Brush and vacuum weekly
Brushing prevents algae before it shows up. Vacuuming gets the corners your robot misses.
What you'll learn
- Why brushing is the #1 algae prevention tool
- Nylon brush for plaster, stainless for gunite (never stainless on vinyl)
- Which spots to hit every time (steps, corners, shade, behind ladders)
- Whether a robot cleaner is worth the investment
Step by step
- Use the right brush: nylon for plaster/aggregate, stainless for gunite.
- Start at the shallow end. Brush walls downward toward the main drain.
- Focus on steps, seats, corners, and shaded areas.
- For manual vacuuming: attach head + hose to pole, prime hose, connect to skimmer.
- Move slowly in overlapping stripes. Rushing stirs dust back up.
Safety note
A robot cleaner (Dolphin, Polaris) takes the vacuum chore off your hands and works the floor more consistently than most people manage by hand.
