Maytronics Dolphin Cable Blue 18m 2-Pin Swivel (99958907-DIY) – X30, S200, S300i, DB1, Kbot SX-B, Prowler 920

Genuine Maytronics Dolphin Cable — Blue 18m 2-Pin Swivel, part no. 99958907-DIY. This is the OEM replacement power and communication cable for a range of Maytronics Dolphin robotic pool cleaners. The 18-metre length suits most residential pools, and the swivel connector at the cleaner end prevents cable tangling during operation.

A damaged, kinked, or water-ingressed cable is one of the most common causes of Dolphin cleaner failure. Replacing with a genuine Maytronics cable restores full power delivery and communication between the cleaner and its power supply unit (PSU).

Frequently Asked Questions

How do I know if my Dolphin cable needs replacing?

Common signs of a failing Dolphin cable include the cleaner stopping mid-cycle, error codes on the power supply unit, visible cuts, kinks, or cracking in the cable jacket, water ingress at the connector, or the cleaner not powering on at all. Inspect the full length of the cable and both connectors for damage.

What does the swivel connector do?

The swivel connector at the cleaner end of the cable rotates freely as the Dolphin moves around the pool. This prevents the cable from twisting and tangling during the cleaning cycle, which extends cable life and ensures the cleaner can navigate the pool without restriction.

Is 18m long enough for my pool?

An 18m cable suits most residential pools up to approximately 12–14 metres in length. The cable runs from the power supply unit (PSU) at the pool edge down to the cleaner on the pool floor, so the effective reach is less than the full cable length. If your pool is larger or the PSU is positioned further away, contact us to discuss options.
