Yes, I can admit that every cleaning method has a clear advantage and disadvantage. Although I would love to make every consumer and or potential customer our customer, the reality is that many factors affect where
a consumer or potential customer turns to for their indoor air quality needs. The power
vacuum/air sweep method involves a powerful large diameter vacuum hose generally ranging in diameter from 8” 12” that moves anywhere from 3000 CFM – 26,000 CFM cubic feet per minute of negative air draw depending on the type of power vacuum machinery being used. Typically speaking, having power vacuum machines that moves anymore that 10,000 CFM is foolish, considering the fact that all ductwork is rated for a set amount of CFM based on the size of the ductwork through external static pressure ratings, velocity and ambience. I do have to admit that the more power a vacuum has, the cooler it is to witness, though. The power vacuum hose is typically installed into the ductwork via a circle cut out which allows for the power vacuum to put the entire side of the ductwork under a complete and sound vacuum draw.
