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
Compatibility: Match the Motor to Your Model
Not all motors fit every robot. Dolphin, for example, uses different part numbers for different series. The Dolphin Genuine Replacement Part (9995389-EX) works with S50, Active 10, T15, and others, while the 9995372RD-EX Motor Unit from Bzcovac fits older Dolphin models like Advantage Plus and Premier. Always verify your robot’s model number before ordering. Betta skimmers have their own rotor and propeller sets, so check compatibility with Betta Flex, SE Plus, or SE (not Betta 2).
If you’re also replacing wheels, see our guide on dolphin nautilus replacement wheels for compatible options.
Power and Performance: Suction and Speed Matter
A replacement motor should restore your cleaner’s original suction and mobility. Look for motors with high rotational speed and efficient debris removal. The Dolphin Genuine Replacement Part (99953031-EX) delivers reliable power for DX3 and Atlantis models. Betta’s genuine rotor and propeller set ensures smooth skimming on the water surface. For high-performance cleaning, the Dolphin Genuine Replacement Part (9995388-EX) supports premium units like Active 30i and Quantum.

Durability: Built to Last in Harsh Pool Conditions
Pool chemicals, debris, and constant water exposure demand a robust motor. Genuine Dolphin parts are certified by Maytronics and designed for long life. The Bzcovac motor is manufactured to OE specifications and includes a one-year warranty. Betta’s rotor set is made from durable materials to handle daily skimming. Avoid cheap knockoffs that may fail quickly.
Wheel replacements also affect longevity. Check our dolphin wheel replacement kit for compatible upgrades.
Ease of Installation: DIY or Professional Help
Most replacement motors are designed for straightforward installation. Dolphin motor units typically require removing a few screws and unplugging the old motor. Betta’s rotor and propeller set is a direct swap. If you’re comfortable with basic tools, you can do it yourself. Otherwise, a pool service professional can handle it quickly.
Final Thoughts
Choosing the right pool robot replacement motor depends on your cleaner’s model and your needs. For broad compatibility and trusted quality, the Dolphin Genuine Replacement Part is a solid choice for many Dolphin owners. If you have a Betta skimmer, the Betta Genuine Robotic Pool Skimmer Motor Rotor offers an affordable, genuine fix.

Can I replace the motor myself?
Yes, most replacement motors are designed for DIY installation. You need a screwdriver and basic mechanical skills. Follow the manufacturer’s instructions or watch online tutorials. For complex models, consider professional help.
How long does a replacement motor last?
With proper care, a genuine replacement motor can last 2 to 4 years, depending on usage and pool conditions. Regular cleaning of filters and checking for debris extends motor life. For tips on maintaining other parts, see our Betta category page.
