Best pool cleaner ever

It is the best poop cleaner because all you have to do is put it in the water and out and press go.

Love this cleaner

This is my second year with this cleaner. After struggling with Polaris for many years I am so pleased with the Dolphin. Easy to clean. Cleans well. Only became entangled with cord once. The cord does twist on itself but I simply untwist it every time I empty it. Highly recommend it over the Polaris. Seemed I was always working on the Polaris.
