Every day there was less and less until it was completely clean and little to no dirt. No matter how clean the pool floor looks you can put this in and it will always pick some dirt up. The people that built our house and who live down the street and also own a pool bought the same Dolphin vacuum and said the same thing, that for years they had issue with dirt or grit on the bottom of their pools and this thing got rid of all that. This is 21 years of them owning pools, that's saying something.
