Buyer’s Guide & FAQs

Below are all the tips you should familiarize yourself with as you pick a robotic pool cleaner. Read on how algae forms in your pool, the benefits of removing algae from the pool,  how to do it, which pool cleaner can do the work excellently, and more.

Why Does Your Swimming Pool Have Algae?

Swimmers with contaminated swimsuits, dirty pool equipment, wind, rain, among other agents, lead to the transfer of algae spores into the swimming pool.

When ideal conditions present themselves, an algae bloom can happen within a short while. Optimal conditions for an algae problem in the swimming pool include warm temperature, chemical imbalance in the water, presence of phosphates, nitrates, carbon dioxide, and sunlight.

However, the primary reason for algae formation in your swimming pool is insufficient cleaning, inefficient filtration, and inadequate water circulation.

Algae are living aquatic microorganisms that multiply rapidly on warm, sunlit days. Using chlorophyll, algae conduct photosynthesis to generate food.

While it can thrive in both sunny and shade conditions, most pool algae strains require some light for survival. They also rely on food, with this being in plenty in a swimming pool environment.

Nearly all contaminants, including pollen and dust particles brought in by the wind, are a food source for algae. By leaving your swimming pool with many dissolved solids and junk for extended periods, you are giving an ideal condition for explosive algae invasion.

Algae is ever-present in swimming pools as even the remains of dead algae bloom offer sustenance to this organism. As soon as there are low chlorine levels, the pool’s pH increases, or the efficiency of your filtration system lowers, the number of algae in your swimming pool can grow exponentially.

Here is an outdoor swimming pool with green algae

What are the Dangers of Algae Build-Up?

Would you want to go for a swim in an algae-laden pool? You will realize that few people desire to swim in a swimming pool full of algae.

Algae on its own are typically not harmful to swimmers. However, swimming pools with algae tend to harbor bacteria like E-coli that may cause violent diarrhea, vomiting, stomach pain, and more.

Thirdly, algae are quite slippery, and their presence on your swimming pool stairs can result in a fall. And you can imagine what knocking yourself out on the pool stairs means if no one is around.

You also need a lot of time and money to rid your swimming pool of algae completely. Once a massive algae bloom occurs in your pool, a recurrence is much easier.

Algae tend to color and cloud pool water, which can reduce visibly at the pool’s bottom and make rescue attempts more difficult.

Besides clogging sanitation pathways in the pool water, algae also block your pool’s filtration system. This decreases the filter’s effectiveness and requires more backwashing or replacement.

Algae may grow in difficult-to-spot areas like inside a filter’s crevices, a rough section of the tile/ pool plaster, behind your pool light, or under ladder treads. Some types of algae send roots into plaster and progressively degrade and taint pool surfaces. Algae may even thrive underneath vinyl pool liners.

Algae increase the amount of chlorine you need in your pool as it consumes it when it should be riding your pool of contaminants. Algae bloom results in a significant rise in your pool’s pH since there is excessive carbon dioxide release.

It is hence necessary to use algae preventative chemicals, pool cleaners, among other ways, to constantly put the algae population in your swimming pool under control.

Unfortunately algae-laden poles are usually harmful to swimmers

Why a Robotic Pool Cleaner is Perfect for Keeping Algae in Your Swimming Pool Under Control

While manually vacuuming your pool ensures you get the most visible sections with algae bloom, you may not always scrub off all the surfaces.

However, robotic pool cleaners move around the entire pool while picking up minute filth particles.

Another advantage of using robotic pool cleaners is they need minimal supervision and effort to clean pools. Robotic pool cleaners scrub off algae with little effort and ensure active water flow.

Robotic pool cleaners now come with upgraded designs such as improved suction power, hyper-grip tracks, and active brushes. Because of this, they can attack young algae growths with more force and offer a better cleaning solution.

Combined with an ultrafine filter, the above features can help pool owners immensely lower the pool’s algae population.

Let your robotic pool cleaner move around your pool at least once a day. This way, you can ensure you minimize dirt particles in the pool water, which reduces the food supply for algae.

Best robotic pool cleaner can help you swimming pool under control

Key Points for Consideration Before Buying?

