Trash bag with air or vacuum to suck line through conduit 'with wires' in it?

Our AIR-TIP Dust Collector collects dust as you work with its rubber seal that maintains suction to a wall for less cleanup time later. After connecting the dust collector to a wet/dry vacuum, it uses the vacuum's suction so you can attach it to a wall for hands-free work. You can cut or drill above the funnel design while the vacuum is on to capture more debris.
