Query: Save your money and this piece of junk!!!!

After having this piece of junk for 2 months it broke. I contacted littermade and there is no option for a refund or a return. Even when this worked, it was a hassle and did not clean the box, and the unit smelled! Stick with a regular box, I had to clean this box more then the regular box!
