Vacuum Cleaners Discussions

1)  Nov 21, 2007 James Dyson t.v. commercial parodied on Saturday Night Live.

2)  March 17, 2009:  While many independent vacuum dealers bad-mouth, lie of and/or dismiss James Dyson and his teams contributions, many others champion the man.  Watch James Dyson in his element - in his Malmesbury Headquarters.  NBC’s “Today Show”  http://video.msn.com/video.aspx?mkt=en-us&vid=71fa9222-10d2-413c-bf31-0007895697ac

2)  Older video news:  I could not resist...  A Hottie car-news chick mentions the rumor of Dyson working with car makers, and Oreck gets a mention too (funny).

Hi DIB,

Even if he did loosen the cover the air he is measuring is not leaking out, it would be getting sucked in.  The air being measured would be exhaust air  from the hepa filter, mixed with unfiltered air and resulting in the high particle count.  If the measurement is taken at the filter, similar to how the Miele is done the count would be dramatically lower. If, as Jerry says, the air is leaking from this seal...would it not be drawing the Kapok in rather than blowing it away?

Hi Carmine,

My issue with his Oreck video is where he places the particle counter. Doing a particle test at the rear vent and neck on the Oreck would be akin to doing the same thing at the neck of a Miele powerhead.  There is no way that will give a zero reading either.  Does it make the Miele a bad machine?  No, but it doesn't make the Oreck a bad machine either.

Hi Dusty,

Thanks for injecting common sense.

Q:  How in the heck does the intake side blow (kapok)?
A:  It doesn’t.

After I downloaded the video and played it frame by frame, here is how the con works...
1)  He tampers with and/or breaks the pre-motor seal/s.  He then places Kapoc a little above the pre-motor compartment attempting to show a leak, but instead (in 3 to 5 frames) the Kapoc is sucked towards the intake [sucking] air-leak.  He quickly...
2)  Lifts the Kapoc up and into the exhaust air-stream and releases.  That's it.

The illusion (if it can be called that) is due to the camera angle (it's a little difficult to get a depth of view).

No science here, just snake oil.

Hi Dusty:

You're right and I can't/don't disagree with you.  The issue with all comparative particle counter readings in vacuums is where to locate the nozzle for the test readings and consistency for comparison.  The best tests are done for canns, where the particle counter meter can be placed in the same location [filtered exhaust air] for comparison testing.  Even with this, you'd have to ensure both have/don't have HEPA bags and HEPA filters for equality. 

WRT ORECK, Gerry Rubin takes a reading on the unfilterered motor exhaust.  Not consistent with the MIELE meter test [filtered exhaust air].  Best place to obtain a poor air quality reading in the ORECK and best place to obtain a perfect reading for the MIELE.  But in all due respect to Gerry's demo and MIELE's air quality, choose any MIELE location for the meter reading.  You're bound to get an impressive reading.  Conversely, choose any place you want for any upright reading, and you're bound not to get a good meter reading.  A con[spiracy]?  No, the results achieved are accurate.  It's just the nature of the biz.

Hello Everyone,

Open fan uprights, by their design, have to have a cooling fan which is going to expell particles from the carbon brushes as they are worn away. A power nozzle has a cooling fan, too, right, albeit a tiny one? So a particle counter held at the vent slits of a running power nozzle should yield a high count as well, shouldn't it? I have not looked for the vent slits on a Miele power nozzle, but how else could the motor be kept from overheating? And if the Miele power nozzle has vent slits, then a particle counter placed there would yield a significantly higher count than just room air, right?

And on the subject of the particle counter, Jerry always takes a count of the room air. The counter does not care if the air is stagnant or tornadic, but the faster particle laden air moves past the sensor, the more particles it is going to count. Also, Jerry always tests new Mieles against used machines of whatever brand. While the particle count may be quite low on a 20yr old Miele subjected to proper maintenance, will it be absolute zero? Dunno, and until someone does precisely that and posts the results, we won't know. And isn't interesting that Jerry has not posted a video of the Miele going up against a Lindhaus, Sebo, Emer, or Bosch? But then he only wants you to consider machines he knows he can prove to be inferior to the Miele.

The Dyson vid? The emptying of the container, and and explanation of the expense of having a belt/clutch assembly replaced should have been sufficient. But IF he was going to tamper with the outcome, as least he should have reshot the vid so it wasn't detectable.

Hey Dude, listen to over 35 years worth of experience in the business.Who are we to tell the customer how much to spend,whats good ,whats junk, hepa this filtrete that,on board tools here ,crush proof hose here wire reinforced smooth bore there,

Do you want to know what draws the most attention in our stores, A 1942 XXX electrolux, And a filter queen from 1978, Ones has a shake out cloth bag, the other uses a conical filter cone B.T.W the filter queen will suck a new riccar, miele,bosch, or any state of the art machine inside of it.And it real quiet also,

B.T.W. Venson, im starting back up my Kirby collection again,just for kicks, should see the look on customers faces when i have 20 plus kirbys on the floor in an aerus branch...........

Hi Trebor:

Gerry Rubin has a likeable sales charm despite his misguided antics.  I suspect that most non-vacuum professionals  would come away from the demo with this point:  The kapoc quickly rendered a DC07 inoperable by hitting the max full line so soon.   Requiring the user to pause and do a dirt bin dump before proceeding.  While the MIELE cann in contrast picked up everything in dyson's dirt bin [the largest dirt bin capacity of all dyson models] and still had a long ways to go before needing a new bag.   All the rest is an entertaining side show for effect.  Very appropo for Gerry Rubin.

Hiya MOLE,

Filter Queen has been tops in my books for many years. I know and understand all the arguments in regard to straight suction versus an active brush roll but FQ is one of the few straight suction cans I'd want around to attack someplace in need of a real cleaning with. I hear the the new models with the improved powerheads are pretty good on carpeting. However, I think this brand too is going to suffer some in future due to price.

Speaking of Electrolux, I just saw one from 1939 on eBay -- the single vent version with the spring behind it not the inward swing "saloon doors." People also need to see the Lux XXX to get at least an idea of what a well made machine looks like. Then again, maybe they shouldn't. A long time time will pass before we see that calibre of work again.

The XXX usually sold for around $75.00 -- right? Considering that during its time $75.00 a week would have been considered a highly adequate salary, I'd think people with an income near that range were getting a real bargain as it turned out that these Luxes are still around and working AND still repairable.

By the way, what is Aerus doing these days?

Best,

Venson

Exactly the reason we don't use a particle counter (though we do have one) for use during a demo.  Finding the sweet spot where you can get close enough to a filter without surrounding air being drawn in is not an easy task on most machines.  While I've been able to achieve 0 counts on some Riccar and Eureka product, the filter grills usually get in the way of producing a true reading. Sebo, with it's soft bumper exhaust is a whole other story.

Trebor:  Jerrys done Sebo too, just not a vid.  You can see his review here. http://consumer-reporter.blogspot.com/2008/04/miele-versus-sebo.html
