My choice is between a robotic Blue Diamond or a Pool Blaster Max. When a full, lengthy cleaning and brushing is required, I use the Blue Diamond. But for the daily detritus that accumulates I use the Pool Blaster. I am of the opinion that it is a terrific tool, requiring far less setup that a skimmer vac, does as good, if not better a job and you can either stick it on a pole or give it to a kid to have fun diving and sweeping...or do it yourself!
