How to Fix a Vacuum Cleaner with No Suction

Does your vacuum not suck? ???? This article’s going to show you how to fix a vacuum cleaner with no suction that does not suck or has lost suction. We’ll also discuss some causes for why a vacuum loses suction and more.

How to Fix a Vacuum Cleaner with No Suction

  • Make sure the chambers or bags are empty.
  • Having your vacuum’s height setting too high will make it impossible to vacuum all the dirt and debris from the floor. Tile or wood should be bare floor with the elevation adjusted upward. With a hardwood floor you won’t get much benefit from setting your carpet deep.
  • It probably won’t be able to do too much sucking if its air or exhaust filter is clogged. Your air/exhaust filter should be cleaned or replaced. There you have it!
  • In the event of a clogged vacuum cleaner hose the vacuum cleaner will be unable to do its essential job. Remove anything obstructing the hose of your vacuum if you think it is. Try straightening out the paper and shining a flashlight through one end. Otherwise try dislodging the obstruction with a blunt object just to make sure your hose isn’t damaged.
  • Is your brush roll spinning? You might just have too much hair if it isn’t. It’s inevitable for anyone with pets or children and a long-haired spouse to deal with this issue. There is a simple way to clean your brush roll included in our vacuum hacks compiled earlier.
  • It sounds as if there is a belt issue even though the brush roll is clean. Don’t worry about it. There are always instances of this. We see this issue with vacuum cleaners the most often. It isn’t that complicated to replace a belt and it isn’t that expensive either.

What Causes a Vacuum to Lose Its Suction?

As the electric motor pulls vacuum cleaner suction it pulls the dirt from the hose or chamber depositing it into a bag or cup. In addition to rotating brushes and beaters several vacuum cleaners have suction chambers that house rotating brushes or beaters to agitate dirt for removal. 

All of these items must be free of obstructions and functioning properly for a vacuum cleaner to be 100 percent effective. This will result in gradual vacuum suction loss.

Vacuum’s Height May Be Wrong

If the height setting on your vacuum is too high as compared to the type of floor you are vacuuming this is the first and most basic reason why it won’t pick up things from the floor. In a vacuum there is usually a knob or a lever to adjust the vacuum. There may be a sign that says “Bare floor” followed by 1 to 5 numbers. The bare floor setting of your vacuum will allow the vacuum to seal to the hard floor to allow maximum suction power so it is recommended for tiles wood and other hard floors. Your carpet should be lower than the level of the bare floor on your dial or lever. Check if the problem is fixed by lowering your vacuum to the lowest setting first.

Vacuum’s Bag May Be Full

A full vacuum bag or collection canister may be the cause of your vacuum’s loss of suction if it refuses to pick up on a lower setting. As a result you can easily determine which of these is causing your vacuum to perform poorly. Bagless vacuums and upright and canister vacuums both have a fill line on the front. There is no more room for dirt and hair to collect if they are above the fill line at either collection spot. There will be no suction power in the vacuum so nothing can be picked up on your floor. Sometimes the collection canister needs to be emptied or the vacuum bag changed to solve the suction problem.

Vacuum’s Hose May Be Clogged

A clogged hose leading to the canister or bag may have occurred if an overfilled vacuum bag or emptying the canister did not fix the problem. The hole where the bag or canister attaches to the vacuum might be clogged with hair if you remove the bag or canister. Try pulling out hair chunks with tweezers if you have them. Alternatively you can detach the vacuum hose and work on it that way if it doesn’t seem like you are getting it all.

To remove stubborn clogs in the middle of the hose you will need to use one of two methods I have found to remove the clog. To begin remove the hose completely take it outside and rotate the hose as fast as you can while tightly holding onto the end that is unclogged. 

It allows you to withdraw the blockage from the hose by pulling it out with centrifugal motion. I have also discovered that you can use a long stick such as a broom handle to clear a vacuum hose. Begin feeding the vacuum hose with care. You can push the clog out of the hose by pushing it through until it finally pops out. If you use any of these methods you will usually find a lot of loose dust that will spill out the moment the clog is removed.

