Does anyone else vacuum air?

Does anyone else vacuum the air?  

I was doing a little vacuuming this morning and I face the south so the sun is nicely shining into my living room.  I've been limited as to how much I can lift or push since being discharged from the hospital, so it's been a few weeks since I vacuumed.   With 3 cats, the dust and cat hair adds up.    As I'm vacuuming, I'm seeing all kinds of dust and small cat hairs being thrown up into the air, so I used the vacuum wand to vacuum the air to collect it all so it wouldn't land back on the floor or furniture.  Then I realized something!   I do this every time I vacuum!  LOL  Then I found myself thinking of a way to turn my Dyson into a dual suction, so that while I'm vacuuming, the vacuum can be sucking in the air around it, (instead of blowing it out), and vacuum in the dust etc that is in the immediate area.

Anyone else OCD about dust that they actually vacuum the air?   

I've done that! It's kind of horrifying to see all that dust and hair in those sunbeams!  I'm always amazed at the cat hair the sunlight shows on everything, I didn't see it in the evening! That's one thing I've always said was bad about cat hair, it "floats", much more then coarser dog hair.
