How To Bring Your Pool Back Online After A Flood

Dirty swimming pool after a flood.

Bringing your pool back to a usable condition after a flood can seem a daunting task, but it is essential to do so before you use it.

What needs to be done will depend on the extent of the flooding and may mean no more than testing your water and making some adjustments to the chemicals in your pool or may be a major undertaking involving the replacement of your pump or other equipment.

Here is a brief rundown of some of the things you should do to get your pool up and running again.

The first thing you need to check is the safety of the pool and it’s surrounds and your pool equipment

  • Check to make sure your pool fence is still sound and meets the requirements. This is particularly important if children have access to the general area. Please ensure the gate is fully functional and still closes automatically. Make sure the surrounds/deck areas have been cleaned of any debris and tools If needed, scrub and hose down to get rid of any mud or slippery build-up.

  • No matter what the extent of the flooding, it is essential that you check the electricity supply to your pool area. This is especially the case if the area and equipment was inundated and under water. If the breaker switch on your circuit board has ‘tripped’, it would be prudent to get a licensed electrician to check the circuits for you. The electrician will also be able to check your pump and other electrical equipment to ensure they still work or have been damaged and need replacing.

  • Whilst checking the safety of your pool, also check the shell of the pool itself to see if it has been damaged and needs repairs. If needed, make the appropriate arrangements with a pool technician or pool builder. Also check your pool tools to see if they are damaged and need replacing. Check the skimmer and basket as well.

  • Now to start on the water. There will be numerous contaminants in your pool water so it would be a good idea to ‘shock’ your pool using a shock agent or hypochlorite. Be sure to follow the instructions on the label.

  • If your water turns clear or is only slightly cloudy, test your water and adjust the chemistry to get it into balance. The water will have phosphates in it. Phosphates are the result of organic matter breaking down and can lead to the water becoming cloudy.

    The first step is to get rid of the phosphates by adding a phosphate remover as directed. This will normally make the water even more cloudy You can treat this by adding a clarifier as per the directions. Follow the instructions on vacuuming to waste if needed.
  • If your water is full of large debris, remove by hand or scoop it out using a net.

  • If the water has mud or other debris in suspension, you will need to floc the pool. Please ensure you follow the instructions on how to use the Flocculant, these are detailed on the packaging.

  • For the best results of flocculant, the pH of the pool water should be 8.2. Use Soda Ash to raise pH levels if required
Zodiac Ph Up (Soda Ash) 2Kg.
  • After the sediment has settled, you will need to vacuum the waste. If you have a cartridge filter, remove the filter element. Make sure your pool has sufficient water in it as you will be pumping a large amount of water to waste.

  • You may need to repeat this process if not all debris in suspension was removed.

  • If the water ends up with a touch of green, it could be for two reasons.

    It could be that you have a touch of green algae, and this can be tackled by adding an algaecide as per directions. If you used an algaecide previously, it may contain copper, and this can oxidize in the water and turn it green. This can be fixed by adding an appropriate metal remover according to directions.

    If you used an algaecide previously, it may contain copper, and this can oxidize in the water and turn it green. This can be fixed by adding an appropriate metal remover according to directions.

  • You may need to repeat some of these steps to get the water clear.

  • Test your water again and make any appropriate adjustments to the chemistry.

  • It is essential you keep a close eye on your pool over the next few weeks. Keep a close eye on what the water looks like, test the water on a regular basis and take appropriate action as soon as you can to fix any anomalies.

The Benefits Of Swimming Pool Covers

Swimming Pool Cover

When you own a swimming pool, it’s likely that you will need a swimming pool cover. Pool covers come with many different benefits, and there are a few different types of swimming pool covers as well.

Before you decide on the right swimming pool cover for your needs, it’s important to have all the information. Let’s look at what a swimming pool cover is, the different types of covers, and the benefits you gain from a swimming pool cover.

What is a Swimming Pool Cover?

Swimming pool covers are often called solar pool covers or solar pool blankets. Pool covers are made of different types of materials and are used to cover the water. Each type of swimming pool cover has a specific use.

Common types of Pool Covers

There are several types of pool covers to consider for your inground or above-ground swimming pool. A solar pool cover and a winter pool cover are two of the most common options.

Solar Pool Cover:

Solar Pool Cover

Some call the solar pool cover a pool blanket because it helps to keep the pool water warmer. A solar cover is like a very large, heavy-duty sheet of bubble wrap. It acts as insulation for your pool water to help lock in the heat and keep the water from evaporating.

