Astralpool Xtreme robotic pool cleaner replacement nozzle - 3386WT

Astralpool Xtreme robotic pool cleaner replacement nozzle

This is the genuine OEM suction nozzle for the Astralpool Xtreme robotic pool cleaner. Positioned at the base of the robot’s intake throat, the nozzle forms the critical aperture through which debris-laden water is drawn up into the filtration chamber, directly governing the suction footprint and particle-capture efficiency of every cleaning cycle.

How the nozzle controls suction performance

The nozzle acts as the primary flow-restriction point between the pool floor and the robot’s internal hydraulics. Retracting or lowering the nozzle height shifts the velocity profile of incoming water, allowing the operator to optimise pick-up for fine particles such as dust and pollen at one setting, or heavier debris such as sand and grit at another. Any deformation, cracking or wear to the nozzle body disrupts this balance and causes a measurable drop in suction pressure across the head.

Compatibility with the Xtreme range

This nozzle is a genuine Astralpool spare part sourced specifically for the Xtreme series robotic cleaner. Always cross-reference your robot’s model label before ordering, as nozzle geometry is model-specific and an incorrect fit will compromise both suction seal and floor contact.

Signs that the nozzle needs replacing

Replace the nozzle immediately if you observe any of the following: visible cracks or chips on the nozzle lips; reduced or uneven suction at the intake port; debris bypassing the intake and remaining on the pool floor after a completed cycle; or audible changes in the robot’s water-flow tone that cannot be attributed to a blocked filter bag. A damaged nozzle is frequently the root cause of apparent motor-strain symptoms, because the pump overworks to compensate for lost head pressure.

Why genuine Astralpool parts matter

Third-party nozzles may differ in lip profile, wall thickness or material shore-hardness, all of which alter the sealing geometry against the pool surface and the internal duct. A genuine Astralpool replacement maintains the designed hydraulic cross-section, preserving the flow rate and suction consistency that the Xtreme’s motor and filter system were calibrated to handle. It also ensures the part seats correctly within the robot’s chassis without stress-loading adjacent clips or brackets.
