Vacuum cleaners are a technique that, as a rule, no one really thinks about until it starts to junk. Fortunately, vacuum cleaners are fairly simple machines and are often easy to repair yourself. Read this article first, then start repairing.

Steps

1. 1 Examine the vacuum cleaner and find out what is wrong with it. Does it not turn on? Runs for a short time and then turns off? Vacuuming weakly or unevenly? Leaves behind dust or other debris? Disconnects the circuit breaker? Does it make noise or odor during operation?
2. 2 Check that your vacuum cleaner is plugged in and turned on and that there is power in the electrical outlet. If you don't have an electrical network tester, try plugging in a working lamp or radio. Of course, this is obvious, but without an electric current, your vacuum cleaner will not be able to work.
3. 3 Check overtemperature shutdown mechanism. Some vacuum cleaners are equipped with a device that turns off the motor if it overheats. If your vacuum cleaner is cut down, unplug it, read the instructions and wait for a while (20 or 30 minutes). Then check it for clogging and gently turn it back on.
   • Note that some vacuum cleaners have a small inline fuse that is almost completely hidden between the switch lead and the motor coil. It is not easy to spot and is wrapped in duct tape. The most common type of such a fuse is SEFuse SF109e, which can be bought on the Internet for $ 1-2 (not more than a hundred rubles, but, however, not a fact).
4. 4 Make sure you take the utmost care of your vacuum cleaner. If the machine works, but pulls weakly, or there is debris behind the vacuum cleaner, or you smell dust or burning, then:
   • Replace bag and clean all filters.
   • Make sure the air ducts are clear. Use a squeegee handle or a bent hanger to clear any blockages in the hose. Be careful not to push the blockage deeper with your hanger.
   • A belt connects the carrier shaft and the brush roller. Replace belt (s). Make sure the belts are wrapped around the brush roller, carrier shaft and other moving parts such as mechanically driven rollers. A slipped belt can cause a characteristic smell of hot rubber and / or plastic.
   • Clean the brush roller and make sure it rotates freely. Lubricate the bearings. The brush rollers can be wooden, especially in older models, or made of plastic, in the case of more modern vacuum cleaners.
5. 5 Make sure the brush roller spins when it should. This can be done by turning the vacuum cleaner over and looking carefully under it. Do not touch the rotating brush roller and make sure there is no clothing, hair, etc. in the vicinity.
   • Some vacuum cleaners have a support roller or switch that releases the brush roller when it is turned on or switched to hard floor mode. Make sure the switch is set to carpets and that the support roller is activated when the switch is off.
6. 6 Monitor the electrical circuit, especially if the vacuum cleaner does not turn on at all. Use a multimeter to test for continuity. You're looking for open circuits:
   • From the socket to the switch.
   • Check the continuity of the circuit at the switch. On the breaker when closed (in the "on" position).
   • Two types of fuses used in vacuum cleaners.On fuses or breakers built into the vacuum cleaner.
   • From the switch to the motor.
   • In the opposite direction from the motor to the outlet. Remember that electricity must flow throughout the entire circuit.
   • This wire on the hose in the container vacuum powers the brush mechanism. All electrical circuits on the hose.
   • At the section where the wire and the vacuum cleaner are connected, there is a spring rewinding device. As it moves, breakdowns can occur here.
7. 7 Find the reasons why a fuse you replaced or a reset breaker knocks out all the time. Is there a short circuit somewhere? Does the motor turn off? Fix any problems you find.
8. 8 Check motor operation. Replacing the entire motor can be tricky (it can cost almost as much as a new vacuum cleaner), but you may be able to replace some of its parts.
9. 9 Examine the brushes. If they are worn out, replace them.
   • Open the case with brushes. Open the case with brushes.
   • Motor brushes. Remove and replace the brushes, remembering to connect the wires. Close the cover on the brush body.
10. 10 Replace bearings or apply fresh grease. These are the motor and fan bearings (which are often interconnected). The vacuum cleaner can also have bearings for the main shaft and any gears of the mechanical drive. Look where something is spinning (or should be spinning)
    • Before removing the motor or fan, pay attention to the drive shaft side play. If this is the case, then there is a high probability that the bearings have fallen off.
11. 11 Examine the fan for bent or broken blades. If you find it, replace it. The fan is usually attached directly to the motor. Any unevenness can cause imbalance, which in turn can damage the motor or bearings.
    • This is where you are can you collide with left-hand threads, depending on the design of the vacuum cleaner.
12. 12 Replace broken wheels. Changing wheels is not the most important repair, however broken wheels will undoubtedly slow you down. Shown here are wheels on two different vacuum cleaners. You may need to remove the plugs and caps to reach the attachment points.

14. 14 Fix all leaks. If something has punctured the hose, remove it with pliers and cover the hole with electrical tape. A good alternative is silicone sealant.

Tips

• Go to stores that sell office supplies, cleaning equipment, or vacuum cleaners. They should sell magnetic rods that fit in front of the nozzle, designed to pick up metal objects like paper clips and staples before they get into the vacuum cleaner. If you install such a tape, sometimes collect trash from it.
• Listen to your vacuum cleaner and see if it is making unusual noises. Try to find out what causes them. Franklin Peterson advises: "A guideline for detecting sources of unusual sounds is as follows. Bent blades cause significant vibration as well as noise. Worn bearings typically rattle and make sudden, harsh noises mixed in with general noise. Bushings clang constantly when worn." Worn bearings can also generate a high-pitched howl.
• If the sound of the vacuum cleaner suddenly changes (becomes louder or, for example, bounce), immediately turn off the vacuum cleaner and try to find out what happened. Running a vacuum cleaner with an emerging problem can quickly lead to new damage.
• When you open the vacuum cleaner for the first time, examine its insides to see how it works. There are different configurations of vacuum cleaners, but the main provisions are as follows:
  • In the center of the vacuum cleaner is a motor that drives a centrifugal fan. This fan pushes air into the hole and creates an incomplete vacuum in the machine. The resulting suction pressure carries dirt and debris from the carpet into a bag or container.
  • Usually a motor drives a brush roller, also known as a beater. It is a cylindrical brush that rotates in contact with the carpet to pick up adhering dirt.
  • The electrical wiring supplies current through the switch and fuse to the motor.
• Remove any dust and debris you find. A tuft of hair or a plug of dust can cause a problem on its own or cause other parts to overheat. Clean, pull out, or wipe off the dirt, being careful not to push it in.
• Try to avoid getting objects such as stones and coins into the vacuum cleaner. In many vacuum cleaners, air saturated with dirt enters the bag directly through the fan. Such objects become projectiles that damage the fan.
• Motors are expensive, so consider carefully if you want to replace a broken one. It might cost you as much as a new vacuum cleaner.
• Regular maintenance can prevent the need for repairs.

Warnings

• Unplug the vacuum cleaner before inspecting it, especially before touching the brush roller or touching internal parts and wires. A vacuum cleaner that suddenly turns on while you are working with it can injure you.
• Remove the spring rewinder very carefully. The spring may fly off. As you open the spring, relax it as much as possible and point it away from your face.
• Observe electrical safety precautions. If you are unsure how to fix electrical appliances, take your vacuum cleaner to a professional repair shop.
