If you own a swimming pool, then you probably know that skimmers are not enough to clear out debris, especially after it has sunk to the bottom. Using a leaf net skimmer can work, but this manual cleaning can be very tiring.

The ideal thing to do is to use an automatic pool cleaner and even though most of them are expensive, they are very handy when it comes to getting rid of the debris as well as scrubbing floors and walls.

With that in mind, this article looks at the best automatic pool cleaners in the market, with a view of helping you get the perfect fit for your pool.

What to Check Before Buying Best Automatic Pool Cleaner?

How to Buy the Best Automatic Pool Cleaner

1. Type of Automatic Pool Cleaner


Suction-side pool cleaners are attached to the suction end of your pool’s circulation system, and they use the generated suction force to move around the pool while scrubbing and collecting debris.


  • Usually very affordable
  • Require less maintenance because of having few moving parts


  • Require running pool pumps to function
  • Puts a lot of stress on the strainer


Pressure side pool cleaners are the opposite of suction side units because they are attached to the return lines of your pool’s circulation system. They usually come with a filtration bag for debris collection because they don’t use the pool’s filter.

However, for the best performance, most of them require a booster pump, which should be bought separately.


  • Relatively affordable
  • Fewer moving parts mean reduced maintenance
  • Does not task the pool strainer with filtration


  • Requires a running pool pump
  • Depending on the model, an additional booster pump may be required


Robotic pool cleaners are easy to use, plug-and-play appliances that are powered using electricity as opposed to water pressure or suction pressure.

This means that they are self-contained units, featuring driving motors, debris filters, and debris bags. As a result, they can function without requiring a running pool pump.


  • Energy efficient
  • Suitable for cleaning floors, walls, stairs etc.
  • Does not strain the pool’s filter


  • Many moving parts require a lot of maintenance
  • Very expensive

Buying Guide: If you have the money, a robotic pool cleaner such as Polaris’ F9450 is the best option to consider.

However, if your funds are limited, pressure and suction cleaners such as Zodiac’s F5 and Hayward’s Poolvergnuegen are still good, although you must always check your filtration system if you decide to use a suction side cleaner.

2. Type of pool

Swimming pools are either in-ground or above-ground. If you have an above-ground pool, then you need to buy a cleaner that is specifically meant for such pools such as Dolphin’s Escape Robotic.

Otherwise, you should get an in-ground cleaner such as Dolphin’s Premier Robotic.

The reason for this is that above-ground cleaners are usually smaller and designed to handle a smaller workload. On the other hand, in-ground cleaners are designed to handle larger and deeper in-ground pools.

3. Filter System

Filter systems ultimately determine the quality of the water that will leave the cleaner.

While suction cleaners do not have their own filtration systems, pressure-side and robotic cleaners usually have cartridge filters, with some high-end robotic models such as Polaris’ F9450 having canister filters.

Canister filters are designed as high-performance strainers, but for cartridges, ensure that it has both fine and ultra-fine screens so that large and small debris (such as algae) can be removed after being scrubbed off the floor and walls.

4. Ease of Use

There are a number of ways to look at this factor. Robotic cleaners are usually very easy to set up because they are plug-and-play. No hose pipes are required.

However, having its own filtration system and bag, you might have to empty the debris very frequently, especially if it is small or if the pool is very dirty.

In the case of a suction-side cleaner, although it may add a lot of pressure to the pool’s filtration system, you won’t have to get it out of the water now and then. Instead, you only have to clean the pool’s main filtration system after some time.

Therefore, an automatic pool cleaner’s ease of use factor depends on how you prefer running your system.
