Dialogue from the Construction Forum:
A: I have a cottage of 700 square meters. I want to make a central vacuum cleaner with my own hands, from sewer plastic pipes, to carry only the suction pipe from the socket to the socket... Your opinion, gentlemen?
B: There’s really enough subtleties here. Ordinary sewer pipes. How do you deal with the fact that all the dust absorbed into the socket through the hose will not reach the vacuum cleaner, but will be magnetized by static electricity to the inner surface of your pipe?
A: Well, we start with the fact that in the ordinary vacuum cleaner tube accumulates a lot of dust too, and when it accumulates a sufficient amount in the pipe, sooner or later it will go into the vacuum cleaner, and finally when using the above vacuum cleaner you can just regularly arrange cleaning the pipes, say just dry the water with anti-static through the longest pipe, and all. The dust allows it. Well, or just a hamster suitable in diameter in the pipe to push as a spark and the vacuum cleaner to turn on, just think of this will make him worse, although the "Animal Planets" showed the vacuum cleaner for the vacuum cleaners, as if nothing was alive afterwards.