Vacuum Probably Isn’t Airtight

A vacuum cleaner works by sucking up debris from the floor with the help of a vacuum. There will be no way to pull the stuff up if the air is leaving the system.

The next common reason your vacuum isn’t working well is when it isn’t airtight. If the vacuum isn’t full of dirt and the hoses aren’t clogged it could be because it isn’t airtight. As its name suggests a vacuum pulls dirt and scraps from the floor using a vacuum created by the machine. There is no way for the bag or canister to pull the stuff into it if the air is escaping. In spite of the fact that it may sound very technical errors that we frequently make are the most frequently responsible for this.

You should check the connection between the vacuum hose and the vacuum first. Your hose may not have been returned to the hole in the base tightly enough if you removed it to use the attachments. The vacuum will not pick up much dust from the floor when there is a gap for air to get past the closure. A secure connection should be made between the pieces. Make sure that your vacuum bag is tightly attached to the vacuum if that appears to be the case. During the installation of the vacuum bag you may not have pushed it on far enough which would cause it to fall off.

The only way to ensure the bag is airtight is to use a little duct tape on the folds.

Vacuum’s Roller May Be Clogged

Assuming everything appears to be fine with your bag and hoses the final step is to flip the vacuum over to see if the roller is damaged. Hair or yarn on the roller will prevent the roller from turning or brushing through your carpet and it will be very difficult to pick up dirt. You can easily fix the furry appearance of your carpet roller with a pair of sharp scissors if it appears clogged and furry. Begin by cutting the hair and gunking a bit at one end of the roller at a time. 

Cut it into small pieces so you can remove the furry mess and throw it away as you cut. If the vacuum is working better after the flip you should flip it back over.

The vacuum was functioning correctly before but if it is still not working at this point you may need to have it repaired. You can find out if your model and make are serviced at local shops by calling. While it is generally not very expensive to repair your vacuum you may want to buy a new vacuum if the problem is more severe. Before you drag it down to the shop the person answering the phone may be able to do a relatively quick diagnosis over the phone. You might be told to purchase a new vacuum instead of fixing your vacuum depending on the symptoms it is exhibiting.

Check Vacuum’s Air Filter

When the air travels through the vacuum cleaner it is captured by the air filter. Filters that are clogged will reduce the suction of the vacuum cleaner. Your vacuum owner’s manual will include instructions for cleaning a clogged filter.

Check Vacuum’s Exhaust Filter

As air passes through the vacuum cleaner particles are trapped in the exhaust filter. It is impossible for the vacuum cleaner to maintain proper suction if the filter is clogged. Your vacuum owner’s manual will include instructions for cleaning a clogged filter.

Check Vacuum’s Blower Wheel

Rotate the blower wheel using your hands. Make sure the wheel of the blower isn’t obstructed if it doesn’t turn freely. A blower motor problem rather than a blower wheel issue is likely if no obstruction is present.

Check Vacuum’s Motor

The suction will be lost if the motor is damaged. In addition to sounding out-of-key a bad motor may also smoke or run irregularly. Generally you cannot replace motors yourself. If the motor is bad you need to replace the vacuum. A rotating plastic fan blade however is used on some bag vacuums to create suction. Motor axles are directly connected to fan blades. In the bag dirt passes through the blades and is collected. 

The motor may run off-key or vibrate if any of the blades have been damaged causing the vacuum to lose suction. If the fan blade is damaged replace it.

Check Vacuum’s Belt

Vacuum cleaners often have problems with their belts malfunctioning or breaking. In most cases it’s not difficult to check a vacuum’s belt and to determine whether it is damaged though you should be sure to check whether doing so will void the warranty beforehand. In the event that the vacuum belt breaks take it to the supplier or a retailer for a replacement.

Still No Suction?

You can follow up with the manufacturer to learn which steps to take if you’ve followed all of the steps in this guide and your vacuum still isn’t working. A qualified vacuum repair person can generally fix the problem for a very reasonable price and he or she will know how to test for air leaks and other problems that can affect the vacuum’s suction.
