Clean Only After Treatment Conditions Permit
A robot can collect settled dead-algae residue, but it should enter the pool only after the treatment instructions and cleaner manual say conditions are acceptable. Do not assume that clear-looking water or settled dust means the bloom is fully treated.
Fine pleated media can retain smaller residue than coarse mesh, but it may load quickly and may not remove everything in one pass. A large amount of settled material can be better suited to a manual vacuum-to-waste setup when the pool system supports it and water-loss rules allow.
Post-Treatment Cleanup Sequence
- Complete testing, treatment, and circulation according to the chemical label or qualified pool-care guidance.
- When equipment conditions are acceptable, remove large debris and run a normal cycle over the settled film.
- Rinse the filter away from the pool, inspect its fit, and let disturbed residue settle before deciding on another pass.
- Retest water independently; mechanical pickup does not establish sanitizer or pH levels.
Know When the Robot Is Not Enough
If the material remains attached, continues growing, or returns while chemistry is off, go back to the algae-treatment guidance. Surface texture also affects cleanup: review gunite or plaster care before aggressive manual brushing.
After each loaded cycle, rinse the media, inspect brushes with power disconnected, and follow the maintenance guide. A timer may support routine debris removal later, but it does not prevent algae by itself.
