Detailed pump reviews and technical trade-offs
Each recommendation uses the same locked review format. Specifications below are manufacturer-published where identified; confirm the specific voltage, model revision and pump performance curve before ordering.
Pentair IntelliFlo3 VSF 1.5 HP (011065)
App-based scheduling plus variable-flow regulation make this a compelling smart option when a 1.5-THP pump fits the system.
Manufacturer lists WEF 9.4, dual-voltage input and Pentair Pool app control; adjustable flow helps maintain target circulation as conditions change.
Higher initial expense; 1.5 THP is not suitable for every plumbing layout or spa feature; professional commissioning is advisable.
Technical Specifications
What matters in everyday operation
The 1.5-HP IntelliFlo3 stands out because Pentair publishes a 9.4 weighted energy factor for SKU 011065. Its app-connected variable-flow controls can simplify scheduling and circulation management, but the WEF rating is a standardized test metric, not your predicted utility bill. Check required gallons per minute at actual total dynamic head before specifying it.
Energy savings depend on running the pump at the lowest speed that still supports filtration, heater minimum flow, skimmers, chlorination and other equipment. A licensed pool professional should verify wiring, bonding, protection and hydraulic sizing.
Best reason to consider: App-based scheduling plus variable-flow regulation make this a compelling smart option when a 1.5-THP pump fits the system.

Pentair SuperFlo VST (342002)
A straightforward variable-speed upgrade with a built-in display and dual-voltage flexibility for common replacement projects.
Pentair publishes WEF 9.0 at 230 V, 7.3 at 115 V; simple local keypad; designed for common SuperFlo and Super Pump replacements.
Efficiency rating depends on supply voltage; plumbing and electrical fit must be checked; not a universal drop-in.
Technical Specifications
What matters in everyday operation
SuperFlo VST is appealing when the goal is to replace an older pump without paying for every connected feature. Pentair lists a 2.2-THP motor and separate WEF figures at 115 and 230 volts. It is particularly important not to quote the 230-volt efficiency figure for a 115-volt installation. Verify hydraulic requirements and current installation details.

Hayward TriStar VS 900 (SP32900VSP)
A Hayward variable-speed platform with documented 1.85-THP configuration and a broad programmable speed range.
Hayward brochure identifies 1.85 THP, 600–3450 RPM and dual-voltage operation; strong candidate for a matched hydraulic installation.
Confirm exact VS 900 SKU versus Omni versions; pump sizing and control compatibility require installer review.
Technical Specifications
What matters in everyday operation
The TriStar VS 900 is a strong option for owners who want to prioritize pump efficiency but already have compatible Hayward plumbing. Hayward documents a 1.85-THP model, dual-voltage operation and a 600–3450 RPM range. The VS 900 and VS 900 Omni are different purchasing configurations; compare exact part numbers and control requirements.

Jandy VS FloPro 2.7 HP (VSFHP270DV2AS)
A compact variable-speed pump with substantial capacity for pools with multiple hydraulic features and tight equipment pads.
Jandy confirms dual-voltage design, 2.7-HP class and two auxiliary relay connections; compact FloPro footprint.
A high-capacity pump may be unnecessary for basic filtration; control and professional installation choices matter.
Technical Specifications
What matters in everyday operation
Jandy positions this VS FloPro model as a space-saving pump for more demanding pools and spas. The manufacturer documents a 2.7-HP class motor, dual-voltage capability and auxiliary relays. Those features only justify the investment when the plumbing, filtration, heater and water-feature demands call for them. Do not assume higher horsepower means lower electricity use.

