How To Choose the Right Automatic Pool Cleaner Type

A clean pool … it’s what we all want. Now comes the tricky part: How do we make that happen? Some of us prefer the ease of hiring a pool service, but that can be pricey. Others like to get their hands dirty and handle the cleaning themselves. And some of us don’t necessarily have the budget to afford a pool service or the time/desire to do it ourselves. If you fall in that last group, this post is for you. What you need is an automatic pool cleaner.

Automatic pool cleaners are a great option for anyone looking for an affordable, easy solution to keeping a pool healthy, beautiful, and swim-ready. But there are a few things to consider when deciding between types of pool cleaners. So which type of automatic cleaner is right for you? Let’s jump in and find out.

There are three types of automatic pool cleaners, with options to fit just about any budget:

Suction Side Pool Cleaner

Pressure Side Pool Cleaner

Robotic Pool Cleaner

Before discussing any of the cleaners, it is important to note that between pressure and suction cleaners, most pools are only plumbed to be compatible with one or the other. The first step to determine which cleaner to purchase is figuring out what type is compatible with your system. Robotic cleaners, on the other hand, are not tied into your system. They are therefore compatible with any pool, even if you already have a dedicated suction or pressure line.

Here is a quick overview of each type to help make your decision more clear.

Suction Side Pool Cleaners

Suction side automatic pool cleaners work with the dedicated suction line in your pool, or they can connect to your pool’s skimmer. They use the suction generated by the pool pump to propel the cleaner throughout the pool, vacuuming and cleaning pool surfaces while dirt and debris is removed by the pool filter. These cleaners are often the least expensive of the three types.

Suction side cleaners are great for removing fine dirt and debris, but can burden your pump and filter if there are a lot of larger debris like rocks, nuts, leaves or branches in the pool to clog it up. If your pool has a heavy debris load, attach an in-line leaf canister to the cleaner hose to prevent the pump basket from filling with debris.

Suction Side Cleaner

Pros

  • Lowest cost
  • Fewer moving parts
  • Easy maintenance
  • Good for finer dirt and tough-to-reach areas

Cons

  • Increases the load of dirt and debris on the filter, increasing the pressure and requiring more frequent backwashing or cleaning
  • Pump must be operating for cleaner to work

DIY TIP: Always remove your automatic pool cleaner before adding chemicals, especially pool shock. Some chemicals can damage parts of the cleaner.

Pressure Side Pool Cleaners

As the name suggests, pressure side automatic pool cleaners use pressure side water flow from the pool's return line. This pressurized water propels the cleaner throughout the pool, and pushes debris into an attached filter bag. Essentially, the water returned back into your pool is what fuels the cleaner.

Unlike suction cleaners, pressure cleaners don’t use your pool’s filtration system to filter out dirt and debris. Instead, they use a filtration bag to collect the debris. This relieves pressure and wear on your filtration system and helps prolong the life of your pool equipment. It's one of the more practical options for filtering out leaves and other large debris, as compared to suction or robotic cleaners. And if your pool is heated, pressure cleaners help circulate the pool and distribute the heat.

Pressure Side Cleaner

Pros

  • Lower cost
  • Easy maintenance
  • Lowers dirt and debris load on filter
  • Good for pools with lots of leaves

Cons

  • Pump must be operating for cleaner to work
  • Most models require an extra booster pump
  • Increased operating costs if both pumps are required (they would need to run at the same time)
  • Must empty filtration bag when full

SAFETY TIP: For safety purposes, always remove your automatic pool cleaner from the pool before swimming. Long cords and hoses can be hazardous as the cleaner moves around the pool.

Robotic Pool Cleaners

Robotic cleaners are compatible with all pool types, and are highest quality automatic pool cleaner option money can buy. These cleaners run off a low voltage motor that is powered by plugging into a standard GFCI outlet. Unlike suction and pressure side cleaners, robotic pool cleaners are not connected to your pool equipment in any way. Any debris that is picked up is stored in a filter canister inside the cleaner, which need to be cleaned out periodically to ensure optimal performance.

Because it has its own onboard filter, robotic cleaners prevent your pool filter from having to deal with much of the debris in the pool. Just like a pressure cleaner, this feature prolongs the life of your pool equipment, and increases the amount of time between filter cleanings. Robotic pool cleaner filters offer remarkably high filtration efficiency, with some models even rivaling the power of a DE filter to filter out the smallest microns of particles. If you want the highest level of clean, maximum energy efficiency, and reduced wear and tear on your pump and filter, a robotic pool cleaner might just be the one for you.

Robotic Pool Cleaners

Pros

  • Supports simple “plug and play” operation
  • Superior cleaning efficiency in the built-in-filtration system
  • Independent of pool pump and filter, reducing wear and tear on pool equipment
  • Energy efficient
  • Can clean and scrub the pool floor, steps, and waterline
  • Moves high volume of gallons of water each hour, acting as secondary filtration system
  • Programmable features (timer, path, etc.)
  • Newer models are Bluetooth compatible

Cons

  • Highest upfront cost
  • Requires emptying the built-in filter
