If your Maytronics Dolphin pool cleaner is starting to drag or show uneven movement, worn guide wheels and pulley gears are often the culprit.

It is a cost-effective way to extend the life of your cleaner without replacing the entire unit.
The standout feature of this kit is its broad compatibility. It works with over 20 models, making it a versatile choice for many pool owners. The parts are made from high-quality materials that are resistant to cracking and wear, which should help them last longer than the original components.

Design and build quality are straightforward. The white plastic wheels and gears match the original specifications, and the set includes everything needed for a typical replacement. Installation is relatively simple for anyone comfortable with basic disassembly, though you may need a screwdriver and some patience. The parts are not compatible with Nautilus CC or Nautilus CC Pro models, so be sure to check your cleaner before purchasing.
One potential drawback is the lack of customer reviews, so real-world performance data is limited. However, based on the materials and compatibility claims, this kit appears to be a solid alternative to OEM parts. The price point is reasonable for a set that can restore your cleaner's functionality.
Overall, the Vsttar 3884997-R6 guide wheels and pulley gears are a practical solution for owners of compatible Dolphin pool cleaners.

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.
Overall, the ANTOBLE replacement kit is a practical, affordable solution for refreshing your Dolphin cleaner's drive system. If you need a quick fix to restore performance without paying OEM prices, this set is a solid choice.
Buying Guide
Compatibility with Your Dolphin Model
Not all replacement wheels fit every Dolphin Nautilus model. For instance, the Nautilus CC Plus uses different guide wheels and gears than the standard Nautilus CC. Always check the product description for model compatibility before purchasing. Many kits list compatible models like M400, M500, DX3, DX4, and more.
For example, the Best Pool Robot Replacement Parts for Polaris guide offers similar compatibility insights for a different brand. Apply the same diligence here.
Material Quality and Durability
Wheels and guide wheels take constant abuse underwater. Look for parts made from high-quality ABS, POM, or reinforced polymers. These materials resist cracking, wear, and aging. High-density sponge climbing rings also last longer than standard foam.
Brands like MNPARTS and ANTOBLE use premium materials that have been validated through user feedback. Avoid cheap plastics that may deform or break after a few months.
Kit vs. Individual Parts
Buying a repair kit often saves money and time. Kits like the 9985006-R2 include guide wheels, pulley gears, climbing rings, and timing tracks. This ensures all worn components are replaced at once. Individual parts are better if only one component fails.
For more on specific components, see our best pool cleaner replacement wheels for polaris guide, which covers similar considerations.
Ease of Installation
Most replacement wheels and guide wheels are designed for DIY installation. Look for products that require no special tools. Some climbing rings need soaking in water to expand before installation. Clear instructions and a simple process save you repair costs.

Final Thoughts
For most Dolphin Nautilus owners, the 9985006-R2 Repair Kit for Dolphin Nautilus CC offers the best value by replacing multiple worn parts at once, restoring climbing and cleaning performance. If you need a quick and affordable fix for guide wheels alone, the 3884997-R6 4 Guide Wheels&2 Pulley Gears from Vsttar is a reliable choice that fits many models. Both options will keep your pool robot running smoothly through the season.
