This is a known fact...
A good Direct Air vacuum such as Kirby, Royal metal upright, or the Riccar Tandem Air vacuum will outclean and out perform ANY Bagless upright vacuum ever made.
You might like to see the dirt your bagless vac pulls out of your carpet, but the fact is that a good Direct Air vacuum will get all of the dirt your cheap bagless vac leaves behind in your carpet. This is the fine dirt and sand that destroys your carpet when walked on by slowly grinding away the fibers of your carpet. There is not a bagless upright vacuum ever made including Dyson, that can pull more dirt out of a carpet than a good Direct Air vacuum!
