FAQ

Robotic Pool Cleaners — FAQ

How do I know if the replacement cable fits my cleaner?

Check the product listing for specific model compatibility, such as the dolphin nautilus plus pool cleaner. Ensure your unit has the same prong configuration as the replacement cable.

Is Wi-Fi necessary for a pool cleaner?

Wi-Fi is not required but offers convenience for remote scheduling and status updates. It is highly recommended for users who want to manage their cleaner via a smartphone app.

What is the difference between active and passive brushes?

Active brushes spin independently to scrub surfaces, while passive brushes rely on the cleaner's movement. Active scrubbing is generally more effective at removing algae.

Can these cleaners handle stairs?

Most robotic cleaners are designed for walls and floors but may struggle with steep stairs. Check the product specifications regarding wall-climbing capabilities.

How often should I clean the filter basket?

It is best practice to rinse the filter basket after every cleaning cycle. This prevents debris buildup and maintains optimal suction power.

Do I need to leave the cleaner in the pool?

No, it is recommended to remove the cleaner from the pool after the cycle is complete. This helps extend the life of the motor and internal components.
