Vacuuming Dead Algae
Dead algae is extremely fine — finer than dust — and settles across the entire floor as a gray-green film. A robot with NanoFilters™ captures it in one pass instead of re-clouding the water. This is the single most common "day after shocking" problem we help customers solve. As one of the largest authorized dealers and retailers of robotic pool cleaners online, we've hand-tested 70+ robots across every major brand — every recommendation below comes from real poolside experience, and every unit we sell is factory-direct with a full manufacturer warranty.
Recommended Workflow
- Balance chemistry and shock the pool (brush walls first so the shock reaches everything — see our algae guide).
- Let the algae die and settle overnight with the pump off toward the end.
- Run a NanoFilter™-equipped Dolphin (Quantum, Premier, or Sigma) to vacuum it up.
- Rinse the filter and run a second cycle if the film was heavy.
Keeping It from Coming Back
Algae blooms repeat when organic debris accumulates. A robot on a weekly timer plus balanced chemistry breaks the cycle — and if your surface is algae-prone gunite or plaster, see those guides for surface-specific advice.
