If there is no suction, check the filters, if they are clean then there has to be a clog either in the hose or in the inlet down by the brush roll. See if there is suction at the hose end. If there is, then it is clogged down lower. Are you sure that the brush roll is turning when it is on the carpet? For a manual, go to, put on your model number, if one is available, you can down load it.

Hoover Windtunnel spits dirt back out the back

Your problem sounds to be an obstruction in the foot (lower body) of the windrummel. Most all windtunnel's have a second cavity for suction to go over the top of the roller. When you remove the bottom plate, next remobe the belt and roller, under the roller will be a removable cavity, take it out. remove the dirt and clean out any debris. also check the suction path connecting hose. if your belt has not been changed in the last 12 months, I would recommend changing that as well.
