Buying Guide

Key Features to Consider

When selecting a Dolphin Nautilus model, prioritize the cleaning cycle options and filtration system. Top-tier models feature multi-media filtration, capturing both large debris and fine algae, which is essential for maintaining crystal-clear water. Additionally, look for advanced navigation technologies like Gyro navigation or Swivel cable systems, which prevent tangling and ensure systematic floor, wall, and waterline coverage for a comprehensive clean.

Budget Recommendations

Entry-level Nautilus units typically range from $600 to $800, offering reliable floor cleaning for standard in-ground pools. Mid-range models, priced between $900 and $1,200, often include wall-climbing capabilities and enhanced weekly timer functions. For premium performance, expect to invest upwards of $1,300 for features like Bluetooth connectivity, rapid cleaning cycles, and superior debris management suited for larger or more complex pool shapes.

Common Pitfalls to Avoid

A frequent oversight is purchasing a cleaner incompatible with your pool surface type; always verify specifications for vinyl, fiberglass, or gunite to prevent damage. Additionally, avoid ignoring cable length requirements, as a short power cord will severely limit the cleaner’s reach. Finally, do not underestimate the value of a lightweight design and easy-to-access filter compartments, as cumbersome maintenance can lead to neglected cleaning routines.

Frequently Asked Questions

Why is my Dolphin Nautilus not moving or moving in circles?

If the cleaner is not moving or is stuck moving in circles, it is likely due to a tangled floating cable or debris trapped in the tracks or brushes. First, untangle the cable and ensure it is not kinked. Second, remove and inspect the brushes and tracks for small rocks, twigs, or debris that might be obstructing the movement mechanism.

How often should I clean the filter cartridge or basket?

For optimal performance, it is recommended to clean the filter basket or cartridge after every cleaning cycle. This prevents clogging, maintains strong suction, and extends the life of the motor. Simply remove the basket, hose it down with water, and let it air dry before reinserting it.

Can I leave the Dolphin Nautilus in the pool all the time?

No, you should not leave the robot submerged in the pool continuously. Chemicals and constant water pressure can degrade the seals and plastic components over time. It is best to remove the unit from the water after each cleaning cycle and store it in a shaded, dry area away from direct sunlight.

Does the Dolphin Nautilus climb pool walls and clean the waterline?

Yes, most models in the Dolphin Nautilus series are designed to climb pool walls and scrub the waterline. However, if the unit is not climbing, check that the brushes are clean and not worn out, and ensure the filter basket is not full, as this reduces the suction required for vertical movement.

What should I do if my Dolphin Nautilus will not turn on?

First, check that the power supply unit is properly plugged into a working outlet and that the LED indicator light is on. Inspect the power cable connection to the robot to ensure it is secure. If the power supply light is not on, try a different outlet; if it still fails, you may need to contact customer support for a power supply replacement.
