Features to look for in the best pool vacuum for algae
Before we dive in, it’s worth understanding that a pool robot will maintain a clean pool but won’t clean up an existing green mess. If you already have an algae problem, it’s most likely a chemistry issue that you need to test and resolve first. Once you’ve fixed it, add the robot once the shock levels have dropped to prevent it from happening again.
So, with that cleared up, when it comes to keeping treacherous algae at bay, you need a robotic cleaner that can handle the task. Before we dive into the recommendations, let’s quickly look at some features you’ll want to keep an eye out for.
When choosing a robotic cleaner, you first need to consider the size and depth of your pool. If your pool is small and cozy, opt for a cleaner with the perfect cleaning power. If you have an above-ground pool, look for a specially designed robot that can conquer its unique challenges. Don’t worry if you have a saltwater pool, there are cleaners tough enough to handle saltwater dirt.
Next, consider the surface of your pool. Is it covered in tiles? If so, what are the tiles made of? Whether it’s a vinyl, fiberglass, concrete, or pebble tec pool, some surfaces are more delicate than others and require specific handling. You also need to determine if your pool needs and can withstand powerful scrubbing.
When cleaning and preventing algae, it is essential to consider the type of filter the pool robot uses because fine debris can pass through basic filters. The best filters for algae are ultra-fine filters, or even better, Dolphin robot pool cleaners use NanoFilters® to capture super fine particles like algae.
Maintenance is another important factor to consider. Think about the average needs of your pool and any special requirements it may have. If you live in a humid area with lots of sunlight, you might be prone to algae growth. Consider the proximity of your pool to plants, trees, and soil, as well as the type and speed of debris accumulation.
Lastly, coverage is crucial. If you want your pool to be clean and free from green sludge, you need a robot with excellent navigation that can systematically reach into corners and cover the entire surface. Pay attention to the area the cleaner covers and make sure it’s smart enough to brush those beautiful curves.
Remember, by considering these factors and choosing the best pool cleaner for algae, you can master the art of pool maintenance and enjoy a sparkling clean pool all year round!
Right. Now on with the robots.

Buyer’s Guide & FAQs
Below are all the tips you should familiarize yourself with as you pick an algae pool cleaner. Read on how algae forms in your pool, the benefits of removing algae from the pool, how to do it, which pool cleaners can do the work excellently, and more.
Types of algae that can be found in a swimming pool
When it comes to the types of algae found in a pool, symbolism can help us dive deeper into the problem.
Green algae, like a persistent weed, takes hold in the forgotten corners, thriving on neglect. It spreads rapidly, fueled by sunlight, demanding swift action. To defeat it, you must unleash the power of super chlorination, purging the pool of its contamination.
Mustard algae, a trickier adversary, creeps slowly but stubbornly. Merely brushing its slimy surface won’t suffice; you must unleash the power of super chlorination to truly conquer it. Regular maintenance, diligent removal of debris, and frequent chemical testing will aid in keeping this alga at bay.
Black algae, a dark menace from the depths, revels in the pool’s abandonment. Its lack of protective slime allows it to infiltrate the hard surfaces, making it a formidable foe. Arm yourself with a stainless-steel brush, attacking it head-on before employing sanitizers.
Lastly, pink algae, a delicate intruder, adorns the waterline and PVC surfaces with its reddish hue. It is accompanied by a white-water mold, an unwelcome companion. Regular brushing and diligent sanitization should keep this bacterial invader at bay. A calcium hypochlorite shock is the prescribed remedy if it has grown unruly.
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 shaded 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. Leaving your swimming pool with many dissolved solids and junk for extended periods gives you 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.
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 pool of algae completely. A recurrence is much easier once a massive algae bloom occurs in your pool.
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 tile/ pool plaster section, 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 increases the amount of chlorine you need in your pool as it consumes it when it should be riding your pool of contaminants. Algae bloom significantly raises 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.
Do Robotic Pool Cleaners Pick Up Algae?
With their powerful suction capabilities and fine filtration systems, some robotic pool cleaners can trap particles as small as 2 microns, including dead algae.
However, it’s crucial to note that while robotic pool cleaners can pick up dead algae and some fine living algae, they are not a complete solution for an algae-infested pool.
If your pool is already overrun with algae, merely running a robotic cleaner will not suffice. Manual scrubbing alongside proper water balancing and treatment, such as shocking the pool with chlorine to kill the algae, are necessary to address the chemistry issue causing algae proliferation.
Once the water chemistry is rectified and algae growth is under control, a robotic pool cleaner can be an excellent tool for maintaining a clean, algae-free pool.
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, the best robotic pool cleaners move around the entire pool while picking up minute filth particles.
Another advantage is they need minimal supervision and effort to clean pools. Robotic pool cleaners pick up dead algae with little effort and ensure active water flow.
Most pool robots 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, reducing algae’s food supply.
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 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.
Do Robotic Pool Cleaners Pick Up Algae?
Robotic pool cleaners now come with upgraded designs such as improved suction power, hyper-grip tracks, and active brushes. Because of this they can efficiently remove young algae growths. Combined with an ultrafine filter, pool owners can immensely lower their pool’s algae population.
Final Thoughts
The Dolphin Nautilus CC Supreme pool cleaner is the top pick as the best pool cleaner for algae.
Given it has three cleaning cycles, the 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 ability to thoroughly clean 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.
