It may begin with sluggish movement, lack of traction on the pool floor, and inability to climb walls. Don't wait until the cleaner begins to malfunction. Get ahead of your pool cleaner maintenance with a pair of , high-performance timing tracks. COMPATIBLE WITH NUMEROUS DOLPHIN ROBOTIC POOL CLEANER MODELS - Perfect for models that require 2 tracks (one on either side) including: Dolphin DX, Dolphin Explorer, Dolphin Advantage, and more. REPLACE TIMING TRACKS IN PAIRS - It's tempting to just replace the track that looks worse for wear. However, the other timing track will soon follow. Deterioration isn't always obvious, especially for timing tracks that have worn out gradually and evenly. As a rule of thumb, timing tracks that are over 2 years old should be inspected for wear and replaced as needed. Please rinse and clean every 4-6 weeks for the best performance.
