Hayward Pool Cleaner Parts 2026: Part Numbers, Real Prices & When to Stop Repairing

Quick Answer: Hayward pool cleaner parts split across three unrelated mechanisms. Suction-side turbine cleaners — Navigator Pro and AquaNaut 400/450 — drive on gears and turbines with no diaphragm at all; their priciest single part is the Navigator’s skirt at $438.99, nearly the cost of a whole new unit ($444.99). Hayward’s separate disc-style DV5000 does use a diaphragm (part 3251-005, $81.49), but its body assembly at $746.99 costs more than double the complete $349.00 machine. Pressure-side TriVac 500/700 share a parts platform, with a full hose kit running $496.99 against a $695.99 unit. And robotic TigerShark/TigerShark Plus/QC parts scale with warranty length — Hayward covers the baseline TigerShark for one year and the Plus/QC for three, per Hayward’s own documentation — with power supplies alone running $382.99–$611.99.

Hayward’s lineup looks like one brand but behaves like three completely different repair jobs depending on which cleaner you own. A part number that fits a Navigator Pro means nothing on a TigerShark, and the failure economics — cheap-to-fix versus not-worth-fixing — swing wildly between them. This guide separates the three architectures, gives verified 2026 part numbers and prices, and flags exactly where repairing stops making financial sense.

Hayward parts at a glance

The warranty exclusion list nobody reads

Before ordering anything, know what Hayward will and won’t stand behind. The 2024 Open Line Residential Warranty Terms state that normal wear items are covered “for manufacturing defects only,” and such defects “normally appear within 30 days or less of installation.” Past that narrow window, the named exclusion list is long and specific:

“Basket-strainers, bottom skirts, cartridges, debris bags, discs, fingers, flaps, footpads, grids, hammers, heater elements, light bulbs, o-rings, pleated filter elements, pump seals, shoes, sweep hose rollers, tires, and wings.”

Read that list against this guide and you’ll notice it names almost every part category below — skirts, cartridges, bags, discs. Hayward’s warranty also closes the obvious follow-up: “other parts damaged by worn out wear parts are not covered,” so a stripped tire that chews up a gear train can cost you the claim on the gear train too.

The robotic line carries its own separate schedule. Per Hayward’s TigerShark Series documentation, the baseline TigerShark is warranted for one year, while the TigerShark Plus and TigerShark QC step up to three years. That’s a meaningful gap given the part prices below — a $522.99 QC power supply is a lot cheaper under an active warranty claim than out of pocket.

Suction-side, part one: the turbine-and-gear cleaners

The Navigator Pro and AquaNaut 400/450 are Hayward’s mainstream suction cleaners, and both drive the same way: a turbine spins in the water flow and turns a gear train that rotates the wheels. There is no diaphragm anywhere in this mechanism — a detail worth stating plainly, since some listings and forum posts mislabel Hayward suction parts as “diaphragms” when the real diaphragm design lives in a completely different Hayward product (more on that below).

Navigator Pro

Here’s the number that matters most on this model: the Navigator Pro’s skirt (AXVU016) costs $438.99 — within six dollars of the $444.99 price of an entire new fiberglass-model unit. If a Navigator’s skirt fails outside warranty, replacing the whole cleaner is the obviously better math. Everything else on the Navigator is far more reasonable: the gear box assembly (3259-0001) is $35.49, and a box of 12 replacement hoses shared with the Pool Vac Ultra (HSLCHK120GR) is $239.99.

AquaNaut 400/450

The AquaNaut is Hayward’s 4-wheel-drive step-up suction cleaner, built on the same turbine-and-gear logic with a more robust drivetrain for bigger pools. Its 6-vane turbine kit (PVXH038SA) is $81.49, a drive gear (PVXH007) is $27.49, and its Super Super wheel treads (PVX679PK2) run $106.99 for a pair — the priciest routine wear item in the lineup, reflecting the extra torque a 4-wheel machine puts through its tires. No diaphragm, cartridge, or filter bag appears anywhere in the AquaNaut’s official parts list — like the Navigator Pro, it runs entirely off your pool’s existing pump and filter. See our best suction pool cleaner guide for how these compare to rival brands, and our best inground pool cleaner guide for the AquaNaut’s fit on larger pools.

