the Phantom is pressure driven and needs abooster pump to operate .I bought the Phantom at Leslie's online last year in December for $599, it came with a free Hayward booster pump, and $100 mail in rebate .i sold the boosetr pump on Ebay for $145 as I had one from my old Polaris 380 days . so the total cost was $354 delivered.
The Phantom uses hard hoses so it doesn't tangle itself up.and has three modes of operation
1)Bottom only
2) Skims the surface only
3) Auto: 13 minutes on the bottom, comes up and skims the top for 7 minutes , starts cycle over again.
