Also know as the Barracuda, this cleaner is designed to vacuum debris from your pool but does not like a lot of leaves or any sticks. The advantage to a G4 is that is only has one moving part. It is a diaphragm that does last a long time unless in ingest a stick or some other object that can tear it. The G4 can get stuck on ladders, steps and sometimes other parts of the pool. Overall it is not a bad cleaner best used on a screened in pool with limited vegetation growth around the pool.
