How to Identify and Fix Common Vacuum Problems ?

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

Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. 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.
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.
One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.
The most common cause of vacuum cleaner not picking up dirt properly is clogged air filter. Remove the filter and either clean or replace it as needed.
Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
Check the Rotator Brush and Wheels

Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.

All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor. The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle).
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

Your filters get clogged with bacteria, dust, smoke, mold, and other particles. These can all affect the air quality in your home as well as the performance of your vacuum`s cleaning abilities, if the filter is clogged you will find the suction and general performance of your vacuum will be minimized.
Many reasons can cause low refrigerant suction pressure, i.e.: low indoor temperature, dirty filters, restricted ducts, undersized ducts, closed dampers, frosted coils, restricted refrigerant line, restricted piston, incorrect piston, restricted strainer, bad indoor blower motor ect.

Need Kirby Generation 3 Vacuum cleaner manual. Vacuum is not picking up dirt from floor. Seems to have enough suction to inflate the bag, but when you check the suction under the vacuum, there seems to be extremely litle suction.
ANSWER : If your brush roll is turning and your bag is not overly full, then the only other thing it can be is a clog where the bag connects to the vacuum. Turn the plastic part out away from vacuum and lift off to see if you have something clogging it. It would have to be something big, but not so big that it could not get past the fan. As a rule of thumb, KIRBY never clogs. I suspect that your belt is stretched out and your brush roll is not turning while on the carpet so the brush roll is just in the way rather than brushing your carpet to pick up dirt.

Kirby generation 3 fan
ANSWER : You have to take off the top cover, then the handle pivot. Look down at the back of the armature you will see that it has a flat spot, you use a small vise grips or pliers to hold it, turn the belt pulley to the right if I remember right and turn the pulley off. If it won’t come free, use a couple of flat blade screwdrivers and pry up to pop the fan off. Then put it all back together.

My kirby generation 3 wont come on
ANSWER : Make sure cord is not damaged. Check to see nothing is blocking hose or carpet nozzle(where beater brush is or brush roll). Plug unit in to a receptacle that you know has power going to it. (Lamp you know works when plugged into same. Using hose on front, make sure bag bottom completely attached to exhaust, the hose has a little arm like thing that will depress the safety switch on the front of the unit, and turn on using foot switch at the back of the unit. If these do not work, it could be one of two safety switches, dirt may have fouled or switch may need to be replaced.
