Pentair / Letro – Pressure Side Pool Cleaners, Letro Cleaners and Replacement Parts

Pentair / Letro refers to Pentair’s line of pressure-side pool cleaners and legacy Letro cleaning systems, widely used in residential pools for automatic debris removal. Letro was a well-known brand in pressure-side cleaning technology, and its products are now supported under the Pentair umbrella. These cleaners remain popular for their reliability and strong cleaning performance.

Pentair / Letro specializes in pressure-side pool cleaners, cleaner parts, debris bags, hoses, wheels, and internal components. Their product lineup includes cleaners that connect to a dedicated pressure line or booster pump to sweep, vacuum, and collect debris from pool floors and surfaces. These systems are designed for efficient, automated cleaning.

Pentair / Letro products are known for durability, powerful cleaning action, and long service life. Pressure-side cleaners are especially effective at handling larger debris such as leaves and dirt without overloading the pool’s filtration system. Pool owners choose Pentair / Letro for reliable cleaning performance and easy maintenance.

To select the correct Pentair / Letro component, it’s important to identify your cleaner model and match part numbers such as bags, tires, or internal assemblies. Many Letro models are legacy systems, so cross-referencing with Pentair replacement parts is often required. Choosing the right part ensures proper cleaner function and optimal debris removal.
