After some pretty heavy research on this, the best site in the world, I decided to get the Blue Diamond. I ordered the non-remote control model as it was much cheaper and because I read a number of people saying they didn't really need it after all. I concluded that if you are going to drop it in and spot clean with the remote then you are counted as having used a cycle. Why not just drop it and leave it for the full hour and get your cycles worth? I do see it could be useful if your robot constantly misses some spots but that issue would be a major pain on its own. Also, the non-remote model is lighter and has less components that could break.
I chose the BD for these primary reasons:
1 hour cycle time to clean the whole pool. It isn't one of my kids and I just don't want to see it in there all the time.
2 micron filter
Great warranty - 4 years/400 cycles
The PVA rollers contact the entire surface
Rollers are cheap enough to replace after some years of use
Caddy included (it is crazy that a robot wouldn't have one included)
Sure I would rather have a top removing cartridge filter. Maybe a sleeker design like the Polaris 9300. But when you look at the specs it is hard to beat.
My tracking number says it will be here tomorrow. I'm super excited and might even dump some stuff in the pool just to see how it does!
I'll let you know what we name it.
