Vacuum Cleaners Discussions

I'm looking for a decent commercial machine to be used in a commercial setting in a video arcade by 16 year old kids that are in a hurry to get off work. We've got a Royal all M1028 that they are in the process of destroying. So far we've fixed, a few times, the pot metal handle where it connects to the machine . They also don't care what is vacuumed up. Although we've taught them to steer clear of pennies and dimes, the occasional hard candy still makes it's presence known in the fan case.

Beings that the video arcade is loaded with electronics, we are having a hard time with dust collecting on the circuit boards inside the games. With frequent air handler filter changes, the dust is still collecting, so a commercial machine with a HEPA filter is what we're looking for. And durable, as I stated. A Bag-first machine would also of course probably be the best idea with wide tubes leading to it. Probably bags beings nobody would ever clean the filter. Anything else I'm forgetting....oh...durability = #1 and then of course something that doesn't stir up the dust.
