How bagless vacuum cleaners work?

Yes, each vacuum cleaner works in plenty of different ways. They are largely dependent on the type of suction and their filtering methods are adopted. These days plenty of modern vacuums use plastic bins instead of bagged ones because emptying them is an easy job. It only tells us that they require filters to separate the dust from the air.

Here we will know about a few main types of bagless vacuum cleaners and how they work.

The direct fan type

The direct fan type is the most common one in the bagless vacuum niche. It usually either uses a bag or canister for dust storage. It has a direct fan that vacuums dirt with a large impeller placed close to the brushbar. This type also has a cylindrical brush which is generally located at the front bottom of the device.

The dirt that is drawn out of the carpet or other surfaces through the impeller is flustered. Then it tends to deposit either with a direct approach or with a filter into its storage container. As it has a low suction power and basic filtering system, it might not be an appropriate choice for the domestic environment.

The cyclonic vacuum cleaners

These vacuums are very much different from direct fan types. They do not separate the dust with a series of impellers and bag filters. Instead, they dispose of the exposing dirt-filled air to large centrifugal forces, meaning they move away from the centers into a specialized collection vessel with a certain angle, this works by the cleaner sucking in airborne dust.

The air is forced to produce a fast-spinning vortex by this process through the centrifugal force. And because of this, the dust particles get trapped within it to move to the outside of the body. After being freed from the air vortex once, for later disposal the dirt falls to the base of the container through gravity.

Robotic vacuum cleaners

These circular vacuums tend to operate naturally with different sorts of positional, acoustic, and visual sensors by doing a bit of observation of the room, and then they start sweeping the floor periodically. These devices have units that typically use impellers, a series of filters, and compressed bins to draw dirt through their brooms and brushes. They do all these willfully before storing it for later manual extraction.

As these products are small-scaled in nature, so people use them frequently for small residential or medical applications. Although their suction volume and intensity has no similarity with the direct fan type or cyclonic vacuums. Also, they are not capable of accepting attachments usually which can stop their convenience. These vacuums are the most recent addition to the vacuum market.

How to clean a bagless vacuum cleaner?

There are a few steps which you need to follow in order to clean your bagless vacuum cleaner.

1st step

You need to gather some tools and supplies for this process.

  • Dust cloth
  • The manual of the device
  • A single can of compressed air
  • Screwdriver
  • Dish soap
  • Scissors
  • New filter
  • Elbow grease

2nd step

First, we need to break down our vacuum cleaner. To do that we should start with removing all the washable and replaceable parts. As most people have upright models, so parts that have to be removed are the bin, the secondary cyclone piece above the dust bin, every additional attachment, the pre-motor filter, and HEPA post-motor filter, etc.

3rd step

You can wash every part (that can be washed) of your device with soap and water, the remaining parts can be cleaned with a dust cloth. Also, don’t forget to replace your vacuum’s HEPA filter fully every 6 months.

4th step

Those who own a bagless vacuum should know that the dust bin is not sealed. Which only means the inner compartments of the product can attract a lot of dust. If you give them a blast with a can of compressed air I am pretty sure it will clean them completely. But this step needs to be done quickly as after a while the can of air becomes cold.

5th step

This part includes removing the rotating floor brush and cleaning them. To clean the rotating brush one needs a scissor to cut it. By doing a hard tap with fingers the lint and debris from the bristles of the brush can be cleaned. While doing all these you can also take a moment to check your vacuum’s drive belt for wear and tear, cuts, or stressed areas. If there is any damage then you can replace it.

6th step

This step involves checking the air passageway for clogs before you reassemble the floor-brush of your vacuum. On most devices behind the floor-brush, there is a small circular air passageway. This passageway is known to be the main suction path for dirt and debris while you clean the floors.

If you want to make sure that the product you own is working properly then this airway should always be free of obstructions. You should also check the vacuum-hos for blockages and remove all of the debris that is trapped there.

After washing all the vacuum parts, and when they have dried fully, you are allowed to re-assemble your vacuum and install a new HEPA post-motor filter.
