons may be for the suction!


Dyson handhelds on the other hand, have the boost button which increases the motor speed so it makes the entire vacuum including the brushbar have more power, but shame that it's only 6 mins

dc12 2 speed

to me that looks like a filter light, on green it is fine on orange you wash the filters and on red you call the helpline as clearly shown by the little images above each shade of light

Dc22

In the states we had the compact canister called the dc22 with the brushless motor that had two speed. However at $800 it was expensive and small.

The effectiveness of the cyclones depends on air speed, so decreasing the speed would make them less effective.

The cylinder machines in Japan and DDM motors have 2 speeds, high & low. This was controlled via the handle. It's never been available in the UK, we only get suction release triggers. The turbine heads work using suction valve cut off system to allow the brush to go off.

James Dyson said many things in his book. He says things what people want to hear. Dyson DC18, DC15, DC24 and DC25's all had foot pedals to release the machines! I recalled Mr Dyson saying that he doesn't need to do TV adverts. They have been doing adverts for years.

Dyson also claimed that their machines had suction release valves to provide automatic suction control and protect children when all the valve was there for is to allow continuous airflow when the nozzle is blocked over or the crevice nozzle is in use as the cyclones need constant airflow to keep working. Mr Dyson is very clever with his words.

Dyson claim their new Cinetic machine never loses suction as it doesn't have filters to wash or replace. All my Dysons in the past and my current DC24 filter blocks up with dust so maybe it lost some suction. With use?!! A warning is on the Cinetic machine under the bin not to use it on plaster dust, rumble and the like.

My DC22 Motorhead is 2 speed, high and low. I think that was all they ever did, not aware of any variable speed Dyson.

My Pink DC22 Digital Motor Canister vacuum has two speeds to it, I can take a picture of it and post on here once I get back from my business trip.

"Dyson DC18, DC15, DC24 and DC25's all had foot pedals to release the machines!"

Sorry, I forgot all about that when I wrote what I did. Yes, you are quite right, they do. But I know -based on what I read- that Mr D was against the idea originally. It's funny, because whilst he doesn't like gimmicks in one form, he thrives on them in another. For instance, the new turbo head which can be switch off and on via an air-release in the handle. A foot switch would have done the job, but that wouldn't require much R&D. Goodness knows I could design that here & now.

I so agree with you Vintagerepairer,

But I must say, I do prefer the foot pedals on the previous generation Ball machines. I have tried the DC40, DC50 and DC41 without the foot pedal release. It just didn't feel right and the machine would 'release' when I didn't want it to. I like to wheel my machine from room to room sometimes.

I liked the way the previous cleaners had a proper spring-loaded ball-latch system to lock the cleaner head in place, but I agree that the new ball cleaners do seem somewhat primitive and cheap as one pushes the head down.
