@kirby519 I'm not trying to be rude dude. But you're way out of touch with reality here.
Dirty air/direct air machines, fell out of favor for not having attachments, lack of power and having extra maintenance that was no longer necessary.
Dude I like Kirby vacuums they're just not the end-all to the industry not even close.
You start arguing from a place of authority, by saying you're whatever age.
Then you go on to say something about "co-workers or boss following me on vacuumland". I'm very confused by the statement all together.
Here's an FAQ video bring you back to reality a little bit. Maybe know who you're talking to?

We don't need to turn this into another thread about bills hillbilly science
That's been discussed enough.
You need both air flow and sealed vacuum numbers for a machine to clean well.
The working vacuum in the machine is very low as a result.
Numbers don't lie if you test all the numbers and not just masturbate to CFM.
Also what bill doesn't understand and refuses to talk about are air flow paths. The shape of the Kirby nozzle& fan chamber is rather inefficient . The nozzle especially creates unnecessary turbulence with a brush spinning inside it.
Again I'm not saying the Kirby doesn't clean I'm saying it's below average for what's available in 2020.
