Attachment for wet-dry shop vac for cleaning pool?

Hi;
We have a 'splash' pool (about 6ft dia). Unfortunately, the drain for the pool is on the side, and not the bottom, so it is impossible to get all the water out through the drain.
I am able to get more water out by starting a siphon, but that still leaves puddles of water in the pool.


Using a wet-dry shop vac with the standard floor wand is tricky. Unless the wand is turned slightly on its side to allow some air to get into it, the pool liner will get sucked up. I am afraid that this could eventually tear the liner.


What I am looking for is a wand with a flat bottom, but with spacers to keep it from actually touching the liner.
A long time ago, I had a pump with something called a 'puddle gulper', which attached to a garden hose (that pump had standard hose fittings). It was flat, with small holes to prevent anything large getting into the pump. It also had spacers to keep the flat bottom slightly above the floor.


Is there any such animal for a shop vac?
I have two shop vacs; one large and one small, two different sizes of hose. I'm not too concerned about the diameter of the attachment's fitting, as I could build an adapter from plumbing fittings.


Thanks for your help
