How to Identify and Fix Common Vacuum Problems ?

Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
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.
It is important to check your vacuum filter regularly and replace it when necessary. A clogged air filter will decrease the suction power of your vacuum cleaner and make it less effective at removing dirt and dust from your home.
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.
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.
The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
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.
A good rule of thumb is to replace the main filter every 3 to 5 years or when you see vacuum performance drop to an unacceptable level.
When you use a vacuum cleaner without a HEPA filter, these particles are stirred up and put back out into the air through your vacuum`s exhaust. Regular filters can`t remove these harmful particulates and this puts the people in your home at risk.
Boil old suction cups to revive them.
Take the pot off of heat and drop your suction cups in for about 30 seconds. Take them out with a pair of tongs and pat them dry on a lint-free towel. Try to use the suction cups right after you dry so they`re still warm and flexible.
Suction is the measure of pressure created by a vacuum motor measured in inches of water lift. Air flow is the measure of air volume flowing through a system measured in CFM or cubic feet per minute.
Air watts are a European test standard (IEC60312) for vacuums. An upright vacuum cleaner should be around 100 air watts and a cylinder vacuum cleaner needs to be about 220 air watts.
So a 1000W vacuum cleaner will use 1 kilowatt (1000 Watts) of electricity in 1 hour. The point here is that it is a consumption measurement, rather than a power output measurement… it tells you nothing about suction. If you want to use more electricity, then use a vacuum cleaner with higher wattage.
Vacuum suspension uses an active pump to create a negative pressure differential that doesn`t depend upon the prosthetic leg position. In a suction socket you still have some movement, but with elevated vacuum you eliminate almost all pistoning. Suction suspension basically is just a sealed chamber.
The most effective way to determine if your water filter is working properly is to test your water before and after it passes through your filter. Such analysis is called performance testing because it tests the effectiveness of your filter in reducing or removing potentially harmful contaminants that pass through.
Vacuuming can release and re-introduce pollutants back into your air, while washing the filters could potentially cause mold to grow if the filters are not dried fully. The only way to keep your filters fresh is to replace them regularly.
You`ll need it—the filter prevents dust from blowing out of the top while you`re cleaning. For wet surfaces, however, you`ll need to remove the filter entirely. Liquids will damage filters, and you could even potentially ruin your vacuum if you suck up water before removing the filter.
First, be sure to change the filter regularly – as we mentioned before, this is key to preventing clogs. Finally, if you generally have low water pressure in your home, this can also lead to clogs, so be sure to have the water pressure checked.
All you have to do is dab a little petroleum jelly into the cup and hold it in place wherever you`re attempting to stick it. Yup—it really is that simple. You might be wondering why petroleum jelly is so effective in making suction cups stick.
Add a few drops of soap or detergent into a bowl of hot water. Submerge the filter and squeeze it so it absorbs the cleaning solution. If the water becomes dirty, empty the bowl and refill with more soapy water. Once the water runs clear after soaking the filter, take it out and rinse the suds away.
The more air flowing through a vacuum, the better, which therefore means that the higher the airflow rate, the higher the cleaning power. An average airflow rating for a vacuum cleaner sits between 50 – 100 CFM.
