Why do vacuum cleaners lose suction? There are several possibilities.


If your vacuum isn’t working as well as it used to, go through this useful checklist before investing in a new model:

Check the vacuum cleaner bag:

Vacuum cleaner bags collect all the dust and dirt collecting for bagged vacuum cleaners These bags are intended to allow air to pass through while trapping dust and allergies within.

The biggest disadvantage of utilizing bagged vacuums is that you must constantly replace the bags as they get clogged with dirt and dust. While it may sound more economical to just empty the dust out of a vacuum cleaner bag and re-use it, this can lead to a loss of vacuum suction (plus, it’s pretty messy work).

Over time and extended use, a very fine layer of particles will start to line the inside of a vacuum bag, remaining in place even after the bag is emptied. This implies that the bag will lose the necessary airflow to allow the entering air to escape. Suction decreases when the airflow is constrained. So check, change, and replace the vacuum cleaner bag often.

Check for a plugged hose:

Suction loss may occasionally be caused by clogged vacuum hoses. Hoses can get clogged with hair, dust bunnies, string, or anything else that can’t pass through the other end of the hose.

The airways inside the machine should also be examined. Examine any air passages you come across. If everything is clear, go on to the next item.

Check the vacuum cleaner’s filter:

Vacuum filters are similar to vacuum cleaner bags, except they are designed for specific purposes. bagless vacuum cleaners .

While some bagless vacuums (notably Dysons ) use centrifugal force to filter out particles, many bagless vacuum cleaners rely on a filter that acts as a sieve to purify the air coming out of the cleaner. Examine the filter to check whether it is blocked with dust or if it needs to be replaced.

Check for cracked or damaged hoses:

If you’re still losing vacuum suction, inspect your complete machine for cracked or broken hoses, since air escaping via a little crack may have a significant impact on your machine’s effectiveness.

If you discover a fractured hose, contact the merchant or manufacturer to see whether the hose can be replaced cheaply.

What if the problem with my vacuum cleaner is not with the suction?

A vacuum cleaner might also fail in the following ways:

  • A damaged or malfunctioning belt is one of the most prevalent vacuum cleaner issues. It’s usually relatively simple to open up a vacuum to check the condition of its belt, though you may want to check whether this will void the warranty before you start tinkering. If the vacuum belt is actually damaged, take it apart and return it to the maker or an authorized reseller for a replacement.
  • Another common source of vacuum problems is the agitator brush, which touches the floor and helps pick up the debris. Hair and thread may get entangled in the brush and prevent the brush head from rotating. Cleaning the brushes on a regular basis can assist to prevent this issue.
  • On top of general wear and tear over time, vacuum cleaner motors can also be damaged by moisture. If enough water is sucked into a machine that is not designed for wet cleaning, the motor is damaged, resulting in a permanent loss in suction power. Replacing a motor is sometimes more costly than purchasing a brand-new vacuum cleaner.

So treat your vacuum well and it will serve you loyally for many years. A little maintenance on your cleaner goes a long way.

But, if you’ve examined the hoses, bag, filter, and even inside the machine for damaged or obstructed components and your machine is still not taking up junior’s spilt cereal, maybe it’s time for a new one.

Please keep in mind that each vacuum is unique, and before implementing any of the recommendations above, please contact the manufacturer of your vacuum.

Related Questions

  • What would cause a vacuum to lose suction?

    Vacuum cleaners are simple devices. They need electricity to be transferred to the vacuum in order to generate a suction force capable of lifting trash. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.

  • What determines vacuum suction power?

    The main measurements used in suction power are airflow (CFM), air watts (AW), water lift (inches of H20), amps, and horsepower. It is the most important component of a vacuum cleaner. The suction motor, which turns electrical power into suction power, determines the suction power of your vacuum.

  • How do you fix a weak vacuum suction?

    Please check to see if any of the following will resolve the issue.

    1. Check the dust container.
    2. See if the filters are clogged. .
    3. Please reference your vacuum cleaner’s user manual for further information about the filters.
    4. Check the hose for blockage.
    5. Check the hose for cracks or tears.
    6. Check the brush or roller for clogging.
  • How do I make my vacuum suction stronger?

    Emptying the dust collecting bag is one of the simplest methods to boost vacuum cleaner suction. Dust containers must have adequate area for ventilation otherwise they will get clogged and have reduced suction strength. Check your dust compartment on a regular basis and empty or replace it when it is 70-80% filled.