Solar pool covers are an affordable way to keep your water warmer during swimming pool season. They are easy to put on the pool and take off. They float above the water and they cannot support any weight.

Winter Pool Cover:

Winter Pool Cover

A winter pool cover is used for both an above-ground and an inground swimming pool. It’s like a very large, heavy-duty tarp. The cover will sit on the top of the pool water and it’s secured by tie-down toggles.

This type of pool cover offers a way to keep out the debris throughout the winter. They cannot support much weight and you may need to empty out excess water from the cover from time to time.

Winter pool covers are the most affordable option to use during the off-season and they are very easy to install.

Safety Pool Covers:

Safety Mesh Pool Covers

There are a few different types of safety pool covers you can use. These are often used for inground swimming pools and these covers can support weight. Some of the common safety pool covers include:

Mesh Safety Pool Covers – A very lightweight option that traps debris, but lets water through, this safety cover can support large amounts of weight.

Solid Safety Pool Covers – This pool cover will keep even ultra-fine debris out of the water and provides UV protection.

Hybrid Safety Pool Covers – A mixture of a solid and a mesh safety cover, this option will drain like a mesh cover, but provide the UV protection of a solid cover. It can also support large amounts of weight.

These safety covers provide a better option in the winter compared to a basic winter pool cover. Since these covers can support weight, you won’t have to worry about an animal or person falling into the cover.

Automatic Pool Covers:

An automatic safety pool cover is the most expensive option, but it also offers the best choice for your luxury swimming pool. It’s super easy to apply and remove with no need for water bags, anchors, or lifting. Simply press a button and the cover will unroll or retract.

It’s also possible to find automatic solar covers. When you choose an automatic cover, you gain the best option for convenience, but it will come at a higher cost.

7 Main Benefits Of Using A Swimming Pool Cover

Pool Cover

1. Saves You Money

When you have a swimming pool cover or a pool blanket, you’ll actually save money on your pool expenses. A solar cover can help keep the water warmer, which can save you from running your pool heater as often.

You can also keep your pool free of bugs, debris, and dirt easier with a swimming pool cover.

While some pool owners may only use their swimming pool cover during the colder months, you can save money by using a cover year-round. Pool covers are one of the most important accessories for your swimming pool.

2. Helps Reduce Water Usage

One of the benefits of a solar pool cover is less water evaporation. You won’t lose as much water from your pool when using this type of cover during the hotter months of the year. This saves you from having to pay to add water to your pool.

Pool covers can actually help reduce your evaporation by about 95%.

Since a pool cover will help keep your pool cleaner, you won’t have to backwash your filter as often, either. Every single time you do the backwashing, you will use up water. By reducing the number of times you have to do this, you can save on your water bill.

3. Keeps The Heat In The Pool Water

One of the biggest benefits of a solar pool cover is the ability to keep heat in the water. Nobody wants to swim in a cold pool. With a good solar pool cover, you can keep the water temperature from dropping as much overnight.

With a translucent pool cover, you can even get more sunlight and heat into the pool. This can help to heat up the water during the day and make it more comfortable for swimming. Of course, you will also save money by not having to run your swimming pool heater as often.

4. Extend Your Swimming Season

You get a longer swimming season with a swimming pool cover. Using a pool blanket allows you to keep the water warmer for a longer amount of time. Maybe you don’t have a pool heater, but you want to extend the swimming season.

When you use a pool cover, you can extend your season into the autumn and the spring months. It can actually help you use the sun to increase the pool temperature by up to 8 degrees Celsius, depending on your location.

5. Avoid Water Flow Blockages

When you get too much debris in your pool, it can lead to a water flow blockage. With the right swimming pool cover, you can keep that debris out of your pool and reduce the chance of a water flow blockage happening.

If this type of blockage happens, it puts an extra load on your swimming pool pump. They reduce the efficiency of your chlorinator and filter, which also leads to water of poorer quality.

6. Spend Less Time On Pool Maintenance

When you use a solar pool cover and other types of swimming pool covers, you can spend less time on maintenance. Using pool covers will help you to have more time to use your actual pool.

A pool cover keeps the debris out of your pool. This means less time is needed to vacuum the pool, skim the pool, and clean out the filter. You won’t need to spend nearly as much time doing pool maintenance when you use a swimming pool cover properly.

