How to Clean and Maintain the Dolphin Nautilus CC Plus Filter

The short answer: Clean the Dolphin Nautilus CC Plus filter after every 3 to 5 cleaning cycles or when you notice reduced suction. Rinse it with a garden hose, use a filter cleaner for deep cleaning, and replace it every 12 to 18 months depending on usage. Proper maintenance keeps your pool clean and extends the life of your robot.

Why Filter Maintenance Matters

The filter is the heart of any robotic pool cleaner. The Dolphin Nautilus CC Plus uses a fine mesh filter that captures debris, dirt, and even small particles. Over time, the filter can become clogged, reducing water flow and suction. This makes the robot less effective, increases cleaning time, and can even strain the motor. Regular cleaning and maintenance ensure optimal performance and longevity.

Many pool owners forget about the filter until they notice a drop in cleaning quality. By then, the filter might be heavily clogged, and the robot may have been working inefficiently for several cycles. Making filter maintenance a routine part of your pool care schedule is the best way to avoid this.

Step by Step: How to Clean the Filter

Cleaning the Dolphin Nautilus CC Plus filter is straightforward. Follow these steps for best results:

1. Turn off and unplug the robot: Always disconnect the power supply before handling the robot. Place it on its side or upside down on a flat surface.
2. Remove the filter cartridge: The filter is located at the front of the robot. Press the release latch to open the filter door, then pull the cartridge out. You might need to use a bit of force, but it should slide out easily.
3. Rinse with a garden hose: Use a high pressure spray from the bottom side of the filter to push the debris out. This is the most effective way to remove dirt and leaves. For heavy debris, you can also tap the filter gently to dislodge particles.
4. Deep clean with a filter cleaner: Every 2 to 4 weeks, especially during heavy pool use, soak the filter in a solution of water and filter cleaner (available at pool supply stores) for 15 to 30 minutes. This breaks down oils and fine particles that water alone can’t remove.
5. Rinse thoroughly and air dry: After cleaning, rinse the filter with clean water to remove any cleaning solution. Let it air dry completely before storing or using it again. Never put a wet filter into the robot for storage.

Remember to clean the filter debris that may be stuck in the filter chamber and the inlet. Use a cloth to wipe away any slime or debris.

How Often Should You Clean the Filter?

The frequency depends on your pool usage and environment. Here’s a general guideline:

• For typical residential pools, clean the filter after every 3 to 5 cleaning cycles. If you run the robot daily, that means cleaning the filter every 3 to 5 days.
• If you have a lot of trees or debris, you may need to clean the filter after every cycle.
• If you notice reduced suction or the robot is leaving debris behind, check the filter first.

It’s better to over clean than under clean. A clean filter ensures maximum suction power and better cleaning results.

When to Replace the Filter

Even with regular cleaning, the filter will eventually wear out. Look for signs of wear such as:

• Tears or holes in the mesh
• Loss of shape (filter not fitting snugly)
• Permanent discoloration or odor that doesn’t wash away
• Reduced performance despite regular cleaning

Typically, the filter should be replaced every 12 to 18 months, but if you run the robot frequently, you might need a new one sooner. Always use genuine Dolphin replacement parts to ensure compatibility and performance.

Additional Maintenance Tips

Here are a few extra tips to get the most out of your Dolphin Nautilus CC Plus:

• After each cleaning cycle, check the filter for debris and rinse it if necessary. This takes less than a minute and saves you time in the long run.
• Store the robot and filter in a cool, dry place away from direct sunlight and extreme temperatures.
• Inspect the filter for damage every time you clean it. Catching a tear early can prevent debris from entering the motor.
• Use the robot’s caddy or storage bag to keep the robot organized and protected.
• Keep an extra filter on hand so you can swap it out if one is drying.

Following these simple steps will keep your Dolphin Nautilus CC Plus running efficiently for years.

Filter Types and Compatibility

The Dolphin Nautilus CC Plus typically comes with a standard fine filter cartridge, but there are also ultra-fine and coarse options available. The standard filter is designed to capture common debris like leaves, dirt, and small insects. If your pool has fine particles such as sand or algae, an ultra-fine filter can provide better filtration. Conversely, if your pool has larger debris like leaves, a coarse filter may be more suitable to prevent clogging. It’s important to use filters specifically designed for the Nautilus CC Plus to ensure a proper fit and optimal performance. Aftermarket filters may be cheaper, but they might not seal correctly, allowing debris to bypass the filter and reach the motor. Always check the manufacturer’s specifications for compatible part numbers.

Common Mistakes to Avoid

Even well-intentioned pool owners can make mistakes that harm the filter or reduce cleaning efficiency. Here are some common pitfalls and how to avoid them:

• Using a pressure washer: As mentioned in the FAQ, high pressure can damage the filter mesh. Stick to a garden hose with a spray nozzle.
• Not allowing the filter to dry completely: Storing a damp filter can lead to mold and mildew, which can cause odors and degrade the filter material. Always air dry before storing.
• Ignoring the filter chamber: Debris can accumulate in the chamber where the filter sits. Wipe it out regularly to prevent buildup that can restrict water flow.
• Over-tightening the filter door: The filter door should close securely but not be forced. Over-tightening can crack the plastic or damage the latch.
• Using harsh chemicals: Only use filter cleaners designed for pool filters. Household detergents can leave residue that harms the filter and pool water chemistry.
• Neglecting the impeller: The impeller, located near the filter, can become tangled with hair or debris. Check it periodically and remove any obstructions to maintain suction power.

Long-Term Storage and Off-Season Care

If you live in an area with cold winters, proper storage of your Dolphin Nautilus CC Plus during the off-season is crucial. Before storing, clean the filter thoroughly and let it dry completely. Store the robot and its components in a dry, temperature-controlled environment. Extreme cold can make the plastic brittle, and extreme heat can warp components. It’s also a good idea to remove the filter and store it separately in a breathable bag to prevent moisture buildup. Additionally, inspect the power supply and cable for any signs of wear or damage before storing. This way, when swimming season returns, your robot will be ready to go.

Frequently Asked Questions

Q: Can I use a pressure washer to clean the filter?

It is not recommended. A pressure washer can force debris deeper into the mesh or damage the filter material. A garden hose with a nozzle is sufficient.

Q: How often should I replace the filter?

On average, every 12 to 18 months. However, if you notice reduced performance even after cleaning, or visible damage, replace it sooner.

Q: Can I put the filter in the dishwasher?

No. The heat and detergents can warp or damage the filter material. Stick to hand washing with water and filter cleaner.

Remember, regular maintenance is key. By keeping the filter clean, you ensure your Dolphin Nautilus CC Plus picks up all the dirt and leaves, leaving your pool sparkling clean. Happy swimming!
