Spare parts for Hayward pool cleaners

Exact compatibility can be verified by identifying the reference printed on the chassis rating plate or checking the parts diagram number in the original Hayward manual.

• Suction-side cleaners: Models such as Navigator or Pool Vac use 1-meter sections of sealed hose and the AXV070 concave bevel gear for spiral movement.
• Electric robots: Ranges such as AquaShark and eVac require specific electronic components, sealed drive tracks, and the RCX26000 oscillating steering bearing.
• Additional filtration: To protect the suction system when there are too many branches, the Zodiac Cyclonic™ Leaf Catcher leaf pre-filter accessory is typically installed before the main inlet.

Comparing the part number engraved on the damaged component with the technical diagram helps prevent assembly errors and mechanical play.

Loss of traction and thrust in mechanical pool cleaners is usually caused by worn lower skid pads or play in the reduction gear.

First, check the thickness of the four support pads: if the wear indicator line has disappeared, the chassis scrapes against the bottom and slows down. Second, remove the bottom cover and inspect the teeth on the AXV070 bevel gear; if they are chipped, the turbine spins but does not transfer the rotational torque to the side flaps. If the mechanical components are intact, check the suction at the inlet using the main filter pressure gauge.

The drive tracks and cleaning rollers need replacing every 2 or 3 seasons, depending on the pool finish and chemical exposure.

In pools with à carrelage or porcelain tile, the rubber compound loses its grip after 400 cleaning cycles, causing the robot to slip when it starts climbing the walls. On liner or reinforced PVC surfaces, abrasion is lower, but chlorine buildup and thermal shock harden the elastomer. If you notice visible cracks, more than 1.5 centimeters of play around the guide pulleys, or a loss of vertical traction, replace both axles at the same time as a preventive measure.

A premature interruption of the operating cycle is almost always caused by an overload in the drive motor or extreme clogging of the filter panels.

• Clogged filter: Remove the fine-micron cartridges and clean them under pressure. When they build up limescale or microscopic algae, the flow collapses and the electronics cut off the power for safety.
• Drive shaft jammed: Check the bearings and drive pulleys for tangled hair or plastic fibers.
• Electrical seal: Check that the motor block O-ring forms a hermetic seal with no internal condensation.

Replacing the steering bearings or seals fixes the fault without having to discard the device.

Original components ensure millimeter-precise fit tolerances and specific chemical resistance to degradation from intensive chlorine treatments.

Non-certified aftermarket parts often have loose-fitting gears and are prone to premature deterioration with continuous exposure to disinfectant. To prevent misalignments that could compromise the pool's technical system, it's best to maintain official hydraulic compatibility, as when connecting a 6-Way 1½" Multiport Valve (SP0710X62E) to the filter assembly. Investing in factory replacement parts protects the appliance's technical warranty and prevents unexpected mechanical costs.

Air bubbles entering the circuit or sections accidentally disconnecting are caused by a conical coupling that is worn or hardened by ultraviolet radiation.

Suction-side pool cleaners rely on a completely airtight seal between intermediate hose sections measuring 1 to 1.2 meters, with male-female conical connections. When the ends lose their elasticity, the pump draws in air, suction flow decreases, and the internal turbine stops. Replace damaged sections and connect the suction adapter directly to the skimmer cone or cleaner connection to ensure a complete vacuum throughout the entire filtration cycle.

Before starting assembly, clean the plastic housings to remove any silica sand residue, and check the tightening torque without forcing the casings.

• Joint lubrication: Use silicone-based lubricant made specifically for pools on O-rings, avoiding petroleum products that cause rubber to swell.
• Shaft alignment: Position the RCX26000 steering bearing, checking for any axial wobble before closing the front cover.
• Dry run check: Manually turn the wheels and tracks to confirm smooth, even movement before submerging the device in water.

Proper assembly ensures that new components maintain their expected service life without premature wear.
