Your pool pump is almost certainly the most expensive thing to run in your backyard — often the second-biggest electricity draw in the entire house, behind only heating and cooling. The good news: a variable-speed pump does the exact same job for a fraction of the power, and since 2021 it’s what you’ll be buying anyway. This is a pound-for-pound guide to the best variable-speed pumps of 2026, with the one thing every other roundup leaves out: a calculator that shows what switching actually saves you.
How much could a variable-speed pump save you?
The pump is the biggest energy hog in your pool. A variable-speed pump moves the same water for a fraction of the power. Set your own numbers — the math updates live.
Estimate only — your rate, run time, and pump efficiency vary. Variable-speed pumps cut pumping energy roughly 70% by running slower for longer (pump power scales with the cube of speed; DOE / ENERGY STAR). Single-speed wattage shown is typical motor input power, not nameplate HP.
The short version:
🏆 Best overall: Pentair SuperFlo VS (1.5 HP) — the most-reviewed VS pump here (4.4★, 1,820 ratings) and the cheapest of the major brands at about $1,300. Three programmable speeds, ENERGY STAR, fits most inground pools.
💎 Best premium: Hayward TriStar VS (1.85 THP) — a high-flow workhorse for large or high-head pools at about $2,200. Fully programmable, ENERGY STAR, 4.6★.
💸 Best budget: AQUASTRONG VS (1.5 HP) — the cheapest way into variable speed by a wide margin at about $699, and it fits in-ground or above-ground pools (4.7★, 146 ratings). The trade-off is an off-brand with no dealer network.

Best overall: Pentair SuperFlo VS
Best overall · The most-reviewed variable-speed pump and the cheapest of the major brands — 1.5 HP, three programmable speeds, ENERGY STAR, fits most inground pools
Your pick if you want the safe default — the most-proven variable-speed pump (4.4★ across 1,820 owners), ENERGY STAR, and the cheapest of the major brands, sized for most standard inground pools on the 230V you likely already have.

- Cheapest of the trusted major brands (~$1,300) — and the most-reviewed VS pump here at 4.4★ across 1,820 ratings
- Three programmable speeds with a 24-hour clock and override — set it and forget it
- ENERGY STAR certified; 112 GPM max flow suits most residential inground pools
- Drop-in replacement for a worn-out single-speed pump
- 230V only — most pool pads have it, but confirm before you buy
- 1.5 HP fits standard pools; very large or high-head setups want the Hayward TriStar VS
- Digital keypad, not Wi-Fi/app control (step up to Pentair's IntelliFlo for that)
The SuperFlo VS is the default variable-speed pump for a reason: it’s the cheapest of the trusted major brands and the most-reviewed pump in this guide, with 1,820 ratings at 4.4 stars. You get three programmable speeds, a 24-hour clock, and an override button, so you set a low cruising speed for daily filtration and a higher burst for vacuuming or running a heater. ENERGY STAR certified, 112 GPM of max flow, and it drops in where a worn-out single-speed used to sit. For most residential inground pools, this is the one to buy — and the calculator above shows why it pays for itself fast.
Best premium: Hayward TriStar VS
Your pick if you've got a large or high-head pool — the 1.85 HP of headroom and a 4.6★ owner rating earn the premium; on an average-size pool it's more pump than you need.
- 1.85 THP with high flow — handles large pools, long pipe runs, water features, and in-floor cleaning that 1.5 HP pumps strain on
- Fully programmable variable speed; ENERGY STAR certified
- Strong owner rating (4.6★ across 305) plus Hayward's dealer and parts network
- Most expensive here (~$2,200) — more pump than an average-size pool needs
- 230V and a larger footprint — confirm your pad and plumbing
- You pay for headroom you may not use on a standard pool
When 1.5 HP isn’t enough, this is the step up. The TriStar VS is a 1.85 total-HP, high-flow pump built for large pools, long plumbing runs, water features, and in-floor cleaning systems that make a smaller pump work too hard. It’s fully programmable and ENERGY STAR certified, with a 4.6-star owner rating and Hayward’s dealer and parts network behind it. The catch is price: at about $2,200 it’s more pump than an average-size pool needs, so only size up if your pool actually demands the extra flow.
