Hoover UH72625 vs UH72630 what’s the difference?

  • The difference between Hoover UH72625 and UH72630 is the Cord Length.
    The UH72630 has a 40-foot power cord versus 30-foot on the UH72625.
  • About the Air Valve Dial.
    Both the UH72625 and UH72630 used to have an Air Valve Dial on the side which allows you to switch suction between Floor and Hose. Turn dial to HOSE position for cleaning with hose and/or tools, turn dial to FLOOR position for general floor cleaning through nozzle.
    But the new versions of UH72625 and UH72630 no longer have the air valve dial. You will have to go to the bottom of the vacuum to detach the hose if you want to use attachments.
    Don’t be fooled by the images on the product box and the manual, though they show the air valve dial, the actual vacuum did not have that function. There are users that bought the UH72625 and UH72630 complained this false advertisement. Seems the manufacturer have not updated the package yet.
