You're not going to be able to avoid her pooping and peeing all over it. Most hedgehogs do, they poop and pee on the run in the wild, so on a wheel, they think they're leaving it behind when they're really not. They absolutely need a wheel for exercise, so you're not gonna get out of having to clean it. The best you can do is order a Cake Walk Supreme from Reaper, they're supposed to be extremely easy to clean. I just got mine today, so have yet to try cleaning it.
