Then get a Sho[-Vac. Those things are very simple, and look like they are
mostly made of off-the shelf parts. I don't know, but the hose looks like
something off the shelf, and the pieces that fit in it do too, all made of
plastic. So one might be able to find replacement parts (except the
company seems capable of offering those themselves) in the plumbing
department.
THe bonus is that it can be used to clean up liquid too, so all those beer
spills can be handled.
