I believe everyone is familiar with vacuum cleaners. Due to the continuous advancement of science and technology, vacuum cleaners have become a kind of air purification products that win people’s favor in modern life. Generally speaking, vacuum cleaners are a kind of electrical appliances that suck dust. Yet how much do you know about it? How do we choose vacuum cleaners in our daily life?
We know that vacuum cleaners can be divided into horizontal vacuum cleaners, vertical vacuum cleaners, hand-held vacuum cleaners, bucket vacuum cleaners, rod vacuum cleaners and robot vacuum cleaners according to their shapes. According to the filtering method, vacuum cleaners can be divided into dust bag type, dust cup type, HEPA filtration and water filtration type, in which the dust bag type and dust cup type are vacuum cleaners with dust bag and vacuum cleaners without dust bag as we know it.
Vacuum cleaners with dust bag means that there is a dust bag in the machine (some are paper bags and some are cloth bags). All the dust that is sucked is in the bag. When the bag is full, if it is paper bag, you need to replace the bag with a new one. (the paper bag is disposable) If you use up all the paper bags, you need to buy some more from the store. But if it is cloth bag, you need to wash and dry the bag before you put it in the machine again.
Vacuum cleaners without dust bag means that there is a dust box in the machine. When the box is full, just Just take it out and rinse it with the tap water, you don't need to change the box.
There is of course a difference between a vacuum cleaner with dust bag and dust-bag-free vacuum cleaner. The former simply collects dust while exhausting the air. After the dust bag is filled, the reminder on the machine will remind you to change a new bag. The suction performance of this type of vacuum cleaner is not good.
The basic principle of the dust-bag-free vacuum cleaner is the same as the one with dust bag. The difference is that vacuum cleaner with dust bag separate the large dust by the rotating centrifugal force of the airflow after the dust is sucked into the dust box, and then keep the fine dust in the dust box through the internal filtering device while allowing air to flow out. The suction performance of this type of vacuum cleaner is much better than the ones with a dust bag, and the service life of the motor is longer. People usually will chose vacuum cleaners without dust bag in their house.
Vacuum cleaners with or without dust bags all have its own benefits. The former is more convenient while the latter is cleaner. Pick one you like most.
