How does a container vacuum cleaner work?
They work on the principle of a spiral: vortex flows are twisted inside the devices, they separate dust, which, under significant centrifugal force, “sticks” to the walls of the container. After cleaning the container, it is enough to shake it out and wash it with water.
Why does a vacuum cleaner lose suction power?
The most common reason that the vacuum cleaner began to suck badly is an overfilled dust container. So that you understand, if a bag or flask for collecting garbage and dust is eighty percent full, then the vacuum cleaner's thrust is much worse. And over time it falls off completely.
