Zodiac Vortex 2, 3 & 4

Zodiac Vortex 2, Vortex 3 & Vortex 4 exploded view & spare parts

This single exploded-view diagram covers the complete Zodiac Vortex range — including the Vortex 2 (W9104), Vortex 3 (W9330) and Vortex 4 (W9440). If your robot carries any one of those factory references, you are in exactly the right place. The diagram maps every numbered component to a genuine Zodiac spare part, so whether you need a small fixing clip, a full body shell or a replacement floating cable, you can identify and order the correct item in minutes. All parts listed on this page are genuine Zodiac Vortex spares, supplied in the original factory packaging and fully compatible across the W9104, W9330 and W9440 references.

How to use the numbered diagram to find your part

Each component in the illustration carries a reference number that corresponds directly to a line in the parts list below the diagram. Start by identifying the area of the robot that needs attention — for example the drive train, the filter basket or the brush assembly — then locate that zone in the drawing and note the number shown. Match that number to the parts list to confirm the full part name, pack size and SKU before adding it to your basket. If a part appears in more than one location on the robot (such as the 2.9 × 9.5 mm screws used throughout the chassis, or the brush-holder rollers fitted at both ends of the cleaning head), the diagram will show the same number in each position, so you only need to order one line item. For fastener sets — screws in 4 × 16 mm, 4 × 12 mm and 4 × 25 mm formats, as well as the 3 × 16 mm fixing clips — the diagram clearly distinguishes which screw type sits in which location, avoiding the easy mistake of ordering the wrong pitch or length.

Main replaceable assemblies on the Vortex 2, 3 and 4

The Zodiac Vortex range is built around a modular architecture, and the diagram reflects that by grouping parts into logical sub-assemblies. The drive system includes the 17-tooth and 27-tooth pinions (each sold as a pack of two), the wheel bearing bushings, the exterior bushings, and the full wheel assemblies — front large wheel rim with its large black cover or tile-grip suction-cup tyre, and the small rear wheel rim with its black rear cover. The cleaning head consists of the short PVC brushes (2 pcs.), the rubber brushes (pack of 2), the brush-holder rollers (pack of 2) and the roller support. The filtration group covers the suction propeller, the mesh protection, the filter canister support, and a choice of filter cartridges — the standard 100-micron fine filter, the Alpha iQ fine 100-micron replacement, the 200-micron large-debris filter, and the general Vortex / OV / RV replacement filter. Finally, the flow and buoyancy group includes the flow channeler, the front and rear float kit, the full body shell and the upper front frame.

Common wear items and when to replace them

With regular use, certain parts wear faster than others and are worth checking at the start and end of each pool season. The rubber and PVC brushes are the first point of contact with pool surfaces; once the bristles are visibly shortened, splayed or torn, cleaning performance drops noticeably and the brush-holder rollers can begin to wear unevenly — replace the brushes and inspect the rollers at the same time. Filter cartridges should be rinsed after every session and replaced when rinsing no longer restores suction; a clogged 100-micron fine filter causes the motor to work harder, shortening its lifespan. The drive pinions and wheel covers are subject to continuous friction; cracking, chipping or visible tooth wear on the 17- or 27-tooth pinions will cause the robot to veer or lose traction, particularly on walls. Floating cables — available in 15 m grey or 21 m without swivel — should be inspected for kinks, cracking of the outer sheath or damaged connectors; a compromised cable is both a safety concern and a source of erratic robot behaviour. The suction propeller and mesh protection should also be checked for chips or deformation, as even minor damage reduces cyclone suction efficiency.

Why genuine Zodiac parts matter for your Vortex robot

Zodiac engineers the Vortex range around tight dimensional tolerances — the pinion gear teeth, bearing bushing diameters, brush-roller fitments and filter-canister seals are all designed to work together as a system. Using genuine Zodiac spare parts ensures that clearances remain within specification, so the cyclone suction that makes the Vortex effective on floors, walls and the waterline is not compromised by an ill-fitting aftermarket component. Genuine parts also protect your warranty: fitting non-OEM components can void cover under Zodiac’s terms. Every item on this page — from the smallest 2.9 × 9.5 mm screw to the full body shell — is sourced directly through official Zodiac supply channels and sold by poolparthub.com with the original part number, giving you full traceability and the confidence that the part will fit first time.

Ordering tips and compatible models

All parts on this page are compatible with the Zodiac Vortex 2 (W9104), Vortex 3 (W9330) and Vortex 4 (W9440). Many consumables — brushes, filter cartridges and floating cable replacements — are also cross-compatible with other robots in the Zodiac OV and RV families, as noted in the individual product titles. When ordering fasteners, always check the diagram carefully: the Vortex uses at least four distinct screw formats (2.9 × 9.5 mm, 4 × 12 mm, 4 × 16 mm and 4 × 25 mm) plus the 3 × 16 mm fixing clip, and mixing them up during reassembly can strip threads or leave panels insecure. If you are unsure which cable length is right for your installation, measure the distance from your pool’s power supply socket to the furthest point of the pool and add a metre of slack — the 15 m cable suits most standard residential pools, while the 21 m option is recommended for larger or irregularly shaped pools.
