is a 12mt robot like the Dolphin 2001 able to clean a 13x6 mt pool?

I am pretty sure he means meter's. If you look at robot spec's on maytronics website it show recommended for pools up to 12 meters on many models. The cord is 59 feet long. You need to look at where the power supply will be. If it's away from one end you may have a problem. If the power pack was placed near the middle you would most likely have 20 feet of cord that never gets used.
