Over time, your dryer vent fills with lint that sneaks by your dryer's filter. Avoid the fires that can occur when lint buildup blocks the flow of air, causing excessive heat buildup by keeping your dryer vent clear with the LintEaterTM. Designed by a leading manufacturer of professional duct-cleaning equipment, the LintEater Dryer Vent Cleaning System effectively removes dangerous lint build-up in almost every type of dryer vent system, and it's easy to use with a shop vac or cordless drill (sold separately) or even your dryer's air. The LintEater Dryer Vent Cleaning System comes with a variety of brushes, extension rods and adapters to clear your ducts thoroughly, regardless of whether you have a metal, foil or white vinyl dryer vent. The rotating action of the auger brush and flexible rods will traverse the multiple turns that are common in most vent systems. The included adapters allow you to use the air from your dryer or a shop vacuum/blower to remove the lint from the vent completely while rotary brushing.
