How to Increase Vacuum Cleaner Suction

With time, the vacuum cleaner starts to get rave-up, and the suction feature doesn’t work as active as before or when you first got the machine. There is nothing more frustrating than when your cleaner still leaves debris on the carpet or floor while cleaning. 

It's a pervasive problem in every household. If you have faced this problem with your vacuum cleaner, then you probably have browsed the internet to find a solution for it, or maybe you’re thinking of replacing it with a new that has good sucking power. 


Buying a new vacuum cleaner isn’t going to make any difference, unless if you know how and why a vacuum cleaner loses suction in the first place. 

So, what exactly improves your vacuum cleaners’ suction power? Let’s check out this pro tips guide to know more about increasing vacuum cleaner suction.

How to Improve Vacuum Cleaner Suction Step-by-Step

1. Empty the Bag

Emptying the bag is very important to improve the suction power of a vacuum cleaner. It is very wise to the idea to check if the bag is full regularly.

However, focusing on the fill line is the best trick. The fill line is found at the front for those with bagless vacuums. The fill line is on the vacuum bag for those with canister and upright vacuums. 

There might be times when there are dirt and hair filled up over the fill line collection spot, which means there isn't enough room for more stuff to collect. That is when you need to empty the bag. 

Even if the bag doesn't look like it's filled up, the fill line is all you need to check. Although, the vacuum will continue making sounds which will imply that it is working correctly. But this doesn't mean the suction is working fine.

2. Use the right setting

Sometimes emptying the bag isn’t everything; it requires using the correct settings as well, specifically the height setting. 

Not many users know about this, but poor vacuum suction performance usually results from using wrong height settings. 

For instance, if you're vacuuming floors made from wood, tiles, and other hard flooring materials, you shouldn't use higher settings. 

Such floors require lower height settings since vacuum cleaners deliver the most strong suction when they are seated closest to the floor. Always go with the "bare floor" setting to be on the safe side.

3. Try unclogging the hose

The suction still might not be useful, even after you have emptied the bag, and you've also cleaned up the filters. You’ll also need to unclog the hose. To fix this, check the tube and see if it's been clogged with dirt or hair. 

Then you could use a broom handle to remove any trapped debris. Tweezers are also handy for this job. If the hose is fully stretched out, then you can only insert the broom handle.

Don’t forget to inspect the tube from one end to the other to see if any cracks, kinks, or holes may cause the vacuum to lose its suction. 

However, it's advisable to replace the entire hose, if the hose has reached this extent including holes, cracks, and lots of hard -attached debris.

4. Maybe the vacuum isn't airtight

For a canister vacuum cleaner, the vacuum airflow starts at the hose tip, and for an upright cleaner at the base opening. These are the only places a vacuum should be letting in air. If there is airflow or leak found from any other part, it means the vacuum cleaner isn't a doing "vacuum" anymore. 

When the hose and other attachments are not as tight as they ought to be, air escapes usually happen. Therefore, as the user, you should try finding these spaces and tighten them up. For example, turn an upright vacuum upside down and inspect openings leading up into the vacuum body. 

Check if there are any papers or hair that may have jammed the path. Feel free to remove the rotating brush to gain better access to the opening. If the vacuum has been installed with it.

5. Clean the rotating brush

If for some reasons, the vacuum rotating brush doesn’t turn on, it's most likely this is the cause for poor suction power. Rotating brush’s main task is to sweep debris and dirt into vacuum cleaners airflow suction. The brush makes things easier for the cleaner to pick up trash. 

Therefore, if the rotating brush doesn’t spin as much as it is supposed to, then there'll be no suction, which will result in a corresponding loss of the vacuum's cleaning power. 

It is not easy to fix this. All you need to do is have the rotating brush removed and clean it. The rotating brush works better if it is adequately cleaned.

Nonetheless, worn out drive belt it's might be the reason behind the lack of better gyration and propelling of the brush might be because of a. Check it out and see if it is broken. Replace it with a new one if it is broken or damaged.
