GPH (gallons per hour) measures how much water your handheld cordless pool vacuum can move in an hour. This flow rate is a critical factor in cleaning performance, battery efficiency, and ease of use. 💧 Whether you’re maintaining a small spa or a large in-ground pool, understanding GPH can help you clean more efficiently and effectively by matching power to task and avoiding wasted time or battery life.
What Is GPH and Why Does It Matter?
Definition and Relevance
GPH shows the volume of water your vacuum moves each hour, indicating suction strength and debris capture capability. Knowing this figure helps you compare models and choose one that meets your exact needs.
Impact on Cleaning
A higher GPH means stronger suction, pulling in more debris per pass and reducing the number of passes needed. 🌪️ Low GPH may leave fine particles behind, increasing cleaning time and effort.
Battery and Performance Balance
Cordless vacuums rely on battery power. Too high a GPH drains the battery quickly; too low makes cleaning less effective. Understanding this balance means you can finish cleaning in one charge while still achieving a spotless pool.
⚡ Key Insight: Aim for a GPH that balances suction power and run time for optimal results.

How to Match GPH to Your Pool and Vacuum
Check Manufacturer Specs – Ensure the vacuum’s GPH matches your pool’s needs, not just what sounds powerful on paper.
Consider Pool Size – Larger pools require higher GPH to speed cleaning and avoid multiple sessions. ⏱️
Account for Debris Type – Heavy debris like leaves and sand calls for higher GPH, while fine silt may be handled at moderate levels.
Surface Sensitivity – Vinyl or delicate surfaces need moderate suction to avoid damage.
Run Time Requirements – Match GPH with battery life so you can complete cleaning in one charge without rushing.

Yes—higher suction requires more energy, which shortens run time. Consider a model with adjustable settings to adapt to different cleaning needs.
How do I know my vacuum’s GPH?
Check the product specs or user manual for accurate information, and verify with manufacturer websites if unclear. This ensures you’re basing your choice on reliable data.
Does GPH affect cleaning time?
