Picture this: your Dolphin Nautilus pool cleaner starts stalling on the pool walls, or it spins in place on the floor instead of climbing. That frustrating slip is almost always a sign the wheels have worn down. Over time, guide wheels, drive wheels, and even pulley gears can lose traction, causing your robot to miss debris and run inefficiently. Whether you own a Nautilus CC Plus, M400, or M500, knowing which replacement parts fit and perform is key to getting your cleaner back to peak condition. In this guide, we cover seven top-rated options, from genuine OEM parts to affordable aftermarket kits, so you can find the right fit for your model and budget.

If you own a Maytronics Dolphin pool cleaner and notice reduced movement or slipping, worn guide wheels and gears are often the culprit. The ANTOBLE replacement parts kit offers a straightforward fix. It includes four guide wheels and two pulley gears designed to fit a broad range of Dolphin models, from the Nautilus CC Plus to the M500 and beyond.
Standout features include the use of high-quality POM material, which is known for its strength and low friction. This means the parts should resist wear far longer than basic plastic alternatives. In use, the wheels and gears restore smooth tracking and traction, helping your cleaner cover the pool floor efficiently.
Build quality appears solid, with precise dimensions matching original parts. The guide wheels measure about 2.05 inches in diameter and 1.06 inches thick, while the pulley gears are slightly larger. Installation is simple, typically requiring just a screwdriver to swap out old components.
One potential downside is that this kit does not work with the older Nautilus CC model, so check your cleaner's model number before buying. Also, the manual measurement note suggests a possible slight variance, though most users should find a proper fit. As a new product with no reviews yet, long-term durability is unproven but the material choice inspires confidence.

Buying Guide
Compatibility with Your Dolphin Model
Not all wheels fit every Nautilus variant. The Dolphin Nautilus CC, CC Plus, CC Supreme, M400, and M500 all have different drive train designs. Double-check your model number and the part number (like 3884997-R6 or 9985006-R2) before ordering. For example, the Dolphin Genuine Replacement Part is compatible with CC Plus and Supreme but not the standard CC or CC Pro. Meanwhile, the 2 Pack Rear Wheel Replacement Part Compatible is specifically made for the standard Nautilus CC. Always match the part to your exact cleaner to avoid jamming or misalignment.
Material Quality and Durability
The material of the wheels directly affects how long they last. High-quality ABS plastic and reinforced POM (polyoxymethylene) offer superior wear resistance against pool chemicals and rough surfaces. The Pool Cleaner Replacement Parts Guide Wheels from ANTOBLE use POM for extended life. Climbing rings made of high-density sponge, like those in the 9985006-R2 Repair Kit for Dolphin Nautilus CC, add traction and reduce slipping. Avoid cheap plastic that can crack or deform after a few months.
Complete Kit vs. Individual Parts
Some buyers prefer a comprehensive repair kit that includes guide wheels, pulley gears, belts, and even filters. The 9985006-R2 Repair Kit for Dolphin Nautilus CC bundles a timing track, climbing ring, guide wheels, and pulley gears for a full refresh. On the other hand, if only the rear wheels are worn, a simple pack like the may be more cost-effective. Think about what your cleaner needs: do you see damage across multiple components or just one area? Ease of Installation Most wheel replacements are designed for do-it-yourself installation without special tools. Kits like the [acms_link asin=”B0F24FG4NJ”>Viskeysta Replacement Parts Kit Compatible claim a no-tools, 5-minute setup. However, some models may require disassembling the cleaner to access the drive system. If you are not handy, consider a kit with clear instructions or video guides. For more tips, read our top robotic pool cleaner drive wheel replacements guide.
Final Thoughts
Whether you need a quick fix with the 2 Pack Rear Wheel Replacement Part Compatible for a standard Nautilus CC or a full overhaul with the 9985006-R2 Repair Kit for Dolphin Nautilus CC that includes guide wheels and gears, the right replacement parts will restore your robot’s climbing power and cleaning efficiency. Choose based on your specific model and how many components show wear, and you will get your pool sparkling again without spending on a whole new cleaner.

Frequently Asked Questions
How do I know when my Dolphin Nautilus needs replacement wheels?
If your cleaner starts slipping on walls, stalling on steps, or moving erratically, the wheels likely have worn treads or cracks. Visually inspect the guide wheels and rear drive wheels for bald spots or deformation.
Can I replace just the guide wheels or do I need the whole kit?
You can replace only the guide wheels (like the 3884997-R6 sets) if they are your sole issue. However, if the pulley gears or climbing rings also show wear, a combo kit may save time and money in the long run.
Are aftermarket wheels as durable as genuine Dolphin parts?
Many aftermarket brands use quality materials like ABS or POM that match or exceed OEM durability. Genuine parts like the Dolphin 3884997-R6 ensure perfect fit, but alternatives from ANTOBLE or MNPARTS are often more affordable and validated by many users.
Will these wheels work with my Dolphin Nautilus CC Plus in 2026?
Yes, most of the kits and wheels listed are compatible with the CC Plus, but always confirm the part number. The 9985006-R2 kit and 3884997-R6 guide wheels explicitly list CC Plus support. For more model-specific advice, see our pool cleaner guide wheel replacement page.
