Vacuum Cleaner Parts and Functions

Electric Motor

The electric motor gives power to the vacuum cleaner to run the fan via a drive belt. Most vacuum cleaner uses a motor that operates on 1600-1800 wattage.

This wattage decides the power and speed of the fan blade. A vacuum cleaner only runs smoothly if the motor is in good condition.

Maintenance of the motor needs to do after some time for good working. Good quality motors give long working life.

Power Source or Cord

Some machine uses a power source as a rechargeable battery, but the rest of the vacuum cleaner uses a long power cord.

The battery-operated vacuum cleaner is lighter and more portable but has limited power.

While plug-in cord power sources are heavy-duty machines, we must insert their wire plug into the socket to start the vacuum cleaner. It will lead to getting instant power.

So we don’t have to wait for the battery to recharge. These cords come in different lengths depending upon the type of vacuum cleaner.


Some canisters and upright vacuum cleaners come with a flexible hose, which increases the reach and facilitates ease of movement. The material of the hoses is plastic or a combination of plastic and rubber.

The hoses come with some attachments, which gives more efficiency in cleaning. The air comes from the main unit through the hose and connects to the extension tube.

Telescopic/Extension Tube

One end of the extension tube connects to the hose, and the other to the nozzle. There are many types of nozzles available on the market.

This extension tube helps to direct the nozzle in the desired direction. 

Internal Fan

The internal fan is located just behind the rotating brush of the vacuum cleaner. Its purpose is to guide the air from the filter to the dust bag.

When the angled blade of the fan spin, they suck the air and push air towards the exhaust port.


The power head is also referred to as a power nozzle found on the base of the vacuum cleaner. It can adjust brush roll height to clean different floors, like wood and carpet.

Some vacuum cleaners have a special powerhead, like a clogged port, that helps to remove any blockage easily.

Brush Roller

This brush roller is placed within the powerhead. It operates manually or automatically to clean the rugs, carpets, and mattresses. This roller can adjust per cleaning conditions or for the whole cleaning bare floor.


The most vacuum cleaner uses lots of attachment for better efficiency. The crevice tool, the dusting brush, and the upholstery tool are attachments seen in a vacuum cleaner.

Creative tools clean the narrow area under the bed or furniture, while upholstery tools clean the couches or drapes.

Dusting brushes are used to mop your bookcase, windowsills, lamp shade, showpiece, and framed art.

Speed Controller

It is a controller which controls the speed of the vacuum cleaner. As per the need, we can adjust the speed of the motor.

Suction Control

It is a control button that adjusts the suction pressure.


The headlight is the part of the vacuum cleaner located at the power nozzle.

The function of the headlight is to brighter the path of the cleaning area, which will help to determine whether that area is clean or not. It also helps to add light in crowded places, such as under the bed or furniture.

Control Module

The control module is also known as the digital display of the vacuum cleaner and is available on the central suction unit of the vacuum cleaner.

It helps to warn and alert the user regarding filter trouble, dust bag status, and another issue.

Drive Belt

The drive belt is used to link the motor with a rotating brush. It allows the vacuum cleaner to work steadily without any interruption.

So, we have to change it in 3 months for better machine performance.


Airflow from the exhaust port to our home contains lots of allergens, dust, and bacteria, which will affect our health. The vacuum cleaner uses a filter to overcome this problem and make our home bacteria-free.

Generally, there are two types of filters available.

1) True HEPA

True HEPA filters are used to trap almost 99.7% of bacteria and allergens whose size ranges up to 0.3 microns. It is more effective to make our homes pollutant and bacteria-free.

These filters are costlier than any other and are only available in the costlier models.

2) HEPA Style

HEPA Style filer is used to trap around 85-99 % of dust, debris, and bacteria. These filters are cheap and not as efficient as the True HEPA filter.

Dust Bag

The function of the dust bag is to collect dust and debris within it. Air escapes from the dust bag as it is porous and only dust and debris deposit. These dust gags are typically made-up of oven cloth or paper.

In some vacuum cleaners, the dust bag has two sections; one section is for solid particles, and another is for dust and debris.

ON/OFF Switch

The switch of the vacuum cleaner makes the machine ON/OFF. This switch can be placed at different locations of vacuum cleaners, and it purely depends upon the brand and model of the machine.

In some vacuum cleaners, ON/OFF switches on the canister and some on their handle.


These are the wheels of the machine. With these caster wheels, we can move the cleaner to any location to clean the floor.
