How to Choose the Best Pool Cleaner for Fiberglass Pools

Getting a pool cleaner for Above or in-ground pools can be a bit challenging. It is because you need a cleaning device that can clean debris & dirt and comes with enough power to clean it. These cleaners can either be installed into the pump or you can connect to a different socket.

Additionally, you need to consider how your device will clear the collected dirt, leaves, and debris from your pool.

Here are some of the main things that will help you buy the right pool cleaner:

Determine The Vacuum Type You Need

Type of vacuum It is the modern time where you get dozens of options for everything. You can get a different type of cleaner for such types of pools. These are – Robotic, Pressure, and suction pool cleaners.


A robotic pool cleaner is the best choice for pool owners. Just like a regular cleaner, a pool robotic cleaner does not require any assistance in cleaning your pool. All you need is to start the cleaner, and it will take care of the rest.

Usually, these automatic cleaners have tiny motors that clean your pool and a suction part that takes out all the leaves and debris from the pool. If you are looking for something especially for cleaning leaves, then you can consider a good robotic cleaner for leaves. Later on, you can remove the dirt from the device by cleaning or changing its bag.

These are helpful when you have a busy schedule. Additionally, most of these cleaners come with a feature to schedule the pool cleaning at a specific time of the day.


These are the swimming pool cleaners that come with strong suction power. Usually, they come with suction power that is enough to clean all the dirt, leaves, and debris from the pools. You might not find the cleaning brushes in these cleaners.

That is why the cleaning from these cleaners depends solely on the suction feature. If you are looking for an excellent pool cleaner for manual cleaning, then the type is the right choice for you.

Pressure Vacuum Cleaner: 

These are the most interesting types of pool cleaners you will come across. They keep floating in the middle of the water and create pressure with their suction power to keep the water flowing. Additionally, they trap debris and dirt in the process.

That way, all the water goes through the filter, and your pool stays clean for a longer time. These cleaners may require a second pump to maintain the water flow. But, using them could be costlier than the other type of pool cleaners.

Pool Type

You should consider whether you have an above-ground pool or an in-ground pool. Not every vacuum on this list is designed for both pool types. So, pick a pool vacuum that fits your swimming pool type. You can go for the robotic vacuum cleaners without any doubt as both the Dolphin and Polaris work with above-ground and in-ground pools. 

Traction Matters

The fiberglass pool is slippery. So, vacuum cleaners struggle to pick up dirt & debris from the wall or the pool bottom. In this case, Polaris 9550 will be your best trait. It has four wheels that provide better traction and grip to suck away messes from slippery surfaces. 

In addition, some advanced models are equipped with smart mobile apps features, so you can operate them remotely.

Polaris 9550 vs Dolphin premier

Both Polaris 9550 and Dolphin Premier have advanced features to leave your swimming dirt-free. But still, they have some differences, and this chapter will disclose those similarities these robotic vacuums have. 

DC Motor

Dolphin Premier has a 24-volt motor that reduces less energy than other vacuums. It consumes only 180 watts of electricity, which costs only 5 cents per hour of operation. 

On the other hand, the Polaris 9550 Robotic Vacuum comes with a 30-volt DC motor. It requires less energy than the Premier and adds little operating costs to your electric bills. 


The Dolphin Premier features a Smart Navigation system. Due to this technology, this robot scans your entire pool & finds the most efficient cleaning route to deep-clean the pool bottom. 

Therefore, its tangle-free swivel cable allows the robot to travel around your pool without any hang-ups. On top of this, the direct-drive hyper grip tracks avoid slipping when climbing walls. Plus, grippy tracks prevent the robot from sticking with the ladders & drains. 

On the other hand, the Polaris 9550 Robotic Vacuum Cleaner has an ActiveMotion sensor. Because of it, the robot automatically changes its position to cover your entire pool without hang-ups. 

Filtration System

Multimedia is the name of the next-level filtration system. It has three media types- a micro-cartridge, a standard cartridge, and an oversize debris bag. 

This robot can capture fine particles & dirt because of the micro-cartridge. On the other hand, the oversize leaf canister allows you to collect leaves & insects to leave your pool crystal clear. 

In contrast, Polaris also has an advanced filtration system to trap & capture small debris & dust. The best part of Polaris is- it has a dirt canister indicator. So, you can know when it’s time to empty the debris holder. 

Suction & Scrubbing Capabilities

The 24-volt DC motor provides a 4000 suction rate to pick up sticky & stubborn dirt & debris from the pool bottom. Plus, its dual scrubbing brushes help break down the toughest dust and loosen them. Indeed, a single speck of dirt can get no chance to stand on your pool bottom. 

On the other hand, Polaris 9550 has a non-marring blade to tackle the algae & bacteria and get rid of them from the walls. Unlike Dolphin Premier, it comes with a remote control system. With it, you can maneuver this robot to every corner of your swimming pool to spot clean the surface. If you are specially dealing with algae and dirt on your pool, you may consider buying reliable algae and dirt pool cleaner.

Does Muriatic Acid Damage Fiberglass?

Muriatic acid is a harsh chemical. It attacks the fiberglass slowly but damages the surface. If you have a fiberglass pool, we recommend you avoid muriatic acid.

Yes, you can apply muriatic acid to your pool to lower the pH or alkalinity level. Before pouring it into your pool, ensure you dilute it with water. And of course, ensure you keep the skimmer and fixtures away from the muriatic acid.

But the suggestion is to avoid applying muriatic acid in your fiberglass pools. 

What Is The Best Robotic Pool Cleaner For Fiberglass Pool

Undoubtedly, Dolphin Premier is the best robotic vacuum cleaner for fiberglass pools. 

It has SmartNav technology to scan your entire swimming pool. Firstly, it maps out your pool, and then, discovers the most efficient cleaning route to deep-clean the surface. 

The dual scrubbing brush it includes can break down the sticky & stubborn dirt & dust and remove them from your pool. Therefore, it also has a weekly scheduler to clean your pool automatically. 

Besides, you can also consider the following robotic vacuum cleaners for your fiberglass swimming pool.

  • Polaris 9550 Sport Robotic Pool Cleaner
  • Dolphin Nautilus CC Plus
  • Aquabot Pool Rover Junior

Can You Pressure Wash a Fiberglass Pool

Yes, you can pressure wash a fiberglass pool, but you need to be careful during the pressure washing. You should position yourself at least 3 to 4 feet away and use a wide tip nozzle that doesn’t have too much pressure.

You must consider the below points before pressure washing a fiberglass pool:

  • Use an electric pressure washer, as gas power pressure washers are more powerful
  • Choose a low-pressure spray to prevent damage to your fiberglass
  • If you are planning to use soap, you should use a soap pressure washer attachment

During the pressure washing, you should wear safety glasses and masks. Never put your hands or body parts in front of the spray of your pressure washer.

Final words

We find the Polaris 9550 best for your fiberglass pools. Its 4-wheel technology provides superior traction on the slippery surface and allows you to pick up dirt & dust like a champ.

On the other hand, you can go for the XtremepowerUS 75037 Climb Wall Pool Vacuum Cleaner for sucking away fine debris & particles.

Lastly, we recommend you choose the Zodiac G3 if you are looking for an automatic suction-side cleaner.
