I was wondering if anyone could recommend a good pool vacuum that is not robotic. I can't afford a Dolphin right now but the hose and vacuum attachment I have now is just not cutting it. I was looking at the Pool Blaster Millennium and the Catfish but I see alot of mixed reviews on Amazon. I do plan on purchasing a Dolphin but not until next year. I have a 20x40, inground salt water pool.
