The different parts of a vacuum cleaner are a mystery to most people. Almost everybody has these household devices to fulfill their daily cleaning duties and the occasional deep cleaning. In this article, we’ll explore the wide range of parts that make up your vacuum cleaner so you can understand how they work from the inside out, and to protect it from damage, especially if it is a top-tier vacuum cleaner.


  • Bagged vacuum cleaners comprise six main parts, including angled fan blades, a porous bag, an exhaust port, an intake port, an electric motor, and a housing unit. Extra attachments include brush heads, vacuum hoses, and angular suction tools.
  • Bagless vacuum cleaners are made of similar parts with a few different things, such as not having a porous bag.
  • Most parts of your vacuum cleaner can be replaced by a professional, but it’s probably better to buy a new vacuum cleaner instead if you have a lower-end model.

The Internal Components Of A Vacuum Cleaner

Nearly all brands and manufacturers will include the same parts. Vacuums are created with an almost exact “blueprint” based on a simple list of components that have been in use for years. However, all brands don’t offer the same peace of mind you get when you register a Dyson vacuum.

Debris from carpets doesn’t stand a chance against vacuum filters.

The Parts of a Vacuum

While there are a few small parts in the mix, the main components of bagged vacuum cleaners are found below. A little later, we’ll go over bagless vacuum cleaner parts, as well, since there are a couple of crucial differences between the two types of vacuum cleaners. Understanding the different parts of a vacuum is important, especially for things like vacuuming hardwood floors.

The Angled Fan Blades

Airplane propeller blades inspire the air blades in your conventional model. Those angled blades are in charge of creating suction power and keeping air moving steadily through a standard vacuum.

The Intake Port

The intake port provides a steady stream of air so that the vacuum can maintain suction power. The speed at which air sucks into the unit is directly proportional to the speed of the fans.

The Exhaust Port

The exhaust port provides an opposite but complementary function to the intake port. This is the spot where the stream of air is allowed to flow back out.

The Electric Motor

Without the electric motor, your vacuum cleaner would suffer from a severe loss of power. This is an essential element of modern-day models. Most motors will operate with upwards of 1800 watts. The lower-end units will hover around 1600 watts.

The Porous Dust Bag

Debris from carpets doesn’t stand a chance against vacuum filters. Porous dust bags are a feature found in bagged vacuum cleaners and are precisely where their name comes from. They filter out loose dust, dirt particles, and other air particles that are undesirable.


Canister vacuums can be less hygienic than their bagged counterparts

What Makes Bagless Vacuum Cleaners Different

There are only a few key differences between a bagged vacuum and a bagless vacuum. The parts are mostly the same save for the exception we’ll go over below.

The Dirt Collecting Bin

Also called a dust canister, this is a feature typically seen in upright stock models. Canister vacuums can be less hygienic than their bagged counterparts. However, a perk of canister vacuum cleaners is that you can easily see the dirt level inside of them. This makes knowing when to empty the canister easy.

How do vacuum cleaners work?

Vacuum cleaners work by creating negative air pressure. The negative pressure causes air outside to flood in, evening out the vacuum’s internal pressure.

What are the most common parts of a vacuum cleaner that need to be replaced?

There are a few parts that might need replacement over the lifetime of your vacuum cleaner. These are the most common parts:

  • Motor
  • Power Cord
  • Bag Slide
  • Bottom Plate
  • Bellow

What should I do if any of the parts of my vacuum cleaner break?

It is recommended for lower-end models that you just replace the entire unit. It is far cheaper and much less effort than buying and replacing parts yourself or hiring an expert to do it for you. However, for a higher-end or luxury vacuum cleaner, contact the manufacturer. They can either fix it for you if it’s under warranty or direct you on how to have it done either by yourself or by an outside expert.

Should I try and fix my vacuum cleaner myself?

Make sure that you understand your warranty if you have one. Attempting to fix a broken vacuum cleaner yourself can void any warranty the manufacturer may have provided. Always contact the manufacturer to ask what your next step should be. For a lower-end unit, or in the case of no warranty, you may want to hire a professional to do it for you.

STAT: HEPA filtration-equipped vacuum cleaners can capture almost 100% of particles and allergens as small as 0.3 microns. (source)
