What causes my vacuum cleaner to smell like burning?
The burning smell in your vacuum cleaner can often be attributed to the motor overheating. When the vacuum is overloaded, whether due to a clogged filter or a full dust container, it forces the motor to work harder than necessary. This excess strain can cause the motor windings and bearings to heat up, resulting in that unpleasant burning odor.
Another common cause is debris that has become lodged in the vacuum’s rotating brushes. Hair, string, or other materials can wrap around the brush rolls, causing them to stop turning freely. This grinding friction can generate heat, which contributes to the burning smell, as well as possibly damaging the brush motor over time.
