Our Evaluation Method

Over the course of several months, we tested 23 different robotic pool cleaners in real-world pool conditions. Prior to each test, we prepped the pools by performing tasks like backwashing, cleaning filters and pump baskets, and adjusting chemical balances as needed.

Once the pool was ready, we set up each robotic cleaner, starting by timing the setup process from unboxing to full assembly. For battery-powered models, we recorded how long they took to charge. For Wi-Fi-enabled cleaners, we downloaded the relevant app and registered the device.

Each pool cleaner was used at least once a week over a period of 2-4 months, depending on pool usage. Before every cleaning, we noted the type and amount of debris in the pool. During the first cleaning session, we observed the entire process, taking note of the areas the robot could and couldn’t reach. For subsequent cleanings, we both supervised and occasionally left the cleaner unsupervised for certain stretches.

After each cleaning, we recorded the time taken, how well the pool was cleaned, and what types of debris were collected. We also performed maintenance tasks like emptying the collection bag and cleaning the filter. Throughout our testing, we considered factors such as ease of use, design, weight, noise level, cleaning efficiency, and maintenance ease. Additionally, we evaluated cord length (when applicable), its tendency to tangle, and whether the robot ever got stuck. Lastly, we assessed whether the price of each cleaner was justified by its performance.

Expert Guide to Shopping for Robotic Pool Cleaners

Pool Type

While most robotic pool cleaners are effective for both in-ground and above-ground pools, certain models are tailored for just one of these pool types. Compact models are particularly suited for above-ground pools due to their smaller size, but it's important to verify that the cleaner you're considering is compatible with your specific pool. Moreover, the robotic cleaner you choose should be compatible with various pool surfaces such as concrete, ceramic tiles, vinyl, or fiberglass, according to Guo.

Cleaning Coverage

Most robotic pool cleaners are capable of managing pools up to approximately 50 feet in length. However, the exact coverage depends on factors like battery capacity, cleaning performance, power consumption, and the level of intelligence in the robot. As Guo points out, less advanced models may require multiple cleaning cycles and sometimes miss spots.

Cord Length

Although some robotic pool cleaners are cordless and run on batteries, the majority come with long cords that must be connected to a power source. These cords typically range from 30 to 75 feet, with the average being about 60 feet. Zimmerman states that this length is sufficient to cover most pools, even the longer ones.

If necessary, you can extend the cord by using an extension, especially if your pool's size or shape makes it difficult to reach all areas. Guo notes that determining the perfect cord length can be tricky due to the variety of pool sizes and shapes, so an extension cord could be quite useful. Additionally, when opting for a corded model, it's important to think about the weight of the cord in addition to its length. Guo warns about the challenge of handling a bulky cord that's over 60 feet long.

Features

Robotic pool cleaners offer a wide array of features that are worth evaluating. Here are some key ones to look out for:

• Advanced navigation technologies like sensors or mapping, which can help the cleaner move around the pool more effectively and ensure thorough coverage, according to Phil Whitman from Proactive Pool Solutions.
• Programmable cleaning cycles and modes that you can adjust according to your pool’s size and specific needs. Whitman notes that, "The ability to program and customize cycles ensures an efficient and comprehensive clean." This is generally available in Wi-Fi-enabled models that can be controlled through an app.
• Strong suction and scrubbing power that enable the robot to "effectively eliminate dirt, debris, and algae from both the pool floor and walls," according to Whitman.
• Energy-saving motors that help "cut down on electricity usage and minimize environmental impact," says Whitman.
• Remote controls or mobile apps that let you manage the cleaner from a distance. Many models we recommend, like the Dolphin Explorer E50, our Best Smart pick, offer app connectivity for ease of control.

Additional Robotic Pool Cleaners to Explore

Common Questions You May Have

Is investing in a robotic pool cleaner worthwhile?

According to Whitman, a robotic pool cleaner is definitely worth the investment. He says, "One of the biggest benefits is the time and effort it saves compared to cleaning your pool manually." Instead of spending hours scrubbing and vacuuming, you can just drop the cleaner in the pool and let it handle the work for you.

Robotic pool cleaners are not only energy-efficient, making them a cost-effective choice in the long run, but they also offer convenience. Many models can be remotely controlled, allowing you to schedule cleaning times. Their effectiveness is another highlight: "Robotic pool cleaners are designed to thoroughly clean the bottom and walls of your pool, as well as remove debris and contaminants that might be missed by other types of cleaners," explains Whitman. Ultimately, he says, "If you value your time and want a clean pool with minimal effort, investing in a robotic pool cleaner is a great decision."

Can robotic pool cleaners tackle larger debris?

It depends on the specific model, says Whitman. "Most robotic pool cleaners are designed to handle smaller debris like dirt, leaves, and insects. However, some models feature larger intake ports or debris bags that can handle bigger debris such as twigs, pebbles, and small rocks."

For pools with substantial large debris, Whitman recommends choosing a robotic pool cleaner with a large debris bag or basket, along with strong suction or scrubbing capabilities. Additionally, you may want to consider a model with a clog-resistant design or a manual cleaning mode, which can assist in removing larger debris that could potentially clog the intake or brushes.

For pools with excessive debris, we suggest the Dolphin Premier, which comes with a large debris bag, powerful suction, and dual scrubbing brushes to ensure thorough cleaning.

What is the typical cost of a robotic pool cleaner?

According to Whitman, "The price of a robotic pool cleaner can vary greatly depending on factors like the model, brand, and features." However, "you can generally expect to pay anywhere from $300 to $1,500 or even more for one of these cleaners."

He further explains that lower-cost models "often come with fewer features and may not be suitable for larger or more intricate pools. Additionally, they might have shorter warranty periods or be less durable compared to higher-end options."

On the other hand, more expensive models tend to offer a range of advanced features and are "better suited for larger or more complex pool designs. They also usually come with longer warranty periods," adds Whitman.

Is it okay to leave a robotic pool cleaner in the pool permanently?

While it's technically possible to leave a robotic pool cleaner in the pool, it's not recommended. According to Guo, "Robotic pool cleaners are built for underwater use, so leaving them in the water for extended periods generally won't cause any immediate functional issues." However, "We advise regular cleaning of the robot, as the debris in the filter can decompose and produce an unpleasant smell."

Zimmerman warns against leaving pool cleaners in the pool for prolonged periods during colder months. He explains, "The cold water causes parts that should be flexible and mobile to become stiff and rigid, which can cause the cleaner to malfunction."
