How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
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.
This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well. Dirty filters – a clogged or dirty filter can also be the cause of your cleaner being noisier than usual.
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.
Unclog the filters
Blocked filters are one of the most common causes of suction loss, so check and clean both filters – the allergen filter, normally found closer to the dust bag or container, as well as the motor filter, usually situated at the back, near to the vacuum exhaust.
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.
Check that the brush bar is clean and not damaged
If the cleaner becomes noisy or starts vibrating, it may be because some debris has got tangled around the brush roll or agitator situated in the bottom of the cleaner.
If there is a clicking sound when you rotate the side brushes manually (with the side brushes on). It indicates that the noise is from the side brush motor. Replacing the side brush motor could fix the issue. You can refer to the video about how to replace the side brush motor to replace the side brush motor.
Removing a clog
Use a pair of pliers to make one end of the hanger into a hook shape. Put the end of the hook into the hole where the vacuum where the clog is located. Push the hook down until it won`t go any further. In some cases the hook will go all the way through and push the clog out the other side.
Hold the floor tool as best as you can using your foot and twist the metal pipe.. this should `break the bond`. As soon as you have movement after twisting the pipe, you should find that it pulls free.
You Need to Change Suction Power Settings
One of the most common reasons for a vacuum that`s hard to push is using the incorrect suction setting. Most people want to use the maximum suction setting all the time, when in some cases this isn`t necessary.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
Generally, a timing belt that goes bad makes a noticeable ticking or clicking timing belt sound that is unusual. When the timing belt starts falling the ticking or clicking sound becomes pretty audible.
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.
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.
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.
Vacuum cleaner motors can sometimes start making noises of either a dull or piercing kind. Dull sounds can be caused by hair or pieces of string getting wrapped around the impeller, preventing the motor from turning properly. Piercing noises are normally associated with worn motor bearings.
Vacuum cleaners have a decibel rating that ranges from approximately 64dB to 80dB. Most vacuums fall in the 70dB to 80dB range, with uprights tending to be the loudest. The quietest vacuums are always cylinder models that are designed to minimise noise output (and often have “silent” or “quiet” in the product name.)
If you listen very carefully, sometimes you can hear a “hiss” sound that is the signal of a vacuum leak. However, the most common way to notice this is when the engine loses fuel efficiency. The reason for this is due to the fact that vehicle exhaust is delayed on exiting the combustion chamber.
Hissing or Suction Noises
Another sign that a vacuum hose is leaking in your engine is strange sounds. Specifically, you may hear hissing, squealing, or suction. The volume of the noise depends on how bad the leak is. For example, if you have a minor vacuum leak, you may not hear the hissing at all.
The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
If possible, wash it in warm water. You may be able to remove and wash the hose, wand and accessory heads too, if they`re very dirty. Make sure all parts are completely dry before you put the vacuum cleaner back together.
Attachments are quite easy to clean – just fill a sink or bucket with warm water and about a teaspoon of dish soap and drop them in. For any attachment that has hair stuck in it, you can use your cleaning toothbrush to brush it away.
Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
Also known as the power nozzle, the power head is found at the base of most vacuum cleaners. These frequently offer brushroll height adjustment capabilities for cleaning different floor types. Different types can clean any surface, from bare floors to deep-pile carpeting.
