There is not enough suction in the hose to run the upholstery tool, and there isn't really enough suction to pick up a paper clip throught he lower unit. The belts are fine, I've taken the panel off the back and exposed the plenum where the hoses come together and there are NO clogs anywhere to be found (I've completely exposed the dirt path from the hoses to the dirt collector). Is it possible that the blower itself has been damaged enough so that the machine is not generating enough VACUUM? This machine used to, but it doesn't **** anymore.
There's also the possibility that the fan/impeller has stripped loose from the motor shaft and is basically sitting there while the motor turns. Also, you may have broken vanes on the fan/impeller that will drastically reduce the suction. Replacement fans aren't very expensive to replace if it's stripped or broken.
Did you check the dirt inlet by the brush roll, filters ok, they should be replaced once a year. Belts can look fine, but if they are a few months old, I am sure they have stretched and the brush roll will not turn like it should under load. It is possible that the motor isn't running up to speed, thereby reducing suction.

Thanks Plantsman,
This was my thought as well. My next step is to figure out how to easily get at the motor itself and either replace those 'inexpensive' vanes, or replace the motor itself. Any suggestions?
