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

- Installation requires some manual dexterity and a screwdriver
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
Compatibility with Your Dolphin Model
Before purchasing, confirm the impeller fits your specific Dolphin model. Manufacturers like Alocs and Ophjerg list compatible models, but it’s wise to double-check your robot’s part number. The 9995269-R1 fits DX3, DX4, DX5, and C5 models, while the 9995266-R1 works with Premier, Nautilus, and M series. Using the wrong impeller can reduce performance or cause damage.

Material Quality and Durability
Impellers face constant water exposure and debris impact. Most aftermarket options, like those from Alocs and Dfnidy, use polyamide or nylon, which resist corrosion and wear. Genuine Dolphin parts are also reliable but cost more. Look for products that specify high-quality materials to ensure longevity. A durable impeller maintains suction and reduces the need for frequent replacements.
Ease of Installation
Replacing an impeller is a DIY job that takes under 10 minutes. Most kits include a screw and require only a Phillips or flathead screwdriver. Products like the Alocs DL9995269R1 come with clear instructions. If you’re new to maintenance, our article on robotic pool cleaner replacement gear offers step-by-step advice. Easy installation saves you time and service costs.
Suction and Performance Restoration
A new impeller should restore water flow and wall climbing. Aftermarket options like the Ophjerg 2-pack claim to boost suction and speed. Verified reviews often note immediate improvements. For best results, clean the impeller area regularly to prevent clogs. Learn more about maintaining suction in our guide on robotic pool cleaner propeller replacement.

For a budget-friendly and highly rated option, the Alocs DL9995269R1 Pool Cleaner Impeller with Screw offers excellent compatibility and performance.
