are dyson vacuums from dyson spheres
@RikerGoogling Only while they're being built?
@RikerGoogling I was 30 before it hit me that Dirt Devil is named that because of dust devils.
@RikerGoogling They are the larval stage of dyson spheres, that's why they collect matter
@RikerGoogling It's part of their construction.

@RikerGoogling
Well, yes, actually.

You see, after you've built the Dyson sphere, you need a way to put the star inside, which could be your star or (if your Dyson vacuum is strong enough) somebody else's.

Just be careful while emptying the dust collector.

@RikerGoogling If you drain the air out.
