6 Best pool cleaner for fiberglass pools in 2022 [Buyer’s Guide] 

Owning a fiberglass pool is no wonder you’re in luck when it comes to pool maintenance. A fiberglass pool is durable, easy to maintain, and requires fewer chemicals. However, it still requires regular maintenance.

Choosing the best pool cleaner for fiberglass pools can be a time-consuming process. Each model has its own pros and cons. Here are our top picks for fiberglass pool cleaners to make things a little easier for you.

Which is the best cleaner for fiberglass pools?

Before we look at the best pool cleaner for fiberglass pools reviews, let’s consider the types of cleaners first. Here is a list of cleaners ranked from best to least favorable (starting with the top kind).

1- Robotic Pool Cleaners

The Automatic robotic pool cleaners do all the autopilot work and work independently. In other words, plug them in, drop them in your pool, and let them do their thing. The built-in washer lifts and collects debris from a built-in filter basket that spills when the job is done. You must remove the robot vacuum from the pool every time you decide to swim, which is the only real downside.

2- Pressure-Side Pool Cleaners

The pressure side model is ideal for picking up large debris in the in-flight collection bag. Additionally, it picks up dirt and other debris, but not as well as a robot vacuum. The main disadvantage of this type of cleaner is that it requires a booster pump to operate, but some models connect to existing pool pumps.

3- Suction-Side Cleaners

The third type of pool vacuum cleaner connects directly to the pool’s existing filtration system and collects debris in the existing pump basket. Read article about how does pool vacuum cleaner exactly work. These work well if the pump is the right size but are not suitable as they do not have a built-in collection function, and the suction power is not as high as a robot or pressure-side cleaner.

F9550 is an excellent all-purpose cleaner. Pick up the debris of all sizes and do it quietly. Don’t be disappointed if you want to dive into freshwater, read the newspaper, or drink coffee while cleaning the pool. It’s also cheaper than Dolphin Premier Robotic, so the reasonable question is why we don’t rank it by value alone.

This is the best pool vacuum for fiberglass pool for beginners. Also, not all pools are always clean. It can feel like forever responding when trying to access the repository remotely. Also, the stairs are not cleaned. This is why I think basic cleaning is more valuable than dolphins, but it’s recommended to invest more money in good equipment for these reasons.

  • Cleaner for fines
  • With great traction
  • Works well without supervision
  • Observation box
  • With motion-sensing remote

The Zodiac MX8 Suction Side Cleaner features powerful vacuum cleaner technology to maximize debris removal. You can connect the skimmer to a skimmer or a 1.5-inch vacuum line. Read it to know about how pool skimmer work. It has advanced dual navigation for excellent pool coverage without stuttering. Regardless of the size of your pool, you can thoroughly clean the pool’s walls, floors, and water lines.

This best robotic pool cleaner for fiberglass pools helps collect 99% of the debris in the pool while maintaining maximum cleaning power. I also find the cleaner easy to assemble since it only needs to be attached to a 1.5″ vacuum line or scraper.

Another feature I love about the cleaners is the X-Drive technology, which provides advanced dual navigation to cover the entire pool. Also, there are no hangers and cleaners to clean the walls, water lines, and floors.

Robot fiberglass pool cleaners are used in large pools up to 60 feet above the ground. Breeze 4WD can clean any surface, so it doesn’t matter what the pool looks like. Surface material can clean concrete, tile, and vinyl except for fiberglass.

Equipped with a rotating brush that softens the scrubbing of hard debris. Under the broom. Breeze 4WD runs on four wheels. It is, therefore, much faster, and you can quickly move the entire pool.

This best chlorine for fiberglass pool feature improves the adhesion of the fiberglass cleaner and makes it easier to climb walls. It makes your mind less likely to be upside down. However, some customers complain that 4WD only clears half of the walls and does not cover the entire pool.

Product specifications

  • Brand Polaris
  • Size 20 x 10 x 22.75 inches
  • Material Plastic
  • Style Inground Cleaner
  • Weight 14 pounds

In contrast to others, the Polaris Vac-Sweep 360 is the best robotic pool cleaner for fiberglass pools. In other words, it is operated using the water in the pool on the pressure line. We chose it because it was well-received by consumers. Tests have shown that reputation has significant value. The vacuum picked up large debris like leaves and twigs with ease, as well as small particles like sand. It’s not a big deal for the price.

On the other hand, what I had was that it was difficult to get traction with fiberglass cladding. You can still get the job done. Do not stare at this, as it can be frustrating. It is also clear that the floor is not designed for fiberglass pools. If you have one of these, you need to find another option. But still, the cleaning offered at sticker price is the highest dollar value of any model we’ve tested.

  • Easily removes large debris
  • Effective at cleaning particulates
  • Affordable
  • Filter Single Chamber Velcro Bag
  • Detailed Instructions
  • It doesn’t work on above-ground pools

Also, I love the robots’ ability to climb walls and clean floors. It helps to clean the pool at the push of a button.

  • size 23 x 20 x 14 inches
  • Weight 39.8 pounds
  • Style In-Ground Pools

If you prefer a fully functional intelligent robot vacuum for your fiberglass pool, the Oasis Z5i will not disappoint. Unlike the Nautilus CC Plus, you have the option to connect to the Oasis Z5i via Bluetooth and schedule a cleaning in the MyDolphin app.

Plus, if you need to clean certain parts of the pool before welcoming guests quickly, the Oasis Z5i has exceptional waterline scrubbing and spot cleaning features. Another feature I love is the combination of an oversized dual filter and dynamic dual scrubbing. Compared to the Nautilus model above, the Oasis Z5i is more suitable for removing algae and other hard-to-remove debris.

The final highlight worth mentioning is the 36-month long-term warranty. This is the most extended warranty Maitronics offers to Dolphin Cleaners. Overall, when comparing the prices of all dolphin cleaners, I found these two models to be the best and most cost-effective for fiberglass pools.

  • 36-month warranty

  • The cord is tangle-free

FAQs: Best pool cleaner for fiberglass pools

A fiberglass swimming pool is easy to maintain, durable and quick to install. It's expensive to set up and not easy to customize, but it's worth it in the future.

Concrete pools are highly durable and easy to customize, but they require maintenance. Also, installing a concrete pool can take a long time.

The size of the vacuum hose in the pool should be long enough for the vacuum port or scraper to touch the farthest corners of the pool, and there should be a depth tolerance at that point. You can pull one end out of the scraper port, pull it out with a pool vacuum cleaner, wrap it up, or remove it from the vacuum cleaner's head without encountering such problems.

Whether or not you attach the vacuum hose to the farthest corner of the spot, you must determine the distance to the vacuum port or skimmer port.
