Experience informs us that transformers and many new models of the best upright vacuum cleaner hardly go out and stop working, and often one have to deal with other problems but the failure of the vacuum cleaner’s engine, as these wear out slowly in time. In order to repair the engine, you do not have to worry about taking a lot of expertise or high tech equipment but in fact, you’ll need your hands and common sense.
When disassembling your vacuum cleaner, start by getting rid of filters, removing the handles, take out the switch assembly being careful not to disturb the electrical connector, which stays underneath.

Remember to keep all the items away from water. And also keep the equipment out of children’s reach due to dangerous factors.
One more thing is that you can arrange them in a particular order, so you better remember where each should go. In any case, the end result after this first phase should look like this:
Dealing with the motor
Looking at the end of the motor, there is a metal shield you should lightly tap off to expose the blower fan, then remove the nut that is holding the blower fan in its position. Next, you can gently lift out the carbon motor brushes, the producers hold them in place with spade connectors so you can smoothly pull them out directly. These motor brushes should look long and solid and if so, should typically last a very long time. Now you need to remove the brush, then you ought to clean them with an electrical cleaner (or replace them completely) to get the best out of your best upright vacuum cleaner in the future.
If you decide to replace those brushes, always replace both at the same time. After you take care of them very carefully, you can remove the vacuum engines stator. Finishing this by pressing down on the metal spring clip that fastens it in place and the stator should easily slide out.
You may have noticed that the commutator which can be found on the end of the rotor, where those rings of copper strip the brushes by rubbing against them. This piece may get dirt and scored, which is a major problem with the faulty vacuum cleaner engines. These places are some of the most causes that we have noticed from previous users because they pay less attention to these kinds of inside engine. Here is what it looks like:
Some in-depth problems
The commutator does not have to be perfectly smooth and will still operate fine if there are a few small scores present around it, so use feather-like strokes to sand down the commutator and beware not to sand a lot away. The deep scoring is the point where the ends of the brushes contact the commutator, so the heads of the brush should contact tightly with the smooth copper most of the time. Using wet and dry fine sandpaper, fold it into a lengthy strip, enough to carefully sand down the end of the rotors commutator.
