Pros
- Built-in Wi-Fi and Bluetooth: schedules and speed from the Pentair Pool app with no automation system
- Holds a set flow rate as the filter loads up, so turnover stays where you set it
- Enough head and flow for spas, waterfalls and large pools
- 3-year warranty when a pro installs it
Cons
- 230 V only, so it can’t drop onto a 115 V circuit
- Least efficient of Pentair’s current pumps per its rating (WEF 7.1)
- No keypad for schedules unless you add the touchscreen
