Direct air motor vs Clean air motors

I'm going to guess filtration brings it down, same thing for sanitaire.

While not exactly scientific i've managed to get my hands on some hot pink sand. I do have a fairly plushy rug in the basement where my collection sits. to see how they compare to each other i've been pouring some sand then spreading and grinding it in with my shoes.

The best performers were the direct and tandem air machines both the kirby g6 and the riccar radiance had all visible debris up in 2 passes (2 forward and 2 back)
The lindhaus Healthcare pro took 3
the Simplicity 7 needs a new belt as i heard some squealing but it took 4 this will be re-done when i get a new belt.
The miele S7 freshair takes about 4 but there's almost always a little patch left after 4 passes, i have tried both the deep pile and low pile settings.
Oreck XL-21 3 passes
Oreck XL Ultra 9-10 passes
 
That's interesting.And you could be right about filtration but some of the Riccar don't have a HEPA filter I think some just have that foam thing but still get a gold. Could there be some favouritism going on?

And I agree Nar some cleaners will def wear your carpet prematurely
 
Filteration is possible

I do notice a difference in my Riccar Supralite between the Cloth-Hepa, and Paper bag. The machine seems to "breath" easier with the Hepa. My non-scientific method for this is you can feel the bag with the machine running. The Hepa bag you can depress very easily as the air is readily escaping, whereas the paper bag is firmer more balloon like with air not exiting as easily. This slowing of the air flow will effect the pick up abilities.

Like I said earlier, I would like to see a spec chart and test page for the machines. What brushroll, if there were stiffeners, bag type etc.
 
I think CRI should adopt a similar method as the EU test. Ratings from A to G for Carpet performance, Filtration, Energy and Noise that would give a clearer picture
 
I wasn't saying there was. Would just be interesting to see how much the difference is between a direct air such as a Kirby and the best clean air machines.
 
I understand what Marcus was wanting to do

He is not setting out to prove "Who's the best" he is just wanting to see how much difference there is between the two cleaner types.

Turbomaster, I don't think anyone is trying to start a Mine's bigger than your's war, but if you need scientific proof, the below link is what we are referencing.

I think it's a well known fact that a direct air motor will produce more airflow at the floorhead than a clean air motor but that doesn't mean I'd prefer a Kirby to a good clean air motor like a Miele or Sebo because I wouldn't :-)

But if I wanted the deepest clean I would choose a Kirby or Riccar Radiance.
 
Don't count the tandem air machines out

Though my First love is Kirby, Then Royal, the Riccar/Simplicity machines are pretty dern awesome. Though they differ in their agitation where the Kirby/Royals will form a seal or as Kirby calls it "Triple Cushion Vibration" pulling the dirt from the bottom, the Taconey Twins use three brush strips and beat the heck out of the carpet with good suction and airflow as well.

Marcus, If you can get your hands on a Kirby with a Dirtmeter, I can describe a very accurate vacuum test that you can use to test any vacuum against a Kirby or test any other 2 vacuums against each other, and you can do it at home.
 
So Stan and Kirbysthebest have used EVERY vacuum in the world EVER thus they know....... or they have read some report somewhere that shows this and proves it?

Until you have then one simply cannot say. Just like I cant say as Ive not sued EVERY vacuum made EVER.
