My airflow tests (mainly from the nozzle)

[mike811]

In this thread I share almost all of my airflow tests what I have done.
My main focus is the nozzle airflow, but some pictures have airflow measured from other places and also suction figures.

First one is all of my current canisters.
I used Sebo ET1 ph in all of these tests.
Power usage is only what the label says.

Now something totally different.
My DIY upright with Shark (750w) motor, Dyson DC14 bin and Electrolux PH.
Let the video speak for itself.

Haha here we go again

I'd still like to see how the Kirby does with fine powder compared to your Felix, Vorwerk and Cylinder cleaners. If the Kirby does much better I will never mention it again

 

[mike811]

Here is a fun fact.
35 years old Miele S234i has 98 hose cfm and
few years old Miele C3 has 109 hose cfm.
So basically C3 is more efficient using 600 watts
less power but only losing 11 cfm to the C3.

That Vorwerk Is Really Something Quite Special

But I have a question: Does the G6 label really say 580 Watts? I've never touched a European 240 Volt Kirby and I'm surprised that it would be rated at less than 840 Watts. I would expect the motor coils to be different but I wouldn't expect the total power usage to be that much less. Have you had a chance to measure the actual power usage of your G6?

Yes the label really says 580 w and 635 w in the hose mode.
However for some reason many of my vacuums use much more than the label says.
For example Vorwerk claims 900 w, but it uses around 1200 w.
Same with some older canisters: Claim 1000 w and real usage over 1200 w.
I need to find my power measuring unit to test the Kirby power usage. I have it, but right now I can't find it.

wow! You certainly made

clear and concise listings there. Impressive!

Thanks! I have been done these a lot.
These give the raw numbers how the different vacuums perform.
