A Robotic Pool Cleaner is an Effortless Way to Keep Your Pool Sparkling

Mark Schwarz

A robotic pool cleaner is a low-voltage pool vacuum that operates on its own. Do you use a Roomba for your house? A robotic pool cleaner operates pretty much in the same manner, except that it is driven by a power cable rather than by rechargeable batteries. It operates by means of a series of detectors that assist it to scoot through the pool surface without human intervention.

Many pool cleaners, as well as vacuums, operate by being connecting to the pool's re-circulating pump. However, robotic cleaners operate a bit differently. They receive their power from a ground fault circuit interrupter ( = GFCI) outlet (which provides shock protection in the event of a short circuit) for their power supply and sound a bit like a household vacuum since these have brush rollers to efficiently push tiny objects into the vacuum box. The devices are generally self-contained, in that they have a filter and trash receptacle that you regularly empty out.

Most products have their own particular settings, so you may choose to clean the lower part of the pool, the waterline only, or the whole surface. Cleaning the water line is necessary for removing that ring of residue that collects all over the top of the pool. Specialized designs sometimes have chips or detectors telling the vacuum when to go around a corner or climb the pool’s wall. Some can be operated remotely so that you can effectively guide the cleaner from outside the pool. Let’s examine the factors to decide which robotic pool cleaner is best for you.


Types of Robotic Pool Cleaners

You'll see that there are two main types of robotic pool cleaners: one for in-ground pools, and one for above-ground pools.

In-Ground Pool Robotic Cleaners

Two examples of in-ground robotic cleaners are the Dolphin Advantage In-ground Robotic Cleaner (Model No. 99996113-ADV) and the Dolphin Nautilus CC Plus Robotic Pool Cleaner(Model No. 99996403-PC). They use an algorithm to cover every area of the pool exactly once. The Dolphin Advantage can clean pools of up to 33 feet in length, and can clean a pool in under two hours. The Dolphin Nautilus CC Plus can clean pools of up to 50 feet in length. You can program them to clean daily, or once every three days. It can clean up to eight times more efficiently than other non-robotic pool cleaners. They employ dual scrubbing brushes to remove the debris from the floor and walls of the pool, while a top-load cartridge captures debris in the pool’s water. 

Above-Ground Robotic Pool Cleaners

An example of an above-ground robotic pool cleaner is the Kreepy Krauly Prowler 910 Robotic Above-ground Pool Cleaner (Model No. 360321). An above-ground pool cleaner has to employ brushes and wheels that are gentle on the vinyl or PVC of an above-ground pool. The Kreepy Krauly Prowler is one of the more affordable robotic pool cleaners. It employs a top-access mesh filtration basket which is easy to remove and clean. However, some users complain that fine particles make it through the filter. Also, it cleans principally the floor of the pool, but not the walls.

What reviewers say

Why Should You Get a Robotic Pool Cleaner this Summer?

There are a number of advantages to using a robotic pool cleaner:

Water Circulation

Besides the task of cleaning the surface of the pool, a robotic pool cleaner also circulates the pool’s water. This will help mix the chemicals that you add to the pool’s water so that they will be distributed uniformly. It also prevents the growth of algae and other organisms, since they aren’t allowed to settle in one place.

Ultra Comfort

The main advantage of a robotic pool cleaner is its convenience: If you have ever used a manual pool cleaner, you’ll realize how much effort it requires, as well as time. It’s essentially the same as running a vacuum cleaner by hand over the entire pool surface. A robotic pool cleaner will save you both all of that effort, as well as time.

A Cleaner Pool

A robotic pool cleaner employs strong suction and special brushes that scrub the pool surface. A robot will give better results than you could ever achieve by manual cleaning.

Less Daily Cleaning

If you wish, you can employ a robot pool cleaner daily. This will keep residue from accumulating—so each cleaning will be less laborious.

Energy Efficiency

Robotic pool cleaners operate at low-voltage, and will take the load off of your pool’s filter and recirculating pump.

What should You Consider Before Buying a Robotic Pool Cleaner

Before purchasing, consider the following characteristics:

Wall and Stairs Climbers

Not all pool cleaners are programmed to climb the walls of the pool. Some are just able to clean the floor of the pool. On the other hand, some are able to negotiate even the pool’s stairs.

Cleaning Cycles

Most robotic devices have multiple configurations or cleaning cycles for which you can schedule them. You can choose between a "Bottom Only" cycle, or even just "Waterline Only", as well as commanding the robot to clean the entire pool.

