DC25:

Nice review, thanks.  How much is the DC25?

DC18,

I somehow got it in my head early on, that the DC25 performance was par with all Dyson full sized uprights.  I was wrong, sorry.       

 

James wants his potential consumers to judge suction strength on “Airwatts (Suction Power)” and so it seems the DC25 is the better choice in terms of handle weight, overall weight and maneuverability compared to the DC15 but the downside is more pre-filter washing.  I’ve read almost all James’ cyclone patents and did some testing and observing on my own, there are a lot of variables that go into making a good or “perfect” cyclonic vacuum cleaner.  Many things I discovered are not mentioned in his patents.  James only used enough verbiage in his patent claims only so to get his physical invention patented but not unnecessarily give away the trade secrets to HIS cyclonic’s.  Certainly the DC22/23 look to be the “perfect” or near perfect cyclonic filtering vacuum cleaner.        DIB

Carmine,

The DC25 is $499.99 while the DC24 is $399.99.

Thank you, DC25.

But you knew that already didn't you Carmine ;-)

So that means Dyson has changed the valve design for the 3rd time.  The first Dyson DC01 and DC03 used to have no suction until the wand was unclipped from the main body but the valve had already transferred the suction to the wand but there was a seal preventing any suction which meant handly any anirflow going to the motor so the motor pitch would rise quite a but (My old DC03 was VERY noisy with its tiny 700 watt motor).

Dyson then went to the DC04, 07 and 14, 15, 18 etc etc with havig full suction at the wand with just a Cap covering this which I felt created extra noise also.

The addition with this new valve design in the DC24 and 25 - Suction at the head until the wand is unclipped is a welcome addition,  I suspect its to help keep the machine quiet and is safer than having full suction at the wand when upright or the extra strain on motor as on the first models.

Dyson seems to be getting better with reliability which were big issues in UK with the first generation models.

No Ace, I didn't.  If it was mentioned already, I missed it.  The last I looked at the dyson site, it wasn't there.  And I didn't see it on the comparative dyson uprights' post.  So I asked.

I looked at the dyson site and see the prices.  Also appears that the "ball" technology is dyson's signature upright IMHO.  They get top billing and exposure.

Hi DC25

Nice write up on the DC25 model by the way.  I forgot to mention about the filter in the ball housing!  So you where impressed by this model.  Now that I have test driven the DC25 I have to say I prefer it over my DC15!

DC18

Hi DIB

Thats ok.  I have to say the DC25 is very impressive and it a very welcome leap forward from the DC15.  Yes the filter washing is a downside but the performance is a leap forward from previous models.  As for the filter washing I don't always wash mine every 6 months, i can go longer and the filter is not that dirty.  I think it depends on what your using the vac for and the area you live in.  So the 3 months on the DC25 I could probably get away with 6 months!!

The manufacturer's instructions for maintenance are generally based on average usage.  For vacuums, I suspect that's 2 times a week.  I would be very reluctant to make a general statement about circumventing the manual's guidance for the purpose of convenience especially from 4 times to 2 times in a 12 month period.  Why?  Sometimes you vacuum more than 2 times per week.  Or vacuum longer periods of time.  Eyeballing a filter to determine if it is clean/dirty is a very primitive means of knowing if it is.  Why? By the time the dust and dirt accumulates on the filter surface for the eye to see, the filters' pores are already saturated and degraded.  Heat from the motor's operation degrades the filter material/operation also.  Failing to perform the filter maintenance as recommended by the user guide, causes the motor to run hotter than usual.  Hotter running causes premature motor failure.
