Detail *100% new, high quality *Material: PP, PA (rods), nylon, iron *Color of the rods: white or yellow (random) *Length of the pole (1 piece): 400mm *Brush head sizes: 100mm, 150mm, 200mm *Extendable length options: - 6-piece rod set: 2.3m (7.6 feet) - 9-piece rod set: 3.5m (11.5 feet) - 15-piece rod set: 5.8m (19 feet) - 18-piece rod set: 7m (23 feet) *Regular cleaning of lint and debris from pipelines helps maintain airflow and reduces the risk of fire in dryers. Cleaning chimney deposits helps prevent blockages that may lead to poor ventilation and potential carbon monoxide buildup. *One-time purchase for repeated use – clean whenever needed. *Multi-functional design suitable for cleaning fireplace pipes, chimney pipes, and dryer vents. Not recommended for use with flexible foil ducts, as it may cause damage. *Compatible with a cordless electric drill. Attach the rod, rotate clockwise, and move back and forth to clean pipes effectively. How to choose the pole length: *Available lengths: 400mm, 410mm, 570mm, 600mm *Shorter poles offer greater stiffness. *Hardness comparison: 400mm PA rod > 570mm PA rod > 410mm PP rod > 600mm PP rod *Quality comparison: 400mm PA rod = 570mm PA rod > 410mm PP rod = 600mm PP rod *Recommended: 400mm PA rod and 570mm PA rod for optimal performance Resilience comparison: *High resilience rods: Made from superior materials with strong recovery after bending. Less likely to break under demanding conditions. Ideal for ducts with multiple bends (e.g., more than 3 elbows). *Standard rods: Suitable for simple, straight ducts. May break under high stress. Special notes: *Newly manufactured PA rods may feel stiff. Exposure to air for approximately one month allows moisture absorption, resulting in increased softness and elasticity. Do not store sealed; allow airflow for natural conditioning. Do not soak in water, as it may affect rust protection on connectors. *The rods in this product are made of PA material, ensuring high quality. *Rods are shipped in white or yellow color at random. *Actual pole length ranges from 400mm to 415mm. How to use: 1. Connect the required number of rods. 2. Attach the brush head to the rod. For drill use, connect the hex adapter. 3. Begin slowly, cleaning 2–3 feet at a time. Pull the brush back to remove debris. Avoid pushing debris vertically; horizontal cleaning may be effective. 4. Have an assistant operate the drill while you guide the rod. Move in and out gradually, retrieving debris regularly. 5. Wear a mask – dust and odors (such as fabric softener) may be present. 6. Always rotate the brush/rod assembly clockwise only. Reversing direction may cause detachment inside the duct. Warnings: *Do not force the brush/rod assembly through the duct. If resistance occurs, pull back slightly (while maintaining clockwise rotation), then proceed slowly. *Avoid bending the rod when using with an electric drill. If bending is necessary, do not exceed 30 degrees and operate at a very low speed to prevent damage. *Remove any unused rods when the total length exceeds the required length. Excess rods may twist and become damaged due to drill rotation. Specifications: *Please note that slight variations in dimensions may occur due to manual measurement.
