The vacuum cleaner, ally of cleaning.
A vacuum cleaner is a device that allows something to be sucked up . Generally the concept refers to the appliance that is used to clean an environment since it removes dust from surfaces .
To understand what a vacuum cleaner is, you need to first focus on the idea of vacuuming. This verb refers to capturing outside air or creating a current of a gas or other fluid through the generation of a pressure drop.
The vacuum cleaner, also known as a vacuum cleaner , uses an air pump to absorb dust . Dust is called, meanwhile, the dry dissolved earth and the particles of solid elements that remain as residues .
How a vacuum cleaner works
Although these devices may have different characteristics, their operation is usually similar. Vacuum cleaners have a motor that starts a fan , which lowers the air pressure inside the device. This vacuum that is created causes air to enter through the vacuum cleaner hose.
The dust that accumulates inside the appliance, on the other hand, can be filtered in different ways. One of the most common mechanisms consists of installing a porous bag that traps dirt by filtering the air .
Another filtering method involves making the air rotate at high speed in the tank so that the particles fall to the sides, where they are collected. There are also vacuum cleaners that cause dust to remain suspended in water droplets, which rise and are captured after shaking.
cleaning robot
The first vacuum cleaners were created at the beginning of the 20th century . Those machines, like the rest of the models that were marketed for decades, had a suction nozzle that had to be dragged along the floor to suck up the dust.
Whoever uses a vacuum cleaner of this type, then, must take the tube connected to the nozzle and pass said nozzle over the surface to be cleaned. The task has to be done manually.
Technology at the service of cleaning with vacuum cleaners.
In the mid- 1990s , however, robotic vacuum cleaners began to be marketed. These are autonomous robots , capable of operating with a certain autonomy .
The most modern robotic vacuum cleaners have sensors that allow them to detect dirt and avoid obstacles. Thanks to artificial intelligence , these vacuum cleaners clean without needing a person to guide or direct them.
Roomba, the most popular robotic vacuum cleaner
With millions of units sold worldwide, Roomba is the most famous robotic vacuum cleaner. This product is manufactured and marketed by iRobot , a company of American origin.
The most advanced Roomba models have double brushes, several sensors of different types and WiFi connection. These vacuum cleaners can rotate 360º and reach hard-to-reach corners.
Robotic vacuum cleaners can store data and create maps . In this way, they recognize the surface they have already cleaned and maximize their efficiency when moving. There are Roomba series that work with an application called iRobot Home : this app is used to determine specific areas in each room, allowing the vacuum cleaner to go directly to those corners (for example, under a table or behind a sofa).
