Why are good vacuums so expensive

Why are good vacuums so expensive

The dust removal working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed to drive the fan impeller to rotate, so that the air is discharged at a high speed, and the air in the vacuuming part at the front end of the fan continuously replenishes the air in the fan, resulting in an instantaneous vacuum inside the vacuum cleaner, which forms a negative pressure with the outside atmospheric pressure. The pressure difference, under the action of this pressure difference, sucks in the dust-laden air. To discharge clean air, the greater the negative pressure difference, the greater the air volume, and the greater the vacuuming capacity.

For a vacuum cleaner, the motor is its "heart", which can provide the source power for the vacuum cleaner. It also determines the suction power of the product when it is working, and also determines the cleaning effect. Under normal circumstances, products with high suction power have good dust removal effects, so a good motor is very important. However, a good motor will increase the manufacturing cost of the product, and it is generally used in high-end vacuum cleaner products. Therefore, most of these high-end vacuum cleaners are not cheap.

What are the downsides of cheap vacuum cleaners

1. The noise is loud, and the suction cannot meet the requirements for a long time, and it is especially noisy. As soon as it is turned on, there is no other sound in the whole family, except for the unbearable noise of the vacuum cleaner "rumble" machine running.
2. Poor battery life. Expensive vacuum cleaners can generally be used for several days or even a week, while cheap vacuum cleaners can only be used for about an hour, and some have to be charged in a few hours. Vacuum cleaners with poor battery life are particularly unsuitable for housing areas. Large family use.
3. Low suction, cheap vacuum cleaners cannot take care of every corner of the house, so the dead corners cannot be removed, and manual cleaning is required. Secondly, it is particularly easy to be entangled by hair and cause the machine to malfunction.
