It looks like the Tigershark I've had for the last 11 years is finally biting the dust. It needs a new motor and I'm thinking it's probably better to just buy a new one rather than sink that much money into one that's breaking down. What pool vac does everyone recommend? I have a 20 x 40 Grecian shaped pool. The outlet is down by the deep end of the pool if that matters. I found that the Tiger shark frequently missed spots on the shallow end of the pool with the angled walls of the Grecian shape. Would it be worth it to upgrade to a remote controlled model to go back and get the missed spots?
