The Essential Feature

Waterline Cleaning

Clean where it matters most

Waterline Cleaning

Where is the waterline?

Also known as the scumline, the waterline is where the pool water meets the air. The dirtiest part of any pool is the waterline, as bacteria, dirt, and algae grows here. These organisms are hard to remove and can be a risk to some swimmers if not taken care of.

Clean where most robots won't. The Waterline.

Why is waterline cleaning important?

A pool with a ton of build-up at the waterline be an eyesore at first, then turn into a real issue if not taken care of. Over time, this 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. And even once removed, it most likely could leave a noticable and unattractive ring around your pool. Not only that, but it can also lead to water health issues if you don't keep your waterline in check. To keep your pool beautiful and pool water healthy, we recommend making sure your waterline is cleaned and regularly scrubbed.
