How do you vacuum a fiberglass pool?

You cannot use metallic vacuum cleaners or similar harsh material equipment for cleaning the pool. The metal parts will damage your get coat finish and the fiberglass will be ruined. Things like crushes and steel wool also must not be used.

The fiberglass pool vacuum mostly has something that improves their movement, like wheels with tires for better adherence and similar. Some are equipped with soft brushes suitable for this kind of material. If you have a challenging pool, like a lot of steps or objects on the surface, then keep in mind these kinds of gadgets would facilitate the cleaning.

One thing is for sure, the cleaner will release you within a time spent cleaning the pool.  Although some of them need guidance and supervision, you won’t have to clean debris manually and pick up falling leaves and twigs in your pool.  Instead, you will have more time to swim and rest.

  1. Never underestimate how vigorous vacuuming your fiberglass pool can be. It is quite difficult than skim cleaning a regular pool, so you should be adequately ready. Make sure to take breaks after a while.
  2. Begin by vacuuming by the shallow end of your pool, working towards the deep end using long strokes. If any sediment is, ensure to come back and clean it again. Overlap your vacuum stokes always, to ensure you don’t miss any sediment.
  3. Take your time and patiently vacuum your fiberglass pool to avoid mistakes. Remember this is not a skim cleaning, you don’t need to rush! This is because moving the head of your vacuum too fast may scatter any sediment resting underneath your pool thereby making the pool water cloudy.
  4. If the pool water does become very cloudy due to the disturbed sediment, then take an hour or two break to allow the sediment to settle. , return and continue vacuuming.
  5. Finish the vacuum stokes at the deep end of your fiberglass pool. You can adjust your telescopic height where necessary.

Now that you are done vacuuming your fiberglass pool, it’s also very important that you clean your vacuum.

To do this, unscrew the vacuum’s head and drain any excess water accumulated during the pool cleaning exercise.

After cleaning the vacuum, replace the head with a brush. Then use the brush to scrub down the surface of your fiberglass pool.

Scrub any blemishes caused by organic dirt or debris available.

What to Look for in a Pool Cleaner

  1. Type

When looking for the best pool cleaner for your pool, you will come across three different types of pool cleaners. Suction, pressure side, and robotic are the three types of pool cleaners, each having its advantages and disadvantages.

Suction pool cleaners are the most affordable, however, it takes more effort to operate when compared to other types. It uses your pool’s pump to clean out debris by suctioning it with a long hose connected to the skimmer.

It cleans randomly, unlike the robotic model that plans out an optimal path for itself. Electric bill costs also add up because of its use of your pump system. So, while you might decide to cut off some expenses while purchasing this model, you’re also spending as much on electric bills.

Pressure pools on the other hand are moderately priced, although it still makes use of your pool’s pump and filter. It also increases your electric bill costs. The main difference between a suction cleaner and a pressure cleaner is that the latter uses a booster pump to increase pressure.

As pressure is added to the water, it powers the wheels of the pressure pool cleaner to clean out the pool. These types of cleaners cone along with a bag which can be emptied.

Robotic pool cleaners are the most expensive. If you’re on a tight budget, the robotic cleaner probably isn’t the right choice for you. However, it takes less effort to clean your pool and lengthens the durability of your pool’s filter. It doesn’t need any pump or circulating system to operate because it uses the software.

  1. Automatic vs. manual

There are manual and automatic models of pool cleaners. Robotic pool cleaners are usually automatic, although some pressure and suction pool cleaners can be automatic as well. However, robotic models have better coverage. Automatic pool cleaners clean your pools unsupervised, scrubbing the floor and walls of your pool.

Different pool cleaners have different cleaning coverage. Some of them are built to clean only the floor of pools, while some can clean the floor and walls. Some special models can clean the stairs, waterline, and covers. If your pool has tight corners, you should go for a pool cleaner that can reach those corners.

  1. Traction

Fiberglass pools have the advantage of having less grime because the floors are less porous than concrete pools. However, this comes at a disadvantage because it becomes harder for pool cleaners to gain traction on them.

The Polaris F9550 on the list is one of the best pool cleaners with good traction.

  1. Big debris vs. small

For fiberglass pools located under trees, it is only normal to find leaves and branches littered in your pool. You might want to go for a pool cleaner that can effectively clean large debris than one that is better suited for smaller debris. Pool cleaners that exchange bags for filters can also be a good alternative.

The pool vacuum moves throughout the pool’s floor and walls, cleaning up debris by suctioning it through the hoses, and sending it to the skimmer or the vacuum line, if available.

Different pool vacuums have their own way of functioning. While some may follow a random part while cleaning, some other pool cleaners will use a mapped-out route.

How Long do Pool Cleaners Last?

Just like any other equipment, how you maintain and store it is a factor to how long it lasts. If it is continuously exposed to chlorine and harmful chemicals, its durability will be shortened. Most manufacturers advise their buyers to remove the unit from the pool after a successful pool cleaning.

You can use your pool cleaner for at least five or more years if you replace some essential parts.
