1. Shark Vacuum Won’t Turn On

When your Shark vacuum doesn’t power on, there could be a minor problem that you can fix yourself. Explore the below possible causes and fixes for a Shark vacuum that won’t power on.

  • If your power cord is not plugged in the socket, or you don’t have power in the mains, your vacuum won’t power on. Make sure you have plugged in the cord and switched on the socket.
  • If you have a handheld/cordless vacuum, it could be that your battery is not charged, so charge the battery and try to power it on.
  • A burnt fuse can also cause this problem, so make sure to check it out and replace it if necessary.
  • The circuit breaker could also have been triggered, so it has to be reset for the vacuum to power on.
  • It could also be that your vacuum is dead, so you might have to send it for repairs or buy another unit.

2. Shark Vacuum Stopped Working

There are cases when your Shark vacuum will just stop working. Several issues could cause the problem. Below are the common reasons that can cause a Shark vacuum to stop working, plus the possible fixes.


  • Check the socket, it might not be plugged in well, or it came off the socket while you were vacuuming
  • It could also be that the fuse has blown, so you will have to replace them.
  • The thermostat might have powered it off because of overheating. Wait for an hour or so and try to power it on.
  • The circuit breaker might have gone off cutting power, so it needs to be reset.
  • Though unlikely, your vacuum might be dead altogether. Send it for repairs, or it’s time to replace it.

3. Shark Vacuum Overheating

One of the common problems that almost all Shark vacuums encounter is overheating. Several reasons can cause overheating.

  • The first culprit, though rarely, is electrical faults or a faulty motor. Check for frayed cables and replace them if necessary.
  • It could also be a clogged filter restricting airflow. Unclog the filters to ensure the vacuum is sucking dirt well.
  • Also, check the dust cup as it could have tiny dirt particles blocking airflow. Unclogging the dust cup should solve the problem.
  • Another possible cause for overheating is a jammed brushroll. Check it out and remove any dirt or hair tangles that cause jamming.

4. Shark Vacuum Producing Unusual Noise

When your Shark vacuum is louder or starts producing inconsistent noise, it is a sign that it is overwhelmed. Below are some of the causes and possible ways to fix them.

  • The first culprit is a dirty filter that needs to be cleaned to allow for unrestricted airflow.
  • A dirty or jammed or dirty brushroll could also be the reason your vacuum is louder, so clean it.
  • Another reason could be a malfunctioning motor. Switch the vacuum off, wait for it to cool down, and check whether it’s still producing funny noise.

5. Shark Vacuum Lost Suction

Nothing sucks like a vacuum when it’s not sucking anything and leaves dirt and debris behind. Lost suction can be a minor problem or a major one. Below are some of the causes and fixes for low suction.

  • To start, you could be on a low suction level, so make the necessary adjustments if your Shark vacuum has adjustable suction levels.
  • The next culprit could be a full dust cup which means there is no space for dirt to be sucked into. The solution here is to empty the dust cup.
  • Also, check the filters to ensure they are not clogged as they may restrict airflow when clogged and cause suction loss.
  • A blockage in the vacuum could also cause no suction in Shark vacuum, so make sure to detach the dust cup, intake opening, and hoses to ensure there is no debris blocking suction.
  • Loose hose connections or broken hoses can also cause suction leaks and consequently low suction. Make sure they are correctly fixed and are in good working condition.
  • If none of the above tips work for you, probably the motor is bad. In this case, you have to replace the motor or buy a new vacuum.

The above are some general problems you will face when using a Shark vacuum, plus their fixes. Below, we have also explored the problems that are specific to some Shark models.
