Query: DOESN'T DO IT'S JOB

I AM NOT SATISFIED WITHTHE PRODUCT. THE LITTER BOX DOES NOT CLEAN COMPLETELY, IT SCRAPS THE TOP OF THE LITTER BUT NOT THE BOTTOM OF THE BOX. WHEN I RECEIVED THE PRODUCT I DID NOT RECEIVE THE ADAPTER FOR THE BOX. I E-MAILED BACK WITH NO RESPONSE. I HAVE HAD OTHER LITTER BOXES WHICH HAVE PERFORMED MUCH BETTER.
