How to clean a pool: all the keys for efficient maintenance


For those who have never faced cleaning a pool, but also for those who have been doing it for years … but not quite well. Investing a minimum of time in ensuring that the pool is in optimal condition is essential, but that time needs to be of quality, effective.

Cleanliness makes the bath appealing and ensures the well-being of bathers, so don’t forget to get to work. If you don’t know how or want to go over the procedures, read our guide.

How to clean a pool – step by step

It may look like a lot of steps and accessories, but when you’ve done it several times, the process will go smoothly and it won’t involve any extra effort. Just remember that regularity is a value, so the higher the frequency (and the quality of the time spent), the less cleaning time you need.

The ideal is to follow these steps at least once a week, but it will depend on the frequency of use of the pool, the time of year, etc. Anyway, the steps we propose are general, since not all the pools are the same (different materials, dimensions, uses…), nor are the washers the same. If you have a robot, it will be enough for you to start it up according to the manufacturer’s instructions, and let it move around the pool for a few hours.

Before you start, check that the float line is at least halfway through the skimmer.

Collect waste from the surface

Use the basket with a telescopic handle that bring lots of cleaning kits, or that you can buy separately. Pass it gently on the surface of the pool, until you remove the insects, leaves and other elements on the waterline.

Try to collect also those visible remains that are not on the surface, but that you see suspended in the glass. They can cause the vacuum cleaner or suction pump to jam.

Clean the skimmer or skimmers basket

Collect dirt that may have been left inside, using your own hands or a pressure jet of water. Remember to wear gloves, if any, because there may still be live insects, such as wasps, that can harm you.

Remove protection in vacuum and vacuum nozzles

The nozzles usually have a protective cap to prevent accidents, especially with children, but it should be removed during cleaning.

If it’s the first time, use it to identify which connectors or adapters are good. The measurements are usually universal and, in addition, the kits usually bring a set of two or more connectors.

Connect the hose to the vacuum cleaner

It usually has a flexible and fixed end. It is the flexible one that you must connect to the vacuum cleaner so that it has sufficient mobility within the pool.

Dip the hose and the cleaning in the pool

This step, which seems simple, also has its trick, because the pump must be prevented from being filled with air. Help yourself with the pole, so that you introduce it parallel to the hose, using both hands.

When the hose cleaner is already on the ground, insert whatever is left of the hose, slowly. When you finish, check that the water mirror (the water line inside the hose itself) is at the end height, well visible.

Connect the hose to the suction socket

An end would be placed on the wall cleaner itself, a step already completed before. The other one, to the suction shot.

Connect the pump

Place the position valve in the filtration position, and start the pump.

Breathe in the pool floor

Breathe in the floor with more or less rhythm, depending on the dirt you see there is, and drawing imaginary lines straight and parallel across the background, one after the other. It depends on the length of the pool, but if you sit on one of its shorter sides and move the pole all along, your body will have to move less.

Brush floor and walls

The suction force is not always sufficient to remove the dirt and end up in the filter, so after vacuuming, it is recommended to brush. Before proceeding, remember to place the protective caps on the nozzles you have opened for aspiration.

The brush should be equipped with a pole, which you should grasp well, and which will help you to exert the necessary pressure on brushing against walls and floor. The activity requires a minimum of exercise because you must bend your knees, as if you were doing squats, to carry the brush from the float line to the bottom, in the case of the walls.

Do not hesitate to brush well walls and floors for fear of clouding the pool, as the effect of not doing so will be worse: algae may appear.

Complementary actions

Before suction, you can pour a flocculant or clarifier fluid, as directed by the manufacturer. The usual thing is that you can use both a dosing pump and put it directly in the pool, previously diluted in water.

Also, when you finish, check that the filter sands do not exceed 1.3 kg per square centimeter. If so, you must place the selector valve in Wash, and open the sinkhole and return valve. Check the manometer to see if this step is essential or you can postpone it.

How to clean the background

In this section, we will establish differences by pool type, because each will require specific treatment.

Swimming pools with filtration system

With cleaner manual: It travels all over the surface of the soil doing slow movements, especially if you have poured flocculant fluid before proceeding. If you go slow, you’ll keep the dustpan from removing the dirt, instead of catching it.

With robot cleaner: Connect the wall cleaner according to the model’s instructions, and immerse it carefully in the pool so that it, autonomously, moves through walls and bottoms.

Pools without filtration system

There are pool vacuum cleaners that are plugged into an electrical outlet, and others that are loaded before so as not to have to stay plugged in. Depending on the size of the pool, you can use a coupled telescopic handle or the handle with which they are equipped.

