1. Look at the suction
The main function of the so-called vacuum cleaner is that it can vacuum, and "suction" is the key, so if you want to buy a suitable household vacuum cleaner, you must first look at the suction power. Generally speaking, the suction power of household vacuum cleaners is around 27Kpa, which is more suitable. Too low suction power is not enough, and too high suction power is a waste of electricity.
2. Look at the filter material
The structure of household vacuum cleaners all contain a specific filter material, the common one is sponge material, but this material has poor filterability; there is also an activated carbon filter, which can increase the adsorption force of dust, but especially the pores are smaller. Large, so the filtering effect is average; while the scouring pad has a finer texture, the filtering performance is better than that of sponge and activated carbon, and the price is relatively affordable. Therefore, this material can be considered when choosing a household vacuum cleaner.
3. Look at the shell material
Due to its high usage rate at home, it should choose a durable type, so here you have to pay attention to its shell material. Then here I tell you that stainless steel is the first choice because it is wear-resistant, impact-resistant and not easy to age.
4. Look at the noise reduction effect
Normally, the vacuum cleaner will make a certain sound when it is powered on. It's just that some of the sound will be relatively large and some will be relatively small, and the sound of a general vacuum cleaner is about 80 decibels. A better vacuum cleaner should only have the sound of wind after power-on, and the smaller the sound of the whole machine, the better, and should not be mixed with other noises. So pay attention to this when purchasing.
