Cordless Pool Cleaners: The Power of Suction

Cordless robotic pool cleaners offer unparalleled convenience, but a common question arises: do they have enough suction power? This article explores the importance of suction in the cordless pool cleaner, explaining what it is, how it’s measured, and why it’s crucial for effective cleaning. We’ll also address common misconceptions and provide tips for maximizing suction performance.

What is Suction Capacity?

Suction capacity refers to the volume of water a pool cleaner can move or filter within a given time. It’s often expressed in gallons per hour (GPH) or liters per hour (LPH). This metric indicates the cleaner’s ability to draw water and debris into its filtration system. A higher GPH/LPH value generally signifies stronger suction.

However, it’s important to understand that GPH/LPH alone doesn’t tell the whole story. Other factors contribute to cleaning effectiveness, including:

• Pump Design: The efficiency and power of the cleaner’s pump significantly impact suction strength.
• Filter Design and Capacity: The filter’s ability to capture and retain debris without restricting water flow is crucial.
• Nozzle/Intake Design: The shape and size of the intake opening influence how effectively debris is drawn in.
• Cleaning Path and Brushing Action: The cleaner’s movement pattern and the effectiveness of its brushes help dislodge debris, making it easier to be suctioned up.

Therefore, while GPH/LPH provides a useful benchmark, it’s essential to consider these other factors when evaluating a cordless cleaner’s overall cleaning performance.

Why Strong Suction is Crucial

Strong suction is vital for several reasons:

• Effective Debris Removal: Strong suction is necessary to pick up various types of debris, including:
• Leaves and Twigs: Larger debris requires significant suction to be drawn into the cleaner.
• Dirt and Sand: Fine particles require consistent suction to prevent them from settling back onto the pool surface.
• Algae: Suction helps remove both loose and attached algae, preventing buildup and improving water clarity.
• Wall and Waterline Cleaning: As discussed in the previous article, suction plays a critical role in enabling cleaners to adhere to vertical surfaces like walls and the waterline. Without sufficient suction, the cleaner will struggle to climb and clean these areas.
• Efficient Filtration: Strong suction ensures that water is drawn through the filter efficiently, maximizing debris removal and preventing filter clogging.

Suction and Different Pool Surfaces

The pool’s surface material can also influence the effectiveness of suction:

• Vinyl Liners: Vinyl liners are generally smooth, making it easier for cleaners to achieve good suction. However, it’s essential to use a cleaner with soft brushes or tracks to avoid damaging the liner.
• Gunite/Concrete: These surfaces can be rougher, requiring stronger suction to lift debris from the textured surface. Cleaners with powerful brushes and robust suction are better suited for these pools.
• Tile: Tile surfaces can be slippery, especially when wet. Cleaners with specialized brushes or tracks designed for tile are necessary to maintain adequate traction and suction.

Debunking Myths About Cordless Cleaner Suction

A common misconception is that cordless pool cleaners are inherently weaker than corded models. While early cordless models may have had some limitations, advancements in battery technology and motor design have significantly improved their performance. Modern cordless cleaners can offer comparable or even superior suction power to corded models.

Key factors that contribute to strong suction in cordless cleaners include:

• Powerful Lithium-Ion Batteries: These batteries provide consistent power to the motor, ensuring strong and sustained suction.
• Efficient Motor Design: Brushless motors and optimized pump designs maximize energy efficiency and deliver high suction power.
• Smart Algorithms: Advanced software algorithms optimize cleaning patterns and suction performance based on the pool’s shape and debris levels.

Therefore, it’s inaccurate to assume that all cordless cleaners have weak suction. Look for the best pool cleaner models with reputable brands, positive user reviews, and clear specifications regarding suction capacity and performance.

Simple Tips for Maximizing Suction Performance

• Regular Filter Cleaning: As with corded cleaners, regular filter cleaning is crucial for maintaining optimal suction. A clogged filter restricts water flow and reduces suction power.
• Battery Maintenance: Follow the manufacturer’s recommendations for battery charging and storage to ensure optimal battery performance and consistent power delivery.
• Brush and Track Maintenance: Regularly inspect and clean the brushes and tracks to ensure they are in good condition and provide adequate traction.
• Pool Chemistry: Maintaining proper pool chemistry can help prevent algae buildup and other issues that can reduce suction performance.
• Check for Obstructions: Ensure there are no obstructions in the cleaner’s intake or filter housing that could restrict water flow.

Conclusion

Suction is a critical factor in determining a cordless robotic pool cleaner’s effectiveness. While GPH/LPH provides a useful metric, it’s essential to consider other design features that contribute to overall cleaning performance. Modern cordless cleaners can offer powerful suction comparable to corded models, providing convenient and effective pool cleaning. By following the maintenance tips outlined above, you can maximize your cordless cleaner’s suction performance and enjoy a consistently clean pool.
