1. Take a new replacement strip and position it with the S logo facing downward.
2. Hold the tool handle with one hand and the cleaning head with the other.
3. Use your fingernail to gently pry open the seam of the plastic cover in a lever motion.
4. Insert and fold the new strip inward, then secure it firmly onto the cleaning head.
5. Press the plastic cover firmly closed, and fasten all buckles tightly to ensure a secure fit.
6. Note: Users with weaker hand strength may need to apply extra pressure to fully close the plastic housing after replacing the strip.
