the $1,253-vs-$2,199 variable-speed question — and the Hayward now holds our crown
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
These two have now both held the top of our variable-speed board, which makes this the cleanest comparison of what each one is for. Our variable-speed showdown is a pound-for-pound roundup, so it bills picks by role rather than ruling pairs; this page is a tale of the tape. The Pentair SuperFlo VS was our best overall from June to September 2026, on proof and price: 4.4★ on a base now 1,842 ratings deep, at about $1,253 when we read it on 8 October. The Hayward TriStar VS has held the crown since 8 October 2026, on the top owner score in the field — 4.7★ across 310 ratings, with the smallest critical share — at $2,199. In between, the BLACK+DECKER 1.5 HP VS held it for a month, until both BLACK+DECKER pumps went unbuyable. What changed is availability, not the machines. Pentair discontinued the SuperFlo VS in August 2026 and names the SuperFlo VST as its replacement; on 8 October its buy box read "Only 3 left in stock", though eleven sellers still listed it under See All Buying Options. On paper the Hayward is the bigger pump and that is what the extra money buys: 1.85 total HP with high flow that replaces up to a 2.0 HP pump, against the Pentair's 1.5 HP nameplate (2.2 total HP) and 112 GPM. Both are 230V and both are in-ground pumps. The TriStar is on the EPA's ENERGY STAR list as Hayward SP3202VSP; the EPA's dataset carries the Pentair's model number EC-342001 under the name SuperFlo VST, so confirm that one with your utility before counting on a rebate. Two catches belong to the Hayward. On a standard pool it is headroom you pay for and never use. And the seller Amazon puts in its buy box, PoolGoods, has no row on Hayward's published list of authorized online sellers, while Pool Supplies Superstore, on the same listing, is marked as authorized for Amazon — buy from that one. Its critical reviews are few, and they describe a motor Hayward sells only as a whole power end.
What would decide it
- Owner proof: Pentair SuperFlo VS Variable-Speed Pool Pump (1.5 HP, EC-342001) reads 4.4★ across 1,842 owners; Hayward TriStar VS Variable-Speed Pool Pump (1.85 THP, W3SP3202VSP) reads 4.7★ across 310. Depth of sample matters as much as the star.
- The money: Pentair SuperFlo VS Variable-Speed Pool Pump (1.5 HP, EC-342001) streets ~$1,253, 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 1,842 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 1,842 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 (~$1,253) — and the most-reviewed VS pump here at 4.4★ across 1,842 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 buy box read "Only 3 left in stock" on 2026-10-08, with eleven sellers still listed under See All Buying Options. It lost our crown on that stock clock in September. 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
- Digital keypad, not Wi-Fi or app control
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 310) plus Hayward's dealer and parts network
- The most expensive pump here, and more pump than an average-size pool needs
- The buy-box seller (PoolGoods) has no row on Hayward's own list of authorized online sellers, and Hayward's warranty is for authorized sellers only — open See All Buying Options and choose Pool Supplies Superstore, which Hayward's list marks as authorized for Amazon
- 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 310 base (about 5.5%, the smallest share in this field), re-read 2026-10-08 with nothing newer than January 2025; of the first 10, 4 describe a motor or early failure, 3 shipping damage on arrival, 2 absent customer service or documentation · critical reviews read October 2026
FAQ
Which is better, the Pentair SuperFlo VS or the Hayward TriStar VS?
For most buyers in October 2026, the Hayward, because you can still buy it. It holds our showdown's best overall: 4.7★ across 310 ratings, ENERGY STAR, $2,199. The Pentair was our pick from June to September on a deeper base (4.4★ across 1,842) and a lower price (about $1,253), but Pentair has discontinued it and the buy box read "Only 3 left in stock" on 8 October. The Hayward is also the bigger pump, 1.85 total HP with high flow, so on an average pool it is more than you need.
Is the TriStar VS worth about $950 more?
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 inground pool it is more pump than you need. Buy it from Pool Supplies Superstore on the listing — Hayward's authorized-seller list names that seller for Amazon and has no row for the buy-box seller.
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, well-proven pump at about $1,253 with 1,842 ratings behind it. It is no longer our pick because the supply is ending: the buy box read "Only 3 left in stock" on 8 October 2026. Do not buy the marketplace "SuperFlo VST" listings in its place — the ones we found in September misspell the brand as "Penteir", read "Brand: Generic" in their own spec table, and carry nine ratings at $1,459.
