A vacuum is created by removing air or any other gas from a closed container, resulting in low pressure relative to the surrounding atmosphere. This can be achieved using a vacuum pump, which removes gas molecules from the container, creating a space where there are fewer air molecules present.
The first vacuum cleaner was invented in 1901 by Hubert Cecil Booth. He developed a machine that used suction to remove dust and dirt from carpets. This invention revolutionized household cleaning methods and quickly gained popularity.
A complete vacuum is created in the absence of matter, especially in gaseous form. The phenomenon of suction generally associated with a vacuum results from a pressure gradient. Since P=nRT/V and there are more moles of gas outside of the vacuum there is also a greater pressure outside of the vacuum.
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.
Vacuum is created in steam turbines to increase the efficiency of the turbine by lowering the pressure at the exhaust end, which allows the steam to expand and produce more work. This helps to generate more power from the same amount of steam.
The concept of vacuum was first discovered by Greek philosopher Democritus in the 5th century BC. However, it was not until the 17th century that Evangelista Torricelli created the first artificial vacuum using a mercury barometer.

Alcatel Vacuum Technology was created in 1952.
Schmalz Vacuum Technology Ltd was created in 2006.
The wet dry vacuum was created in the 1900's. They were created before the year of 2000, because they had all of the equipment they needed to create the vacuum.
