A Robot Is a Cleanup Tool, Not an Algaecide
Choose a robot for mechanical brushing and pickup after water chemistry has been tested and the algae treatment is complete. Active brushes can loosen material from reachable surfaces, and fine media can retain some of the dead residue that settles. Neither function sanitizes the water.
Do not place the cleaner in unusually concentrated treatment water unless both the chemical label and robot manual allow it. Follow the treatment instructions, maintain circulation as directed, and consult a pool professional when the cause or safe re-entry conditions are unclear.
Match Coverage to the Affected Area
A floor-only cleaner can help with settled residue but will not scrub walls. If buildup reaches the tile line, compare models intended for waterline coverage; performance still varies with pool shape, surface, and conditions. Rough gunite or plaster may also need manual brushing in areas the robot misses.
Post-Treatment Cleanup
- Complete the chemistry treatment and circulation steps exactly as directed by the product label or pool professional.
- When conditions are within the robot manufacturer's limits, remove large debris and run a normal cycle with suitable fine media.
- Rinse the filter away from the pool and inspect the brushes and intake before another cycle.
- Retest the water separately; a visually cleaner floor does not make sure balanced or sanitized water.
For settled residue, continue with the dead-algae guide. A scheduled cleaning routine can remove ordinary debris, but it cannot prevent algae when circulation or chemistry is inadequate.
