Maybe because it was slate it was diffucult to clean? We use ceramic tile and have no problems. Whenever our beardie goes to the bathroom we just wipe it up with a papertowel. In my opinion ceramic is the easiest to clean, and looks the nicest.
What kind of uvb are you using? If its that fluorescent the uvb will not be reaching yours beardie because it is too far way.
