Automatic Pool Cleaner Replacement Parts & Accessories

Extend the life of your automatic pool cleaner with genuine and OEM-compatible replacement parts and accessories. PST Pool Supplies stocks a comprehensive range of pool cleaner components — hose sets, wheels, O-rings, control units, filter cartridges, and drive components — for Zodiac Polaris, Hayward, Maytronics Dolphin, Pentair, A&A Manufacturing, and Water Tech cleaners, with prices starting from $13.

Wear items like hoses, wheels, and O-rings are the most frequently replaced components on pressure-side and suction-side cleaners. The Zodiac Baracuda Wahoo hose kit, Polaris axle block screws, and O-ring kits for Zodiac Waterpik and Caretaker UltraFlex valves keep your cleaner moving and sealed correctly. For robotic cleaners, Maytronics Dolphin spring cartridge filter panels (set of 4) restore filtration efficiency when the existing panels are worn or clogged with fine debris. The Zodiac Polaris 9300 control unit is a direct electronic replacement for the robotic cleaner's drive and logic module — one of the most common repair items on the 9300 series. Pentair Sta-Rite GW9500 shaft kits, Hayward TigerShark restrictor plate kits, and A&A 5-port low-profile valve O-rings round out the selection for in-floor and robotic systems. For complete cleaner units, browse our pressure-side cleaner collection and robotic cleaner collection. Zodiac Polaris parts diagrams and exploded views are available at Zodiac's official parts support portal.

Identifying the correct replacement part requires your cleaner's exact model number — not just the brand. A Polaris 280 and a Polaris 380 share some parts but differ significantly in others; the same applies across Hayward TigerShark, SharkVac, and Navigator Pro models. The model number is typically printed on a label on the cleaner body or on the back of the power supply unit (for robotic cleaners). If you can see your cleaner's symptoms — e.g., one wheel not spinning, the cleaner drifting to one side, loss of suction, or poor wall climbing — contact our team with your model number and symptom description and we'll help identify the correct part before you order.

Shop pool cleaner replacement parts and keep your automatic cleaner running at peak performance season after season.

Frequently Asked Questions

How do I know which replacement parts fit my pool cleaner?
Start with your cleaner's exact model number — not just the brand. For Polaris cleaners, the model number (180, 280, 380, 9300, etc.) is printed on a label on the cleaner body. For Hayward cleaners (TigerShark, SharkVac, AquaNaut), the model is on the body label or on the back of the power supply. For Maytronics Dolphin robots, the model is on a sticker underneath the cleaner. Different models within the same brand often use different hose diameters, wheel assemblies, and drive components — so the model number is essential. Use it to search our parts catalog, or contact our team with the model and your symptom description and we'll identify the right part.
My pool cleaner isn't moving — what part is likely the problem?
If your pool cleaner isn't moving at all, the diagnosis differs by cleaner type. For a pressure-side cleaner (Polaris 280/380, Pentair Racer), check the booster pump first — if it's not running or has low pressure, the cleaner won't move. If water pressure is fine but the cleaner is stationary, check the drive train: worn wheels, stripped axle components, or a broken thrust jet are the most common causes. For a robotic cleaner (Dolphin, TigerShark), a non-moving unit usually points to the control unit or motor — check the power supply indicator lights first; if the unit powers on but doesn't move, the control unit (like the Zodiac Polaris 9300 control unit) is the likely failure point. For a suction-side cleaner, check for debris clogging the throat and ensure the main pump is running at adequate flow.
How often should I replace my robotic pool cleaner's filter cartridges?
For Maytronics Dolphin robots (and similar robotic cleaners), filter cartridge panels should be rinsed with a garden hose after every cleaning cycle. Inspect them every 3–5 cleaning cycles for damage, tears, or clogging that won't rinse out. Replace the cartridge set when the panels are torn, deformed, or no longer hold their shape — a deteriorated filter reduces suction and leaves debris behind in the pool. In a typical residential pool cleaned 2–3 times per week, cartridge panels generally last 1–2 seasons. Fine filter cartridges (for algae and fine particles) may need more frequent replacement than standard mesh panels. Always store your robot with clean, dry cartridges installed to prevent mold and deterioration during off-season storage.
What is the Caretaker UltraFlex valve and why might it need an O-ring replacement?
The Caretaker UltraFlex is an in-floor pool cleaning system — a network of pop-up nozzles built into the pool floor that rotate and sweep debris to the main drain. The system uses a distribution valve to sequence water pressure through different zones. Over time, the O-rings inside the valve body and lid assembly degrade from UV exposure, chemical exposure, and mechanical cycling, causing the valve to leak, lose pressure, or fail to rotate properly. Replacing the O-ring kit (available for both UltraFlex 1 and UltraFlex 2 valve generations) is significantly less expensive than replacing the entire valve. The Transformer Upgrade Kit allows older UltraFlex 1 systems to be upgraded to UltraFlex 2 valve compatibility. If you're unsure which generation you have, check the lid: UltraFlex 2 lids have a flat-top design; UltraFlex 1 lids are domed.
