Maybe it's not set up properly? I had the same issue with it, but a friend of mine that knows more than me in this helped me to figure it out. I also had to do a lot of cleaning manually, but after he set it up properly, I don't have to do that anymore. I'm not an expert but when I was looking for a registry cleaner free, the ccleaner was rated as the most popular registry cleaners among users globally, so I got it. It works great for me, so try to set it up properly and you'll see results from the first time.
