FAQ

Robotic Pool Cleaners — FAQ

How do these compare to a dolphin m400 pool vacuum?

While the dolphin m400 pool vacuum is a well-known benchmark, these models offer competitive features like Wi-Fi and advanced scrubbing. Each listed unit targets specific needs like budget or pool size similar to industry standards.

Do I need Wi-Fi for my pool cleaner?

Wi-Fi is not strictly necessary, but it allows for convenient scheduling and remote control. It is a great feature for those who prefer managing their pool maintenance via a smartphone app.

How often should I clean the filters?

It is recommended to clean your filters after every cycle to ensure optimal suction. Top-loading models make this process quick and efficient.

Can these cleaners handle stairs?

Most robotic cleaners are designed for floors and walls. While some may navigate shallow steps, they are primarily optimized for flat surfaces and vertical pool walls.

What is the benefit of an active scrubber?

An active scrubber rotates independently to loosen debris that static brushes might miss. This leads to a more thorough clean on both pool floors and walls.

Are these cleaners suitable for all pool surfaces?

Most models are designed for standard inground pools. Always check the product specifications to ensure compatibility with your specific pool finish, such as vinyl, tile, or concrete.
