Pool Robot Cleaners to Remove Waterline Stains

Just by looking at it, you will agree that the waterline is the dirtiest part of your pool. It’s the spot where water and air meet. With impurities and chemicals present in the water, all these elements mix together to form a nasty film that clings to the tile materials. Over time, they harden to create stains and scale.

Understanding the Problem

The waterlines are hardened impurities that you see in the pool, sink and bathtubs. They appear more often in the pool where water remains undisturbed longer.

What causes waterline stains? The answer is water evaporation.

When water evaporates, it leaves calcium deposits on the sides of the pool. The marking stays on the tiles and hardens into scales. The scales look like white or brownish scum that is visibly noticeable. They make the pool look ugly and uninviting to swim at.

Aside from dirt and other foreign materials, a waterline scaling has two types:

1. Calcium silicate.

These are the white-grey films on the pool’s surface. Of the two, calcium silicate is tougher to remove when it hardens. The first thing you can do to get rid of it is to apply muriatic acid to the waterline tiles. If that’s not enough, arm yourself with a pumice stone and start rubbing the scum.

2. Calcium carbonate.

This is the white foam on the surface of the pool. When it hardens, you can use a pumice stone to remove it. Drop some muriatic acid on the scale to see if you’re dealing with this element. If it sizzles, that confirms that indeed it is calcium carbonate.

Pool stains can appear in various colors depending on the chemical composition of the water.

Dealing with Waterline Scaling

Removing scales and stains can take some time. The best cure for this problem is to prevent it from forming or minimize its appearance. There are many ways to do it, such as:

Cleaning Tile

Cleaning pool tiles focusing on the waterline area is the best way to get rid of waterline scaling.

You don’t have to wait until the whitish film thickens before you act. You can start scrubbing waterline scum while they are still thin. All you need is a brush or a scrubbing pad and a good amount of muriatic acid.

Sealing Tile

Once cleaned, apply a sealant on the tile to prevent dirt from sticking to them. A good sealant will protect tiles from the mineral deposit and UV exposure. It makes the tile look new and leaves a natural luster.

To apply the sealant, make sure that the tiles are dry. You can use as many as three coats to ensure properly sealed tiles.

Keeping the Water Clean

Keeping your tile clean is one of the best preventive measures against waterline scaling. Doing regular pool maintenance prevents calcium build.

Choose environment-friendly solutions when cleaning the tiles. It will also help to keep the water chemistry and temperature within the recommended range. If your pool continuously produces a high calcium concentration, you may consider installing a reverse osmosis system to eliminate minerals in the water.

Best Robotic Pool Vacuum for Waterline Cleaning

If you want to cut off cleaning time by half and without you doing most of the dirty work, buying a robotic pool cleaner is the best way to go. This machine is designed to automatically clean your swimming pool without turning on the skimmer and filtration system. A pool robot has its own power supply and filters to suck contaminants like dirt, algae, and other types of debris.

If you’re looking for one, choose a model designed for inground pools. This cleaner can climb the sides made from tile, fiberglass, or cement. Cleanup.Expert comes up with a list of the important features you need to consider when buying a robotic pool vacuum. One of them is buoyancy – the ability of the machine to stay longer in the waterline for better scrubbing.

If you want some insight as to which model to buy, here are our top picks:

DOLPHIN Nautilus CC Supreme

CC Supreme has a triple threat cling mechanism equipped with motors, three scrubbing brushes, and a filtering system. If you think it’s intimidating to use this bot, you’re wrong. CC Supreme is user-friendly and has a powerful motor that efficiently cleans the floor and waterline.

This premium cleaner has interactive pool cleaning technology, allowing connection to an app via WiFi connection. MyDolphin Plus App on the phone will enable you to set up a cleaning schedule, choose a cleaning mode, and spot clean specific scum-prone areas like the waterline.

DOLPHIN Premier

Another model from a Dolphin brand that made our list is the Dolphin Premier. This robot has a drop-and-go feature for ease of use. It can cover an area of up to 50 feet. CleaverClean technology efficiently finds the waterline with its advanced algorithms for better pool coverage. With the help of an anti-tangle swivel cable, this Dolphin can go anywhere around the pool, scrubbing and sucking dirt in the process.

Polaris 9550 Sport

This auto pool cleaner has five cleaning modes to fit the type of cleaning you need. 9550 Sport is compatible with an in-ground swimming pool up to 60 ft. From a company with over 40 years of experience, 9550 Sport comes with a motion-sensing remote, Easy Lift System, and Vortex Vacuum technology for optimum cleaning performance.

DOLPHIN Sigma Robotic

Dolphin Sigma is smaller than the first two Dolphin models mentioned above. However, it also has outstanding features that make it one of the favorites of many pool-owners. Firstly, it has a 50 ft. anti-swivel cable to make climbing the waterlines easier. It also contains a massive top-loading cartridge to effectively capture fine debris. With the help of a powerful, dual scrubbing brush, this machine can effectively attack tough stains and scums.

Hayward W3RC9740CUB SharkVac

Hayward SharkVac uses a smart steering feature for a more accurate cleaning pattern. It can scour the floor to loosen up the dirt and suck the pollutants in less than two hours. One unique feature of this bot is the out-of-water sensor which protects the device from going out of the water. The sensor allows the bot to reverse its direction when it’s about to climb out of the water.
