Usually, when we use vacuum cleaners at home, we use ordinary vacuum cleaners. Compared with the original sanitary tools, vacuum cleaners are not only efficient and effective but also convenient and fast. Nowadays, vacuum cleaners are more and more popular.

What is a vacuum cleaner?

The main components of the vacuum cleaner are a vacuum pump, dust collection bag, hose, and exhaust fan. Its working principle is that the suction fan in the vacuum cleaner rotates under the action of the current, which is what we usually say after power on. At this time, the vacuum state is inside the vacuum cleaner. Because it is in a vacuum state, the air pressure inside is much lower than that outside. At this time, the dust and particles on the ground will be pressed into the vacuum cleaner by the atmospheric pressure, that is, sucked in.

Then the garbage will be left in the dust collection bag after the filtration of the dust collection bag. Such a simple principle is convenient for every family. We just need to open the vacuum cleaner and easily walk around every corner of the floor with the vacuum hole. We dare not say that it is spotless. Most particles and dust are gone.

Tips for selecting and purchasing vacuum cleaners

• Choose according to the size of your home space and cleaning workload

Ordinary families, if they often take care of them, will not produce a lot of garbage every day. Generally, they do not need a vacuum cleaner with too much power. The power of household vacuum cleaners on the market is generally between 1200W and 2000W. Don't blindly pursue excessive power. The higher the power, the greater the noise, and the more power consumption.

• Pay attention to the vacuum degree

The vacuum degree is another important indicator of the vacuum cleaner. The greater the vacuum, the greater the suction. It is related to the quality of the motor and the sealing performance of the whole machine. The greater the vacuum degree is, the better. As the vacuum degree increases, the burden of the motor will also increase, which directly affects the life of the motor. Generally more than 20Kpa.

Precautions for using a vacuum cleaner

• The vacuum cleaner shall be used in a dry room or similar environment with an altitude of no more than 1000 meters, good ventilation, an ambient temperature of no more than 40 ℃, and no flammable or corrosive gases in the air.

• Before use, the hose should be properly connected to the suction port of the shell, and the hose should be tightly connected with the super long pipe and the suction nozzle at the end of the pipe, such as furniture brush, gap suction nozzle, floor brush, etc. Because there are few air inlets of the slot nozzle, the noise is high when used, and the continuous use time should not be too long.

• Connect the ground wire to ensure the safety of electricity use. The continuous use time of the vacuum cleaner shall not exceed 1 hour each time to prevent the motor from overheating and burning.

• When using a vacuum cleaner equipped with an automatic winding device, pull the power cord out to a sufficient length. Do not pull the power cord too far. If you see a yellow or red mark on the power cord, stop pulling it out. To rewind the power cord, press the button to automatically retract it.
