I Let me tell you how to choose a vacuum cleaner:

First, give a brief introduction to the vacuum cleaner

Working principle: The motor is used to drive the impeller to rotate at high speed to form a partial vacuum in the dust collection room. The air pressure difference between the dust collecting room and the dust collecting room creates an airflow. The dust is sucked into the dust collecting room along with the air flow. After filtering, the dust is retained in the dust collecting room and clean air is discharged. *Classification by shape: 1. Bucket vacuum cleaners, suitable for large enterprises and institutions, hotels, factories, construction sites, offices and other public places. 2. Horizontal vacuum cleaner, used for household cleaning or partial cleaning of companies. 3. The handheld vacuum cleaner can be used to clean dust on bookshelves, furniture, wardrobes, electrical appliances, cars, etc. It is compact and convenient. *Classified by function, 1. Wet and dry use. 2. Dry type. 3. Multifunctional, such as water filtration, disinfection, etc.

Second, how to choose a good vacuum cleaner?

1. The suction is strong enough! The suction unit is reflected by the degree of vacuum. The greater the vacuum, the greater the suction power. Generally expressed in pa (Pa). For home use, around 27Kpa is better. Too low suction power is not enough. Too high is a bit wasteful. The handheld type generally reaches 16Kpa. When going to the mall to buy, it is best to find one that provides on-site demonstrations of water-absorbing columns, bowling balls, and vacuums, which is more intuitive.

2. Prevent secondary pollution! The inhaled dust is not effectively filtered and causes secondary pollution, which is a major invisible killer of vacuum cleaners! (1) Look at the filter material of the vacuum cleaner exhaust. *Sponge: The worst filterability. *Activated carbon filter: It can increase the adsorption of dust, but the pores are large and the filtration performance is average. *Scouring pad: The texture is relatively fine, it is a relatively economical material, and its performance is better than the first two. *HEPA filtration: The high-precision filter has strong adsorption force and is currently the best filter material. *Composite paper dust bag: Double-layer filtration effectively improves dust filtration rate, but the disadvantage is that the cost is too high. The advantage is that it is easy to use and can be thrown away if it becomes dusty without cleaning. (2) Look at air purification and sterilization technology. Electrostatic dust capture, HEPA dust purification, activated carbon adsorption, photocatalyst (requires sunlight to regenerate), cold catalyst (natural regeneration) recommended! Catalytic decomposition of formaldehyde.

3. Equipped with multiple suction nozzles! See if the equipped nozzle suits your cleaning needs. Of course, the more complete the equipment, the more occasions it can be used.

4. Other details! . Is the shell material strong and durable? Stainless steel is preferred (disadvantage is higher price) * ABS engineering plastic is recommended for wear resistance, impact resistance and not easy to age. To verify the material, you can open the upper cover of the dust bin and see if the word "ABS" is written inside. Except for fake ones! (Whether the monitor is covered with dust) (Whether it has rubber rollers to prevent scratching the floor). (Whether it can be infinitely variable speed control). (Whether the fuselage is designed with anti-collision strips to protect your furniture) If there is a dust bag, check whether the quality of the dust bag is good. Non-woven material is recommended. *The latest vacuum cleaner technology now is the bagless design. Through the principle of aerodynamics, the dust sucked into the dust bucket is thrown into the dust bucket through strong centrifugal force, achieving complete separation of dust and air, effectively solving the second problem Secondary pollution problem.

The vacuuming efficiency is 25% higher than ordinary vacuum cleaners! Highly recommended! ! ! (Also known as dragon whirlwind, or dust removal technology)

5. Purchasing misunderstandings! one. Today's household vacuum cleaner motors are not high-tech products. The best motors in the world are produced in China. Using imported motors will only increase product costs and increase the burden on consumers. (This shows that some high-tech professional dust motors are imported and very good.) On the other hand, the motor is installed inside the machine, and there is no place of origin marked on the outside. Therefore, some brands advertise themselves as imported motors, which is deceiving customers. It's very simple. You ask the salesperson to mark "imported motor" on the invoice and see if he dares? two. Regarding suction and noise. The correct noise reduction method is achieved by reforming the motor to use a relatively quiet motor. In order to achieve the purpose of noise reduction, some vacuum cleaners on the market have to sacrifice suction power and wrap several sponges around the motor to achieve a silencing effect. This way, the sound is smaller, but on the other hand, it affects the suction power (the exhaust is not smooth) and also affects the performance of the motor. Heat dissipation, causing the motor to be easily damaged! This is completely the wrong approach. The national standard is 82 decibels. Without using wrong noise reduction methods. It is better if it is lower than the national standard.

3. Things to note when using a vacuum cleaner!

It is strictly forbidden to inhale unextinguished cigarette butts, large balls of paper, etc., to avoid burning out the dust filter device and damaging the motor. * Each continuous use time should not exceed 2 hours, which may affect the life of the motor. Some models have overheating protection devices. When the overheating protection is activated, the machine should be shut down for 20-30 minutes before restarting. *Please do not block or cover the air exhaust vent when using it, and do not block the air inlet to avoid affecting the exhaust air and causing the motor to overheat and burn. If there is a dust full indicator, the dust collection chamber must be cleaned immediately after the dust full indicator. *General household vacuum cleaners cannot be used to absorb water and dust (such as flour, cement dust, wall powder, etc.) otherwise the motor will be damaged. Note: Except for professional water-absorbing and industrial vacuum cleaners!
