Vacuum Cleaners Discussions

How sealed are Dysons? And how good is their filtration? I know the uprights - at least the older, older ones like the DC07 and such might have potential problems with sealing, such as show in this video right here: http://www.youtube.com/watch?v=mXA0N0V2uOQ However there could simply be something wrong w/ that one, who knows. BUT ANYWAYS, are the NEWER uprights COMPLETELY sealed? What about their canisters, such as the DC22, 23? Like does any air blow out of the cord reel or such, or ONLY out of the exhaust where it's SUPPOSED to come out from?

Hi Severus:

Good link to allergy buyers web site.  If I recall, you posted this site before here.  And I was impressed tho may not have mentioned at the time.  Looks like MIELE and SEBO vacuums get the highest andmost number of excellent ratings, even the newest MIELE S7 upright series, even if not all their [MIELE/SEBO] models are actually HEPA rated and/or sealed vacuum systems.  Thanks for posting.

I agree with you that the allergy sites tend to be good sources of information for allergy sufferers.    They should get a lot of feedback from their customers about what works and what doesn't.   However, they don't seem to be nearly as rigorous as CR in their testing.

I would agree that people with serious medical conditions should stick with a bagged vacuum or even a central vacuum.

Miele's superior filtration does come at a price.   I'm not sure, but Riccar and Simplicity may have filtration comparable to Miele.  You could always visit the Tacony vacuum museum in St. James, MO and get one at the factory store.

The full size RICCAR/SIMPLICITY uprights and canisters boast in writing that they are 100% sealed systems with HEPA S-Class ratings.  Interestingly, CR rates the bagged RICCAR Brilliance [succesor to Radiance] and SIMPLICITY Synchrony Premium uprights very good for emissions rather than excellent, as one might expect with 100% sealed HEPA S-class.

Hi,

Is there a comprehensive guide as to acceptable to harmful levels of vacuum filtration? How many microns retained actually  constitute excellent, very good and good filtering service? CR's excellent to very good rating slots would cause me as a consumer to think there's little difference.  What does a micron or  two missed in the filtration process really mean to a serious dust allergy sufferer as opposed to machines that obviously don't contain dust well?

Hey yo DIB, this ones for you man: http://www.vacuumland.org/TD/THREADS/MODERN/7903.htm?36 If you haven't discovered this sight (vacuumland) and the awesome dude that is "vintagehoover", then you're in for a treat. Vintagehoover is THE dude to talk to about Dysons, and has more Dysons than some people seem to have brain cells. Awesome stuff. I, like yourself, really like Dysons, and I appreciate your passion for them man, as I share that, as well B) (though you might like Dysons abit more than I do ;) ) Anyways, enjoy.

Hello Venson:

Vacuum emissions testing by CR has evolved over recent years.  In the late 90's CR's testing for emissions involved measuring the particle concentration in the air of a specially prepared room before and after vacuuming up wood flour from a medium-pile carpet.  CR was quick back then to note when and in which cases vacuums w/o HEPA ratings matched/bested emissions with models claiming HEPA.  More recently, CR measures the release of small particles from the vacuum during operation.  Not sure why CR made the emissions testing changes.  Current CR emission ratings seem to indicate parity among all brands and models with the vast majority of ratings ranging in very good and excellent, as you say.  10 years ago, CR vacuum emissions ran the gamut from poor to excellent with an average overall rating of good.   Not sure if vacuum emissions drastically improved during this time and/or the CR changes are making emissions distinctions harder to measure.  More likely both factors are working in concert.

OK I'll admit I only scanned this thread but I don't know of 1 bagless system that is a sealed system. Can you even make a bagless into a sealed system. It would take a ton of screws and much better seals that's for sure.

Tell me Einstein,

If a hole is drilled in the side of a Dyson clear bin or through the drop away lid, does it blow (exhaust dust into a room) or does it suck (dust into the vacuum)?

I say you’re full of$hit and a con.

The so-called dust you observe around the lid is residual dust after a bins contents are emptied and not wiped away.  When a Dyson is turned on the drop away door pulls inwardly (towards the suction motor) and any layperson reading this can observe this for his/herself.  The only leaking is me posting (leaking) how the con is done.

Could you name your money making brands here and on this public forum...    I'd like to rip them and their price points apart.

No Dubber, Procare is right,after 4 months the spine behind the dust bin is filthy due to the seals ,but so wasnt a REGINA brooms except they only costed 20 bucks

While I got the bulk of the dirt out of the pet smelly DC07 cyclones, I could not get all out [year 3 of a 5 year warranty].  Just doesn't lend itself to allow for a total cleaning.  Worse designed bagless in the industry because the cyclones can't be thoroughly cleaned of its dust and dirt.  No doubt the reason it is discontinued and the filter cleaning maintenance schedules reduced in half on all future dyson models.

PS:  Is it still the case that a new cyclone assembly in the DC07 and DC14 runs about $100?
