End of Dyson Cinetic?

[sebo4me]

I've heard rumours that Dyson are going to phase out their Cinetic models as they have come to the conclusion that it's a failed system. It lets to much fine dust through to the motor causing premature motor failure.

Has anyone else heard this rumour?

I have not heard this rumor. I expect that it's likely though. Since vacuums were first invented, engineers have tried, repeatedly and without success, to make a portable vacuum that doesn't clog with dirt, doesn't loge airflow (suction), and cleans with 100% suction always.

It had been done with Central Vacuums since the 1913 cyclonic Spencer Turbine was launched, but that's not a portable vacuum.

Rexair tried, the Series A had no water and only cyclonic action aided by a rotating separator. It let too much fine dust through, clogging the exhaust filter. Water was added, the exhaust filter was eliminated, but it still didn't trap all the dirt. Dust triumphantly escaped. When asked about this, then President of Rexair was reported to say "It's clean dirt...it's been through the water".

Electrolux would realize they could never have the ideal, so they made their cleaners Automatic. The user could select who 'clogged' they wanted the bag to get, and the machine shut off at that moment. But that's not the ideal.

Dyson tried. He really did. His problem is the varying amount of air that goes INTO the machine as someone cleans. Imagine the air flow when using attachments like the crevice tool. Use that crevice tool to pick up fine dust (as people do), and the separation efficiency of ALL the cyclones is reduced dramatically.

Cinetic was a good idea, an 'ideal' that doesn't and cannot ever work with 100% efficiency. Not in the average home. Maybe in a testing lab, but not in the home.

It seems there is no other way for a vacuum to have 100% efficiency with regards to airflow and dirt separation, other than the design of the 1913 Spencer, which today is the cyclonic Vacuflo.

So why does the Cyclonic Vacuflo work better than other cylonic vacuums?

Marketing BS

I especially love how they say "No dirty filters to clog." If you look into the left section of The Ball, you can find a post motor filter!

vacuflo and other cyclonic vacuums

I would not be surprised if they discontinue the cinetic vacuums, as Tom said, a nice idea, but there is a big difference between lab tests and actual useage. Regarding the cyclonic central vacuums, there are some major disadvantages to this approach. Even though these vacuums claim that there are no filters, there is a screen that must be cleaned on a regular basis, this screen is basically functioning as a filter. These vacuums also have more dust that goes through the motor and is then vented outside. Finally, as with other bagless vacuums, emptying these can be pretty nasty. No thanks, give me a bagged unit any day. I have several central vacuum units here, all use bags.

My Mom used to have a NuTone bagless central machine in one of her homes-I was the one that had to dump that nasty thing each year I came to visit her.Had to take a shower after the affair.Bagged machines for me ,too.Hate the thought of dumping many gallons of dirt and dust!And you need ANOTHER vacuum-bagged to vacuum the bagless machines filters.Most of the bagless centrals don't last as long ads the bagged versions-too much very fine dust and dirt gets into the motor-killing it.You have to be very up on cleaning-replacing filters.

Possible Reasons for the Cinectic Demise.....

In addition the the reasons Tom mentioned I can see why they might want to discontinue the Cinetics line:


1) They are probably getting costly for them to keep servicing, since the dust is getting into the motors and a lot of people are coming back for warranty work, probably more than their other lines.


2)They are more costly than the regular Ball series, with less suction. They are also heavier than the Ball series too. With this I believe that they are not the big sellers that Dyson believed they would be, which is why they saw fit to update the Ball and not the Cinetic line. I also know there are a ton of these refurbished, and they tend to go for cheap relative to their high MSRP new.

The upright model has been consistently and quite heavily discounted here in the U.K. lately. I've seen it at £250 in my local Euronics store which is half price. Maybe a further sign they are being discontinued.

I was worried about the lack of a pre motor filter on this model. It reminds me of Fantom machines. A simple pre motor filter solves fine dust issues and its easy to wash so why not have one? I guess they just wanted people to get excited about the "No Filter to Wash" Idea. Even the Original Cyclon/G Force claimed to have no filters to wash or replace. Their motors must have suffered much like the Fantom machines.