Remote Controls

Some pool cleaners, such as the Polaris 9550 Robotic In-ground Pool Cleaner, can be operated by remote control. You can direct the pool cleaner to any particular part of the pool that you’re interested in cleaning.


Make sure that the robotic pool cleaner can handle your size of pool. Some are adequate for 50’ long pools, while others can only handle 33’ or less.

Important Features

What Features Should You Look for in Robotic Cleaners for Pool?

Suction Power

The suction power of a robotic pool cleaner is usually displayed as Gallons per Minute (= GPM). Some, such as the Zodiac MX8 Suction-Side Pool Cleaner, gives good results running at 20 GPM.

Power Cord

Many low-end robotic pool cleaners have a problem with their power cable getting tangled. This has been an enormous issue for years—but pool cleaners with a mechanical swivel have an effective solution. Other solutions include technological developments such as gyro technologies and dual-drive motor mechanisms.


Many robotic pool cleaners have a top-load cartridge filter. This configuration makes it very easy to remove and rinse the filter. Other models employ a bottom-load filter, which requires that you turn the robot upside-down to get at the filter. The finest cleaners claim that they can filter out particles more than 2 microns in size.

Power Washing Jets

Some robotic pool cleaners, such as the Aquabot Turbo T Jet Robotic In-Ground Pool Cleaner. employ power-washing jets. These blast at the debris that adheres to the pool’s walls and floor, making it easier for the brushes to remove the silt and fine particles.

Final Verdict

Whether you have an in-ground or above-ground pool, you should be able to find a robotic pool cleaner that will suit your pool’s size, as well as your pocketbook. You’ll be able to choose from among robotic pool cleaners capable of cleaning the pool floor, the pool’s walls, the water line, and even the stairs of your pool!

About Best-Reviews.guide

Think of the last time you bought something you really cared about. Maybe it was a life insurance policy. Maybe it was a coffee pot. Some people really care about lip balm.

Think of the amount of Googling you did, the types of people and publications you turned to for advice, until you were confident you were buying the best thing for you.

Who we are and what we do

Best-Reviews.guide is the site to turn to when you're about to buy something. From heated blankets to trampolines to cordless drills, we compare the top products in thousands of categories to give you the most reliable purchasing advice. Our goal is to make it easy for you to pick the best product and be confident in your decision.

Why trust Best-Reviews

Best-Reviews spends thousands of hours researching, analyzing, and testing products to recommend the best picks for most consumers. We only make money if you purchase a product through our links, and we never accept free products from manufacturers.

How Do We Work

We’ve assembled a team of researchers and reviewers who each bring specialized skills and expertise. (And this team is, of course, how we’re able to review so many products!). Our testing methodology looks something like this:

  • We send our Research Team out into the marketplace (i.e., the places you shop). They participate in online forums, monitor trends, follow industry news, rub elbows with thought leaders and keep an eye on new advancements in home and technology.

  • Our Editorial Team picks apart the data they gather to identify products and services of note. Their selections are based on a number of factors, including cost, availability, popularity, etc. Sometimes they’ll suggest a few dozen products for review; sometimes more.

  • When the final list is complete, our reviewers reach out to manufacturers in search of no-strings-attached samples or products available on loan. Side note: Most manufactures are happy to provide samples – never mind the possibility of a bad review – because they believe in the quality of their products and look forward to the free press – good, or bad. In some instances, when a product sample is not available, we head to the store and shell out the cash to pick it up just like you would.

  • With products in hand, our reviewers begin the meticulous review process, which includes using most products just as you would. This ensures we’re able to identify and communicate each product’s strengths and weaknesses in a way that makes sense to you.

  • Among other things, our tests gather data on features, ease of use, durability and the level of customer support provided by the manufacturer. Using a proprietary weighted system (i.e., a complicated algorithm), the data is scored and the rankings laid out, and we award the three top-ranked products with our Gold, Silver and Bronze Awards.

  • We then lay out each product grouping in a side-by-side comparison that’s unique to Best-Reviews Guide. Of course you can click on each product for a more in-depth look into what sets it apart from the others.

We also keep our reviews updated

A review may look simple and straightforward, but there’s a good chance it took over a month to complete. Something more complex? Try several. That’s because a good review is never finished. We continue to research, keeping our content updated by reviewing new products or making changes based on things like product recalls and emerging trends.

Our business hinges on credibility, and how useful each review is to you. We promise to tell the story of what we’ve found in a way that’s worth your time, so you can get what you need and get on with your day.
