Do Fiberglass Pools Need Automatic Cleaners?

Since fiberglass pools are such low-maintenance, do you even need a robotic pool cleaner? The answer is YES. Just because the pool is easier to clean, doesn’t mean that it shouldn’t be well and thoroughly maintained. A robotic cleaner for fiberglass pool gives you that peace of mind that you need to know that your pool is always sufficiently cleaned. Plus, a robotic pool cleaner cleans more than your pool surface, it also filters your pool water, cleaning it from sand and finer debris. But can’t other cleaners do that too? Here’s why you should choose a robotic cleaner for fiberglass pool over other types.

Manual vs. Robotic

While it’s true that robotic pool cleaners can be a significant expense, they can save you so much more. Having a cleaner for fiberglass pool means that you won’t have to do the hard work. The cleaner can be set according to a timer, and will regularly clean your pool, effortless and hassle-free. Furthermore, they’ll save you power, as they work separately from your filtration system and eliminate the need to pump out the water. Last but not least, your cleaner for fiberglass pool can spot the dirt that a manual cleaner simply can’t. It is equipped with sensors, navigation system and a control app, all of which are there to ensure the cleaning experience is thorough and efficient.

How to Maintain a Fiberglass Pool

Simple and low-maintenance are the keywords to describe your fiberglass pool maintenance. And yet, there are a couple of tips that you just can’t miss. We’ve compiled the main steps to maintaining your fiberglass pool, from cleaning, through chemistry and different pool surfaces.

  • Water chemistry maintenance

Every pool’s water has to be maintained through a proper balance of the chemicals in it. The ideal pH levels for a fiberglass pool are between 7.2 to 7.6 and the alkalinity should be 80-120 ppm. The chemicals in your pool can be measured with a home kit, though it is recommended that you consult a specialist every now and then.

  • Fiberglass Pool Cleaning

Have you been wondering what to use to clean a fiberglass pool? The best and simplest answer would be a robotic pool cleaner for fiberglass pools. If your fiberglass pool is placed under a tree, you may have witnessed leaves, bugs and even branches. That is exactly why you need a robotic cleaner that can tackle all these. Such a cleaner could also scrub out and filter some of the finer debris, like sand, algea and other bacteria. All you need to do is set the timer on your cleaner, and you’re good to go!

  • Surface Maintenance

Your cleaner for fiberglass pool can do more than filter your water, with the right system, it can brush and scrub your pool surface. A quality cleaner for a fiberglass pool will also be able to thoroughly scrub your pool surface, walls and waterline. Plus, cleaner for fiberglass pool does not require the use of harsh chemicals, and is built to protect your fiberglass pool from any potential scratches to your pool surface.

  • Maintaining Water Level

The best way to clean fiberglass pools and ensure they operate to their fullest, is keeping the pool’s water level at the center of your skimmer plate. The water levels cannot be too low or high, because they might then affect the effectiveness of your pool’s equipment. While balancing your pool’s water level, make sure not to pump the water out on your own – you will need a professional for this process, as pool drainage requires certain procedures to preserve its intactness. The same goes to fiberglass salt water pool maintenance.


Fiberglass pools are a great choice – they’re not only low-maintenance, but they’re also easy to maintain. So if convenience was your main reason to invest in a fiberglass pool, a cleaner for fiberglass pool should be a no-brainer. The robotic pool cleaner will essentially mean that all you need to do is set the weekly schedule and enjoy your family time, in the cool clear water.
