The most critical part of the vacuum cleaner is the suction and filtration during the cleaning process. The suction ensures the cleaning effect. The filtration is to prevent secondary pollution, followed by the convenience of noise and garbage cleaning. So what factors need to be considered when purchasing a vacuum cleaner, let's introduce it next.
1. Power
The size of the power does determine the size of the suction power, that is, the working efficiency of the vacuum cleaner. If the suction power is too small, the dust and garbage cannot be disposed of too cleanly, so you need to buy a slightly larger suction power. The suction unit is represented by the degree of vacuum. The greater the vacuum, the greater the suction. Generally used pa (Pa) said. It is better to use 27Kpa for home use.
2. Motor
The motor belongs to the core component. The quality of the motor will directly affect the working efficiency and service life of the vacuum cleaner. Usually, we judge whether the motor is good or not by the vibration sound of the casing itself.
3. Noise
The noise of the vacuum cleaner is caused by the operation of the motor. It is most appropriate to choose the one with less noise, generally less than 80 decibels, when purchasing.
4. Sealing
Vacuum cleaners with good sealing are also more power efficient, and their suction power and noise will be superior.
5. Dust collection protection device
The dust bag or filter bag is a key part of the vacuum cleaner, but it is more easily damaged by metal objects. Some vacuum cleaners have electromagnets on the brush that attract small metals such as scrap iron, blades, needles, etc., so that they do not enter the dust bag.
