Dolphin pool cleaner Comparison summary

In our opinion all of our chosen 5 best Dolphin pool cleaners each had features that will best suit a pool owners own unique needs. Whether it be the fact that they’re on a budget and need a more affordable option, or the fact that that their pool is prone to multiple types of debris and they need a more versatile and powerful cleaner.

However, if money was no issue then we would have to go for the Dolphin Sigma. We feel like it is the best pool cleaner in terms of features and cleaning ability.

If we were shopping on a budget then we would have to go with the Dolphin Nautilus Cc Plus. It packs many of the same features that many of the more expensive pool cleaner had, however its main downfall was the fact that it wasn’t able to clean to the waterline.
