DOLPHIN C SERIES SPARE PARTS

Friction and filtration wear components in Maytronics robots require regular inspection to prevent reduced performance:

• Drive tracks: replace them when they lose tension or develop visible grooves that reduce grip on slopes.
• Active brushes and foam rings: replace them if the synthetic material becomes flattened or loses its grip on tile.
• Filter bags or panels: replace them if they develop microcracks that allow fine particles to flow back into the water.
• Bearings and drive rollers: replace them if there is play in the rotating shafts.

Inspecting these components every season ensures even cleaning of the floor and protects the internal mechanical components.

Slipping on vertical walls is usually caused by combined wear on the drive tracks or the brushes mounted on the transverse rollers.

On smooth tiled or porcelain surfaces, traction depends critically on the condition of the foam rings fitted to the combination brushes; if these rings are clogged with limescale or compressed, the robot loses hydraulic lift as it climbs. If the tracks are too loose, power from the motor unit is not transferred efficiently to the drive shaft. Replacing these components immediately restores mechanical grip on the pool’s steepest areas.

The fabric bag offers a large capacity for dense debris, while the cartridge panels maximize the retention of fine microparticles.

Standard filter bags are ideal during pool openings or periods of heavy leaf fall, thanks to their greater capacity and ease of shaking out. In contrast, ultra-fine pleated resin cartridges trap microscopic debris such as pollen, dust, or limescale sediment, providing superior water clarity during regular cycles. Maytronics designed compatible baskets that allow you to switch between the two systems according to the maintenance stage.

Permanent coiling is resolved by replacing the entire floating cable if the integrated swivel has internal contact damage or an irreversible mechanical jam.

The rotating swivel device is designed to rotate continuously through 360 degrees while transmitting the electrical current signal from the digital power supply to the motor assembly. With prolonged use, limescale ingress or wear on the internal conductive tracks can prevent it from rotating freely. When this happens, Dolphin C Series spare parts include the sealed cable section with preassembled watertight connections to prevent leaks directly into the power compartment.

A manual inspection makes it easy to distinguish an obstruction in the upper impeller from an electrical fault in the sealed motor:

• Physical check: With the equipment switched off, turn the impeller blade by hand. If branches or hair are blocking the passage, remove them without disassembling the motor.
• Power supply diagnosis: If the digital transformer shuts off after a few seconds, this usually indicates a safety lockout caused by excessive resistance in the drive system.
• Watertightness: If the impeller spins freely but the robot does not generate vertical water thrust, the motor’s internal winding needs to be replaced by a technician.

A regular preventive maintenance protocol doubles the operational life of commercial pool cleaners subjected to continuous disinfection cycles.

Rinse textile filters or cartridges under running water after each cycle to prevent chlorine from degrading the seams. Store the equipment in the shade to keep sunlight from drying out the rubber tracks or weakening the floating cable. Also, clean the roller bearings regularly to remove accumulated hair before it causes axial friction against the main drive motor.

Original Maytronics components ensure full dimensional compatibility with C Series chassis, preserving factory watertightness tolerances.

Using genuine spare parts prevents abnormal power consumption from the power supply and eliminates unusual vibrations in the drive tracks. Under the commercial framework in effect in 2026, each replacement part comes with official coverage against manufacturing defects. Checking the serial number on the bottom of the pool cleaner ensures you choose the exact part number required for each equipment variant.
