Last year after reading many great reviews on the Dolphin, I bit the bullet and bought one. To be honest, it is the worst money that I have spent on pool equipment.
Mine will run over the drains without getting stuck, but the drains are just high enough that it throws off the pattern that the Dolphin is running. So, it will stay in the deep end all day unless I stay with it and move it around by the cord.
My pool has radius corners, which really causes problems for the Dolphin.
Knowing what I know now, I'd have kept my money and stuck to vaccuuming the old fashion way. I can vac in 45 minutes, I'll spend 2 hours guiding the stupid Dolphin around the pool.
