VACUUM CORDS

I hate vacuum cords. I don't mind vacuuming. In fact, I would probably ENJOY it if I didn't have to keep untangling and moving and kicking the fucking cord out of the way. And how many times have I RUN OVER the cord, stripping it, causing that nasty "burn" smell to permeate the hallways, exposing the wire so the next time I grab it while the vacuum is on I get ZAPPED. I HATE THAT.
I want someone to invent a vacuum (with at least 12 amps) that remains charged for an hour WITHOUT A CORD.

I mean, COME ON VACUUM MAKERS!  We can send people to THE MOON but we can't make a vacuum without a cord? 

And I'm not talking about those little hand-held shit ones that only last five seconds before you have to charge it again.

I'm talking about a KICK-ASS, MAJOR SUCTION type of vacuum... WITHOUT A CORD.
