The weird noise at the beginning of vacuuming with a Hoover WindTunnel vacuum that features self-propelled motion is often due to the motor engaging and the self-propulsion system activating. This initial sound can also result from the vacuum adjusting to different surfaces or the brushes starting to rotate. Additionally, any debris caught in the brush roll might contribute to unusual noises at startup. If the noise persists or seems abnormal, it may indicate a need for maintenance or potential blockage.
To replace the belt on a Hoover self-propelled WindTunnel vacuum, first unplug the vacuum and lay it on its side. Remove the bottom plate by unscrewing the necessary screws, then take off the old belt from the motor shaft and brush roll. Install the new belt by looping it over the motor shaft and then onto the brush roll, ensuring it is properly aligned. Finally, reattach the bottom plate and screws, and your vacuum will be ready to use.
