Yes — robots scrub algae off surfaces and can capture it, but only if you’re using fine enough filtration. Standard cartridges let algae particles pass straight back into the water, making it look like the robot "isn’t working." NanoFilters trap algae for a genuinely clear pool. For an active algae bloom, balance and shock the water first.
The filtration catch
Algae particles are tiny. A robot with a standard filter will brush algae loose and stir it up, but much of it flows right back through the filter — so the pool stays hazy and it looks like the robot failed. Swap in NanoFilters™ and the robot actually removes those micro-particles instead of recirculating them.
For an active bloom, treat first
If the pool is green, the robot is a finishing tool, not a first responder. The proven sequence is:
- Balance the water and shock it to kill the algae.
- Brush the walls and floor to break the algae loose.
- Let the dead algae settle out.
- Run the robot with NanoFilters to vacuum it up; rinse the filter and repeat as needed.
Ongoing prevention
Regular robot cycles disrupt the biofilm where algae starts and reduce the organic load that feeds it. Keep NanoFilters loaded during algae season, and see do I need NanoFilters. Shopping for a strong-scrubbing robot? Compare them on our robotic pool cleaners page.
