To understand why air rushes into a vacuum cleaner nozzle we need to trace air flow in the machine. Let's do that.
The motor in a vacuum cleaner spins a fan, and the fan moves air. The air intake for the fan is connected to ducting that is routed to the nozzle. As the fan forces air out in its exhaust stream, it creates low pressure on the suction side of the fan. This low pressure (a partial vacuum) is felt along the air path to the nozzle. At the nozzle, outside air pressure forces air into the ducting where air pressure is lower. The moving air has picked up debris and carries it along. That debris ends up in a bag or filtered dirt canister or someplace else where it can accumulate and be collected for disposal.
This applies to machines that have bags or filters to get the debris out of the air stream before it goes through the motor to keep it cool. Some machines isolate the motor from the air stream created by the fan, and the motor is cooled by another fan. These "direct" vacuums operate in a way that sees the air stream and the debris pass through the fan and be driven into a bag.
The operation of the fan has created a low pressure area along the ducting between it (the fan) and the nozzle. Outside air pressure, being greater than the low pressure created by the fan and ducted to the nozzle, forces air into the nozzle.

How is air pressure used in a vacuum cleaner?
Air pressure is used in a vacuum cleaner to create suction. The motor inside the vacuum cleaner generates a lower air pressure inside the machine, causing outside air to rush in with force through the nozzle. This rapid movement of air allows the vacuum to pick up dirt and debris from surfaces.
Why does a vacuum blow instead of suck air?
A vacuum cleaner creates suction by lowering the air pressure inside the vacuum, causing higher pressure air from the surrounding area to rush in and fill the space. This rushing air creates the sensation of air being "sucked" into the vacuum cleaner.
How do vacuums work?
Vacuums work by creating a low-pressure area inside the vacuum cleaner using a motor and a fan. The low pressure causes air to rush in through the vacuum cleaner nozzle, carrying dirt and debris with it. The dirt and debris are then collected in a filter or dust bag, and the clean air is released back into the room.
How does suction work in a vacuum cleaner?
Suction in a vacuum cleaner is created by a motor that generates airflow. This airflow creates a low-pressure area inside the vacuum, causing air and particles to be sucked in through the nozzle and into the vacuum's dust bag or container. The suction power of the vacuum cleaner is determined by the strength of the motor and the design of the airflow system.
How atmospheric pressure responsible for the sucking effect of vacuum cleaners?
Atmospheric pressure pushes air into the vacuum cleaner and creates a higher pressure inside the cleaner compared to the surrounding atmosphere. This pressure difference causes air to rush into the vacuum cleaner, carrying dust and debris along with it. The force of the rushing air creates the sucking effect that allows the vacuum cleaner to pick up dirt.

Can a vacuum cleaner work in a vacuum?
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
Why is a vacuum cleaner called a vacuum cleaner?
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.
How does a vacuum cleaner separate dust from air?
A vacuum cleaner separates dust from air using a combination of suction and filtration. The dust-laden air is drawn into the vacuum cleaner through the suction nozzle, where the larger particles are captured in a filter or dust bag, while the smaller particles and debris are trapped by a series of filters to prevent them from being released back into the air.
How do you spell vacuum?
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.
Is a vacuum cleaner more like a hair dryer?
No. A vacuum cleaner sucks in air. A hair dryer blows out air.
How do you spell vaccum?

Inside all vacuum cleaners is a high speed fan.explain how this fan causes the vacuum cleaner to pick up dirt?
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.
