Electrical appliances in general are usually very alarming to cats. Mine have always been terrified of the hoover, hairdryer, of course drilling, banging etc. even the noise of a spray or a can opening!
I'd imagine it to be unnecessary and scary for them. It would make them hand shy and scared of the normal brush. Mine would anyway.
So no, I wouldn't and probably physically couldn't.
My big boy scratched the living crap out of my stomach and nearly took my finger off last time I tried to put flea treatment on him!
