Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

All fo a sudden, no suction, motor runs fine, no clogged tubing.


Answers :

Be sure the upper attachment hose is inserted firmly into the lower hose into the nozzle. Check for suction at the end of the hose, and if there is no suction there must be an obstruction in the hose, or the filter inside the bag compartment is plugged. Be sure the brush is turning when the handle is released.

Hoover Windtunnel My Hoover Windtunnel is 3 years old. It worked great until yesterday when it lost all suction. I have followed the manual to trouble shoot any possible clogs and could find none.

I bought a Kenmore canister vacuum, model 116, in April 2007. This morning, the sound of the motor suddenly began to deepen, and I began to lose suction. Normally, if something is clogging the hose, the motor will wind up to a higher pitch, not a lower one. The filters are clean, the bag is empty, and I can't detect anything lodged in the hose. If this were a car's engine, I would say it's "lugging down". Any pointers?
