Maintaining a clean and sparkling swimming pool requires regular attention to both water chemistry and physical debris removal. While chemical treatments keep the water sanitized, pool cleaners are responsible for scrubbing the walls, floors, and waterline to remove dirt, algae, and other contaminants. The market offers a wide variety of pool cleaners, each tailored to specific pool types, budgets, and maintenance needs. In this comprehensive guide, we’ll explore the most common types of pool cleaners, their advantages and limitations, and what to consider when selecting the best option for your pool.

1. Why Do You Need a Pool Cleaner?

Before diving into the different types of pool cleaners, it’s important to understand their essential role in pool maintenance. Without a cleaner, dirt, leaves, and other debris can settle on the pool floor, leading to discoloration, algae growth, and poor water circulation. Manual cleaning is time-consuming and labor-intensive, while the wrong type of automatic cleaner can underperform or damage your pool surface.

Pool cleaners not only save time but also contribute to the longevity of your pool by preventing sediment buildup that can wear down surfaces and clog filtration systems. The right cleaner depends on the size of your pool, the surface material (vinyl, concrete, fiberglass), your budget, and how much automation you desire.

2. Overview of the Main Types of Pool Cleaners

There are five primary categories of pool cleaners:

1. Suction Side Pool Cleaners
2. Pressure Side Pool Cleaners
3. Robotic Pool Cleaners
4. Electric Robotic Cleaners
5. Manual Pool Cleaners

Each type has distinct mechanisms, benefits, and drawbacks. Understanding their features can help you choose the most suitable one for your needs.

Suction Side Pool Cleaners: Classic and Cost-Effective

Suction side pool cleaners operate by connecting to the pool’s existing filtration system—specifically the skimmer or dedicated suction port. They rely on the power of the pool pump to create suction, which moves the cleaner across the pool surface while it vacuuming debris into the filter or a collection bag.

How Suction Side Cleaners Work

These cleaners attach to a hose that connects to the skimmer or a dedicated suction port often referred to as the “vacuum line.” As water is pulled through the system, it creates a Venturi effect that moves the cleaner around the pool. The debris is vacuumed up alongside the water and either caught in a filter or debris canister.

Pros of Suction Side Cleaners

• Cost-effective — Generally the cheapest automatic pool cleaner option.
• Easy to install — No additional equipment required beyond the existing pool pump and filter.
• Simple maintenance — Few moving parts mean fewer issues and lower long-term costs.

Cons of Suction Side Cleaners

• Reduced filtration efficiency — May strain the pool filter as debris passes through it.
• Limited movement — Less aggressive cleaning patterns can leave some areas untouched.
• Not suitable for large debris — Works best with small particles and fine dust.

Pressure Side Pool Cleaners: Power and Performance

Pressure side cleaners operate differently from suction side models. Instead of pulling water and debris through the filter, they are connected to the pool’s return line—usually via a dedicated booster pump—that pushes out water to power jets on the cleaner. These jets propel the cleaner and help dislodge dirt and debris from the pool surface.

How Pressure Side Cleaners Work

These cleaners use water pressure from a booster pump to move around the pool and collect debris into a separate filter bag. The waste is then either collected in this bag or released into the pool’s main filter system depending on the model.

Pros of Pressure Side Cleaners

• Effective for large debris — Can handle leaves, twigs, and heavier particles more efficiently than suction cleaners.
• Advanced scrubbing features — Many models have onboard pre-filters or fine filtration systems for better cleaning results.
• Strong propulsion — They move quickly and can clean large pool surfaces efficiently.

Cons of Pressure Side Cleaners

• Require a booster pump — Adding a booster pump increases the cost significantly.
• Higher energy consumption — Booster pumps can be power-hungry and increase utility costs.
• Less popular with saltwater pools — The higher salinity can affect the internal parts of pressure side cleaners over time.

Robotic Pool Cleaners: Smart and Efficient

Robotic pool cleaners are standalone, fully automatic units powered entirely by electricity. They have their own filtration system, motor, and intelligent programming that allows them to navigate the pool efficiently and effectively.

How Robotic Cleaners Work

These cleaners operate independently of the pool’s filtration system. Plugged into a power source, the unit moves automatically using brushes, scrubbing heads, and onboard filtration bags or cartridges that trap debris from fine dust up to large particles. Some models even connect to Wi-Fi or apps for precise scheduling and troubleshooting.

Pros of Robotic Pool Cleaners

• Onboard filtration system — Filters water independently, reducing strain on the main system.
• Energy efficient — Run on low-power motors separate from your pool pump, saving energy.
• High-tech features — Includes programmable timers, smart navigation apps, and self-docking capabilities.

Cons of Robotic Pool Cleaners

• Higher initial cost — Often the most expensive type of automatic cleaner.
• May require maintenance — Filters and brushes must be cleaned and replaced over time.
• Variability in performance — Low-end models may not perform as well as top-tier ones in deep or irregularly shaped pools.

