Replacing the hose can eliminate aging leaks, making airflow more stable, maintaining suction in good condition, and making daily cleaning more efficient without repeatedly sweeping the same area. The replacement hose is more flexible, less likely to crack when bent or stretched, and can easily reach under furniture, corners, and other tight spaces, allowing for thorough cleaning and easier use. After replacing the hose, the air duct is clean and unobstructed, reducing dust buildup, keeping the home environment cleaner, and enhancing the overall cleaning experience. Replacing the hose can reduce the main unit's vacuum loss, lighten the motor's load, decrease abnormal operating pressure, and help extend the overall lifespan of the vacuum cleaner.
