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. It operates on a short-time duty cycle, meaning it is built for intense cleaning sessions but not continuous all-day use. For most residential pools, this is perfectly adequate.
Manufactured to original equipment specifications, the motor promises a precise fit and long-term durability against pool chemicals and wear. The black casing is robust and designed to withstand the harsh pool environment, giving you confidence in its lifespan.
One potential drawback is the lack of user reviews, so real-world performance is unverified.

Buying Guide for Pool Robot Motor Units
Compatibility with Your Cleaner Model
The most critical factor is ensuring the motor unit fits your specific pool robot. Dolphin models use different motor part numbers for different series: the 9995389-EX works with S50, Active 10, and T15, while the 99953031-EX fits DX3, Supreme M3, and Atlantis. The Betta rotor set is only for Betta Flex, SE Plus, and SE, not the Betta 2. Double-check your cleaner’s model number against the product description. If you have a Dolphin Nautilus, you might also need dolphin nautilus replacement wheels to keep everything rolling smoothly.
Motor Performance and Suction Power
A replacement motor must deliver the same or better rotational speed and torque as the original. The Bzcovac 9995372RD-EX, for instance, is described as having high rotational speed for thorough cleaning. Genuine Dolphin motors like the 9995386-EX restore full suction to models like S100 and Active 15. If your robot struggles with debris on walls or floor, a motor with consistent power output will make a difference. For above-ground pools, heavier debris may require a stronger motor; check our above-ground pool cleaners guide for compatible robots.
Durability and Build Quality
Pool environments are harsh: chlorine, salt, and UV exposure wear down motors over time. Genuine Dolphin parts (Maytronics certified) are manufactured to original equipment specifications, ensuring they withstand years of use. The Bzcovac motor also claims enhanced durability and comes with a one-year warranty. The Betta motor rotor set is made of durable plastic and propellers designed for continuous skimming. For long-term reliability, consider brands you trust. If you need other running gear, AIPER replacement wheels offer similar quality for cordless cleaners.
Ease of Installation and Included Parts
Most motor units are direct replacements: you unplug the old motor, install the new one, and reconnect wires. The Betta set includes both left and right motor rotors with propellers, making it a complete swap. Dolphin units come as single motors without extra hardware. If you are handy with a screwdriver, installation takes about 30 minutes. For more complex repairs, check the dolphin wheel replacement kit if your robot also needs new wheels.
Final Thoughts
Choosing the right pool robot motor unit comes down to your cleaner’s make and model. For most Dolphin owners, the Dolphin Genuine Replacement Part (9995389-EX) offers broad compatibility and verified Maytronics quality. If you have a Betta solar skimmer, the Betta Genuine Robotic Pool Skimmer Motor Rotor set is an affordable, easy‑to‑install solution that restores smooth skimming. Both options will have your pool robot moving again in no time.
Frequently Asked Questions
How do I know which motor unit fits my pool robot?
Check your cleaner’s model number printed on the label (usually under the handle or on the body). Then match it to the compatibility list in the product description. Many Dolphin motors list specific series like S50, Active 10, or DX3. For Betta, ensure your model is Flex, SE Plus, or SE.
Can I replace the motor unit myself?
Yes, most replacements are straightforward. You will need a screwdriver and possibly a pair of pliers. The Betta rotor set snaps in without tools. Always disconnect power before opening your cleaner. If you are unsure, consult a professional.
What is the average lifespan of a pool robot motor?
With proper maintenance, a motor can last 3 to 5 years. Factors like pool chemistry, debris load, and usage frequency affect longevity. Replacing worn motors as soon as you notice reduced performance prevents damage to other components.
Are aftermarket motors as good as genuine OEM parts?
Some aftermarket options, like the Bzcovac motor, meet original specifications and include warranties. However, genuine Dolphin parts are certified by Maytronics and guarantee exact fit. For high‑end cleaners, OEM is recommended. Check our Betta category for more on that brand’s genuine parts.
