Well I just want to add myself to the list of happy owners of the 2007 Blue Pearl.

I was pretty skeptic at first as too how much of the pool could actually be cleaned in the preset three hours. In fact I had planned on running it twice for the first cleaning (I hadn't vacuumed my pool for two weeks in preparation for this), but it accomplished all of this in the first cycle. Color me impressed! The only thing left over was some algae growth on the walls that needed to be brushed off, on the whole the unit worked perfectly. I have a very complex bean shaped pool, and while it didn't climb the steps, I watched it cross over from the shallow to the deep end many times.

I'm not sure what the sensor package in this machine is, but I know it at least has a tilt sensor...When it turns, it tilts up to avoid too much traction, and it if passes a certain angle, it will stop the turning process and begin filtering again. It also has a way to know if it has hit the waterline, as soon as it starts sucking air it will back down again.

And if you guys are deciding on if you need the buggy or not, spring for it! Maybe it was a shipping mistake, but we got the Blue Diamond cart (even says it right on there) instead of the pictured one, and it’s much better than putting the BP on the ground. Only thing is I wish they made it easier to get the spool of wire off the two hooks by swiveling or something equivalent.

I've only done one clean so far so I'll report back after a few weeks have passed, but initial indications are good!
