FAQ

Robotic Pool Cleaners — FAQ

How often should I replace my filters?

Replacement frequency depends on usage and water conditions. Generally, inspect them every season and replace if you notice tears or reduced suction.

Are these filters compatible with all Dolphin models?

No, compatibility varies significantly by series. Always check the specific model list in the product description before purchasing.

What is the difference between a leaf bag and an ultra-fine filter?

Leaf bags have a higher micron rating for large debris, while ultra-fine filters catch dust and algae. Use the appropriate type based on your current pool state.

Can I wash these filters?

Most cartridge-style filters can be rinsed with a garden hose. Avoid using high-pressure sprayers which may damage the delicate mesh.

What does the micron rating mean?

The micron rating indicates the size of particles a filter can capture. A lower number means the filter can trap finer, smaller particles.

Why is my cleaner losing suction?

Suction loss is often caused by clogged or damaged filter cartridges. Replacing old filters usually restores the cleaner's original performance levels.
