ESSENTIAL FEATURE
Waterline Cleaning
Clean where it matters most. The dirtiest part of your pool.
Where is the Waterline?
Also Known as the Scumline
The waterline is where the pool water meets the air. It's the dirtiest part of any pool—where bacteria, dirt, and algae grow. These organisms are hard to remove and can be a risk to swimmers if not taken care of.
Why is Waterline
Cleaning Important?
A pool with build-up at the waterline can be an eyesore—then turn into a real issue if not taken care of. Over time, algae, dirt, and grime can build up and stain your pool walls.
Before robotic pool cleaners, pool owners were left to manually scrubbing by hand. Not anymore.
