Pros
- Cheapest of Hayward’s OmniX pumps
- Runs on 115 or 230 V, so it swaps in for most old pumps
- Schedules and speeds from a phone over Bluetooth with no automation system to buy
Cons
- No keypad: schedules must be set in the OmniX app
- Doesn’t connect to Pentair or Jandy automation
- Not ENERGY STAR certified, so it may not qualify for utility rebates