7. Use Chemicals Less

Pool chemicals provide a way to restore your pool water to a healthy state. After the rain, debris, or leaves get into your pool, it can cause the water to become imbalanced. With a pool cover to protect your swimming pool water, you won’t need to use chemicals as often.

A solar pool cover will keep your swimming pool clean of debris. You won’t have to worry about debris or even as much rainwater getting in and causing issues.

Since you will likely use chlorine in your water, reducing the use of chlorine can also happen with a swimming pool cover.

Chlorine becomes less effective due to UV light. With a pool cover, you can reduce the amount of UV impacting your chlorine, which can help keep you from using nearly as much.

Disadvantages of Using a Pool Cover

Winter Leaf And Debris Mesh Pool Cover

While using a pool cover comes with a ton of benefits, there are a few disadvantages. Before you decide which type of pool cover is right for you, it’s important to know about the disadvantages, too.

Some of the common disadvantages of using pool covers include:

Looks Ugly – Some pool owners think solar pool covers look ugly. However, you can get a transparent cover to solve this issue.

Hassle To Use – It can feel like a hassle to use a swimming pool cover. Instead of jumping in for a quick swim, you have to take off the cover. Automatic covers might help to solve this issue.

Difficult For Irregular Shaped Pools – You might have an irregular-shaped pool, which makes it harder to use a solar pool cover. If it’s not a rectangular pool, it can be harder to put on a cover or use a roller. However, there are customised swimming pool covers that you can use.

A Roller Is Required – It might be hard to find the right space for a roller for your swimming pool cover. However, many pool owners can have a roller installed on a nearby fence or at the end of a swimming pool.

Might Increase Salt Consumption – If you have a saltwater pool, you might use more salt when you use a solar pool cover.

While there are a few disadvantages to using a solar pool cover or any type of pool cover, they are one of the best accessories for your pool. 

You’ll get protection and the ability to gain many benefits that often outweigh the disadvantages. Plus, with the right pool cover you can eliminate most of the disadvantages on this list.

How To Install Your New Solar Pool Cover

When you first get your solar pool cover, you might be a bit overwhelmed by it. Unpacking a pool blanket can seem a bit stressful as it will be rather large. Simply follow these steps to install your new solar pool cover:

1. Unfold the cover near the pool with the bubble-side down on top of the water.

2. Use multi-purpose scissors to trim your cover to fit your specific swimming pool shape. It’s best to leave about 2 inches on each side of the pool, both longer and wider.

3. Make sure to leave a two- or three-inch flap by your skimmer so you can tuck the cover under the edge of the skimmer.

It’s important to note, the pool cover may shrink for the first six to eight weeks in the heat. If you cut the cover to the exact size, you will end up with a gap. This is the reason you want to leave a few inches of extra cover.

How To Properly Use A Solar Pool Cover

It’s a rather big chore to put your cover on and take it off every single time you want to use your swimming pool. However, if you have a reel, you can make it easier and more convenient.

You can put a pool cover roller at one end of the pool and attach it to the solar blanket. Then, just turn the wheel or handle to roll up the solar pool cover.

It’s even possible to get a pool blanket with wheels. If this is the case, you may be able to move the reel out of the way, once you have taken the pool cover off the pool.

A Few Helpful Tips To Remember With Solar Pool Covers

You want to remove the solar cover before you swim, every single time. If someone gets stuck under the cover, it can be very dangerous. Make sure to completely remove the cover so you can enjoy swimming without issue.

If you have a salt chlorinator, the chlorine gas can also build up under the cover, if the pool isn’t used for a longer amount of time. This may happen more often in the winter months when you’re not using your pool as much, as well. It’s a good idea to remove the cover every so often in the winter to allow the chlorine gas to escape from the pool.

Frequently Asked Questions About Solar Pool Covers

Should I put my solar pool cover bubbles up or down?

You want to put your solar pool cover with the bubbles facing downward onto the water. This allows the sun’s heat to be trapped in the bubbles and help make the water warmer. The heat will be transferred into the water.

When you place the bubbles up, the pool blanket will end up damaged and will deteriorate. It will also not work properly and won’t help to heat your pool from the sun.

Is it a good idea to leave my solar pool cover on during the day?

You will get the best results from using a solar pool cover whenever you’re not using the swimming pool. The daytime will help you gain the most heat from the sun with your pool blanket. It will also keep the debris out of your pool when you’re not using it.

