Polaris or Paramount?--which keeps your pool cleaner with less hassle?

[Trish29]

I'm in the process of checking out fiber glass IG pools and one company sells this Paramount in floor cleaning system priced at $4K. http://www.paramountpoolproducts.com/

They claim one will spend approx 80% of the 4K within about four years of owning the Polaris as we were told that it is repair part intensive. Does anyone have any model Polaris (or any other pool cleaner recommendation) that you use in your pool and whether or not you've had to replace parts and at what cost? I just think the cost of this Paramount vs paying about $1000 for another good cleaner might be a more of aploy to get an unsuspecting person to spend money, more than it is about efficiency.
