The best robotic pool cleaners for a sparkling clean pool


Few people enjoy vacuuming their pools, but it’s an important maintenance job that limits algae growth and allows the chemicals in the water to work more efficiently.

Many people are turning to technology – in the form of robotic pool cleaners – to do the job for them. Robotic pool cleaners work similarly to home robotic vacuums, so you can set sensor limits and choose how they work. You can even set some robotic pool cleaning models to work on a preset schedule so they can clean your pool when you are sleeping, running errands, or at work.

The best option for robotic pool cleaners


Before deciding on a robotic pool cleaner, take the time to consider a few parameters that will aid you in your purchase decision.

Pool bottom material

One of the most important points to consider when choosing a robotic pool cleaner is the type of bottom and material of your pool. If that sounds easy, keep in mind that pool floors can be flat, rocky, irregular, or sloping. Once you’ve considered the type of floor, make sure you know if it’s fiberglass, vinyl, or tile. Not all robotic pool cleaners work with all floor materials. In fact, some robotic floor cleaners can damage certain types of floors. So choose a floor that is suitable for the specific material of your pool floor.

Pool shape

The shape of your pool plays a key role in your robotic pool cleaner options. If you have a round or rectangular pool with no irregularities, you can easily find a robotic pool cleaner that will do the job. However, only certain models can process customized shaped pools.

Another basic consideration is whether your pool is in the ground or above the ground. Robotic pool cleaners that can clean the sides of a pool are great for in-ground pools, but they can put too much stress on the wall of above-ground pools.

Pool size

The size of your pool is another important factor. Every robotic pool cleaner comes with an extension cord, and cord length is important. If you have a small 20 foot pool, the required length of extension cord is much shorter than that of a 50 foot pool.

The pool size also determines the speed at which your robotic pool cleaner does its job. A pool cleaner designed for a 30 foot pool can clean that pool in just two hours. If you try to use the same pool cleaner in a 50 foot pool, you will likely find that the extension cord is not long enough. Even if the cord were long enough, the robotic pool cleaner would take twice as long to complete the cleaning and may not have the storage capacity to pick up the debris it collects.

Filtration Skills

Robotic pool cleaners work best when you also consider the type of debris in your pool. That depends on your landscape, the climate and your geographic location. All of these contribute to the type of dirt, sand, pollen, seeds, leaves, twigs, and insects that drift into your pool. For example, if your garden is filled with trees, you need a robotic pool cleaner with a large filter basket that won’t fill up too quickly. If dirt, sand, and pollen are the main types of waste in your yard, consider robotic pool cleaners with ultra-fine filters that trap dirt from the water.

Programming and scheduling

Some robotic pool cleaners require you to start them manually. With others, you can set a daily or weekly schedule for their operation. The cleaner can either remain in the pool or you can remove it and use it again in time for the scheduled cleaning.

Our top picks

The best option for robotic pool cleaners: Dolphin Nautilus CC Plus Automatic Robotic Cleaner


The Dolphin Nautilus CC Plus robotic pool cleaner uses two scrubbing brushes and a large filter system to clean and collect leaves, twigs, dirt, pollen and other debris in just about two hours. You can choose to run the robotic pool cleaner every day, every other day, or every third day. The robotic pool cleaner has wall climbing features for cleaning underground swimming pools up to 50 feet in size. This cleaner is easy to use on all types of pool floors and has a tangle-free swivel cable so it can circulate freely.

The best robotic pool cleaner option: PAXCESS Automatic Pool Cleaner


The Paxcess robotic pool cleaner in the ground / above ground is ideal for almost any type of pool. The extra-large filter baskets can easily handle twigs, leaves and other large debris and jetsam. The cleaner uses four PVA sponge rollers for traction when climbing walls and a twist cord to prevent tangling. The Paxcess can be scheduled to automatically clean for one, two or three hours, depending on the amount of dirt in the pool. The plug-and-play robotic pool cleaner is ideal for swimming pools up to 50 feet in size.

The best option for robotic pool cleaners: Aiper Automatic Robotic Pool Cleaner


You can use the Aiper Robotic In-Ground / Above Ground Pool Cleaner for pools with any type of bottom to remove dirt from small leaves and twigs to fine particles of dirt and sand. The robotic pool cleaner uses 4 PVA brushes to clean both in-ground and above-ground pools up to 50 feet in size. This robotic pool cleaner has anti-rollover technology that keeps it straight when climbing walls. You can also choose to have your pool cleaned automatically for one, two or three hours.

The benefits of a robotic pool cleaner

Regular cleaning of your pool is a must, although it is a time-consuming and stressful task. A robotic cleaner does the job for you in around two to three hours.

Regular cleaning also extends the life of your pool as it removes dirt and debris more efficiently than manual cleaning. A robotic pool cleaner also catches dirt that would otherwise be trapped in your filtration system. A robotic pool cleaner reduces the need for repairs and pool cleaning service, saving you time and money. The following points summarize the benefits of robotic pool cleaners.

  • Robotic pool cleaners remove more dirt and debris from your pool than other cleaning methods.
  • With an easy-to-use robotic pool cleaner, you will also save money on a professional cleaning service.
  • Robotic pool cleaners save you time and energy as most pools are clean within three hours.

Robot pool cleaner FAQs

Consider these frequently asked questions about robotic pool cleaners.

Question: Can you leave a robotic pool cleaner in a pool?

You can leave the robot cleaner in the pool without any immediate negative consequences. However, the longer time underwater wears out the robot cleaner faster than if it had been removed and cleaned after the cleaning cycle was complete.

Q. How often should I use my robotic pool cleaner?

Robotic pool cleaners can be run on a daily basis when the pool is in heavy use. If the pool is not used every day, weekly cleaning should take care of your pool.

Question: How do you maintain a robotic pool cleaner?

Robotic pool cleaners work like robotic vacuums. As with robotic vacuums, you need to empty and clean robotic pool cleaners in order for them to function properly. The brushes under the robot and the side brushes must be cleaned regularly to prevent the robot pool cleaner from malfunctioning.