Best budget: AQUASTRONG VS
Your pick if you want variable-speed savings for the least money — about $699, fits in-ground or above-ground, and a strong 4.7★; the trade is an off-brand with no dealer network behind it.
- Cheapest path to variable-speed savings by a wide margin (~$699 vs $1,300+ for the majors)
- Strong owner rating (4.7★ across 149) and works for in-ground OR above-ground pools
- Self-priming with a built-in filter basket; 115/230V wiring flexibility
- Off-brand — no Pentair/Hayward dealer network, and long-term parts and warranty support are the open question
- Far fewer reviews (146) than the majors — less of a long-term track record
- Max flow isn't published; size carefully for larger pools
If the majors’ prices are the only thing keeping you on a single-speed pump, this is the way in. At about $699 the AQUASTRONG is less than half the price of the Pentair, it’s self-priming with a built-in filter basket, and it runs on 115V or 230V — and unlike the inground-only majors, it fits above-ground pools too. Owners rate it 4.7 stars across 146 reviews, which is genuinely strong. Be clear-eyed about the trade-off, though: it’s an off-brand, so there’s no Pentair/Hayward dealer network and the long-term parts and warranty story is the open question. For a smaller pool or a tight budget, the savings start the day you plug it in.
How to choose: single-speed vs. variable, sizing, and run time
Variable-speed is the whole point — and the savings are real. A single-speed pump runs flat-out whenever it’s on. A variable-speed pump moves the same water at a much lower RPM, and because pump power drops with the cube of speed, halving the speed cuts the power to roughly an eighth. Run it longer at that low speed and you still come out far ahead — the DOE and ENERGY STAR peg the savings at up to ~70%. That’s the number the calculator above is built on.
Size to the pool, not the ego. A bigger motor doesn’t clean better; it just wastes more energy and strains your plumbing. Most residential inground pools are well matched to a 1.5 HP variable-speed pump (the Pentair SuperFlo VS). Step up to 1.85+ total HP (the Hayward TriStar VS) only for a large pool, long pipe runs, water features, or an in-floor cleaning system.
Mind the voltage and the run time. The two major pumps here are 230V — almost every pool pad has it, but confirm before you buy; the AQUASTRONG takes 115V or 230V. For how long to run it, aim for one to two full water turnovers a day. With variable speed you’ll run more hours at low RPM than you did on single-speed, and that’s fine — the low-RPM hours are cheap, which is exactly where the savings live. Many utilities also offer rebates on variable-speed pumps, so check yours before you buy.
FAQ
How much does it cost to run a pool pump?
A single-speed 1.5 HP pump running 8 hours a day at about $0.17/kWh costs roughly $900–$1,000 a year — often the biggest electricity load in the whole house. A variable-speed pump doing the same job runs closer to $250–$350. Use the calculator above with your own rate and run time to see your number.
Are variable-speed pool pumps worth it?
For almost everyone replacing a single-speed, yes. The DOE and ENERGY STAR put the energy saving at up to ~70%, because pump power drops with the cube of motor speed — running slower for longer moves the same water for a fraction of the power. Most variable-speed pumps pay for themselves in one to two seasons, and many utilities offer rebates on top.
Are variable-speed pool pumps required by law?
Largely, yes. Since the U.S. Department of Energy's pool-pump rule took effect in July 2021, most replacement pumps of 1 HP and up sold in the U.S. are variable-speed, and several states (California, Florida, Arizona) mandate them outright. If you're replacing a dead single-speed, you'll almost certainly be buying variable-speed anyway.
What size (HP) pool pump do I need?
Size to your pool's volume and plumbing, not to 'bigger is better' — an oversized pump just wastes energy. Most residential inground pools are well served by a 1.5 HP variable-speed pump like the Pentair SuperFlo VS. Large pools, long pipe runs, water features, or in-floor cleaning systems want 1.85+ total HP, like the Hayward TriStar VS.
How many hours a day should I run my pool pump?
Aim for one to two full turnovers of your water per day. With a single-speed that's about 8 hours at full power; with a variable-speed you run longer at low RPM, and that low-RPM time is exactly where the savings come from. The calculator above assumes 8 hours by default — adjust it to your routine.
