Tale of the tape — this fight hasn't been booked yet
No showdown has ruled between these two. What follows is the verified data, not a verdict.
Ringside notes
Our variable-speed pump showdown carded both of these, ruled for the Pentair SuperFlo VS as best overall in June 2026, and then moved the crown in September — not to the Hayward, but to a third pump. Read the original ruling first, because it still explains the two machines. The Hayward posts the HIGHER owner score, 4.7★ against the Pentair's 4.4★, so the ruling never went to the better-rated pump. It went to the better-PROVEN one: the Pentair's 4.4★ sits on 1,834 ratings against the Hayward's 308, a base six times deeper, at about $1,280 against $2,199. On paper the Hayward is the bigger machine and that is exactly what you are paying for: 1.85 total HP with high flow that replaces up to a 2.0 HP pump, against the Pentair's 1.5 HP nameplate and 112 GPM. Both are 230V, both ENERGY STAR certified, both in-ground pumps. So the split is size, not quality — the Hayward earns its premium on a large pool, a long pipe run, water features or in-floor cleaning, and on a standard pool it is headroom you buy and never use. Then the clock ran out on our own winner. Pentair discontinued the SuperFlo VS in August 2026 and names the SuperFlo VST as its replacement; we kept the pick with a disclosure while it was easy to buy, and on 4 September the listing read "Only 2 left in stock". A pump you may not be able to buy next month is not a recommendation, so the crown moved to the BLACK+DECKER 1.5 HP VS ($999.99, 4.3★ across 411 clean ratings, a 2026 hands-on test behind it) and the Pentair stays on the page as the outgoing model. The Hayward TriStar VS kept its premium billing throughout: its critical reviews are the smallest share in the field (17 of 308), and the failure they describe is the motor, which Hayward sells only as a whole power end. If your pool needs the TriStar's flow, nothing that happened to the Pentair changes that answer.
What would decide it
- Owner proof: Pentair SuperFlo VS Variable-Speed Pool Pump (1.5 HP, EC-342001) reads 4.4★ across 1,834 owners; Hayward TriStar VS Variable-Speed Pool Pump (1.85 THP, W3SP3202VSP) reads 4.7★ across 308. Depth of sample matters as much as the star.
- The money: Pentair SuperFlo VS Variable-Speed Pool Pump (1.5 HP, EC-342001) streets ~$1,280, Hayward TriStar VS Variable-Speed Pool Pump (1.85 THP, W3SP3202VSP) ~$2,199 — MSRPs, not sale lows, decide the tier.
- Pentair SuperFlo VS Variable-Speed Pool Pump (1.5 HP, EC-342001) — your pick if: you want the most-proven variable-speed pump ever sold on Amazon (4.4★ across 1,834 owners) and can live with buying the last of a discontinued run — it lost our crown in September 2026 because a pick you may not be able to buy next month is not a pick.
- Hayward TriStar VS Variable-Speed Pool Pump (1.85 THP, W3SP3202VSP) — your pick if: you've got a large or high-head pool — the 1.85 HP of headroom and a 4.7★ owner rating earn the premium; on an average-size pool it's more pump than you need.
The full cards
Your pick if you want the most-proven variable-speed pump ever sold on Amazon (4.4★ across 1,834 owners) and can live with buying the last of a discontinued run — it lost our crown in September 2026 because a pick you may not be able to buy next month is not a pick.
- Cheapest of the trusted major pool brands (~$1,280) — and the most-reviewed VS pump here at 4.4★ across 1,834 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
- ⚠️ DISCONTINUED AND NEARLY GONE — Pentair names the SuperFlo VST (342002) as the replacement, and the Amazon listing read "Only 2 left in stock" on 2026-09-04. It lost our crown on that stock clock. If it is in stock when you read this it is still a genuine, well-proven pump; if it is not, do not buy the "Penteir"-titled VST from a marketplace reseller in its place
- 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 or the 3 HP BLACK+DECKER
- Digital keypad, not Wi-Fi/app control — the BLACK+DECKER that replaced it as our pick has both
Water finds its way into the control head and kills the drive unit - three owners describe exactly that, one within a week - and the survivors tend to go at three to five years. Pentair's warranty also requires a licensed installer.
3 of the first 10 critical cards (of 192) are water in the control head and 2 more are a drive failure at three to five years; the licensed-installer warranty condition is named separately · critical reviews read August 2026
Your pick if you've got a large or high-head pool — the 1.85 HP of headroom and a 4.7★ 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 (4.7★ across 308) 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
The motor is the failure, and Hayward's parts policy is the cost: bearings gone after a flood, a pump dead at 14 months, one owner on a third motor in five years — and the motor "cannot be purchased alone", so the fix is the whole power end at about $1,199. A second cluster is shipping damage on arrival (torn boxes, a broken control housing), and owners describe Hayward support and programming documentation as thin.
17 critical reviews against a 308 base (about 5.5%, the smallest share in this field); of the first 10 read, 4 describe a motor or early failure, 3 shipping damage on arrival, 2 absent customer service or documentation · critical reviews read September 2026
FAQ
Which is better, the Pentair SuperFlo VS or the Hayward TriStar VS?
Our showdown ruled for the Pentair SuperFlo VS as best overall in June 2026, on proof and price: 4.4★ across 1,834 ratings at about $1,280, against the Hayward's 4.7★ across 308 at $2,199. The Hayward scores higher on a base six times thinner, for about $900 more, and it is the bigger pump — 1.85 total HP with high flow. Buy the Hayward when the pool needs it. But note the Pentair has since been discontinued and lost our crown to the BLACK+DECKER 1.5 HP VS; it is on the page as the outgoing model.
Is the TriStar VS worth the extra $900?
Only if your pool asks for it. The TriStar is 1.85 total HP with high flow and replaces up to a 2.0 HP pump; the SuperFlo is a 1.5 HP nameplate at 112 GPM. On a large pool, a long pipe run, water features or in-floor cleaning that is real headroom. On an average-size inground pool it is more pump than you need, and both are ENERGY STAR certified, so the savings case is much the same either way. Its owners' one recurring complaint is that a failed motor is sold only as a whole power end.
Should I still buy the SuperFlo VS now that Pentair has discontinued it?
If you can find one in stock, it is still a genuine, very well-proven pump at about $1,280 with 1,834 ratings behind it. It is no longer our best overall because you probably cannot: the Amazon listing read "Only 2 left in stock" on 4 September 2026, which is why the crown moved to the BLACK+DECKER 1.5 HP VS. Do not buy the marketplace "SuperFlo VST" listings in its place — the ones we found misspell the brand as "Penteir", read "Brand: Generic" in their own spec table, and carry nine ratings at $1,459.
