I know pressure vs suction but I am just tired of the Polaris money pit. I am constantly replacing parts and am hesitant to buy a new Polaris because I was only happy with my 380 for the first year(had it for 6 or 7 years). It never really seemed to get the job done(missed too many spots), gets stuck, something is always breaking or needs replacing, hose, quick connect, backup valve, wheels, belts, pump, bag. Polaris needs quick connect valve and new tires right now as well as a new hose. My pool is inground with diamond brite finish, 17k gallons. Do you think I would be happy with the Baracuda MX-8 instead. Lately I been hand vacuuming but I'm getting tired of that. I will be hooking the MX-8 up to the skimmer.