After choosing a suitable price range, follow this guide to scrutinize the robotic pool cleaners for algae that you pick:

Scope of Coverage of the Robotic Pool Cleaner

Whether you are dealing with algae or any other type of filth, you want to ensure that your pool vacuum cleaner can do the work excellently.

The first thing to look at is your pool size. While some robotic pool cleaners can only handle up to 30 feet pools like the Dolphin E10, others can clean up to a 50-foot pool or more.

Another factor within the coverage is the ability of the robotic pool vacuum cleaner to climb walls. It is best to decide on a product that can handle floors and walls with precision. Some robots can even clean the waterline and ensure the entire pool’s surface gets cleaned.

Ease of Use of the Pool Robot Cleaner

Several factors determine the ease of use of your pool vacuum cleaner. One of them is the straightforwardness of setting up your cleaning schedule, halting the robot’s functioning, among other controls.

The main issue a pool owner may face is the simplicity of setting of the cleaning process. Is it a must for you to be around to get your pool vacuum cleaner operational?

If you don’t mind turning your robotic pool cleaner every time, then the above case is alright. But if you want a pool vacuum that takes automation to a whole different level, go for a product that offers intuitive control features.

You don’t want to find yourself stuck with a pool vacuum compatible with a challenging control app with a steep learning curve.

Another factor to look into is the ease of moving your pool cleaner around. What is its weight? Does it come with an ergonomic carrying handle?

A top filter basket may be suitable if you don’t want to flip over the pool vacuum cleaner to remove dirt. You also want to consider the capacity of the dirt basket. The larger the debris container, the fewer times you’ll have to get out your pool cleaner to empty the contents.

Best robotic pool cleaner robot cleanings dirty swimming pool

Tangling Issues

Tangling prevents your robotic pool cleaner from finishing its job properly. Go for a robotic pool cleaner with a 360-degrees swivel cord to prevent it from tangling. However, some robots get advertised to have anti-tangle cables yet fail to live to the expectation.

Another alternative is to opt for a battery-powered robotic pool cleaner. Here, you want to ensure that the cleaner has a sufficient battery life to handle your pool. You don’t want to get a pool cleaner that cleans halfway and needs charging for six hours before taking some more hours to finish the job.

Reusability/Longevity

When searching for a robotic pool cleaner, you won’t fail to miss displeased customers with units that only lasted a few uses. And considering how expensive some robots are, it is imperative to get a quality product.

Moreover, you can take some measures to ensure that your cleaner serves you for an extended time. For instance, it is unwise to leave your robotic pool cleaner in the water throughout as chemical imbalance tends to hasten wear and tear. Remember to clean its parts and store them properly to ensure longevity.

FAQs

How Do You Vacuum Algae from an Inground Pool?

Let your robotic pool cleaner run over the pool’s entire surface. Ensure you have ultra-fine filters and a suitable swimming pool cleaner able to pick up algae. Also, conduct the cleanliness exercise frequently to avoid excessive algae build-up.

Are Robotic Pool Cleaners Worth It?

Robotic pool cleaners are a worthwhile investment if you take keen consideration as you settle on a product. They save more energy than using a pressure-side or suction pool cleaner, and some can clean vertical surfaces, including the waterline.

When Should I Remove My Robotic Cleaner from the Pool?

You should remove your robotic pool cleaner before adding chemicals into the pool as they tend to lower its lifespan.

Should I Remove My Pool Cover While Using a Corded Robotic Pool Cleaner?

If your cover floats on the surface, you have to get rid of it, but you can leave it if the cover stays a few inches clear of the water. Moreover, you can’t see a full cartridge indicator or battery low alert and may end up wasting valuable time if you cover your pool while cleaning continues.

How Often Should I Use My Robotic Pool Cleaner?

At least once a day for effective algae control.

Final Thoughts

The Dolphin Nautilus CC Supreme pool cleaner is the top pick among the best robotic pool cleaners for algae.

Given it has three cleaning cycles, the dolphin Nautilus CC pool vacuum cleaner allows pool owners to pick what works for them depending on the situation.

Moreover, it has three cleaning brushes, which is not popular as most robots only come with up to two brushes. The brushes work with the pool cleaner’s intense suction power to deliver a thorough cleaning of the pool.

Still, any of these pool cleaners offer a deep clean to wipe off algae from pools. And with our buying guide to help, you should be able to choose a solution that best suits your pool maintenance requirements.