Use the method you use, follow the principles already mentioned: vacuum the entire background by drawing parallel imaginary lines, gently, to remove all dirt.

How to keep it clean during the summer

Do not stop doing any of the following tasks, which do not have to carry a specific order.

Adjust pH

Remember that it must be between 7.2 and 7.6, a value that you will be able to know using the pH and chlorine tests, several times a week.

Disinfect water

Even if you use the mango basket to collect dirt from the water and cleansers, microorganisms such as bacteria, which are not seen, can put bathers ‘ health at risk. In the chemical treatment of water the star is chlorine, the residual of which must be 0.5 and 1.0 ppm in the water. Use the meter to find out, and keep the water from getting clouded or the dreaded algae show up.

Again, it uses chlorine and pH tests assiduously to know the levels. You can use several formats, such as tablets, saline electrolysis devices, or active oxygen.

Preventing algae

Heat and solar radiation favor their appearance, so in summer, it is recommended that you use antialgae, along with chlorine. Use the product at least once a week.

Clarify water

To use the flocculant, follow the manufacturer’s instructions and advice. You can pour the required dose and connect the scrubber for about an hour and then leave the water to rest. Do it better at night, so as not to hinder the bathroom.

The suspended particles will be placed at the bottom, so then you have to pass the dusting.

Clean filters

Every day, or at least every two or three days, you should look at the filters because, if they are very full, they can affect the pool water. You must perform counter-checks, putting the selector valve in the appropriate place, and opening the required valves. You must also disinfect the sand, which does not require much frequency, as we explained above.

Don’t forget to remove the dirt from the skimmer basket, using gloves and water, or shaking it on the floor and then removing the dirt.

Do I have to do anything if I’m not using it?

When the weather conditions are adverse and the vacation ends, the pool falls into disuse, but that does not mean you should not take care of it. In fact, the action of bathers is the least, especially if they usually go through the shower before getting into the water.

You will need a winning product for swimming pools and shock chlorine , as well as, in addition, a protective blanket and a filter solids descaler . Follow these steps.

Clean the pool

Pass the pool cleaner and brush the walls, but also check the basket of the skimmers and the pump pre-filter.

Check the pH

Use the test to find out if it is between 7.2 and 7.4.

Comes to shock chlorination

Use the right product for it.

Doses winterizing products

The use you make of liquid or floating greenhouses will depend on the material with which the pool is made.

We recommend connecting the purification equipment a few minutes a day, or every two or three days, not with the intention of cleaning the pool, but to avoid humidity in the electrical equipment. Also that you install a protective blanket against the particles that the wind brings in suspension, which will also serve as a safety element.

Possible problems we can find and solutions

Some of the most common problems in swimming pool maintenance are those listed below, with your solution:

Cloudy water

There are small particles in the water that are difficult to filter, or that chlorine cannot oxidize. It may be due to algae, high pH, or insufficient filtration.

Solution (s): check the filters and clean them (if applicable), use flocculant fluid or pH regulation products.


You will notice that they are if the pool, as in the previous case, is cloudy, if floors and walls are slippery, if filters are clogged or if water demands a lot of chemical treatment. They are more frequent in summer, due to environmental conditions.

Solution: for green, yellow or black algae, there are specific algaicides. Adjust the pH, use chlorine and flocculant, and filter for 24 hours or until the water is clean. Then brush walls and soil, use algaecides to prevent.

Eye and skin irritation

Bathers will notice itching and itching in the eyes and parts of the skin, the most common cause of which is an imbalance between PH and chlorine.

Solution: adjust the pH, allow a few hours to the next measurement and, as the case may be, perform a shock treatment or chlorine neutralizer.

Water of another color

If it’s green, it can be algae, follow the steps above. If it is blue, brown, or black, in addition to algae, there may be an excess of copper, iron, or manganese.

Solution: again, you will have to adjust the pH and use a shock treatment, based on granulated dichloro and flocculant. It then filters for at least 24 hours and finally brushes and sucks.

Presence of lime

The track is given to you by the stains on walls that, if rough, will become rough.

Solution: the pH level may be too high, so you will have to lower it, using the right product for it.

Oxidized metals

If scaleless or other elements are oxidized, the pH or calcium hardness may be low.

Solution: adjusts the pH with the right product or increases hardness, which also requires a specific product.


They can be the result of chemical elements worn by bathers, such as shampoo or sun creams.

Solution: since they usually stay on the surface, pour a flocculant, let it act and then breathe in.

Excess chlorine

In this case, you’ll notice by the smell, by irritation.

Solution: measures chlorine levels and, if high, lets a few hours pass before the next test, performs a shock treatment or, if necessary, a clor neutralizer.
