By creating suction
The high-speed fan creates suction within the vacuum cleaner, pulling air (and dirt) into the machine. As the dirt-laden air enters the vacuum, it passes through a filter that traps the dirt particles while allowing clean air to continue through the machine. This creates a vacuum effect that sucks up dirt and debris from surfaces.
The fan powered by a motor creates suction which pulls the dust into nozzle (head) into the bag, filters or cyclones. The fan creates airstream with on its turn creates vacuum at the topside and front site of dust and soil particles so the will be lifted and transported by the airflow.
In a vacuum cleaner, the DC motor powers the fan that creates suction. As the motor spins, it drives the fan blades, which pull air and debris into the vacuum. The debris-laden air then moves through the vacuum cleaner's filtration system, trapping dirt and dust while the clean air is released back into the room.
Electrical energy is transformed to mechanical energy.
A propeller attached to the motor creates a vacuum (sucks air in) via an inlet. Within the cleaner itself there is an inline filter and receptacle, somewhere for the dirt to drop into. The filter prevents dirt particles meeting the fan and motor. When the motor is switched off the vacuum is reduced to zero and all heavy material drops in the receptacle light particles stick in part to the filter and can be removed manually to a waste disposal
Although it is called a vacuum cleaner, it does not actually create a vacuum. Inside the cleaner there is an electric motor which drives a fan blade. This fan blows air out of the vacuum cleaner and this causes air to be drawn in to the cleaner at the other end. Thus the cleaner works by creating an air flow, not a vacuum.
The fan in a vacuum cleaner moves air and creates an air stream. This moving air will entrain dirt and debris as the machine moves over the floor. The roller agitates the fibers of any carpet to loosen whatever might be stuck inside the loops of the pile. It's the ability of the moving air to catch smaller, lighter stuff and draw it into that moving air stream that makes the unit work. That debris will be directed to a bag, filter or something else.
The machine gets its name from the fact that the fan in the unit moves air and creates a low pressure pathway (a vacuum, though a partial one) that is open at the nozzle (or hose, when using accessories). Air rushes in at the opening of the pathway, and that moving air picks up debris. The air and dirt is then carried to a filter or bag, and the air get out to be returned to the room. Debris is left in the dirt tank or in the bag for disposal.
Just like that. The word "vacuum" is the spelling for a void, or emptiness. The "vacuum cleaner" uses a fan to provide lower air pressure at its nozzle, so as to trap dirt caught in the airflow.
In vacuum cleaners, pressure is used to create suction that pulls air and debris into the machine. A fan or motor creates a low-pressure area inside the vacuum, causing the higher-pressure air outside to push debris into the vacuum cleaner. This allows the vacuum cleaner to effectively suck up dirt, dust, and other particles from surfaces.

A vacuum cleaner has a fan driven by an electric motor in it. The fan moves air, and the moving air picks up dirt and carries it to the bag or dirt canister where it is stored until disposed of. The moving air is critical to the operation of the unit in that it is this moving air that actually picks up the debris and gets the carpet/floor clean.
