First let me start off by saying I have owned and tried , the Polaris 380, Polaris 360,Polaris 340, Baracuda G3, Letro Legend, Letro Platnium Truck, Aquabot plus wireless remote, all these were bought and then returned or sold on Ebay .I now have a Blue Diamond remote AND a Hayward Phantom.I drive over 6 hours for work each day and WILL NOT vacuum my pool after a whole day of work, so I own the 2 best pool cleaners (in my humble opinion)If you want a pressure cleaner go with the Phantom , if you're looking for robotic go with a Blue diamond .I am on my third season with the Blue Diamond , I got it at Frontgate for $1100 brand new , I saw it on their website, wanted to get it but the $1600 price tag was a little too much for me , one day I go on the website and one of their geniuses swapped the prices of the remote model to $1100 and the regular model to $1600 !!!! I jumped for joy, placed my order , and sure enough they shipped it out and charged me $1100, couple of days later they realized their mistake and swapped the prices back to their correct amounts.My boss, who uses my pool decide this year to give me a pool present , he gets me a Dolphin Dynamic remote , I figured what the hell, let me try it , if it's good I'll sell the Blue Diamond on Ebay , probably get my $1100 for it as they are going now for $1600 new and I also gain a 3 year warranty on the Dolphin , i throw in the Dynamic and it's a total waste of time, !! goes back and forth over the same line for 2 hours ! I call customer service , they tell me to set the cleaning time to 8 hours as my pool is 25 x 40 .tried that and then it went over the same line for 8 hours !!I sold it on Ebay, and kept the cash .The Blue pearl is a less expensive model but I'm sure it's fine, you can order them from Frontgate and they have (just double check for yourself before you buy) a 90 day money back guarantee, use it for the summer and see if you like it .The Dolphin's were the original robotic pool cleaner , looks like their American rep for them, copied the cleaner and opened Aquabot, Watertech which makes the Blue Diamond is the son of the owner of Aquabot . in fact the Blue Diamond warranty registration card goes to Aquabot service department !!
