the Hoover "Windtunnel" is NOTHING compared to the Apex one-straight path thru the fan into the bag!The Hoover "windtunnel" has all kinds of twists and turns in it-it has to use the monster motor compared to a modest motor used by the Apex.would love one of those Apexes-sounds like one really nice machine!Upgrade it to modern filter bag-good to go!
