The 12V 25-Point LED Star Floor Kit with 50' Fiber by S.R. Smith is designed specifically for gunite (concrete) pools and is installed flush with the pool surface, sealed beneath plaster or finish material. Once properly installed and cured, the fiber optic fixtures are encased and waterproof, making them safe for use with standard pool vacuum cleaners, including both manual and automatic types. That said, here are a few precautions to keep in mind: 🧽 Avoid abrasive brushes or metal wheels that could scratch or chip the plaster around the fiber tips. 🌀 Suction-based vacuums are generally safe, but avoid lingering over the fiber tips to prevent potential wear. 🛠 If the fiber tips were not properly trimmed or polished, they may be more vulnerable to damage—so a quick inspection is wise before vacuuming.
