Zodiac Vortex 3-4 4WD

Zodiac Vortex 3 / Vortex 4 4WD exploded view & spare parts

This exploded-view diagram covers genuine spare parts for the Zodiac Vortex 3 4WD and Vortex 4 4WD robotic pool cleaners, sold under factory references W9347 and W9446. Whether your robot carries one reference or the other, you are in exactly the right place — both variants share the same part architecture and are fully covered by this diagram. Every numbered position on the diagram maps to an exact genuine Zodiac part listed below, so you can identify what you need with confidence and order only the correct component for your machine. All parts stocked on poolparthub.com are authentic Zodiac items, ensuring a perfect fit and preserving your robot’s warranty and performance.

How to use the numbered diagram to find your part

Start by identifying the area of your Vortex 3/4 4WD that needs attention — whether that is the drive train, the filtration section, the brush assembly or the outer casing. Each component in the illustration carries a unique position number that corresponds directly to a part listing on this page. Cross-reference the number with the part name and description, confirm your factory reference (W9347 or W9446 — both are valid here), then add the correct item to your basket. If you are unsure which part has failed, the diagram is especially useful for tracing the path of a symptom: reduced suction points to the filter or suction propeller area, a robot that veers to one side often indicates a worn pinion gear or wheel assembly, and a machine that will not move at all may point to the motor block section.

Main replaceable parts covered by this diagram

The diagram covers every major serviceable assembly of the Vortex 3/4 4WD. In the drive train you will find the large black wheel rims, large tyres (RAL9022), the 17-tooth and 27-tooth pinion gears (each sold as a pack of two), wheel bearing bushings, and exterior bushings — everything needed to restore confident four-wheel-drive traction. The brush and roller system is represented by the short PVC brushes (sold in pairs), the brush holder rollers (pack of two), and the roller support. Filtration options include the standard 100-micron replacement filter compatible with Vortex/OV/RV models, the Alpha iQ fine 100-micron filter, the 200-micron large-debris filter, the mesh protection, the filter canister support, and the flow channeler. For power and propulsion, the suction propeller (impeller), motor block type C, and motor block type D (also compatible with Polaris 9550 and 9650iQ Sport) are all listed. The floating cable section covers the 21-metre floating cable without swivel as well as a general floating cable replacement. Outer bodywork parts include the main housing top and bottom, the upper front cover (blue deco), the hood blue spoiler, the Vortex bumper with wheels (pair), and the handle kit for the 9400 Sport. Finally, the hardware kit selection — Vortex screws in 2.9 × 9.5 mm, 4 × 12 mm, and 4 × 25 mm variants, 4 × 16 mm screws, and 3 × 16 mm fixing clips, all supplied in convenient packs of five — means you will never be short of the small fasteners that hold every assembly together.

Common wear items and when to replace them

Certain parts on the Vortex 3/4 4WD experience regular wear and should be inspected at the start and end of every pool season. PVC brushes are the first thing to check: once the bristles are visibly worn down, shortened, or no longer making full contact with the pool floor, cleaning quality drops noticeably and they should be swapped out. Pinion gears (17-tooth and 27-tooth) and tyres wear gradually through continuous contact with pool surfaces; if you notice the robot slipping, losing grip on walls, or leaving unswept tracks, inspect these components first. Filters degrade over time even with regular rinsing — the mesh can develop micro-tears that allow fine particles to pass through — so replacing the filter panel once a season, or sooner in heavily used pools, keeps suction at full power. The floating cable is exposed to UV, chemicals, and constant flexing; cracks in the outer sheath or swivel stiffness are the signal to fit a replacement before an electrical fault develops. Wheel bearings and bushings are small but critical: grinding or irregular movement in the wheels usually means these are due for renewal. Keeping a small stock of the assorted screw and clip packs is also sensible, as these fasteners are easy to lose during routine maintenance strip-downs.

Why genuine Zodiac parts make the difference

The Zodiac Vortex 3 and Vortex 4 4WD are precision-engineered machines, and their performance depends on components that meet tight tolerances — particularly in the motor block, gearbox, and filtration system. Genuine Zodiac spare parts are manufactured to the same specifications as the original production parts, which means correct fit, correct materials, and correct filtration ratings (100 µm or 200 µm as designed). Aftermarket alternatives may appear similar but often use softer plastics for brushes and tyres, less durable mesh for filter panels, and motors that do not match the original current draw — all of which can shorten the life of surrounding components. Using genuine parts also ensures that your robot continues to operate within the parameters Zodiac’s engineers designed for, protecting the motor block and power supply from stress caused by mismatched components. Every part on this page is an authentic Zodiac item supplied through an authorised channel, so you can order with complete confidence.

Ordering tips and compatibility notes

This diagram and all parts listed apply to both factory references W9347 (Vortex 3 4WD) and W9446 (Vortex 4 4WD) — if your robot carries either of these codes on its label, every part on this page is compatible with your machine. When ordering filters, consider keeping one 100-micron fine filter for normal use and one 200-micron large-debris filter for the first clean of the season or after heavy storms when leaf and twig load is high. If you are replacing the motor block, note that type C and type D variants are listed separately — check your existing motor block label before ordering. For hardware, the screw and clip packs are sold in sets of five, which is ideal for a full service where you replace all fasteners in a given assembly at once rather than reusing aged hardware.
