Product Description

The Zodiac AX20 Gearbox Side A is an essential replacement part for keeping your Zodiac AX20 automatic pool cleaner moving correctly around the pool. The gearbox forms part of the cleaner’s steering system and helps manage directional changes as the cleaner moves across the floor, walls and pool surface areas that the AX20 is designed to clean.

Over time, the gearbox can wear due to normal use, especially in South African pools where dust, leaves, fine debris and regular seasonal use can place extra strain on pool cleaner parts. A worn gearbox may cause the cleaner to move unevenly, turn incorrectly, get stuck more often or lose part of its normal cleaning pattern.

The Zodiac AX20 cleaner uses two gearboxes, namely Gearbox Side A and Gearbox Side B. These two parts work together to support balanced steering and reliable directional movement. For this reason, replacing both gearbox sides at the same time is recommended when one side shows wear. This helps prevent one new part from working against an older worn part.

This product includes Gearbox Side A only. It is a genuine Zodiac replacement part made specifically for the AX20 cleaner, giving pool owners a practical way to restore correct movement without replacing the full cleaner.

FAQs

What is the Zodiac AX20 Gearbox Side A used for?

The Zodiac AX20 Gearbox Side A is part of the cleaner’s internal steering and movement system. It helps the cleaner change direction and follow its normal movement pattern inside the pool. When the gearbox is working correctly, the cleaner can move more consistently and cover the pool more effectively.

How do I know if my AX20 gearbox may need replacement?

Common signs include the cleaner turning poorly, moving in circles, getting stuck in the same areas, moving unevenly or not following its normal cleaning pattern. If the cleaner has lost steering control but the hoses, diaphragm and other wear parts are in good condition, the gearbox may need inspection.

Does the gearbox improve suction?

The gearbox does not create suction. Suction comes from the pool pump and cleaner system. However, a working gearbox helps the cleaner use that suction more effectively by moving and steering correctly through the pool.

Does this part help with wall climbing?

The gearbox supports movement and steering, which can influence how well the cleaner follows its intended cleaning path. Wall climbing can also depend on pump suction, hose condition, flow setting, pool surface, cleaner setup and other wear parts.

Should I replace both AX20 gearboxes at the same time?

Yes, this is recommended. Since Gearbox A and Gearbox B work together, replacing only one side may leave the cleaner with uneven wear between the two sides. Replacing both can help restore more balanced operation.

Is this part suitable for all pool surfaces?

This gearbox is an internal replacement part for the Zodiac AX20 cleaner. It is not surface specific. Suitability depends on whether the Zodiac AX20 cleaner itself is suitable for your pool surface.

Is this a genuine Zodiac replacement part?

Yes. Based on the supplied product information, this is a genuine Zodiac part designed for the Zodiac AX20 pool cleaner.
