Hi My bissell proheat 2x 9500 is making a loud noise when the brushes are moving. I replace both belts and cleaned the brushes. Can you think of anything else it could be.

Hello there,
Try using other brush attachments, as broken bearings in a brush attachment will cause noise. If these troubleshooting techniques do not work, you may need to service the engine.
Remove the filter and bag of the machine and make sure that they are not clogged or full of debris. Clean any filters according to the instructions for your model or replace the bag. Excessive debris will make the engine run noisily.
Inspect the hose of the vacuum and remove any large debris that may be clogging the inside of the tube. Large amounts of dust, as well as stones or other hard materials that bounce, may cause a loud noise in the engine.
Remove the housing that conceals the engine of your machine and inspect the fan for damage or clogging. Remove any dirt or debris that may hinder the movement of the fan. Inspect the fan for any damage such as bent or excessively sharp blades. Replace the fan blades as needed; contact your vacuum manufacturer if the fan is damaged. The replacement part will include instructions.
Tighten the fan with a ratchet if it is loose on the assembly. A loose fan will make a rattling sound as the motor revs.
Wipe dirt and dust from the frame of the engine. Large quantities of dirt or dust around the motor can cause it to overheat, which can cause vibration and loud noise.
Look for corrosion around the engine. If the engine is corroded, it must be replaced.
Grease the bearings of the engine if you hear a grinding noise from the vacuum. Greasing is often performed through ports in the engine, or by removing the bearings. However, the actual greasing method is model-specific. Consult your owner's manual or send the vacuum to a service professional for this service.
Inspect the inside of the vacuum cleaner for other worn parts or broken pieces. Worn or broken pieces can cause loud noises to occur. Remove the broken part and order new materials from the vacuum manufacturer or take the machine in for service.
Hope this information was helpful to you. All the best. Elect_Comp

Do not turn on again. You have an obstruction in the fan . You will need to remove the motor from the lower housing, dismantle the fan cover and remove the obstruction, possibly replace the fan as well.
The lower housing plate can be removed revealing a set of clamps around the motor hosusing which will in tun release the motor from the base of the vac.

Loud 'drilling' noise from motor area when turned on.

Sounds like bad bushings/bearings in the motor -- need to replace them.

Hoover started to make loud noise

It sounds like a bad motor. Take it to a local vac shop and they should be able to order the motor for you.

Cyclonic 14.4 volt DustBuster started loud humming noise?!HELP

Ours began making a hideous grinding racket and then quit altogether. Upon disassembly, I found a plastic guard protecting the fan that had warped and was preventing the motor from turning at all. Your problem may be related to the same plastic guard. I removed mine and now all is well...I think. If only I could find a replacement for this little guard. Every online parts distributor I've seen will only go as far as selling filters and prefilters.

Bissell 8990 CleanView Bagless Upright - Loud noise

Sounds like maybe your motor went bad, part # 2031052. Would sell for about $60. When the bearings go bad, they can be real loud as well if the fan on the motor when it gets damaged.

Loud noise

When the motor bearings start to go bad, they will make a loud noise. Some motors if a piece broke off of the fan, then it also will make a loud noise. You may have to replace the motor.
