Why would a Hoover Windtunnel have no suction?
It could be clogged at the head or throat, or you might have a hole in the hose. Unplug the hose; if you're getting suction where the hose plugs in then the problem is in the hose or the head. If you're not getting suction where the hose plugs in then the problem is in the body, probably the throat. If the problem is in the hose or head, detach the hose from the head and check for suction at the end of the hose. If there's not suction there, then you've got a clog or a hole. If there is suction there, then you've got a clog in then head.
