10 Steps to Repair Your Car Vacuum Cleaner at Home

Car vacuums are indispensable appliances for all drivers because they help them save time and effort in cleaning their cars. However, after a long time period of use, your car vacuum cleaner suddenly decreases its suction power or even stop working. Do you know how to handle? The following article is all you need to fix these problems.

Step 1: Check your car vacuum to determine where the breakdown come from. Maybe because the machine had not been turned on? Suction force is weak or irregular? Hose is entangled fluff or debris? Breaker is isconnected? During the operation, does it have any strange smell or noise?Step-1

Step 2: Verify that your vacuum cleaner has been powered on. You should use a mini multimeter to test the electrical circuits. But if you don’t have any instrument like that, a bulb or a radio can be used as the alternatives. Remember that no electricity means no operation from your vacuum cleaner.

Step 3: Check that the machine to make sure it does not overheat. Some car vacuums have the auto-disconnect mode when the machine is overheated. In this case, you should unplug the power and wait from 20 to 30 minutes until the engine gets cool. Finally, don’t forget to check for obstructions or other problems before rebooting the machine.

Step 4: Check the lubrication of the shaft, the axle-bearing of the motor and the abrasion of the electric brush because poor lubrication and abrasion can reduce the cleaner’s suction power. In addition, the full-dust bag can fill the airways and reduces the suction power so you should check the dust bag to see whether it is full of dust or ragged. Besides, the straw entangled with hair, fur, or shredded paper can be another reason reducing the suction power.

– Replace the dust bag if it’s too dirty and clean all of the filters.

– Replace the belt: Ensure that the belt is present in the brush roll, axle or any other moving parts. A belt slipping from the shaft can make the rubber heats up and creates unpleasant odors.

– Clean the brush roll and make sure it still works well. Lubricate the bearings, if necessary, replace the bearings and the brush roll.

Step 5: Check the electrical path by an Avometer. Check whether the power cord is frayed, peeling, cut to tape or replace the new wire.

Step 6: Check the engine to see whether it operates well or not. It’s a waste if you replace the entire engine (possibly more expensive than buying a new vacuum cleaner). Just replace some key parts if they are damaged.

Step 8: Replace the bearings or lubricate them. There are bearings for the motor and the blower, there are also bearings for the drive shaft and the wheels.

Step 9: Check the fan to see whether it is bent or broken. If you find out, you should replace it immediately. Fans usually attached directly to the engine. Any imbalance among the parts can damage the motor or the bearings.

Step 10: Replace any broken wheel. It is not a too big problem, but if the wheel fails, it can make a vacuum cleaner operate slower.

Above are the 10 steps for fixing a car vacuum cleaner. You can repair your machine by yourself at home, don’t forget to read the instruction manual from the manufacturer before starting to fix. However, if you are not aware of the structure and operation of the vacuum cleaner, it’s best to bring it to the store so that they can repair it safely and quickly.

Tips

  • Read the manual instruction from the manufacturer is absolutely essential. From the manual, you can find a variety of information from minor, general instructions to important details. Make sure you read it carefully to know how much voltage the machine use, how much suction power it produces, …
  • During operation, if your machine suddenly changes its sound. For example, it’s much louder or the appearace of a rattle. Then you should stop it immediately and try to find what going wrong. Remember that the damages can get worse it you continue to run your machine.
  • Listen to your machine and try to figure where the noise comes from so that you can guess the location of damage. In particular, noise can come from bent fan blades, wear-out ball bearings or sleeve bearings.
  • Periodically maintaining your machine is a must-do task to prevent unexpected repairs.
  • In the first time you use your machine, take a look the whole machine and the accessories. Some parts to look include:
  • A motor located at the machine’s center. It uses a centrifugal fan to drive. Its function is to blow out the air, which produces an internal partial vacuum that sucks off all the dust and soil from your car’s interior into a dust bag. This motor also has a brush roll (also called as an agitator)
  • Before connecting to the power source, the cord must through a fuse. This fuse help to disconnect the power supply when the machine overheats or when any trouble happens.
  • Just replace the motor if it cannot work anymore. A new motor is usually costly, you may pay an amount of money nearly as large as a new vacuum cleaner.
  • Avoid sucking off solid objects such as a screw, a coin or a pebble. These objects can obstruct the blower of your machine, which reduces the suction power and even causes some problem on your machine in a long term.