Hayward MaxFlo VS 500 Omni (HL2350020VSP)
A variable-speed pump bundled with the VS Omni ecosystem for owners who want remote scheduling and equipment control.
Hayward lists 1.65 THP, WEF 10.7/10.2 and 600–3450 RPM; remote VS Omni control extends beyond pump speed.
Manufacturer brochure states not sold online; confirm exact package, control hardware and installer quote before buying.
Technical Specifications
What matters in everyday operation
MaxFlo VS 500 Omni combines a relatively compact pump with remote-control functionality. Hayward publishes 1.65 THP, a 600–3450 RPM range and dual-voltage WEF values of 10.7 and 10.2. The manufacturer explicitly describes the Omni package as not sold online, so an Amazon search is only a model-identification convenience—not evidence that an authorized listing exists.

How to choose a variable-speed pool pump that actually saves energy
1. Size by flow and head, not horsepower alone
A pump must overcome plumbing friction and equipment restrictions. Ask for required GPM at actual total dynamic head, and compare pump curves. Oversizing can raise cost and cause filtration or noise issues.
2. Compare the correct WEF and voltage
WEF represents standardized efficiency. Higher values generally indicate better rated efficiency, but compare similar applications and confirm whether the published value is for 115 V or 230 V.
3. Plan a low-speed filtration schedule
Most savings come from operating at lower speed for more hours when the system permits. Do not drop below heater, salt-cell, skimmer or sanitation minimum-flow requirements.
4. Check wiring, unions and pad footprint
Voltage, breaker capacity, bonding, inlet/outlet size, plumbing height and available clearance can make a seemingly affordable pump a costly retrofit. Hire a qualified installer.
5. Evaluate automation only if useful
Wi-Fi control, flow targets and relays can simplify operation, but basic programmable variable-speed pumps can still deliver meaningful savings. Consider serviceability and your existing automation.
6. Compare lifetime cost and service access
Include purchase, installation, electricity, rebates, parts, warranty and the availability of local service. Avoid unverified claims of guaranteed percentage savings.
Energy-efficiency checklist before ordering
Keep a baseline of current pump wattage and operating hours. After installation, measure actual power and adjust the schedule while maintaining required water turnover and sanitizer operation.
How to estimate pool pump operating cost
Annual energy cost ≈ pump watts ÷ 1,000 × daily operating hours × 365 × electricity price per kWh. For variable-speed schedules, calculate each speed block separately and add them. Example: 300 W for 10 h/day at $0.18/kWh costs about $197/year; this is an illustration, not a forecast for a listed model.
Frequently asked questions
Does a variable-speed pump always save money?
Usually it can reduce electricity use compared with running an oversized single-speed pump, but savings depend on schedule, hydraulic load, local electricity rate and installation. No savings percentage is guaranteed.
What is WEF on a pool pump?
Weighted Energy Factor is the standardized pool-pump efficiency metric used in US labeling. Compare the exact SKU and voltage rating, and still use the manufacturer pump curve to confirm hydraulic fit.
Is a higher-horsepower pump more efficient?
Not necessarily. Extra horsepower can be useful for high-flow features but can waste money if the pump is oversized. Match flow at head and then optimize speed and runtime.
Can I replace a 230-volt pump with a 115-volt model?
Only when the selected pump supports that voltage and the circuit, wiring and hydraulic performance meet requirements. Some pumps publish different WEF ratings at different voltages.
Should I run my variable-speed pump 24 hours a day?
Not automatically. The right schedule depends on required circulation, sanitation, debris, water features and energy rates. Use low-speed operation when appropriate and confirm minimum flow for connected equipment.
Are smart app controls worth paying for?
They can help with remote schedules and diagnostics, but a well-sized pump with reliable onboard programming may be a better value if you do not need automation.
Final recommendation
Best connected moderate-capacity option: Pentair IntelliFlo3 VSF 1.5 HP (011065), when its flow/head curve matches your pool and you want app-based control.Best practical replacement: Pentair SuperFlo VST (342002), particularly when the existing equipment layout supports a straightforward installation.Best Hayward automation option: MaxFlo VS 500 Omni. For more hydraulic capacity, compare Jandy VS FloPro 2.7 HP and Hayward TriStar VS 900 after professional sizing.
