This video compares the durability of single-speed and variable-speed pool pumps. The speaker explains how single-speed pumps are susceptible to damage from insects, small animals, and rainwater due to their open vents. Variable-speed pumps, on the other hand, have a sealed design and an external fan for cooling, making them more resistant to these issues.
