The Bzcovac 9995372RD-EX Motor Unit is a direct replacement motor designed for several older Dolphin robotic pool cleaners, including the Premier, Advantage Plus, and Deluxe 4. If your pool cleaner has lost suction or fails to move effectively, this motor unit can restore its original cleaning power without the cost of a new machine.

Buying Guide: Choosing the Right Motor Unit
Selecting the correct replacement motor unit is crucial for restoring your pool cleaner’s performance. Here are the key factors to consider before making a purchase.
Compatibility with Your Cleaner Model
The most important step is verifying that the motor unit fits your specific robotic pool cleaner model. Dolphin and other brands use different motor units for different model lines, and installing the wrong one can damage your cleaner or simply not work.
Always cross-reference the part number with your cleaner’s model number. For example, the Dolphin Genuine Replacement Part (9995389-EX) is compatible with S50, Active 10, T15, and others. If you’re unsure, consult your owner’s manual or contact the manufacturer.

Genuine vs. Compatible Parts
You’ll find both genuine OEM parts (like Dolphin Genuine Replacement Parts) and aftermarket compatible options (like Bzcovac). Genuine parts are designed to meet original specifications, ensuring a perfect fit and reliable performance. Compatible parts may offer a lower price but can vary in quality and longevity.
For most users, we recommend genuine Dolphin parts for peace of mind. However, if you’re on a budget, a well-reviewed compatible part like the Bzcovac 9995372RD-EX can be a viable option, especially if it comes with a warranty.
Motor Performance and Durability
Consider the motor’s power and duty cycle. A motor with high rotational speed will clean more effectively, especially on pool floors and walls. Also, check the duty cycle rating; some motors are designed for short-time duty, which is typical for robotic cleaners that run for a few hours per cycle.
Durability is equally important. Look for motors built to withstand harsh pool chemicals and debris. Genuine parts are often manufactured to OE specifications for enhanced longevity, as noted in the Bzcovac product description.

For most Dolphin owners, the Dolphin Genuine Replacement Part offers a perfect balance of compatibility and reliability, while the 9995372RD-EX Motor Unit for Dolphin Premier Pool is a solid budget-friendly alternative for older models. Whichever you choose, ensure it matches your cleaner’s model to enjoy a sparkling clean pool all season long.
