After a ton of research I had decided to go with the Aquatic Bravo Fury. It's supposedly made by the same company and the Blue Diamond and Aquabots. I was told it's basically identical to the Blue Diamond. It looks just like a Blue Diamond. Here is a link to it http://www.aquadist.com/aquabot_fury.htm
I'm on my second one. They are both doing the same thing. I threw it into the pool as soon as I took the cover off. My pool was covered with algae. It will not go up the walls. It occasionally will go up some of the slanted areas of the pool but it never goes up the straight vertical. I've watched it and it seems to just bounce off the wall. It does the same thing when it tries to go up my steps. It doesn't even reach the seats that I have since they are up the edge on the deep end. It also will not go to the shallow end of my pool. It starts to go up the incline and then just makes a wide turn and back down to the deep end. I've noticed that if I put the power supply on the side of my pool it will go up to the shallow end but not very often. The first one I had was also turning off after short amounts of time so the company replaced it. The new one is staying on for the full 3 hours but still has the same problems with not going up walls and to the shallow end.
