Hello, I have owned a pool for about a year and after my first season I decided to purchase a pool cleaner.  I got the Hayward Aquanaut 400 and it worked for about a week.  After troubleshooting for a couple of weeks I believe the issue is not enough suction from the pump.  I am curious if I can just upgrade the motor to a larger hp motor to accommodate the pool vacuum.  I have tried shutting off the central drain and only going through the basket drain, to no avail.  

Current Setup

Pentair FNSP48 DE Filter

Hayward (XXXXXXX) 1 hp pump.

Polaris booster pump for Polaris leaf cleaner. (No Longer used as I wanted something that would scrub the walls.)


Any help would be appreciated.
