DOLPHIN AVALON SERIES SPARE PARTS

Identifying the exact model using the serial number label on the robot’s lower casing determines whether a spare part is fully compatible. Pool cleaners in the Avalon range share chassis components, but vary depending on their equipment level:

• Avalon 20: uses a standard fine-filtration basket and a basic drive system with a single track.
• Avalon 30 and above: feature combined ultra-fine filtration panels, dual active brushing, and compatibility with a floating cable fitted with an anti-twist swivel.
• Drive system: the official Maytronics reference for the 9983152 track belt for the Avalon chassis fits across the entire series to restore grip on slopes.

Checking the technical exploded-view diagram helps avoid buying parts from incompatible generations.

Wear on the drive belts or PVC brushes often causes a loss of vertical traction in à carrelage or liner pools. When the tracks lose elasticity or their inner treads become smooth, the motor turns but the robot cannot grip firmly.

Visually inspecting the drive kit helps determine whether the belt is loose or cracked. Replacing a worn track with an original spare restores the grip needed to climb walls. If there is algae on the pool floor, it’s also worth checking the condition of the front active brush before installing new mechanical components.

You should replace the panels or basket when the mesh has visible tears, the plastic frame is deformed, or there is persistent limescale buildup. A damaged basket allows coarse debris to reach the suction impeller, risking a motor block blockage.

The 70-micron fine filters are used to collect larger debris in spring, while the 15-micron super-ultra-fine panels trap fine dust and sand during routine maintenance in 2026. Keeping both sets operational ensures effective cleaning throughout the swimming season.

Yes, the Avalon series monobloc basket has a modular frame compatible with the super-ultra-fine panels on higher-end models. The compatibility of the monobloc basket and SUF ultra-fine panels with the Avalon 20 and Avalon 30 lets you swap filtration frames without changing the pool cleaner’s structure.

This technical upgrade improves the retention of fine debris without straining the motor's suction flow. The replacement is done by fitting the four SUF panels into the slots on the existing holder in under two minutes, with no additional tools.

Rinsing the basket and bearings with running water after each cycle prevents chlorine and salt buildup from damaging the elastomers. The durability of replacement parts depends directly on the pool water's chemical balance:

• Remove the equipment from the water when applying chlorine shock treatments, and leave it out until neutral levels are restored.
• Clean the suction impeller regularly by unscrewing the top cover to remove any accumulated hair or fibers.
• Store the tracks and cables away from direct sunlight to prevent the rubber from losing flexibility over time.

Storing the equipment in the shade prevents premature deformation of the rollers and brushes.

Cable coiling is usually caused by a lack of tension in the floating cable or a fault in the swivel mechanism that releases cable twists. Over time, the buildup of dirt and scale in the swivel connector impedes the free rotation of the electrical wires.

Unwinding the cable on a flat surface in the sun for a few hours restores its linear memory. If the connector is cracked or the internal connection fails, replacing the original power cable is the only option to ensure a watertight seal and prevent the power supply from cutting off current due to overvoltage during scheduled cycles.

Check the condition of the front female connector and the response of the power button before attributing an electrical fault to the transformer. Modern power supplies have automatic short-circuit protection.

The specific adjustment of the anti-tangle swivel cable on Avalon range power supplies requires a secure threaded connection to prevent moisture ingress. If the LED indicator flashes red or fails to provide a continuous voltage output after startup, the electronic module must be replaced with a certified Maytronics unit to restore the robot's maneuverability in 2026.
