[Premium Materials] Replacement timing tracks for Dolphin pool cleaners help maintain optimal performance and extend the life of your robotic pool cleaner. These tracks are designed to keep your pool cleaning system operating safely and efficiently. Improve the Performance of Your Robotic Pool Cleaner – Worn tracks can lead to slow movement, reduced traction on the pool floor, and difficulty climbing walls. Address these issues early by replacing worn timing tracks before malfunctions occur. Replace Timing Tracks in Pairs – While it may be tempting to replace only the more worn track, it is recommended to replace both tracks at the same time. Uneven wear is not always visible, especially with gradual, consistent wear patterns. As a general guideline, inspect timing tracks older than two years and replace them as needed to ensure balanced performance. Color: As shown. Material: PP.
