A duct cleaning apparatus for cleaning ventilation ducts in a household environment comprises a typical household or light industrial vacuum cleaning having a sealed container, a blower having suction and exhaust, a first flexible hose attached to the suction port and a second flexible hose attached to the exhaust port. The hoses are adjacent and parallel to each other and fixed together using a plurality regularly spaced elastic bands. A blower nozzle and a suction nozzle are adjacent to each other and placed in a duct for cleaning. The blower nozzle directs a jet of air into the vacuum zone of the suction nozzle thereby agitating dirt and debris within the vacuum zone for a more efficient cleaning action.
