Product Summary Over time, your dryer vent fills with lint that sneaks by your dryer's filter. Fires can occur when lint builds up in the dryer or in the exhaust duct. Lint can block the flow of air, cause excessive heat buildup, and result in a fire in some dryers. The Pro-Series is designed for the homeowner by a leading manufacturer of professional duct-cleaning equipment. It effectively removes dangerous lint buildup in almost every type of dryer vent system, and it's easy to use with your cordless drill.
