I have a The PoolCleaners 2 wheel cleaner and was looking for aftermarket parts. I was looking for an elbow and a variable suction adjuster. I found some on Amazon but wasn't sure if it would be compatible with the The PoolCleaer. Have you guys used aftermarket parts from Amazon to replace The Poolcleaners parts? Can you guys provide any reputable sellers on Amazon that sells parts for The Poolcleaners?
