How to Fix a Vacuum Cleaner with No Suction – Identification and Resolving the Issue

There are a few vacuum manufacturers who claim that their product will never lose suction power and, therefore, never need to be fixed. They must be reading from a different manual than the one I’m looking at (ba-dum-truss) because almost every vacuum cleaner I’ve ever used has eventually lost suction power and needed to be fixed.

If your vacuum is having poor suction or has lost suction power completely, don’t despair. In this post, we’ve tailored everything you’ll need to know about your vacuum, identify the reason for the crisis and resolve it in a few easy steps. So, Let’s begin.

Check the Warranty of Your Vacuum Cleaner

Check the Warranty of Your Vacuum Cleaner

First things first, check the manufacturer’s warranty to see if your vacuum is still covered. If it is, then you can take it to an authorized repair center, and they will fix it for you. If your warranty has expired, or if you bought your vacuum second-hand and don’t know if it has a warranty, then you’ll have to fix it yourself, but don’t fret.

Check the Manual

Check the Vacuum Manual

Check the manual that came with your vacuum.

Oftentimes, the manufacturer will list common problems and their solutions in the manual. If you can’t find the answer to your problem in the manual, then it comes down to DIY.

Check Your Vacuum Settings

Check Your Vacuum Settings

If you’re having vacuum suction problems, it’s most likely because of your vacuum’s height setting. You may be using the wrong height setting for your carpet. The setting is too low, causing the vacuum to miss dirt, or maybe the setting is too high, making the vacuum difficult to push.


The best way to avoid these common vacuum cleaner problems is to set the height of your vacuum properly.

  • For carpet, hardwood floor, and tiles-based floor, the lowest setting is best. This allows the vacuum to get close to the ground and pick up all the dirt and dust.
  • If you have a thicker carpet, you may need to raise the height slightly. But in general, the lowest setting is all you need.

Tip: If you’re not sure what setting to use, just go with the lowest setting, also known as the bare floor setting.

Inspect the Vacuum Cleaner Floorhead

Inspect the Vacuum Cleaner Floorhead

The most common cause of lost suction power is a blockage somewhere in the machine. The first place to check for a blockage is the floorhead.

If it’s covered in dirt and debris, that could be blocking the airflow and causing suction loss.


To clean a vacuum’s forehead, start with,

  • Disassemble the floorhead from the vacuum cleaner.
  • Check for any blockages in the suction path. If there are any blockages in the suction path, clear them.
  • To do this, gently push objects such as hair or dirt backward through the suction hole until they are dislodged. Use a soft brush to dislodge any build-up.
  • Once the blockage has been cleared, replace the floorhead and test the vacuum cleaner for suction.
  • Reattach the floorhead to the vacuum cleaner.

If the floorhead has suction, then the problem is with either the hose or filter.

Inspect the Intake Port

Inspect vacuum Cleaner Intake port

The second thing you should check is the intake port. The intake port is located at the bottom of the vacuum, where the dirt and debris are sucked into the machine. If this area is clogged, it will cause a decrease in suction power.


To clean the intake port, simply remove any debris that may be blocking it. You can also use a small brush to remove any build-up of dirt and dust.

If the intake port is clear and you are still experiencing suction loss, the next step is to check the vacuum’s filters.

Check the Hose Pipe

damaged vacuum hose

Cracked or damaged hoses are one of the most common reasons for a vacuum to lose suction power. If you suspect that your hose tube is damaged or broken, it’s important to check it for cracks or other signs of wear and tear.

To do this, start by disconnecting the hose from the vacuum cleaner. Then, inspect the hose carefully, looking for any cracks, holes, or other damage. If you find any damage, it’s best to replace the hose rather than try to repair it. But don’t worry, we got you if you want clean the hose anyway.


