Your pool robot used to glide effortlessly across the water, leaving a trail of sparkling clean surfaces. But lately, it struggles to climb walls, moves sluggishly, or leaves debris behind. Before you consider a costly replacement, check the impeller. This small but vital component creates the suction that drives cleaning and wall adhesion. When it wears out, performance drops dramatically. In this guide, we cover everything you need to know about finding the right pool robot replacement impeller for your Dolphin or Hayward cleaner, with eight top-rated options evaluated for compatibility, durability, and ease of installation. If you are exploring other replacement parts, our Replacement Parts hub offers guides for batteries, chargers, and more.
Pros
- Affordable replacement part compared to full cleaner repair or replacement
- Easy to install with the supplied screw and basic tools
- Durable polyamide material resists corrosion from pool chemicals
- Restores original cleaning performance and mobility
- Wide compatibility with many Maytronics Dolphin models
Cons

The Alocs 9995266-R1 impeller is a purpose-built replacement part for Maytronics Dolphin robotic pool cleaners. It is designed for owners of models like the Premier, Nautilus CC, and many others who notice their cleaner losing suction or struggling to climb walls. This part directly addresses the most common reason for decreased performance: a worn impeller.
The standout quality of this impeller is its construction from polyamide, a material chosen for its strength and resistance to corrosion. In real-world use, this translates to a part that holds up against chlorine and saltwater without degrading quickly. Users can expect a restored cleaning ability, with the pool cleaner once again moving efficiently and picking up debris.
Installation is straightforward: remove the old impeller, attach the new one using the included screw, and tighten it securely. The design matches the original dimensions exactly, so no modifications are needed. This simplicity makes it accessible for most DIY pool owners, though a basic screwdriver is required.
A potential drawback is that compatibility is limited to the models listed; newer or non-Dolphin cleaners will not work. Also, the package includes only the impeller and screw, so if other parts are worn, they must be purchased separately. Despite this, for those with a compatible cleaner, this is a highly targeted fix.
Overall, the Alocs 9995266-R1 impeller is a reliable and cost-effective solution for restoring your Dolphin pool cleaner to peak performance. If your unit is sluggish or fails to climb, replacing the impeller is often the first step, and this part delivers on fit and durability.

Buying Guide for Pool Robot Replacement Impellers
1. Compatibility: Match the Part Number and Model
The most critical factor is ensuring the impeller fits your specific robot. Impellers are designed for either Maytronics Dolphin cleaners (common part numbers 9995266-R1 and DL9995269R1) or Hayward models (RCX11000). Using the wrong impeller can cause poor suction, noise, or even damage. Always verify your robot’s model and original part number before ordering. For example, the Alocs DL9995269R1 Pool Cleaner Impeller with Screw fits a wide range of Dolphin units including DX3, DX4, and C5, while the Hayward RCX11000 Impeller Replacement for Select fits SharkVac and TigerShark models.
2. Material Quality: Look for Polyamide Construction
Impellers endure constant water flow, debris impact, and chemical exposure. High-quality polyamide (nylon) offers excellent mechanical strength, corrosion resistance, and wear resistance. All eight products in our list use polyamide. Avoid impellers made from unknown or brittle plastics, as they may crack or deform quickly. Brands like Alocs, Pokin, and deawater specify polyamide in their listings, ensuring long-lasting performance.
3. Ease of Installation: Screw and Tool Requirements
Most replacement impellers come with a mounting screw and can be swapped in under ten minutes. The typical process involves removing the top cover, unscrewing the old impeller, and installing the new one with a hex-head screwdriver or Allen wrench. Kits that include the screw save a trip to the hardware store. The Pool Cleaner Replacement Parts Impeller Assembly from Pokin includes both impeller and screw, and instructions are straightforward. If you own a Hayward model, the deawater RCX11000 Pool Cleaner Impeller with Screw is a budget-friendly option that installs just as easily.
4. Performance Restoration: Suction and Wall Climbing
A worn impeller reduces water flow, which directly impacts the robot’s ability to climb walls and pick up debris. Replacing it with a new impeller can restore original suction and cleaning efficiency. Many users report immediate improvements in waterline scrubbing and corner cleaning after swapping the impeller. For Dolphin owners, the Alocs 9995266-R1 Pool Cleaner Impeller is rated highly for bringing back wall-climbing power. For Hayward users, the Pool Cleaner Impeller RCX11000 with Screw from Alocs is a reliable choice.
To extend the life of your new impeller, clean it weekly or bi-weekly. Debris buildup can strain the motor and reduce efficiency. For more maintenance tips, check our guide on Beatbot Replacement Battery Picks and AIPER pool cleaner charger.
Final Thoughts
Choosing the right pool robot replacement impeller comes down to matching your cleaner’s model and prioritizing durable materials. For Dolphin owners, the Alocs DL9995269R1 Pool Cleaner Impeller with Screw offers excellent compatibility and a high rating for restoring suction. For Hayward users, the Hayward RCX11000 Impeller Replacement for Select is a trusted OEM-grade option that reliably fits SharkVac and TigerShark models. Both products are easy to install and backed by solid customer feedback. Whichever you choose, a fresh impeller will breathe new life into your robotic pool cleaner, saving you the cost of a full replacement.
Frequently Asked Questions
How often should I replace my pool robot impeller?
With regular use, an impeller typically lasts one to two seasons. If you notice reduced suction, slower movement, or poor wall climbing, it is time to inspect and possibly replace the impeller. Cleaning it weekly can extend its lifespan.
Will a new impeller improve wall climbing?
Yes, the impeller generates the water flow that creates suction and thrust for climbing. A worn impeller loses efficiency, causing the robot to slip. Replacing it restores the force needed to scale walls and tackle waterlines.
Can I use a Dolphin impeller in a Hayward cleaner?
No, impellers are designed for specific motor housings and mounting points. Dolphin impellers (9995266-R1, DL9995269R1) are not compatible with Hayward models (RCX11000). Always check your robot’s brand and part number before purchasing.
What tools do I need to replace the impeller?
Most replacements require a hex-head screwdriver or an Allen wrench. Some models use a Phillips screw. The included screw in most kits matches the original. No special skills are needed; the whole process takes about 10 minutes. For more guidance, visit our pool robot charging station replacement for similar DIY tips.
