How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

The exhaust filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner`s manual for cleaning instructions.
Why is the vacuum is blowing dusty air out of the back? Simple: the bag or canister is full and the vacuum has nowhere to store the dust it is collecting. Empty the canister or bag. If that doesn`t fix it, the vacuum filter needs to be cleaned or changed.
Airflow Issues

If the device is clogged, or the dirt cup is full, this may cause the unit to overheat. Unplug the unit and allow it cool, empty the dirt cup and clean the filter.

The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
There are several reason for your vacuum`s inability to pick up dirt. First check to see if there is a clog in your hose. You can try to place a quarter through the hose to see if there is a clog. If there is a clog you can use the end of a broom stick to gently push out the clog.
Why does my Shop-Vac® wet dry vac blow dust back into my room? The dust isn`t being stopped by the filter and is being exhausted out of the blower port and back into the air. This can be caused by a hole in the filter, the filter not being properly installed, or the dust being too fine for the filter.
If your Dirt Devil Gator (Model Number: BD10100) isn`t starting or staying on for more than 15 seconds, you may need to replace the battery. Follow this guide to replace the battery to keep your Dirt Devil Gator in use! However before using this guide, you may not need to full replace the battery, just charge it!
If there is something that has become caught in the hose in another part of the system, the airflow will be reduced and can cause overheating and a shut down. Clear out hoses, attachments, and brushes of any hair, dirt, and debris. This will allow for restored airflow and should get things going again.
Often when your machine is not picking up it is due to loss of suction. If your vacuum cleaner turns on but won`t pick up on carpet or bare floors, something is impeding suction. You may need to change the vacuum bag, unclog the hose, replace/clean the filters, replace the hose, change the belt, or repair the motor.

Bissell bagless sweeper sucks up dirt but will not put dirt in the canister cup. It will pickup until it clogs, then it will stop picking up dirt. It will really hold quite a bit of dirt before it stops completely up. Thanks for any help.
ANSWER : I had the same problem, called Bissell over 10 times! They send me 3 plastic inserts for the dirt chamber, not the problem. I solved it by throwing the Bissell away and buying a Eureka bagged vacuum, no more problems.

My electrolux oxygen cannister has the “bag change” light on when there is a new bag. The light stays on when the suction power is high (to pick up small particles) and it won’t pick up, but the ight goes off when the suction power is low (to pick up big objects). I changed the hepa filter, cleaned the motor filter and changed bags, but all that didn’t help.
ANSWER : You may have a clog in the hose, and/or the inlet by the brush roll. A clog will turn on that light as well as a full bag.

ANSWER : You need to replace the belt whenever the green brush indicator light goes out or is not steady. Be sure to observe the wear settings when re-installing the brush. The ends of the brush are marked with 1, 2, or 3 notches and numbers. In normal use the brush should have setting # 1 towards the rug. These settings adjust the brush for wear, and moving the bristles out prematurely will result in excess brush and belt wear.
