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.
This motor delivers high rotational speed and powerful suction, which translates to thorough debris removal from pool floors and walls.

Buying Guide: Choosing the Right Dolphin Motor Unit
Compatibility with Your Dolphin Model
Not all Dolphin motor units fit every cleaner. Each part number is designed for a specific set of models. For example, the 9995389-EX fits the S50, Active 10, T15, and several others, while the 99953031-EX works with the DX3, Supreme M3, and Atlantis. Always cross-reference your cleaner’s model number with the product’s compatibility list before purchasing.
If you own a Dolphin Premier or Triton, the 9995372RD-EX from Bzcovac is a compatible alternative that can save you money. For the most common Dolphin models, the top robotic pool cleaner motor units page offers a broader selection.
Genuine Maytronics Parts vs. Compatible Replacements
Genuine Dolphin motor units (sold under the Maytronics brand) are certified to meet original specifications. They offer guaranteed fit and performance, backed by a warranty. The 9995389-EX, 99953010-EX, and 99953031-EX are all genuine parts. They tend to cost more but provide peace of mind.
Compatible motor units like the Bzcovac 9995372RD-EX are manufactured to OE specifications and often come at a lower price. They include a 1-year warranty and 30-day return policy. For budget-conscious owners, these are a solid choice. Our pool cleaner replacement motor guide compares genuine and aftermarket options in more detail.
Performance and Durability
A motor unit’s rotational speed and torque determine how effectively the cleaner climbs walls and picks up debris. Genuine Dolphin parts are engineered for long life in harsh pool chemicals. The 9995388-EX, for instance, powers high-end models like the Active 30i and S300i, delivering consistent suction across large pools.
Compatible units are built to similar standards but may have slightly different duty cycles. For heavy daily use, a genuine part is often the better investment. If you are upgrading or repairing an older unit, check our robotic pool cleaner drive motor article for related components.
Warranty and Return Policy
Genuine Maytronics parts come with a standard manufacturer warranty, though the length varies by seller. Compatible brands like Bzcovac offer a 1-year warranty and 30-day returns. Always check the warranty before buying, especially for higher-priced units. For a list of all replacement parts, visit the Replacement Parts category.
Final Thoughts
When your Dolphin pool cleaner needs a new motor unit, the right choice depends on your model and budget. For owners of the S50 or Active 10 series, the Dolphin Genuine Replacement Part offers certified performance and a perfect fit.
