Hi! We had Ian from our customer care team put together this quick video: http://youtu.be/cD_Mk_hHXNY with some tips on how to change your belts. Hope this helps!
Hello! The vacuum has a thermal protector sensor that will automatically shut off the vacuum when it is overheated. The vacuum should turn back on once it has cooled down. This can take up to an hour. Overheating is usually caused by a clog or a filter that needs to be cleaned or replaced. Below are steps you may follow to check your vacuum for blockages.
1. Locate the primary filter behind the side grille. Wash the filter, squeeze it out and allow 24 hours to air dry outside of the vacuum. It should be washed about every other month.
2. Locate the secondary filter located in the vacuum base under the paper bag. The secondary filter can be washed in the same manner as the primary filter.
3. Replace the bag if it is full. 4. Remove the hose from both ends. Use a broom stick to gently loosen and clear any clogs from hose.
5. Remove the bottom plate and brush-roll. Use a wooden spoon or something similar to loosen and remove any clogs from the lower hose.
Hope this helps!

Check the belt, if it's a belt driven brush roller. If not, check the bearings of the roller. You may need to replace the brush roller. Take it to a local shop and have it looked at.
If this is a new belt that keeps coming off, then if not catching something in the roller like a scatter rug, etc then the belt isn't tracking true. The pulley may have come loose for one thing, something has to be off to have the belt come off. Does it come off almost right away, or after some uasge?
Either the carbon brushes on the motor need replacing or the thermal cut out is activating. That might be because it is faulty or because there is not enough airflow over the motor.
Overheating motor causing an automatic shutoff. This is most commonly caused by an air passage that is plugged by hair or dirt.
When your Hoover spin scrub is not sucking up water, the most common problem is the clear round cap located on the suction nozzle is not closed. See pic. Also check the rubber cap on the dirty water tank.
The latch at the bottom of your vacuum cleaner. The problem is that 'React' seems to be a range of cleaners.
