I have wanted a robot since my pool was finished in June but wanted to give the Polaris a shot first. Now the booster pump is leaking and the tail of the cleaner gets caught in the underwater rocks in my pool so my husband has jumped onboard the robot bandwagon. I have been shopping around and I am disappointed because Maytronics makes it so dang hard to purchase their products and I wanted a Dolphin m5. Also, a 60 ft. cord is not long enough as we did not install an outlet close enough to the pool. Husband is not liking the idea of a cord running across the deck either. Anyone have suggestions for a robot of similar quality to the Dolphins but with a longer cord or cordless? Or does Maytronics have a longer cord option? Thanks in advance!
