FROG Water Care Experts Glossary of terms

Any number of devices that use suction to collect dirt and debris from the bottom and sides of a pool or spa. Most commonly, it is a vacuum head with wheels that attaches to a telepole and is connected to the suction line usually via the opening in the skimmer. It must be moved about by a person, and debris is collected in the filter. See also Automatic Pool Cleaner.

Used to vacuum debris from the floor and slopes of the pool. It attaches to the vacuum head on one end and to the vacuum plate on the other.

Provides a vacuum-sealed connection for the vacuum hose, allowing debris to be caught in the skimmer basket rather than the pump strainer basket.

A fitting that consists of a tube constricted in the middle and flared on both ends. While passing through the constriction, a fluid's velocity will increase while its pressure will decrease. Placing a tube or pipe at the constriction point creates a vacuum. Fluid or air can then be drawn in through the tube. A hydro-therapy jet draws air in and mixes it with the water using this principle.

The vinyl liner is the product that covers the walls and base of the pool and holds in the water. The liner has a beaded edge that locks into the coping. The heavy vinyl liner is durable, easy to clean, and generally maintenance free through all kinds of weather. It can be specially treated to resist bacteria, typical chemical levels and ultraviolet rays.
