Question about Hoover UH70210 Bagless Upright Vacuum

Open Question

My brand-new Hoover T-Series Windtunnel is making a knocking noise as the belt spins and the roller clutch doesn't disengage as far as it should. Its worrisome only because I just pulled it out of the box and as far as I know there aren't any adjustments that should be made. Or can be made for that matter. Any suggestions?

SOURCE: Hoover WindTunnel Canister: Roller brush motor not turning

These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.

SOURCE: Hoover Windtunnel shuts off

Sounds like you have a clog, which is a fairly common problem with these.

Check the air inlet immediately aft of the brushroll for clogs, then make sure the main wand and hose are also clear. If you have the machine on, check at the end of the hose for suction. This is a fairly common problem for all uprights with tools on board. Their airflow is very low, so they tend to clog up easily and then overheat the motor.

SOURCE: brush roller on windtunnel won't spin

It sounds like you need to replace the actuator arm or the cable to it. Look for Hoover part 43143046 for a start. I've got a similar problem.

SOURCE: auto brush on hoover windtunnel doesn't spin anymore

I have a Windtunnel S3765 with the same problem - and it has very little use so I'm confident it isn't wear. I find that the wheels do not raise the agitator brush sufficiently high to reduce the drag caused by excessive contact with the carpet. If I raise the front a bit the brush spins as it should. It also works if I take the housing apart and use it without ..... but this is tricky.

Unfortunately I haven't figured out a way to hold it up efficiently. I am toying with afixing something to the bottom of the housing to raise the front enough to give the brush a little more room.

Hoover Windtunnel model U6485200B troubleshooting brush not spinning


Hi! The brush-roll feature needs to be engaged for the belt to tighten, so when checking the belt it will appear to be loose. Be sure you have replaced both belts on the vacuum with genuine Hoover parts. This unit takes belt 38528034 and 38528035. Also, make sure the vacuum is on carpet mode. Follow the link to view the instruction manual which provides instructions and illustrations on changing the belt to be sure it is assembled properly.

Changed belt. have burning smell


Take it back apart, check it again. Check the plastic where the belt is running for burnt spots. Also check the brush roller sometimes the tension from a new belt can finish off what was left of the bearings and cause the plastic end caps and roller to melt. Pull out the roller and try to spin it while holding the end caps. If it doesn't spin or spins hard there's your smell. Most times when the rollers go bad they break the belt. Replace the roller if necessary Make sure the roller is in correctly and flush and that the bottom plate goes on easily.


Good Luck

This vac has 2 belts. If both self propel and roller not spinning then most likely it is the wide flat belt broken or off. 4 screws on the bottom should gain you access to the belt area. another issue for this model series is a worn pulley on the roller, a new belt when inserted around the roller should be even with the top of the pulley groove.

Describe how to replace belt on hoover windtunnel bagless


If you turn the vacuum so the bottom is facing up you will see the base plate that covers the roller brush. There will be four screws (usually phillips head), remove the screws and the base plate will lift off. You now have access to the roller brush and belt. Lift the roller brush up and remove the old belt. Place one end of the new belt over the motor shaft and the other end over the roller brush and put the roller brush back in place. Now simply replace the base plate and you're done! This models requires Hoover belt # 38528033 (single) or Hoover belt #40201160 (2 pack). You can get this belt at www.vacbelts.com.

Replaced belts and brush roller will not rotate.


check to see if the spindle (small pencil-thin metal rod) is spinning where it projects from the motor. the belt wraps around this rod. if the rod is spinning when the vac is turned on your brush roller could be jammed. the bearing in the far sides of the brush roller frequently pick of long threads and hair and will stop the brush roller or the bearings sometimes overheat when worn and plastic will melt in this area causing stoppage.

The V belt usually wears down first. Remove the roller and belt to visually check for wear and belt material in the roller pulley. I would change the flat belt as well. Also, replace the cord if any wires are exposed

Hoover very noisy after new belt installed.


what is the belt # you have installed (generic)? Yes, there are problems with using generic belts on Hoover Vacuums. If you have noise I would suspect the roller, and replace it. the cost is about $25 and is something that you can install. The newer type are mande of wood and are very quiet.

Brush on vac


I don't know how old your machine is, but the belt should be changed at least once a year and you should check to make sure the roller spins freely. There are bearings at either end of the roller and they will become contaminated with dirt and hair after a while and will need to be serviced. A new belt will help, but won't last if the roller is in need of service.
