Welcome to TFP! If you haven't found it already, there are LOTS of posts on TFP about automated cleaners, so put our search feature to good use. I would let some of our fellow TFP'ers chime-in about the UV combo. I'm no expert on those, but some of our forum members may have personal experience with that product and will give you an honest review. And as Casey mentioned above, make sure you order that TF-100 test kit before you fill with new water. Enjoy your time with TFP!
