Brand new vacuum. It makes a loud screetching whistle as it vacuums. Makes my ears ring after I'm done. I've tried taking everything out and putting it back, like the filter and all it's parts, the brush, moved around the belt, saw nothing caught in it anywhere. Even turned it on without the bag part on it and it still screetched. Please help before I go deaf.

If you let it continue, you will have a piece of junk. You take the bolts off holding the motor cover on and you lubricate the upper bushing with oil. They are oil impregnated bushings and will soak up a thin type oil best and last longer. Use 10W or 3-in-1 oil or Marvel Mystery oil.
if this sounds like an airplane taking off, then for your hoover U5288-900 it will have to be the fan that is inside the motor compartment. i have looked at hoover.com and cannot find the part num. to the fan, but i know that you can replace it. you can also get one from your local vac shop. if you do get a fan for this and need help in changing it. write me back if you get stuck. hope this helps
I would say you either have something stuck on the impeller or there is a piece of paper or something stuck inside the hose. its not clogging the hose but when the air passes by it. It is making that noise. If you find nothing you may need a repair. May have a bad bearing in the motor. Actually you can also try inspecting the brush on the head. It removes easily from vacuum and should spin freely and quietly.
when you take out the canister to dump it, there is a filter on the bottom.. take off and shake it out then put it back.. there''s also one on the top!!so when you replace thaton..look directly above that surprise anothe one do the same to that one and wholah like new
