LintCatcher easily captures all of the loosened lint from the dryer vent when utilizing LINTEATER dryer vent cleaning systems. Simply attach the LintCatcher bag to your exterior vent hood, turn on your shop vac, blower or clothes dryer and begin rotary brushing the vent system. The loosened lint exits the vent and is neatly collected in the LintCatcher. It works easily when cleaning from the outside or from the inside.
