A powerful portable pool vacuum pump can be highly effective for keeping pools clean without the need for a permanent installation. Here are some features to look for in a high-quality portable pool vacuum pump:

1. High Suction Power: Look for a model with strong suction capability, often specified in gallons per minute (GPM), to ensure it can handle large debris and provide thorough cleaning.

2. Portable Design: Lightweight and ergonomic handles make it easy to move the vacuum around. Some models come with wheels for easier mobility.

3. Durable Materials: Look for corrosion-resistant materials, such as stainless steel or high-quality plastic, as pool vacuums are constantly exposed to water and pool chemicals.

4. Self-Priming Capability: This feature allows the pump to start working without the need to be filled with water beforehand, making it convenient and quick to set up.

5. Filter Compatibility: Many portable pool vacuums come with a built-in filter bag, which helps trap debris before the water is recirculated back into the pool. For deeper cleaning, some units allow connection to the pool’s filtration system.

6. Multi-Surface Cleaning: Some models are compatible with various pool surfaces, from concrete to vinyl, ensuring versatility in different pool environments.

7. Adjustable Flow Rate: Adjustable speeds or flow rates can be helpful for different cleaning requirements, like quick clean-ups or thorough, deep cleaning.

8. Battery or Electric-Powered Options: Choose one that suits your needs. Battery-powered pumps offer better portability and are cord-free, while electric-powered pumps can provide more continuous power for larger cleaning tasks.

9. Noise Level: A quiet-running model is preferable, especially if you intend to use it during poolside gatherings.