At night, the solar cover will help insulate your swimming pool. It will keep the heat from escaping as fast. Use your solar pool cover whenever you’re not using the swimming pool for best results.

How long will my solar pool cover last?

Your solar pool cover will deteriorate over time due to high levels of chlorine and the heat from the sun. If you have a large amount of chlorine in your pool, it can cause the lifespan of your cover to be less compared to a pool with less chlorine.

Commonly, bubble covers will last between five and ten years. If you have a 300-microns cover, it will give you about five years of time. A 500-micron cover will last about eight to ten years.

How do I keep my solar pool cover from blowing off my pool?

If you have a well-fitted pool cover, you should not have to worry about it blowing off in the wind. When the edges are all on the water and not above the edge of the pool, you won’t have much to worry about with the wind.

The wind will actually push down onto your pool cover, which will help to keep it in place. However, if your pool blanket is too large and extends past the edge of the pool, it could be taken by the wind. Cutting your solar pool cover to fit your pool perfectly will ensure you don’t have to worry about it blowing off.

Make sure there are no gaps between the edge of the swimming pool and your solar cover. You want to make sure the wind cannot get down and underneath your pool blankets. If your solar cover fits well, you won’t have to worry about the wind.

When you have a swimming pool, you need the right cover for your pool. Most pool owners will need a solar cover and some type of special cover for the winter. Make sure you get the right swimming pool covers to protect your pool year-round.

How To Look After Your Salt Chlorinator Cell

Salt Chlorinator Cells

Although the cells provided by Best Pool Supplies are manufactured from high-quality materials with longevity in mind, over time the electrolysis will wear out the cell coating which will result in the electrodes stopping producing chlorine.

Here are some handy hints that help you to prolong the life span of your salt chlorinator cell:

  • Don’t overwork your salt cell – running the chlorinator at 100% output or longer than 8 hours a day will shorten its life.
  • Use Conditioner or Stabilizer to protect your chlorine from breaking up in the UV of the sun which will again prevent overworking your salt cell.
  • Keep proper pH balance. PH level below 7.2 will etch the salt cell, and if above 7.6 will reduce the chlorine’s effectiveness. To reduce the PH use pool acid or dry acid and raise the PH using soda ash.
  • Maintain proper salt level in the pool. Low salt levels will destroy the coating of the electrodes and high salt levels will overload the chlorinator.
  • Inspect the cell regularly and once you notice scale build-up on the electrodes clean it with an appropriate Salt Cell Cleaner.

Calcium deposit (formation of scale) is one of the main reasons for premature failure of the chlorinator electrode. The scale on the electrodes will reduce the chlorine production, restrict the flow of the water, and if not addressed it will put an unnecessary strain not only on the cell but also on the powerpack and can cause damage to both.

It is important to check the cell and clean the electrodes from the scale when it becomes necessary. How quickly calcium builds up on electrode(s) varies from pool to pool and depends on various factors:

  • Your geographic location – areas with hard water and when bore water is used the scale forms quite quickly.
  • The pool finish – calcium from the pool plaster (concrete pools) or grouts (tiled pools) can raise the calcium levels of the pool water.
  • Pool chemicals – super chlorinating with calcium hypochlorite affect pool water calcium content.
  • Unbalanced PH level of the water plays role in calcium build-up on the electrodes.
  • Incorrect salt level.

If your chlorinator is non-self-cleaning (does not reverse polarity) it is advisable to check the cell once a week (even more often during summer months). If the milky white substance starts to appear on the electrode(s) you know it is time to give the cell a clean.

These days most new chlorinators on the market are self-cleaning. These units avoid scale build-up on the electrodes by reversing the polarity between the electrodes, repelling mineral deposits, which are washed away by the pool water rushing through the cell housing before they can attach to the oppositely charged electrode.

Even if the chlorinator is self-cleaning, the cell still needs to be cleaned roughly once every 6 months (more often in hard water areas). Many of these intelligent units advise you when it is time to clean the cell and warn about the low salt level in the pool water as well.

To clean the salt chlorinator cell:

Switch off the chlorinator and remove the cell from the housing following manufacturer instructions.

