I had a problem where the grey ring would end up shifting around, which would cause the rake to catch on various things. I ended up using some clear plastic packing tape and taping the grey ring to the main body of the litter box at 4 places around the outside. (One of them I had to remove the collection box before I added the tape). It seemed to fix all the catching problems I had.

I would try to leave the vertical wires in place since I don't know how well it will deal with clumps that are stuck to the side of the bowl without it.
Good luck.