Electric Robotic Cleaners

Electric robotic pool cleaners fall under the broader robotic pool cleaner category but merit separate mention due to recent advancements. These cleaners have evolved to incorporate features such as energy efficiency, ultra-fine filtration, and advanced navigation systems. Some models can be connected to smartphone apps, allowing pool owners to track cleaning sessions or adjust routes remotely.

Who Are Electric Robotic Cleaners Best For?

They’re best for pool owners who value efficiency and ease of use. These cleaners are suitable for a variety of pool surfaces, including fiberglass, concrete, and vinyl-liners. If you’re aiming for minimal maintenance and optimal cleanliness, an electric robotic pool cleaner can provide the most hands-off strategy among all automatic cleaners.

Manual Pool Cleaners: Old School but Reliable

Manual pool cleaners require the pool owner to push or drag the cleaner across the floor and walls of the pool manually—typically via a long pole attached to a vacuum head. They’re often used in combination with a sand or DE filter or can be attached to a portable vacuum system or pool pump.

How Manual Cleaners Work

A basic vacuum head is attached to telescoping poles and a hose that connects to the skimmer or filter pump. As water is pulled through the system, debris is drawn into the pump and eventually into the filter. The process is entirely hands-on and repetitive but effective for spot cleaning or periodic maintenance.

Pros of Manual Cleaners

• No electricity required — Operates using the pool’s existing pump and filter system.
• Inexpensive startup cost — One of the most affordable cleaning methods available.
• Highly versatile — Can be used on any pool type or size with proper attachments.

Cons of Manual Cleaners

• Physically demanding — Requires effort and time to clean large pools thoroughly.
• Less consistent coverage — Human error may lead to missed spots or uneven cleaning.
• No automation — Ideal only for pools that require less frequent cleaning.

What Are the Main Categories of Pool Cleaners Available?

Pool cleaners are primarily divided into three categories: manual, semi-automatic, and automatic (robotic) pool cleaners. Manual cleaners require the pool owner to physically operate the device, guiding it through the pool to suction up debris. These are typically the most affordable but demand more time and effort.

Semi-automatic cleaners, on the other hand, connect to the pool’s filtration system or a booster pump and move around the pool with some level of automation, though they may still need some guidance. Robotic pool cleaners are fully automatic, using advanced navigation systems to clean the entire pool without any supervision. They are the most expensive but also the most efficient and convenient option for most pool owners.

How Do Suction-Side Pool Cleaners Work?

Suction-side pool cleaners operate by harnessing the power of the pool’s existing filtration system. As the pool pump runs, the cleaner is pulled through the water, collecting debris which is then filtered through the pool’s skimmer or pump basket. These cleaners are generally easy to install and do not require a separate pump or electricity, making them a budget-friendly option.

However, suction cleaners may struggle with larger debris and tend to reduce the efficiency of the pool’s filtration system since debris bypasses the main filter. Additionally, their movement can be somewhat random, which means they may miss spots or require manual intervention to ensure full pool coverage. Despite these drawbacks, they remain a popular choice for smaller pools or for those looking for a low-maintenance cleaning strategy.

What Are the Benefits of Pressure-Side Pool Cleaners?

Pressure-side pool cleaners use the pool pump’s water return line to operate, propelling water through jets to move the cleaner around the pool. These cleaners come equipped with their own debris canister, so they do not rely on the pool’s filtration system, preserving its efficiency. They are especially effective at collecting large debris and can clean the pool faster than suction-side models.

One of the key advantages of pressure-side cleaners is their powerful scrubbing action, which helps dislodge dirt and algae from the pool surface. However, they may require a booster pump for optimal performance, which can add to installation costs. While they are highly efficient and require little user input once set up, they typically come at a higher price than suction-side models and require regular maintenance on their internal components.

Why Are Robotic Pool Cleaners Considered the Top Choice for Many Pool Owners?

Robotic pool cleaners are widely regarded as the most advanced and efficient cleaning solution available today. They operate independently of the pool’s filtration system, using their own built-in pumps and filters to trap debris. With intelligent navigation systems, robotic cleaners scan the pool and optimize their cleaning paths, ensuring thorough cleaning with minimal energy consumption.

In addition to their efficiency, robotic cleaners are known for their user-friendly operation. Most models can be programmed to clean on a schedule and feature self-parking modes for easy retrieval. They also consume less energy compared to other cleaners and contribute to reducing water and electricity usage over time. Although their initial cost is higher, their long-term maintenance savings and performance make them a preferred investment for many pool owners.

How Do I Choose Between In-Ground and Above-Ground Pool Cleaners?

The type of pool you own—whether in-ground or above-ground—plays a significant role in selecting the appropriate cleaner. In-ground pools typically require heavier-duty cleaners due to their size, depth, and varied surfaces. Robotic or pressure-side cleaners are often the best fit for in-ground pools because of their durability and efficiency.

Above-ground pools, on the other hand, are usually smaller and have vinyl or metal walls, which require gentler cleaning mechanisms. Some robotic cleaners have specific models designed for above-ground pools, including lighter materials and adjustable cleaning heads to avoid punctures. It’s essential to verify compatibility with your pool type before purchasing any cleaner to ensure optimal performance and avoid causing damage to the pool structure.
