Dealing with algae in your pool? You’re not alone. Algae can turn a sparkling oasis into a green nightmare almost overnight. To get your pool back in shape, you need more than just shock treatment—you need the right vacuum head built specifically to handle stubborn algae buildup. This guide breaks down the best pool vacuum heads for algae, what makes them effective, and how to choose the right one for your setup.
Why You Need a Special Vacuum Head for Algae
Algae is slippery, stubborn, and sneaky. It clings to pool surfaces and hides in hard-to-reach corners. A standard vacuum head might glide over the surface without actually scrubbing or sucking up the algae, which only lets it spread again.
A vacuum head that’s made for algae removal will:
-
Have strong suction and tight bristles
-
Be heavy enough to stay on the pool floor
-
Cover corners and tight spaces
-
Work effectively with your existing filtration or pump system
Without the right gear, you’ll just stir up the mess instead of removing it.
Best Overall: Milliard 14” Flexible Pool Vacuum Head
If you want a vacuum head that gets the job done every time, Milliard’s flexible vacuum head is the top pick for algae.
Key features:
-
Weighted body keeps it pressed to the pool floor
-
12 wheels and flexible design allow it to hug curves and corners
-
Nylon bristles on the bottom to dislodge algae while you vacuum
-
Fits 1.25” and 1.5” vacuum hoses
Why it’s great for algae: The combo of suction and scrubbing action means you can lift even stubborn green or yellow algae from the surface.
Best for: Concrete or plaster pools, especially those with irregular shapes
What to watch out for: Not ideal for vinyl pools—the bristles can be a little too aggressive.

If you’ve got a vinyl liner, you need something gentle but effective—this Poolmaster vacuum head hits the sweet spot.
Standout features:

Why it works for algae: The triangular shape lets you get into corners, and the bristles do a good job of scrubbing algae off without damaging your liner.
Heads-up: Because it’s lighter than some others, you’ll need a good pump for steady suction.

What Type of Vacuum Head Is Best for Algae?
The best type is a weighted, bristled vacuum head that can scrub while sucking up debris. For concrete and gunite pools, go with stiff bristles. For vinyl or fiberglass, choose soft bristles to avoid damage.
Here’s what to look for:
-
Weight: Prevents floating or tipping during use
-
Shape: Triangular or flexible heads reach tough spots
-
Bristles: Loosen algae for easy removal
-
Durability: Needs to withstand frequent use and harsh chemicals
Pro Tips for Vacuuming Algae Like a Pro
Getting the right vacuum head is step one. Step two? Using it the right way. Here’s how to get the most from your algae clean-up session:
-
Brush first: Use a dedicated algae brush to loosen buildup the night before.
-
Turn off your pool pump for a few hours to let algae settle at the bottom.
-
Use the manual vacuum mode—automatic vacuums often just stir algae around.
-
Move slowly: Quick movements stir debris back into the water.
-
Vacuum to waste if your system allows it—this prevents algae from re-circulating through your filter.
How Often Should You Vacuum Algae?
If you’re actively fighting an algae bloom, vacuum your pool daily until it’s gone. For prevention, once a week during peak swimming season is ideal.
If you’re noticing green patches coming back quickly, check your:
-
Pool chemistry (especially chlorine and pH)
-
Circulation system
-
Filter performance
Even the best vacuum head won’t help if your water balance is off.
Conclusion
Algae doesn’t stand a chance if you’ve got the right tools. A quality vacuum head can turn a frustrating green pool into a clean, clear oasis. Whether you need something heavy-duty for tough stains or a gentle touch for vinyl liners, there’s a perfect match for your pool and budget.