Suction-side, part two: the diaphragm-disc DV5000

This is the Hayward model that actually does use a diaphragm — a different animal from the Navigator and AquaNaut above. The DV5000 (also badged Kingray) is a disc-style cleaner: a single flexible diaphragm pulses to walk the unit across the pool floor, the same basic concept as a Zodiac Baracuda-style disc cleaner.

A complete new DV5000 (W3DV5000) is $349.00. The diaphragm itself is the cheap, sensible repair at $81.49. The body assembly is not — at $746.99 it costs more than double a brand-new unit, making it the single clearest “just buy a new cleaner” signal anywhere in Hayward’s catalog. The leader hose and cassette assembly sit in an uncomfortable middle ground, each over half the machine’s price, so weigh those against a replacement too.

Pressure-side: TriVac 500 and TriVac 700

Hayward’s pressure-side cleaners connect to a dedicated pressure line, usually through a booster pump, and bag debris in their own filter bag rather than pushing it through your pool’s main filter. The 500 and 700 share almost the entire parts platform — identical wheel kits, hose kit, and swivel kit — so a repair guide for one covers most of the other.

The TriVac 500 currently has a documented tune-up kit (TVX5000TU) bundling several common wear parts at $189.99 — no equivalent bundle is listed for the 700 at time of writing, so 700 owners are better off pricing the individual wheel, roller, and bag parts above rather than searching for a kit that doesn’t exist yet.

Robotic: TigerShark, TigerShark Plus, TigerShark QC

Robotic parts scale with the warranty tier, so it’s worth knowing which TigerShark you own before pricing a repair.

Against a TigerShark QC’s roughly $999 street price, a $522.99 power supply is already over half the machine, and a full motor-and-power-supply failure approaches the cost of buying new. This is exactly why the three-year warranty on the Plus and QC matters so much more than the standard one-year term on the baseline TigerShark — check your model and purchase date before ordering either part. Consumables are a much easier call: the cartridge assembly (3276-081) at $168.99 and the drive belt (3276-050) at $49.49 are routine, sensible maintenance regardless of warranty status. Robotic cleaners are also the only Hayward suction-adjacent models with a real filter of their own — see our best pool cleaner filter guide for how that compares across brands.

Where the official parts resource isn’t

Hayward doesn’t run a consumer-facing parts catalog with searchable part numbers; the populated OEM listings live at specialist retailers — InyoPools, PoolZoom, Sunplay — organized by exact model suffix. That suffix matters more on Hayward than on most brands: the Navigator Pro ships in surface-specific configurations (concrete/gunite as W3925ADC, vinyl as W3925ADV, fiberglass as W3925ADF), and their surface-contact parts — skirts, shoes, pod kits — are not interchangeable between versions. Always match parts to your full model number, not just “Navigator Pro” or “TriVac,” before ordering.

The bottom line

On the Navigator Pro and AquaNaut, buy turbine kits, gears, and wheel treads freely — they’re inexpensive relative to the machine. But stop at the skirt: $438.99 against a $444.99 unit is a new-cleaner decision, not a repair. On the DV5000, the diaphragm at $81.49 is a normal, sensible fix; the $746.99 body assembly against a $349.00 unit is not. On the TriVac 500/700, wheels and bags are worth buying, but a full hose kit at $496.99 eats 71% of the unit price. And on any TigerShark, check your warranty tier before ordering a power supply or motor unit — the difference between the standard one-year and the Plus/QC’s three years is worth hundreds of dollars in these parts alone.

Whatever you’re repairing, price the part against a new unit first. Curious what a new Hayward would cost instead?
