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.
air presure pushes dirt into the 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.
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 filter in a vacuum cleaner separates dust from air. Air is allowed to pass through whereas dust is trapped by the filter and caught in the bag/cylinder of the vacuum cleaner.
Both a vacuum cleaner and a tornado generate low pressure that pulls air inward.
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.

No there is no air in a vacuum cleaner
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.

No. A vacuum cleaner sucks in air. A hair dryer blows out air.

The make of vacuum is not as important as making sure that the vacuum cleaner is a HEPA vacuum. This stands for High Efficiency Particulate Air. They remove around 99.97% of allergens in furniture and carpets.
