Use Fine Media for Settled Dirt
A robotic cleaner can help with fine dirt after it settles, provided its filter media is fine enough and correctly installed. A coarse basket may collect grit while allowing the smallest visible residue to return to the pool. Pleated fine-media options trade some debris capacity for better particle retention.
A robot is not a diagnosis for cloudy water. Suspended soil may need circulation or settling time, while algae or an unbalanced pool requires separate water testing and treatment. If the residue is green or returns despite cleaning, start with the algae guidance instead of assuming the cleaner is at fault.
Plan for More Than One Pass
Remove leaves and other bulky debris first so fine media has room for dirt. Run a normal floor cycle, inspect the result after the water settles, and repeat only if needed. Recurring deposits may point to runoff, nearby construction, wind-blown pollen, dust, or a circulation issue that a robot cannot correct.
Maintain Fine Filters Carefully
- Seat every panel or basket seal as the manufacturer directs; a gap can let dirt bypass the media.
- Rinse after a visibly dirty cycle and clean between pleats without using tools that can damage them.
- Inspect the intake and impeller area only as described in the manual and with power disconnected.
- Replace media that remains damaged or no longer cleans up; see the robot maintenance guide.
Use the dedicated silt, mud, or dead-algae guide when the source changes the cleanup sequence. Return to the fine-dirt overview when more than one source is present.
