Quick Answer: The Polaris 380 ($749.99 at PoolSupplies.com, $849 at Walmart) is the step-up from the Polaris 280 — same booster-pump-driven design, but with three venturi jets instead of two for stronger propulsion on larger or debris-heavy pools. Home Grail’s review scores it well on build quality (4.3/5), power (4.6/5), and features (4.5/5), landing on an overall 4 out of 5 stars — but its price score is just 2.4/5, and the reviewer flags it outright as “a really expensive pool cleaner, even for a pressure side pool cleaner,” before you even add the required booster pump. It’s a strong pick for large or leaf-heavy inground pools, a hard sell if cost is your top priority.
The 380 comes up constantly across our Polaris coverage — in the best Polaris pool cleaner guide, the Polaris 280 review, and the Polaris troubleshooting guide — always as the triple-jet reference point, never with its own page until now. Here’s what’s actually confirmed about it.

Polaris 380
- Triple venturi jets and all-wheel belt drive give it more propulsion than the 280 for bigger pools and heavier debris loads.
- Cleans floors, walls, and steps in a 3-hour-or-less cycle, per Polaris and PoolSupplies.com.
- Requires a dedicated booster pump (sold separately, not included in the sticker price).
- Home Grail scores it 4.6/5 on power but just 2.4/5 on price — strong performer, expensive total package.

By the numbers
- Price spread: PoolSupplies.com lists the 380 at $749.99; Walmart lists the same F3 model at $849; some retailers price it above $1,098.94. That’s a wider spread than most cleaners on this site — confirm the live price before buying rather than trusting any single figure.
- Jet count confirmed: Polaris’s own lineup and PoolSupplies.com both credit the 380 with three venturi jets, one more than the 280’s dual-jet setup — the actual spec behind the “which model is stronger” question our Polaris 280 review already flagged.
- Home Grail’s component breakdown: Build quality 4.3/5, power 4.6/5, features 4.5/5, but price just 2.4/5 — landing on an overall 4 out of 5 stars, with the reviewer explicitly calling it “a really expensive pool cleaner, even for a pressure side pool cleaner.”
- Cleaning cycle: Per Polaris and PoolSupplies.com, a full cycle takes 3 hours or less, at a travel speed of 20 m/min with automatic reverse.
What it does well
More propulsion than the 280. The third venturi jet is a real functional upgrade, not just a marketing bump — Home Grail’s 4.6/5 power score and its own testing note the 380 completes a whole-pool clean in “approximately two hours” in practice, faster than the spec sheet’s 3-hour ceiling suggests, and its all-wheel belt drive holds traction over the same acorns and twigs the 280 is known for.
Genuinely comprehensive coverage. Unlike suction-only cleaners, the 380 sweeps and vacuums floors, walls, and stairs in one cycle — Home Grail’s review specifically credits it with “comprehensive pool cleaning across floors, walls, stairs, and corners,” backed by an automatic backup valve that reverses direction if it gets stuck rather than stalling in a corner.
Durability with a real track record. Home Grail notes “enhanced durability and reduced maintenance needs,” and the review’s pros highlight owners who report high satisfaction and brand loyalty — a reflection of how long this exact platform has been sold in essentially unchanged form, which also means parts and troubleshooting guidance (see our Polaris troubleshooting guide) are easy to find.
Where it falls short
- It’s genuinely expensive, and the booster pump isn’t included. Home Grail’s 2.4/5 price score is the lowest of any component it measured, and the reviewer states plainly that the 380 “is a really expensive pool cleaner, even for a pressure side pool cleaner” — before factoring in the separate booster pump required to run it at all.
- Price varies unusually widely by retailer. A $749.99-to-$1,098.94+ spread is wider than typical for a pressure-side cleaner this well-established, so shopping around matters more here than with most models on this site.
- Same filtration limits as the 280. The single-chamber filter bag only catches large debris — cloudy water or fine sediment isn’t what this cleaner is built to solve, regardless of the extra jet.
- No app, no mapping. Like every Polaris pressure-side model, the 380 has no smart navigation — it moves via water pressure and jet placement, not a plotted path.
Polaris 380 vs the alternatives
| Model | Jets | Power source | Standout | Price |
|---|---|---|---|---|
| Polaris 380 | Triple venturi | Booster pump required | Strongest propulsion, best for large/leafy pools | $749.99-$849 |
| Polaris 280 | Dual venturi | Booster pump required | Lower-cost entry point | $599.99 sale + booster pump |
| Polaris 360 | N/A (no jet count published) | Existing circulation pump | No booster pump needed | ~$574-679 |
| Polaris VRX iQ+ | N/A (robotic) | Standard outlet | App control, 4WD, fine filtration | ~$1,499 |
Against its own family, the 380 is the power pick — it beats the 280 on raw propulsion and the 360 on cleaning ability, but it costs more than either once the booster pump is factored in. Against Polaris’s own robotic flagship, the same tradeoff Home Grail’s price score highlights applies: the Polaris VRX iQ+ filters more finely, needs no second piece of equipment, and doesn’t demand a separate purchase just to operate. See the full field in our best Polaris pool cleaner guide.
Who should buy the Polaris 380
Buy it if you have a larger or leaf-heavy inground pool, you already have (or are budgeting for) a booster pump, and Home Grail’s power and durability scores matter more to you than the low price score.
Skip it if the booster-pump requirement or the wide price spread is a dealbreaker — the booster-pump-free Polaris 360 or a robotic cleaner with no second-equipment requirement will cost less to own in total.
The bottom line
The Polaris 380 is the strongest pressure-side option in Polaris’s classic lineup — Home Grail’s 4.6/5 power score and 4/5 overall rating back up its reputation as the step-up from the 280 for large or debris-heavy pools. But the same review is just as clear about the tradeoff: a 2.4/5 price score and a wider-than-usual retailer price spread ($749.99 to $1,098.94+) mean you’re paying a real premium for that extra jet, on top of a booster pump the sticker price doesn’t include. For most buyers who don’t specifically need triple-jet propulsion, the Polaris 360 skips the booster pump entirely, and the Polaris VRX iQ+ offers a more modern, single-purchase alternative.