  • If the scale layer is not very heavy the deposits can be washed away with a garden hose. (NB! Do not brush the electrodes or scrape with sharp objects.)
  • If the above does not help, it is needed to soak the cell in a suitable cleaning solution like Salt Chlorinator Cleaner or self-mixed acid solution. To prepare acid solution mix 1 part of Pool Acid (Hydrochloric Acid) with 5 parts of water in the bucket. Submerge the cell into the solution for 3-5 minutes. If it takes longer than 5 minutes to clean the cell it is an indication that the electrodes should be cleaned more frequently.
  • Put the cell back into cell housing.

NB! Always take extra care when handling chemicals and store them out of the reach of children.

How To Clean Your Pool Filter Cartridge In Six Easy Steps

Pool Filter Cartridge

Clean Your Pool Filter Cartridge

With a little bit of elbow grease, you could prolong the lifespan of your pool filter cartridge using this guide. Without minimal maintenance, your pool cartridge will develop a blockage in the element and strain your pump, reducing its lifespan.

But don’t worry, looking after your cartridge filter element is easy if you follow this step-by-step guide.

When should I clean my pool filter cartridge?

Like a car, you can get away with not maintaining your filter for a while, but eventually, it will catch up with you. One day, you might find your filter has stopped working and your water has gone filthy, forcing you to buy a replacement.

Therefore, we recommend cleaning your filter element every two weeks or a fortnight. If you want to throw caution to the wind when it comes to maintenance, then make sure you at least take action after the following scenarios:

After a party/gathering

When friends or family visit to enjoy your pool, your cartridge will be working overtime to keep conditions clean and safe. However, this also means excessive debris will be trapped, building up and affecting future use.

After algae treatment

As a pool owner, you will likely have to treat algae build up at least once in your lifetime. Typically, you will need a chemical like Zodiac Pool Algaecide to brush the algae away.

Some people don’t realise that the algae debris is being sucked into the pool filtration system and clogging up your element. For this reason, it is vital that you clean your cartridge as your final algae treatment job.

After excess operation pressure

Have a look at your filter canister housing and take note of the PSI. Now consult your filter owners manual for the regular operation pressure. If the PSI is 8 PSI above the normal operating pressure, you will need to clean your cartridge. Why? Because the filter element is blocked and increasing the water pressure in your set-up. Instead of manually checking for build-up constantly, this little trick will save you time and energy.

How to clean your filter

  1. Turn off your pump. For safety reasons, if you are using an automated system, turn off your pool at the mains power. If the pump suddenly turns on while your fingers are inside the filter component, you could get hurt. 
  2. Remove the filter element. This is located inside the filter housing – check the product manual for specific guidelines. 
  3. Clean the debris. Don’t rush this step – thoroughly rinse the filter inside and out between the pleats with a garden hose. Products like the Water Wand(see below) save time by cleaning between the crevasses of eight pleats at a time.
  4. Blow-dry the element. Once the element is dry, use compressed air to remove small dirt particles.
  5. Degrease. This step is the premium “car wash” option and is not necessary unless you want optimal performance from your pool filter. If you choose to use a degreaser every time you clean your cartridge, you will guarantee your filters effectiveness and lifespan. Soaking the cartridge in an approved cleaning solution will remove body fats, sunscreen, and other oils.
  6. Reassemble. Now that your filter components are nice and shiny, it’s time to return them inside the filter tank. This may require reassembling any attachments you previously dismantled. Firmly set the top portion of the filter tank back into place and tightly close the clamping mechanism. Turn the air release valve back to the closed position and turn on the pump to ensure the normal functioning of your pool filtration system. Bonus points – apply a silicon-based lubricant around the clamping mechanism to extend its life.

What to NOT to do while cleaning your cartridge

Dont use a stiff brush. Cleaning pleats with a hard material may permanently damage them. Use a soft-bristle or a purpose-made brush designed to gently remove debris found in the material folds.

Dont use a power washer. Filter cartridges are often made of paper or a fine material and are therefore sensitive. The intensity of a power washer can quickly erode the mesh material down, reducing its effectiveness. 

Don’t expect a white mesh. The most important sign of a clean filter is the absence of debris or excessive build-up that can block the filter system. Some discolouration is natural and it is unlikely you will achieve that factory white colour without buying a brand new filter cartridge.

How do I know when it is time to replace the filter element?

As we mentioned previously, filter elements are made from thin materials to catch fine debris. Therefore, they cannot last forever. The shelf life for a standard filter in a pool or spa is between 6 – 8 months. For this reason, we recommend replacing your filter element at least once a year. 

