How To Repair Car Vacuum Cleaner

If you find that the vacuum cleaner is completely unresponsive, first look at the fuse in the cigarette lighter plug, or check the lithium battery charge of the wireless model. Under normal circumstances, a tight power cord can solve half of the problem. If the suction is obviously weakened, the “culprit” is basically a clogged HEPA filter, or something stuck in a hose or suction nozzle. At this time, all you need to do is disassemble the dust bucket, wash the filter screen (remember, be sure to dry it thoroughly before loading it back), and clean up the sundries inside. The most important thing to be vigilant is to smell the paste or hear the harsh noise. In this case, the power must be cut off immediately, and the housing must be disassembled to see if the motor is surrounded by hair or foreign matter has entered. It usually only takes a screwdriver and a can of compressed air to repair this thing, which can be done in 10 minutes, which is much cheaper than replacing it with a new one.

Step 1: Eliminate Power Supply Failure

Car vacuum cleaner does not start, the most common reason is that the circuit is broken. Depending on whether you are using wired or wireless models, the focus of the inspection is different.

Check the 12V cigarette lighter plug

For wired models, the cigarette lighter plug is the most vulnerable place. You can unscrew the top of the plug and check the glass tube fuse inside. If the filament in the middle is broken, a fuse of the same specification can be revived with blood. In addition, sometimes the cigarette lighter socket in your car is too dirty, and soot or dust has accumulated, resulting in poor contact. Cleaning it up may have a wonderful effect.

Check the battery condition of the wireless model

If you are using a handheld wireless model, you should pay attention to the health of lithium batteries. If the vacuum cleaner is powered off immediately it is started, it is very likely that the battery cannot store electricity or the charging port is loose. When plugging in the charger, be sure to confirm that the charging indicator is really on.

Step 2: Restore Suction And Airflow

The motor is spinning but can’t suck dirt? That means there is resistance inside the machine and the airflow is blocked.

Clean the HEPA filter screen and dust bucket

Once the HEPA filter is stuck to death by dust, the airflow cannot enter, which is the “life gate” of suction “. Disassemble the dust bucket and take out the filter screen. If it is a washable model, use cold water until the water flow becomes clear. Here I have to point out: the filter must be 100 percent dried (usually 24 hours) before it can be put back in. If you can’t wait, the filter with water will not only mold, but also suck the water directly into the motor, and then it will really be scrapped.

Remove obstructions from hoses and nozzles

Take a flashlight and shine it in your hose or flat suction mouth. Pebbles, coins or pet hairballs are most likely to get stuck in the turning area. Poke it with a blunt stick, or blow it with compressed air, and it usually spits out the dirt.

Step 3: Deal With Motor Noise And Odor

When the vacuum cleaner screams or emits a burnt smell, the motor is in a “struggling” state of high load.

Check the inside of the motor housing

At this time, unplug the power immediately, or the motor will burn out in minutes. Unscrew the housing with a screwdriver and go straight to the motor. Carefully observe the vicinity of the motor shaft to see if there is any hair, thread, or fine debris that penetrates the filter screen.

Internal cleaning with compressed air

Excessive dust accumulation in the motor case will lead to poor heat dissipation. I used to use compressed air against the motor vent a burst of fierce spray, the dust inside the clean. After reducing friction and heat dissipation resistance, the motor will rotate more smoothly, and the harsh noise will naturally disappear.
