What is the function of household vacuum cleaner?

Household vacuum cleaners can absorb dust and purify the air.

The working principle of the vacuum cleaner is to inhale air, then separate the dust in the air from the clean air, and exhaust the clean air to achieve the effect of dust collection.

However, some vacuum cleaners are not well separated, which will cause dust to adhere to the filter screen. In the long run, the filter screen will be blocked slowly, the air passing through will be less and less, and the suction will be greatly attenuated, so it will become more and more difficult to suck garbage. Only the screen can be changed very frequently.

1, sharp object

Generally speaking, domestic vacuum cleaners are still relatively expensive appliances. Sharp objects such as nails and glass will puncture the hose and cause the vacuum cleaner to leak. Please don't suck sharp objects.

2. Large particles

Generally, large particles can be easily swept up with a broom without using a vacuum cleaner. Of course, if it is round particles such as soybeans, mung beans and red beans, you can use a vacuum cleaner to suck them up. Other large particles are not easy to be sucked up when brushed, and it is easy to block the hose.
