Product Description

The Zodiac AX20 Gearbox Side B is an important replacement part for keeping your Zodiac AX20 pool cleaner moving and steering correctly. The gearbox forms part of the cleaner’s internal steering system, helping it turn, change direction and follow its intended cleaning path around the pool.

Over time, pool cleaner gearboxes can wear from normal use. This is especially common in South African pools where dust, leaves, fine debris and long summer cleaning cycles can place extra load on moving parts. When the gearbox starts to wear, the cleaner may begin to turn poorly, move unevenly, get stuck in one area or miss sections of the pool.

The Zodiac AX20 uses two gearboxes, namely Gearbox Side A and Gearbox Side B. These two parts work together to control directional movement and steering accuracy. For this reason, it is recommended to replace both sides at the same time when one gearbox shows signs of wear. This helps prevent one new gearbox from working against an older worn gearbox.

This product includes Gearbox Side B only. It is a genuine Zodiac replacement part made specifically for the AX20 cleaner, making it a practical choice for pool owners, pool shops and service technicians who want to restore cleaner movement without replacing the full unit.

FAQs

What does the Zodiac AX20 Gearbox Side B do?

The Zodiac AX20 Gearbox Side B helps control the cleaner’s steering and directional changes. It works with Gearbox Side A to guide the cleaner’s movement pattern so it can travel through the pool more consistently.

How do I know if my AX20 Gearbox Side B may need replacement?

Common signs include poor turning, uneven movement, the cleaner getting stuck often, moving in circles or not following its normal cleaning pattern. If suction, hoses and other wear parts are still in good condition, the gearbox should be checked.

Does this gearbox improve suction?

No. The gearbox does not create suction. Suction comes from the pool pump and the cleaner’s hydraulic setup. However, a working gearbox helps the cleaner use available suction properly by allowing it to move and steer correctly.

Can this part help with cleaning coverage?

Yes, if the old gearbox is worn. A working gearbox helps the AX20 follow its designed movement pattern, which can support better pool coverage. Cleaning coverage also depends on suction flow, hose setup, cleaner condition and pool layout.

Does this part help with wall climbing?

The gearbox supports steering and movement, which can affect how the cleaner follows its path. Wall climbing also depends on suction strength, hose condition, flow setting, pool surface, cleaner setup and other wear parts.

Should Gearbox Side A and Gearbox Side B be replaced together?

Yes, it is recommended. The two gearboxes work together, so replacing both at the same time helps avoid uneven wear and supports more balanced cleaner movement.

Is this part suitable for all pool surfaces?

The gearbox itself is not pool surface specific. It is an internal replacement part for the Zodiac AX20 cleaner. Pool surface compatibility depends on whether the 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 replacement part designed for the Zodiac AX20 pool cleaner.
