How Does a Pressure Pool Cleaner Work?

Published in Pool Cleaning Technology 2 mins read

A pressure pool cleaner effectively cleans your pool by using the power of water pressure to both move itself and collect debris, primarily through a clever mechanism known as the venturi effect.

The Core Mechanism: Water Pressure and Propulsion

Pressure cleaners operate by receiving pressured water from your pool's dedicated booster pump or return line. This incoming water isn't just for cleaning; it serves as the primary propulsion system. The cleaner is designed to push water to the cleaner, which in turn propels it along the pool floor and occasionally up the walls, ensuring comprehensive coverage of the pool's surfaces.

The Venturi Effect: How Debris is Cleaned

The true cleaning power of a pressure pool cleaner lies in the venturi vacuum that the pressured water creates.

Here's how the venturi effect cleans your pool:

  • Pressured Water Flow: As water is pushed through a constricted part of the cleaner, its speed increases significantly.
  • Pressure Drop: This increase in water speed causes a corresponding drop in water pressure within that area, creating a powerful suction, or "venturi vacuum."
  • Debris Collection: The venturi effect forces leaves and debris up from the pool floor and into the cleaner's collection system.
  • Debris Containment: The collected debris is then directed into a catch bag, net or screen attached to the cleaner, preventing it from recirculating back into the pool.

Essentially, the cleaner doesn't vacuum in the traditional sense using a motor; instead, it leverages the physics of water flow to generate a strong suction that lifts and captures unwanted material from your pool. This innovative approach makes pressure cleaners an efficient choice for keeping your pool sparkling clean.
