the real question is why are you vacuuming your keyboard

no harm in ways of static, like it wont kill it, and its dirt, dust, fuzz and chips and who knows what else is in there easily comes off with a vacuum 

easier then taking off all the keys and cleaning it that way, first cleaning it got in the year I had it lol. but truthfully I was vacuuming up all the ladybugs in my room and then i vacuumed my mouse mat becase it was super dusty, then I saw my keyboard sitting there waiting for its turn.

I take off all the keys and blow pressurized air until it's clear of debris, then individually wash each keycap.  Haven't lost one yet

I would not have the time to do that lol then putting them all back on the right way

is it really that bad to do? like is it frowned upon? i know it wont cause damage to the board in it

Vacuums are hard to control, when it comes to sucking things up.  You now have firsthand experience with that.

lol well i guess. i just didnt press my key down all the way from the last time i took them all off (why i wont do it again becase it was a mess)

Now imagine if someone has less than acceptable cable management.  

You could always order some different caps or maybe reuse caps from another mech keyboard if you have one, that way they'll at least all match instead of having a random W

coarser and their big font doesn't match any i have lol 

it's just arrows though, those don't really have a font.  What else do you have?  Obviously the stem type has to match

i have a razer black widow

That uses cherry-style stems, and I'd assume your corsair does too, it should work

or should i change all the arrow keys to WASD

I suppose that's another option but that would look a little strange imo
