Durable nylon brush head: made from high-temperature resistant, anti-aging nylon to stay effective over repeated use. The bristles are firm enough to abrade and remove hardened soot and creosote from internal chimney or duct surfaces. Complete rod set, multiple lengths: available in sets that include 6 / 9 / 12 / 15 / 18 nylon rods plus one brush head and one hexagonal connector rod. Rod lengths are 41 cm or 61 cm (easy to assemble/disassemble) so you can build the reach you need by connecting rods. Power-cleaning performance: attach the hexagonal connector to a power drill (electric drill not included) for faster, more thorough cleaning than manual brushing. Power cleaning removes more dirt while being gentler on smoke cabinets and stainless-steel liners compared with harsh metal tools. Flexible, extendable reach: rods are flexible enough to pass through bends and transition pieces. Connect multiple rods to reach deep linings, long vents, or high chimney stacks without climbing into unsafe positions. Safety and dryer performance: use the brush to clear lint, dust and pellet buildup from dryer hoses and vents. Removing these obstructions improves dryer efficiency and reduces the risk of overheating and fire. Key attributes Material: high-temp resistant, anti-aging nylon brush head Kit contents: 6/9/12/15/18 nylon rods (depending on chosen set), 1 brush head, 1 hexagonal rod Rod lengths: 41 cm or 61 cm per rod (sections can be joined) Power tool compatibility: designed to connect to standard drills via the included hexagonal rod (electric drill not included) Function: removes soot, creosote, lint, dust and other deposits from chimneys, ducts and vents Practical use scenarios 1) Chimney and flue cleaning: Join multiple rods and use the brush head with a drill to dislodge creosote and soot from internal chimney stacks and flue liners safely from the roof or from inside the fireplace. 2) Dryer vent maintenance: Feed the brush assembly into a dryer hose or external vent to remove lint and improve airflow, lowering dry time and fire risk. 3) Kitchen exhaust and ductwork: Clean range hood ducts, smoke cabinets and stainless-steel liners to remove grease and soot buildup without aggressive metal scraping. Notes The included brush head is intentionally abrasive to remove deposits; take care on highly polished or fragile finishes. Electric drill is required for powered operation but is not included in the package.
