How to choose a good vacuum cleaner? It needs to be screened from the appearance of the vacuum cleaner, accessories, suction, and the prevention of secondary pollution.

Vacuum cleaners are generally divided into three types: barrel vacuum cleaners, canister vacuum cleaners, and handheld vacuum cleaners, dry wet vacuum cleaners. They are used in different places. The vacuum cleaner generally uses a motor to drive the impeller to rotate at a high speed, so that a partial vacuum is formed in the dust collection chamber. Air pressure difference is formed with the dust collection chamber to generate airflow. Dust is sucked into the dust collection chamber together with the airflow. After filtering, the dust is retained in the dust collection chamber and the clean air is discharged.


How to choose a good vacuum cleaner?

1. The suction is strong enough. The unit of suction is represented by the degree of vacuum. The greater the vacuum, the greater the suction. Generally expressed in pa (Pa). It is better to use around 27Kpa for home use. Too low and not enough suction. Too high is a waste. Handheld generally reach 16Kpa on it. When you go to the mall to buy, it is best to find a demonstration of on-site water absorption, bowling, and vacuuming.


2. Prevent secondary pollution. The inhaled dust is not filtered effectively and causes secondary pollution, which is a big invisible killer of vacuum cleaners!  Filter material for vacuum cleaner exhaust. 


* Sponge: The worst filterability. 

* Activated carbon filter: It can increase the adsorption force of dust, but the filterability is average with large holes. 

*Sterilizing cloth: the texture is relatively fine, it is a relatively economical material, and its performance is better than the first two. 

*HEPA filter: the high-precision filter has strong adsorption and is currently the best filter material. 

*Composite paper dust bag: Double-layer filtration effectively improves the dust filtration rate, but the disadvantage is that the cost is too high. The advantage is that it is convenient to use and can be thrown away without cleaning when it is full of dust.


3. Air purification and sterilization technology. Electrostatic dust collection, HEPA micro dust purification, activated carbon adsorption, photocatalyst (need sunlight to regenerate), cold catalyst (natural regeneration) recommended! Catalyzed decomposition of formaldehyde.


4. Equipped with multiple suction nozzles. See if the vacuum cleaner is equipped with a nozzle suitable for your cleaning needs. Of course, the more complete the equipment, the more applicable occasions.


5. Other details. Whether the material of the vacuum cleaner shell is strong and durable. Stainless steel is preferred (disadvantage of high price), and ABS engineering plastics are recommended for wear resistance, impact resistance and aging resistance. To verify the material, you can open the upper cover of the dust collection bin, and see if there is ABS written inside it, except for fake and shoddy! Check to see if there is a dusty display, if there are rubber rollers to prevent scratches on the floor, and if it can be adjusted with infinitely variable speed. Whether the fuselage is designed with anti-collision strips to protect your furniture. If there is a dust bag, it depends on whether the quality of the dust bag is good, and non-woven materials are recommended. Now the latest vacuum cleaner technology is a dust-free bag design. Through the principle of aerodynamics, the dust sucked into the dust collection bucket is thrown into the dust collection bucket by strong centrifugal force, so as to realize the complete separation of dust and air, and effectively solve the secondary problem. Pollution problem, the dust collection efficiency is 25% higher than ordinary vacuum cleaners, highly recommended (also known as dragon whirlwind, or dust rejection technology)!
