Vacuum cleaners, commonly known as vacuums, are ubiquitous in modern households. They make your life easier by quickly cleaning up dirt and dust in carpets and hard surfaces such as tile or wood floors. But occasionally, you may discover that your vacuum cleaner has lost suction power while attempting to clean a room. This can be an annoying issue that requires the necessary attention if you want to restore its performance back to its original level. In this blog post, we will look at some possible reasons why vacuum cleaners lose suction along with their fixes so that you can get your trusty appliance running again smoothly. So read on for all the details on how to fix a vacuum cleaner!

How Vacuum Cleaner Works

Vacuum cleaners are one of the most common cleaning tools. Modern vacuums use an electric motor to draw in air and suck up dust, dirt, and debris from your carpets or other surfaces. Most vacuum cleaners come with a variety of attachments for different uses, including a crevice tool, dusting brush, upholstery nozzle, extended hose attachment, and more. These attachments help to maximize the vacuum cleaner’s performance on different surfaces like hardwood floors or furniture.

As you operate the vacuum cleaner across a surface, it will pull in all sorts of small particles from carpet fibers as well as larger chunks like pet hair or pieces of food. It also contains powerful suction, which will pick up dirt that has been embedded deep into carpets over time. The suction created by the vacuum is generated through its fan-like turbine blades spinning at high speed within its power head, which rotates brushes to further dislodge dirt from fibers.

To capture all those allergens and debris that have been lifted off by your flooring during operation, most vacuum cleaners contain filtration systems such as microfiber PET bags along with synthetic fabric bags located within their main intake tube so they can trap finer particles before they disperse back into the environment once again; thus improving indoor air quality while ensuring quick disposal (via removing bag) once full after each usage session making them convenient for maintenance work too!

Reasons Why Your Vacuum Cleaner has No Suction Power

Check the Rotating Brush

The rotating brush and vacuum belt are an important part of the vacuum cleaning system and can be a common source of lost suction, especially for an upright vacuum cleaner. Over time, hair and other debris can accumulate on the brushes, reducing their effectiveness. It’s important to regularly check for tangled-up hairs or pet fur that might get stuck in the roller brush itself or around its base. If you find any kind of blockage, it should be removed carefully to ensure that the power isn’t drained from your vacuum cleaner.

In addition to checking for blocked bristles on the brush head, some modern vacuums have specialized LED lights alerting users when there’s something clogging them—like carpet fibers or strings caught underneath rotating brushes—so make sure this feature is turned on if it’s available on your machine.

It’s also recommended to periodically inspect your roller brush for signs of wear-and-tear like broken plastic housing pieces, as these could lead to decreased productivity due to restricted rotations as well as contact with sharp surfaces inside its chamber, which may penetrate through thinning fabric bags leading them prone punctures and leaks over time. Check whether all bristles are intact and not worn out; replace any broken parts immediately with genuine spare parts approved by the manufacturer before using them again.

The Motor

Usually, when a vacuum cleaner has lost its suction power, it is due to an issue with the motor. Motors are essential components that use electricity to generate motion and can be found in various domestic appliances. In order for your vacuum cleaner to maintain powerful cleaning performance over time, regular checks on the motor are necessary. This can easily be done by checking if there is any buildup of dust particles or dirt accumulating around the exterior of the motor housing. If so, these should be cleaned out using a dry cloth, and careful attention should be paid as this could damage electrical components underneath or prevent airflow from reaching them properly.

Though rare, if after completing all previous steps you still don’t get top results, then you may have an issue with overheating caused by the motor itself. To avoid this happening again, it’s best practice to take regular preventive maintenance measures such as periodically lubricating moving parts inside and outside the machine’s body and always allowing at least 10 minutes of cooling off before the next usage session following long periods operating at full power mode/settings which will optimize its performance too!

