Maytronics Dolphin DYN 18m cable for Nauty TC, Swash CL/TC, Star (Plus), Mybot and Acapoolco TC - 9995853-DIY

Maytronics Dolphin DYN 18m cable for Nauty TC, Swash CL/TC, Star (Plus), Mybot and Acapoolco TC

This is the genuine OEM 18-metre DYN (3-wire, dynamic) replacement cable for the Maytronics Dolphin entry-level robotic pool cleaners in the Nauty/Swash/Star/Mybot/Acapoolco family. It carries both power and the third communication line required by these robots, connecting the power supply to the drive and motor unit inside the cleaner body. The -DIY suffix means it ships with a pre-moulded motor-end connector, making it a direct plug-in replacement for the original -ASSY cable.

What this cable does in the Dolphin

The DYN designation confirms a 3-conductor construction: two conductors deliver DC power to the drive motor, and the third wire handles dynamic communication signals between the power supply and the cleaner’s onboard electronics. Losing integrity on any of these conductors — through a crush, kink, UV degradation, or a damaged connector — causes intermittent stoppages, error codes, or complete loss of robot function. This cable restores full electrical continuity across all three lines.

Which Dolphin models it fits

This cable is confirmed for the Dolphin Nauty TC, Swash CL, Swash TC, Star, Star Plus, Mybot, and Acapoolco TC. It is also listed against the Dolphin Master M5 parts schema (reference 9995853-DIY) as a cross-compatible part. Always cross-reference with the exploded-parts diagram for your specific robot serial number before ordering, as connector variants differ between production runs.

Signs it needs replacing

Inspect the full cable length for visible kinks, cuts, or sections where the outer jacket has split or whitened from UV exposure. A robot that cuts out mid-cycle, fails to start despite a functioning power supply, or throws a communication fault is frequently traced to a degraded third wire in a DYN cable. Visible corrosion or a cracked housing on the motor-end connector is an immediate replacement trigger — a poor connection here causes arcing and risks damaging the motor unit.

How to install it

The -DIY connector is pre-moulded onto the motor end, so no soldering or crimping is required. Open the cleaner’s top panel, unplug the failed cable’s connector from the motor block, thread the new cable through the cable entry and seat the moulded plug until it clicks. Feed the opposite end to the power supply and clip the cable tidy back into place. The complete swap takes around 15 minutes with a Phillips screwdriver and does not require specialist tools.

Warum Originalprodukte von Maytronics wichtig sind

Dolphin power supplies and motor units are calibrated to the precise electrical characteristics of OEM cables — conductor gauge, insulation rating, and connector seating depth are all matched at manufacture. Aftermarket cables with incorrect wire gauges or ill-fitting connectors introduce resistance variations that can trigger nuisance fault codes or, over time, stress the PSU output stage. The genuine Maytronics part guarantees the connector seats correctly inside the motor unit first time.
