Bests & Worsts Reviews from Amazon

I was looking for a low priced efficient auto pool cleaner to replace my ever-dying, undependable, expensive to repair Hayward Navigator. Reading the reviews of the GW9500 on Amazon, it seemed that only 1/3 of the reviewers were dissatisfied with the performance of the GW.I found it on Ebay for 289.00, w/free shipping and a 50.00 rebate from Pentair; so I took a 240.00 chance. Connected the hoses, dumped the GW9500 in the pool, then turned the pump on. It was that easy. I have a screen enclosed kidney shaped pool 30x16 with 6ft depth, gunite pool with no swim outs,three steps in the shallow end and a ladder in the deeper end. The pool is spotless, the GW9500 never gets stuck, evenly cleans, and it scours the walls like a Catfish. I leave it in the pool and it cleans with each cycle of the pool pump. All I do is add chemicals to the pool; the GW9500 does the rest. Worthy of mention, I fired my pool service that charged 95.00 a month. Update 05/26/2011: Still working great; pool sparkles. Glad I chose the GW9500. Update: I found that when the water line drops too low, the GW sticks at the steps. Easy remedy to fill the pool. Update 6/12/2013: GW has been used every day since purchase and has never needed replacement parts, or service. It has been very dependable and totally trouble free.
