I think we had one of the more successful vaccuums last year. We had 2 FP's turning 2 stacked shop vac impellers (the output of one feeding the input of the other). I know how that system compared to our regular shop vac at 120 volts so I tried our shop vac with the same cup we used last year on this years donuts because, like you, I thought it would be the simple solution and hey 2 years in a row would be cool. BUUUTTTT the suck was enough to hold the donut in the vertical but any little bump on the off side resulted in seperation.
If you get it to hold better thanb that I'd love to see how ya did it!!!!.
Good luck
