Its a miracle! I plug the chord in and this marvelous machine sucks the dust off the floor, along with a small toy, a beetle, 2 spiders and their web and a button I have been searching for. No-one else in this house seems to be able to do this. 'Tom, can you do that thing with the machine that makes that funny high pitched sound?' is the pathetic request from 'Her Ladyship'.
It's called a vacuum cleaner and the act of using it is called vacuuming.
My sister brought a young man home to meet my parents many years ago. My father said her appeared to have the intelligence of a vacuum cleaner. The young man must have had a retractable chord for I saw no sign of a 3 pin plug protruding from his rear.
