Owning a swimming pool is one of the best ways to enjoy summer, but keeping it clean can quickly turn into a time-consuming chore. Dirt, leaves, algae, and other debris don't take long to turn sparkling water into a maintenance headache. That’s why more and more pool owners are turning to automatic pool cleaners — smart devices that take the hassle out of regular cleaning.
But not all pool cleaners are built the same. From affordable suction-side models to high-tech robotic units, each type has its own strengths and ideal use cases. Choosing the wrong one can mean wasted time, higher energy costs, or disappointing performance.
In this guide, we’ll break down the three main types of automatic pool cleaners, compare how they work, and help you decide which one is right for your pool — whether you're a new pool owner or upgrading your cleaning setup.
Types of Automatic Pool Cleaners
Automatic pool cleaners fall into three primary categories: suction-side, pressure-side, and robotic. Each type uses a different cleaning mechanism and serves a different purpose depending on your pool’s size, location, budget, and how much debris it typically collects. Below, we’ll walk you through each type, explain how they work, and highlight the pros and cons to help you make an informed decision.
1. Suction-Side Pool Cleaners
Suction-side automatic pool cleaners are the most common and budget-friendly option on the market. They connect directly to your pool’s existing filtration system — usually through the skimmer or a dedicated suction line. As your pool’s pump runs, the cleaner moves around the pool floor (and sometimes walls), sucking up dirt and debris, which are then passed through the filter.
Advantages:
- Affordable upfront cost – ideal for budget-conscious owners.
- Simple installation – often plug-and-play with minimal setup.
- Low maintenance – few moving parts mean fewer breakdowns.
Drawbacks:
- Relies heavily on your pool’s filtration system, which can wear out faster.
- Less powerful than other types, making it less effective at cleaning large debris like leaves or twigs.
- Reduced mobility – struggles with stairs, walls, or irregular pool shapes.
Best for: Small to medium-sized pools with minimal debris and standard shapes. Ideal for homeowners looking for a low-cost cleaning solution without extra pumps or power sources.
2. Pressure-Side Pool Cleaners
Pressure-side cleaners use the force of water returning to the pool to move and clean. They connect to the return jet and often come with a separate filter bag that collects debris, meaning they don’t rely on your main filtration system. Some models may require a booster pump for added power.
Advantages:
- Excellent for handling larger debris such as leaves, bugs, or acorns.
- Keeps your pool filter cleaner by storing debris in a separate bag.
- Durable and effective for medium to large pools.
Drawbacks:
- May require a booster pump, increasing initial and operational cost.
- More complex installation compared to suction-side units.
- Less energy-efficient than robotic models due to pump dependency.
Best for: Medium to large pools, especially in areas surrounded by trees or landscaping. Great for users who want thorough cleaning without overworking their filtration system.
3. Robotic Pool Cleaners
Robotic pool cleaners are the most advanced — and often the most expensive — option. These cleaners operate independently of your pool’s filtration system and run on electricity. Equipped with onboard motors, brushes, and smart navigation systems, robotic cleaners can scrub the floor, walls, waterline, and even stairs with exceptional precision.
Advantages:
- Superior cleaning performance – removes fine dirt, algae, and even microscopic particles.
- Energy-efficient – uses less electricity than running the pool pump for long periods.
- Self-contained system – no strain on your pool’s filter or pump.
- Smart features – many models include programmable schedules, smartphone controls, and intelligent navigation.
One popular option in this category is the Spino E1 Robotic Pool Cleaner, which offers intelligent navigation, strong cleaning power, and easy app control — all with zero connection to your pool’s filtration system.
Drawbacks:
- Higher upfront cost – robotic units can be 2–3 times more expensive than suction-side cleaners.
- Requires occasional maintenance – filter cartridges need to be emptied and cleaned.
- Needs a power outlet – may require planning for outdoor electrical access. Get more cons about robotic pool cleaners here.
Best for: Pool owners who want a “set-it-and-forget-it” solution and are willing to invest in long-term efficiency and performance. Robotic cleaners are ideal for pools of any size or shape, especially those with irregular surfaces or frequent debris buildup.
Summary
Each type of automatic pool cleaner offers unique benefits depending on your needs:
- Suction-side cleaners are great if you’re on a tight budget and have a simple, relatively clean pool.
- Pressure-side models strike a balance between power and cost, especially useful for large debris.
- Robotic cleaners are the best choice for those who want the most effective, energy-efficient, and low-maintenance solution — and don’t mind paying more upfront.
Next, we’ll provide a side-by-side comparison table so you can quickly assess which type aligns with your priorities.

If you're after affordability and simplicity, suction-side cleaners get the job done. For larger pools or yards with trees, pressure-side units offer stronger cleaning without overloading your filtration system. Robotic cleaners, though more expensive, deliver unmatched performance, energy efficiency, and convenience — especially for busy pool owners who want hands-off maintenance.
