Yes possibly disconnected, check behind the basement wall to be sure the hose is connected.

You can also check inside the vac box in the basement... i know that ours was filled with papers, plastic bags, and extra bags.. it was hardly sucking.. That is where they store ALL the lititure for it....
Before I would take a basement wall section down, I would remove the cover to the Dirt Devil vacuum and make sure there is a bag installed. Most everybody still has the new package of bags inside. Never installed. Cover pops on and off. If not the filter itself, then remove a basement wall section.
My vacuum system had such a sharp turn in the hose between the wall plug in and the vacuum unit, it would get clogged up very easily.
I cut some of the hose and made a slighter radius, no more problem with clogging up.
