How to Fix Loss of Suction in a Vacuum Cleaner
Since being invented in 1901 by a British engineer, Hubert Cecil Booth, vacuum cleaners have become vital in the battle for keeping homes clean. As more of us strive to remove as much dust, dirt and allergens as possible, manufacturers have been improving their models to offer us a better clean.
Yet, despite the advanced technology vacuum cleaners faults can (and do) still develop faults, with a common fault being a loss of suction. Such a fault will see your vacuum leave dust, dirt and various allergens such as pet dander, dust mites and pollen in your home — meaning your home isn’t as clean as it may appear.
Thankfully fixing a vacuum cleaner which has lost suction isn’t as difficult as it may sound, and there are generally 5 key reasons why the suction has been reduced. These are:
Blocked / Dirty Filter
Bag / Cylinder Too Full
Gaps in Air Flow
Blocked / Dirty Filter:
Most vacuum cleaners have at least one filter, the pre-motor filter. This is designed to stop harmful particles from getting to and damaging the motor in your vacuum cleaner. Due to the job the filters do they can quickly become dirty or worse, blocked — and in such a situation the suction of your appliance will be hindered.
Rectifying a dirty / blocked filter on your appliance is relatively straightforward. Once you’ve located where the pre-motor filter simply:
Remove it from your vacuum cleaner
Shake off any excess dirt
Wash the filter in warm water (if a washable filter is used, if not replace)
Allow the filter to naturally dry for at least 24 hours before placing it back into the vacuum cleaner. In addition to having the pre-motor filter, many also have a 2nd filter which stops fine dust / pollen particles from leaving the vacuum cleaner and re-circulating into the room. This filter should also be removed and cleaned by following the process above — although if either are considerably dirty it’s suggested you purchase a replacement vacuum cleaner filter and fit this to your appliance. NB: It is important to make sure you do not run your appliance without a filter; doing so can result in further faults developing.
Bag / Cylinder Too Full:
At first glance the capacity of your bag / cylinder may seem a lot, but it is worth remembering the fuller the bag / cylinder becomes, the less suction offered by your vacuum cleaner — as such, it is important to make sure you’re emptying the vacuum regularly.
As a rule of thumb, it’s recommended you empty both before they become two-thirds full. In addition to emptying your vacuum’s bag, it is also important to make sure you change it for a new one regularly. This is because the pores in the bag can become clogged by dust particles, which in turn significantly reduces the air permeability and the performance of your appliance.
Gaps in Airflow:
If you’ve noticed a distinct lack of suction from your model when you’re using the hose attachment, there’s a good chance you’ve got a gap in the airflow. Even the smallest hole can reduce the suction power offered.
Unfortunately, over time the hose on your vacuum can suffer from wear and tear which makes such gaps more likely — with pulling the hose too hard when using the vacuum being a common reason for splits and holes occurring. If yours is damaged in either way, you’ll need to get a replacement vacuum hose and fit this to your vacuum instead.
If after checking the four areas above the suction in your vacuum cleaner is still poor, there may be a fault with the motor or carbon brushes. In such a situation you will need to replace the motor / carbon brushes. Replacing the carbon brushes or motor on your vacuum cleaner can be a considerably time consuming and tricky task, which is why it’s recommended doing so only if it is really essential.By taking the time to regularly empty your vacuum cleaner bag / cylinder, clean the filters, and remove blockages you can keep your vacuum cleaner working at peak performance for years to come.