Clean the Filters

Maintaining clean filters is essential to maintain the suction of your vacuum cleaner. Without regular cleaning and replacement, dirt, debris, and pet fur can clog up the filter reducing suction over time. Depending on the type of vacuum cleaner you have (e.g., bagged or bagless), different methods will be used for cleaning and/or replacing filters.

Bagged vacuums typically utilize a post-motor filter that requires washing with soap or harsh chemicals every two months to ensure optimal performance. If not washed regularly, a vacuum cleaner’s filters can become severely clogged, leading to reduced suction power which affects how well your vacuum performs an overall task like picking up large objects such as chunks of cereal or pet hair from carpets or hardwood floors.

For bagless vacuums, there are three main types of filters: pre-motor foam filter, pre-motor felt filter, and post-motor HEPA filter – all aimed at removing tiny particles from sucked-up air before it gets expelled out again into the environment (this helps improve indoor air quality). To maintain peak performance, all three should be checked frequently for dust buildups, then either wash them in warm soapy water if possible – otherwise, replace along with any disposable paper bags *if applicable) every three months – 6 months, depending on use frequency.

Obstructions in the Vacuum Airflow

In some cases, the reason why a vacuum cleaner might have lost suction is due to an obstruction in the airflow on the vacuum hose. This could be anything from dust and debris that has built up inside the hose or tube of your vacuum cleaner to blocked seals or filters elsewhere on the machine. When this happens, it can severely reduce the amount of suction power generated by your vacuum, making it increasingly difficult for you to clean effectively. To avoid this issue, there are several steps you can take; regular cleaning of all parts of your vacuum with a dry cloth will help ensure any buildup does not block up pipes and hoses. Additionally, if your vacuum dust collector bag is full or damaged, then emptying it out every once in a while should help stop blockages from occurring as well as encourage better overall suction power when using your vacuum cleaner.

Check for cracked or damaged hoses:

Cracked or damaged hoses can be one of the main factors causing your vacuum cleaner to lose suction. Over time, the plastic on a hose can become brittle and crack due to wear and tear from being dragged around during use. Examine all areas of the hose carefully for any visible breaks or tears on its surface. If there are any signs of damage, it’s best to replace the hose immediately, as this is likely causing a blockage in its airflow, which will result in decreased suction power. Additionally, check that the other connections on either side of the hose are secure and intact, with no obstructions blocking them from providing adequate airflow.

Regularly replace the bag or empty the dust container.

Regularly replacing your vacuum bag or emptying the dust container is an essential maintenance habit that will help with the suction of your vacuum. Depending on the type of vacuum you have, it may come equipped with a disposable bag to collect dirt and debris or a cup-style dust container. Both should be emptied regularly in order to prevent clogging and maintain optimal suction power.

If you are using a disposable paper bag, make sure to replace it often before it gets too full. For some models, such as canister vacuums, this means changing the paper bags when they’re about one-third full; for upright vacuums, sewing machines, or anything else that comes equipped with reusable cloth dust bags, change those when two-thirds full. It’s also recommended that you frequently check the condition of the filter so as not to impede airflow and reduce suction power due to blockages from clogged filters.

The other popular option used today is airtight plastic cups mounted directly onto motorized hoses which must simply be emptied out whenever necessary after use (usually once per week). This low-maintenance solution requires minimal effort but still functions effectively since dirt goes straight into traps built into its walls – either way, it helps keep things nice and tidy, especially if used in high-traffic areas like pet hair pickup!


Vacuum cleaners are an essential part of any home and although they can seem intimidating to fix when something goes wrong, diagnosing the issue isn’t too difficult. When a vacuum cleaner loses suction, it could be due to anything from a clogged filter or dust container to an obstructed hose or broken motor. The good news is that these issues are usually easy enough to diagnose and repair yourself; however, if you’re still unsure, you may need professional help. Regardless, with a quick check of your filters and hoses, as well as ensuring all components are clean and in working order, your beloved vacuum will soon be back up on its feet and doing its job!
