FAQ

Robotic Pool Cleaners — FAQ

How does the Explorer E40 compare to a dolphin 300i pool cleaner?

The Explorer E40 offers similar high-end features like waterline scrubbing and Wi-Fi connectivity. It serves as a powerful alternative for those comparing premium robotic cleaners.

Are these cleaners suitable for above-ground pools?

Most of these models are specifically engineered for inground pools. Always verify the wall-climbing and length specifications before purchase.

How often should I clean the filter?

It is recommended to rinse the filter basket after every cleaning cycle. This ensures maximum suction power for the next use.
