Pros: Helps with leafs not going to your pool pump filter basket. Save wear on your pump. less leaves end up in your pool filter. A must have if you have even moderate amount of leaves in your pool. eas
Cons: You must clean when full. If your lazy there is no difference with or without this if you dont clean.
Buy It. If you even have a little issue with leaves, I would buy. This must be part of the price if you buy this type of pool cleaner.
