Maytronics 9995386-EX Motor Unit (S1 Climb) for Dolphin Robotic Pool Cleaners | Genuine Replacement

The Maytronics 9995386-EX is a genuine Dolphin replacement motor unit, commonly listed as Motor Unit, S1 Climb, EX. It is designed for select Maytronics Dolphin robotic pool cleaners and is used to restore normal cleaner movement and wall-climbing performance when the original motor unit fails or becomes unreliable.

Key Features

  • Part number: 9995386-EX
  • Brand: Maytronics (Dolphin genuine part)
  • Product type: Replacement motor unit
  • Common description: Motor Unit, S1 Climb, EX
  • OEM replacement component for compatible Dolphin robotic pool cleaners
  • Commonly listed warranty: 1 year (listing/manufacturer dependent)
  • Commonly sold as an exchange-style replacement unit (often marked “EXCHANGE” on label)

What This Part Does

  • Replaces a worn, damaged, or failed motor unit in compatible Dolphin cleaners
  • Helps restore drive and wall-climbing operation on climb-capable models
  • Supports continued use of the cleaner without replacing the entire robot
  • Maintains OEM fit and function when matched to the correct cleaner model

Common Compatibility Notes (Verify Before Ordering)

  • Used on select Dolphin S1 Climb / active-climb style cleaner platforms
  • Retailer listings commonly reference fitment for models such as Dolphin Nautilus CC, S100, and some related variants (model/version dependent)
  • Some listings also reference compatibility with certain branded equivalents and legacy versions
  • Always verify your exact cleaner model and existing motor unit part number before ordering

Important Notes

  • This is commonly identified as an S1 Climb motor unit; confirm it matches your cleaner configuration.
  • “EX” / “EXCHANGE” labeling on the unit is commonly used for replacement parts and does not necessarily indicate a refurbished unit.
  • Motor units are often non-returnable once installed, so fitment confirmation is important before opening/installation.
  • If your cleaner has other issues (power supply, cable, tracks, filters), inspect those components before replacing the motor unit.

Installation Notes

  • Disconnect the cleaner from the power supply before servicing.
  • Follow the manufacturer service procedure for your exact Dolphin model.
  • Inspect seals, cable connections, impeller area, and internal components while replacing the motor unit.
  • Test floor movement and wall-climbing performance after installation.
  • If unsure, use a qualified pool equipment service technician for installation.

Maintenance Tips

  • Rinse the cleaner after use and keep filters clean to reduce strain on internal components.
  • Inspect the floating cable and connectors regularly for wear or damage.
  • Remove debris from tracks/rollers and intake areas to help maintain smooth operation.
  • Store the cleaner out of direct sun when not in use to help extend component life.
  • Address performance issues early to prevent extra wear on the motor unit and drive system.