  • Start by detaching the hose from the vacuum.
  • Take a broom handle, put it inside, and keep going until you reach the other end of the hose pipe. This way, you can unclog the hose tube.
  • Move forward to the sink and run water through the hose, you may use homemade solutions or detergent to get an even better result.
  • Let it air dry for a few hours and re-attach it to the vacuum.

If suction is restored, then your vacuum hose was likely the culprit. Regularly checking your hose pipe for damage can help ensure that your vacuum always has strong suction power.

Check the Canister or the Dust Bag

Check the vacuum canister

Most vacuum cleaners have a dust bag or dust container that needs to be emptied when it gets full. Depending on the model, these can be small or large capacities. There are also bagless vacuums, which have a dust container of small capacities that can be easily removed and emptied. Others have a vacuum bag that needs to be replaced when it gets full.

If the bag is allowed to fill up completely, it will reduce the vacuum cleaner’s suction power and cause it to work less effectively. Additionally, air will leak out of holes in these bagged vacuums, making them less efficient at capturing dust and dirt.


  • First, never let it cross the fill line, empty before it’s full.
  • Use a dirt sheet around the bag to protect the bag from wear and tear. (Avoid Glass suction)
  • Keep it safe from wet things, place your vacuum in a dry place when not using.

Regardless of the model, it’s important to check the canister or dust bag regularly and empty it when necessary. And we encourage you to follow the instruction provided on how to empty the vacuum cleaner for a better understanding.

Inspect Your Vacuum Filter

Inspect Your Vacuum Filter

The vacuum cleaner’s filters are an important part of preventing suction loss. There are two filters in vacuum cleaners, the exhaust filter and the motor filter. The exhaust filter is located between the vacuum cleaner’s main body and the dustbin. It prevents dust and dirt from being recirculated back into the vacuumed area.

The motor filter is located inside the vacuum cleaner’s motor housing. It protects the motor from dirt and debris.

Check both filters for grime build-up; if the filter fails, then the vacuum fails.


  • If your vacuum has a washable filter, it should be washed in cool water with a mild detergent every three months or as needed.
  • If your vacuum has a two-filter system, it is recommended that you replace one of the filters every six months.

Check the Rotating Brush or Roller

Check the Rotating Brush or Roller

The brush roll of a vacuum cleaner is also known as the brush bar. It is the part of the cleaner that has the bristles that rotate and move back and forth. The vacuum’s brush roll is located at the bottom of the cleaner and is usually made of plastic or metal. The big difference between a brush and a roller is that a roller has bristles that rotate.

This action helps to loosen dirt and hair so that it can be vacuumed up more easily. If your brush roll is clogged with hair, it will not rotate correctly and fail to clean, and as a result, you get suction loss.


To clean a clogged brush roll,

  • Start by cutting any hair or debris from the bristles with a scissor.
  • Then, use a long stick to reach down into the crevice where the brush bar is located.
  • Gently pull out any small pieces of dirt or hair that are caught in the bar by hand.
  • Use a brush (toothbrush) to clean out the remaining dirt.
  • Rinse off the brush bar with water to remove any lingering dirt or hair.

If you regularly clean your brush roll, it will help your vacuum cleaner to work more effectively and last longer.

Inspect the Vacuum Cleaner Belt

Inspect the Vacuum Cleaner Belt

Many vacuums have a belt that helps to power the brush roll. Over time, this belt can become worn, which can cause suction loss. As a result, it’s important to inspect the vacuum belt regularly and replace it as needed.


To do this,

  • First, unplug the vacuum cleaner and then remove the entire bottom plate.
  • Next, locate the vacuum belt and inspect it for wear. If the belt is damaged, it will need to be replaced.

Once you have replaced the vacuum belt, reassemble the vacuum cleaner and test it to make sure that suction has been restored.

Seek Professional Help

Vacuum repair shops can diagnose the problem, and often they can fix it without having to replace the entire machine. So, if you’re having trouble with your vacuum, don’t despair- just take it to a vacuum repair shop and let the professionals take care of it; chances are you won’t have to buy a new vacuum cleaner.
