Does anyone have any suggestions on a pool cleaner that I could use that would clean my pool that has a bumpy liner. I have to get in the pool to clean it because of all of the bumps. It is difficult on me because I have neck issues. We had the worst pool people ever to install the pool. We did not know about the bottom until after we had paid the people and it was warm enough to get in. Are there any automatic cleaners or vacuums that would help me?
