You can vacuum a salt water pool the same way you would a non salt water pool. If you are vacuuming on the filter setting, your filter will help to clean the debris out of the pool. If you are dealing with a very dirty pool and use the waste setting, you will be wasting some of the water from the pool in the process. Depending on how much water you take out and need to refill, you will most likely need to add some salt back in to get your salt level back to normal operating levels.
