Why oh Why did the Jandy Vac end up in the cemetery? 18 years and the best cleaner I have ever had.... NOW 2 years with a polaris.. and it went kerplunk...did not like it anyway. . Looking at the robotic and heard Dolphin was the best -- by who? -- people who sell Dolphins... Trying to decipher which Dolphin is which - is like looking at mattresses. Every company has their 'own' name and I have no idea which to buy... I see the motors going out in 3 years and replacement costs high... unless under warranty.. My pool is 7' deep to 3 1/2 'deep and is rectangle with some angles.. About 40' long and 15' wide... I want the sides and wide steps vacuumed . We get debris from the golf course and some landscaping leaves every day.. WHICH one should I get? Do I really need the remote or is it just a play gadget? Will the computer chip in the Dolphin handle the areas to vacuum successfully without the remote? I read where the Dolphin does not work in cold water.. Well our pool is running all year --- Texas----- and the water temp. does get below 60. Anyone have an issue with this? help..gotta make a decision..... grannie...
