It may have overheated from a restriction or clog. If so it will come back on after it cools down.

Hello! If your belt keeps coming off, this usually means the belt is stretched and needs to be replaced. The Dirt Devil Breeze takes a Dirt Devil style 4 belt. Follow the link below to purchase the replacement belt. Hope this helps!

Style 4

Hi there! The vacuum is equipped with a thermal protector sensor that will automatically shut the motor down if it reaches a certain temperature. This is usually caused by either a clog or a filter that needs to be cleaned or replaced. Make sure you check both the hoses for clogs and clean all filters properly. If a filter is really dirty it may be time to replace it. Hope this was helpful!

normally, the vacum has a height adjuuster. try turning it to higher level

Dust blows out of the filter vent is usually caused by a plugged filter drop the filter door on the back, replace or for a temporary fix blow out the filter

needs to be cleaned, at least the filters in any.
