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

Quick Answer: Dolphin (Maytronics) pool cleaner parts share numbering across the Nautilus CC Plus, Premier, and Liberty lines, but prices vary sharply by category and — unusually for this niche — by retailer for the identical part number. Filter cartridges run $69.99–$139.99, standard brushes $39.99–$43.99, and a power supply $209–$400 depending on model and where you buy it. The one number that should stop you cold: a replacement Dolphin Liberty battery costs $1,036.99 through InyoPools — more than a brand-new Liberty 300 robot at roughly $999. Maytronics’ own warranty excludes only brushes and filter bags, a shorter exclusion list than most competing brands.

Dolphin’s part catalog looks straightforward — one brand, mostly shared numbering — but two things trip up owners searching for parts: prices for the exact same part number swing depending on whether you buy from Maytronics directly or an authorized dealer, and one specific part (the Liberty’s battery) costs more than the machine it powers. This guide gives verified 2026 part numbers and prices across the main Dolphin lines, flags the retailer spread, and tells you when repairing stops making financial sense.

The retailer price spread nobody warns you about

This is the single most useful thing to know before ordering any Dolphin part: the same part number is not the same price everywhere, and there’s no consistent “always cheaper” retailer.

On the power supply, Maytronics’ own store is currently running a sale that undercuts InyoPools by nearly $135. On the cable — the identical part number — InyoPools is over $50 cheaper. Neither retailer wins consistently, which means the only reliable strategy is to look up your exact part number at both maytronics.com and an authorized dealer like InyoPools before you buy, every time.

Nautilus CC Plus: filters, brushes, and tracks

The Nautilus CC Plus is Dolphin’s best-selling model, and its parts are the most widely stocked. Filtration is the part you’ll replace most often: the ultra-fine cartridge kit (9991432-ASSY, $82.99 for 4) handles fine debris, while the fine filter cartridge (9991428-ASSY, $69.99) and a seasonal Spring/Fall kit (9991433-ASSY, $68.99) round out the filtration options depending on what your pool is dealing with.

Drivetrain parts are inexpensive by comparison. The standard full brush (3295-046) is $43.99, a timing track set (3295-133) is $46.49, and the drive pulley (3295-456) is $27.49 — all routine, sensible maintenance regardless of warranty status. The motor unit (99953051-EX) is the priciest single component at $342.99, which is worth checking against your CC Plus’s remaining warranty before ordering out of pocket, since a full CC Plus retails for around $799 new. See our Dolphin Nautilus CC Plus review for the complete spec breakdown and our best Dolphin pool cleaner guide for how it compares to the rest of the lineup.

Premier: swappable filtration means swappable parts

The Dolphin Premier’s whole pitch is swappable multi-media filtration, and that shows up in its parts list too. Instead of one filter type, Premier owners choose between the ultra fine filter media kit (3295-327, $83.99 for 4 cartridges), a filter bag conversion kit (99954305-RK1, $88.99) for heavy leaf loads, and a standalone 70-micron replacement bag (PL4305, $44.77) for the bag setup. That flexibility is genuinely useful if your debris load changes by season, but it also means Premier owners need to know which filtration mode they’re running before ordering — an ultra-fine cartridge doesn’t fit where a filter bag does.

Brush and drivetrain parts are shared with the CC Plus platform (same 3295-046 brush, same 3295-133 timing track), so most wear-item repairs use identical numbers across both models. The Premier’s power supply assembly (9995678-US-ASSY) is the same part flagged in the retailer-spread table above — check both Maytronics and InyoPools before ordering.

Liberty: where the battery costs more than the robot

This is the number that should change how you think about repairing a cordless Dolphin. The Liberty battery (part 5652292LF-ASSY) is $1,036.99 through InyoPools — and it’s frequently listed out of stock. A complete new Dolphin Liberty 300 sells for roughly $999. There is no version of this math where replacing a dead Liberty battery out of pocket beats simply buying a new cordless robot; the battery alone costs more than the entire machine it powers.

If your Liberty’s battery fails and it’s still within Maytronics’ warranty period, get it replaced under warranty rather than paying out of pocket. If it’s out of warranty, price a new Liberty 300 before you order the battery — in almost every case the new-unit math wins. See our best cordless robotic pool cleaner guide for how the Liberty compares to Aiper, Beatbot, and WYBOT’s cordless models, all of which use less expensive proprietary batteries.

What Maytronics’ warranty actually excludes

Compared to some rival brands, Maytronics keeps its wear-item exclusion list short. Per Maytronics’ own warranty terms, as cited by authorized dealer Epic Pool Supply:

“Normal wear to Wonder Brushes, Combined Brushes and filter bags are excluded from this warranty.”

That’s it — brushes and filter bags. Everything else, including motors, power supplies, tracks, and cartridges, is covered for manufacturing defects during the warranty period. Replacement parts you buy separately carry their own 90-day warranty, again excluding bags and brushes. Two conditions worth knowing before you file a claim: the warranty applies to original purchasers in North America only, and it’s void in pools with salt levels above 5,000 PPM — a detail salt-pool owners should confirm before assuming a Dolphin failure is covered.

Where to buy genuine Dolphin parts

Maytronics sells parts direct through its own official store (maytronics.com), and authorized dealers including InyoPools, PoolSupplyWorld, and Sunplay carry the same genuine part numbers. As the price-spread section above shows, neither channel is reliably cheaper — compare your specific part number at both before ordering. Avoid unbranded listings that don’t cite a Maytronics part number; Dolphin’s filtration and drivetrain parts are precision-fit, and a mismatched brush or track set won’t climb correctly.

The bottom line

On the Nautilus CC Plus, filters and brushes are routine, inexpensive maintenance — the ultra-fine cartridge kit at $82.99 and a standard brush at $43.99 are worth buying freely. On the Premier, match your filtration mode (cartridge vs. bag) before ordering. On the Liberty, the battery at $1,036.99 against a ~$999 new unit is the clearest “buy new” signal in Dolphin’s entire catalog. And on any model, check the identical part number at both Maytronics’ own store and an authorized dealer like InyoPools — the price can differ by well over $100 depending on the item.