A good sign that your filter cartridge element is ready for replacement is when your operating pressure does not drop after cleaning the filter (see six easy steps above). This is because your filter has become too obscured to be effective, even when cleaned. 

If you heed the warning, you will begin to find excessive debris and cloudy or dirty pool water. Not very nice, especially if guests are visiting. The longer you go without replacing your filter element, the more contaminated water will be allowed to pass through your filtration system. So don’t keep your filter cartridges forever. 

Bonus points you have already opened up your filter assembly for a clean, why not do a visual inspection on the whole unit while you’re at it? Even small tears can be disastrous for water filtration efficiency. So, check for cracks in the plastic housing, tears in the pleats, or other signs of damage. Contact your manufacturers documentation for warranty information and a support phone number.

Salt Chlorinators And Chlorine Levels In The Pool Water

We get many inquiries from the pool owners about the chlorine levels in their pool after they install a new chlorinator or replacement cell. It is not uncommon to have different chlorine levels at different water tests. So what determines the chlorine levels in the pool and why can the chlorine levels be different when there is no change in the setup?

Salt levels: It is quite obvious that we need to have a proper salt level for the chlorinator to operate. If you have changed the chlorinator make sure that the salt levels are adjusted to the new unit. Different brands and models of salt chlorinators often work at different salinity levels.

Phosphates:  If the phosphate levels are high (together with warm weather and high pool use) the chlorine might be used up by fighting algae at the rate it is produced by the chlorinator. The pool does not have to be green. Phosphates are food that stimulates algae growth. The result is that you can be left with less than the desirable amount of chlorine in your pool. In other words – the algae are killed by produced chlorine but there is not much chlorine left afterward. Recommended phosphate levels in the pool water are below 200 ppb.

Stabiliser: The chlorine gets broken down fast by UV. The way to stop this is to use stabiliser which acts as a sunscreen for the pool water. Recommended stabiliser levels are 30 -50 ppm.

PH: Chlorine is more effective when the PH is low. For obvious reasons, we can not have the pool water lower than neutral, as low PH will be corrosive to equipment and cause skin irritation. The closer we keep PH levels to neutral the better chlorine disinfection we will get. For example, at 7.4 (neutral PH) chlorine is roughly 50% effective and at 8.0 it is only about 20% effective (see chart below). Meaning –  the higher the PH the more chlorine is being used in sanitation process and less of it is left in the water.



Testing time: The chlorine readings in your pool water differ depending on the testing time.  For example, if you collected the test water in the morning when the chlorinator just stopped working the chlorine reading will be considerably higher than if you take the sample in the afternoon when the pool has been exposed to UV and bathers all day and all the chlorine has already been used before the chlorinator starts working again in the evening.

Test accuracy: If you test chlorine yourself at home make sure that the reagents are not expired and that they have been kept in dry cool place out of sunlight. Expired reagents can cause incorrect chlorine readings.

To determine whether the chlorinator works properly make sure that the salt levels are correct, balance total alkalinity and PH and assure that the phosphate levels are below 200 ppb. Then run the chlorinator overnight at 100% output and take the water sample in the morning. If you still read low or no chlorine levels, then there most likely is a problem with your chlorinator or the electrolytic cell.

  • To make it more ergonomic, Zodiac has embedded it with a filter full indicator that blinks as soon as the canister inside gets optimally loaded with dirt deposits.
  • In order to make it an intelligently independent cleaner, the manufacturers have automated the pool shape settings so that it adapts itself to its playground without manual commandments.
  • Finally error indicators send up messages on the display if any functional misplay has occurred that needs attention.
  • This ultimate pool cleaner can be operated from distance within a range with the help of its kinetic remote control. You can simply sit by the pool and have the machine working on your command just by the click of a switch.
  • The filter canister of V4 4WD can be dislodged and emptied easily without you having to fish your hands into the wet slush.

Speed of Functions

The machine weighs 9.5Kgs, light-weight enough to whirl around the pool freely at a fast pace. Each cleaning cycle lasts for 1 hour 30 minutes that can be extended to 3 hours 30 minutes. Consuming 150 Watts of energy for every hour of scrubbing and cleaning, Zodiac V4 4WD robotic pool cleaner is a fast machine that performs optimally in pools sized 15×7 m and below.

Certified to comply with the Australian safety standards, the model is undoubtedly one of the most easy-to-use and performing machines to have rolled out of the brand.
