Abstract: A portable air duct cleaning system comprises a cleaning assembly, including a hose, motor and brush; portable power and control box; and remote control. The cleaning assembly may include a vacuum system connected to the hose, having an opening, with a motor driven brush unit positioned near the opening for vacuuming particulate matter dislodged by the brush unit while the brush unit traverses the air duct. The vacuum system may be part of a carpet cleaning system.

Abstract: A mobile air duct vacuum provides an efficient method for cleaning HVAC ductwork in nearly any location. Upper and lower sections of circular cross-section are removably connected defining an air passageway. Said upper section houses 1st, 2nd and 3rd stage filters for insuring that “dirty” air passing through the system is thoroughly cleaned. Said lower section houses an air directional unit, blower wheel and motor. The motor causes the blower wheel, having spaced blades, to rotate and draw air from within the subject ductwork and through the filters thereby effectuating the cleaning. Thereafter, the clean air passes through the air directional unit into the blower wheel where it is re-directed to the surrounding environment through vents in the lower section. Wheels and a handle provide for a mobile air duct vacuum. To facilitate transportation of the vacuum the upper section and lower section can be readily disjoined.
