The LintEater LintCatcher captures loosened lint from the dryer vent while rotary brushing with the LintEater system. Simply attach the LintCatcher bag to the exterior vent hood, turn on your blower or dryer and feed the auger brush and rods through the zippered opening to begin rotary brushing the vent system. As loosened lint is blown out by the blower or air from the dryer, it is collected in the LintCatcher, making the job clean and hassle-free. Works great when cleaning from the inside or the outside.
