Why do the brushes in a vacuum cleaner spark?

There is a reason to worry if the brushes of the electric motor of the vacuum cleaner spark, because this means the presence of a defect that can shorten the life of the vacuum cleaner. There are quite a lot of reasons for this phenomenon.

Reasons for sparking vacuum cleaner brushes

Why do the brushes in a vacuum cleaner spark? Let's look at the main reasons in this article.

Wrong angle

Attention! If the equipment is used for a long time, they may become dislodged. Therefore, it is necessary to ensure that there is no distortion. Of course, all types of vacuum cleaners have different brush mountings, but, in general, all types have a common device - a holder. It is attached with two screws.

Closure

Do the vacuum cleaner motor brushes spark strongly? If you hear occasional pops; you notice that sparks are flying around the circle; If you observe blackening, then this is definitely an interturn short circuit. Alas, it is unlikely that a person without experience in this area will be able to cope with this problem. Therefore, it will be difficult to fix the breakdown yourself.

Wear of parts

Reference! When purchasing a vacuum cleaner, it is better to immediately take spare parts for the vacuum cleaner.

Poor contact

People most often encounter this when installing new brushes. They shouldn't be loose. You need to make sure that the spring is pressed tightly against the manifold. This can also occur due to the presence of dust, so you should clean the contacts well.

Dirt entry

Excessive tension causes more friction and dirt can form. Long-term use of carbon deposits promises rapid equipment breakdown.

Ways to fix the problem

1. If the angle of inclination is incorrect: it is necessary to carefully examine the surface of the nodes. Next, adjust the position using screws.
2. If shorted: it is best to replace the motor. Or seek the help of specialists by contacting a repair center.
3. If the brushes are worn out, then you need to find the brush holders, having first disassembled the engine, and replace the brushes yourself with new ones.
4. If the contact is poor, you can let the vacuum cleaner run for more than 15 minutes at neutral speed.
5. Sliding contacts must always be kept clean, but if contamination occurs, carbon deposits must be immediately removed using sandpaper or fine plaster and degreased.
