I have a Tiger Shark Pool cleaner that has one problem. The impeller doesn't turn on its own. When I plug it in and turn it on, it travels around the pool like everything is great, but without the impeller turning, the water is not being pulled through the filters, so it is not doing its cleaning job. I don't really need this cleaner because I bought a Polaris and booster pump that works for our pool. I don't want to just throw this Tiger Shark away because I know it can be fixed, and the other working parts are very expensive, so I know someone could use this for parts if they have a Tiger Shark. If anyone has any suggestions, please let me know.
