WARNING to all of you using a vacuum cleaner. NEVER use a vacuum cleaner indoors with the windows shut. The vacuum cleaner will suck in all oxygen in the room with dangerous dire effects to all there.
This happened to me the other day. I was at home alone, except for the cat, and I decided to vacuum clean the carpet in the front room. The windows in the house were shut. After a while I felt a little light-headed, then I felt rather faint. I must have lost consciousness and fell to the ground.
Unfortunately, the vacuum cleaner was still on and it tried to suck me and the cat within it.
I slowly eased myself forward an inch at a time until I reached the electric socket in the wall and I unplugged the vacuum cleaner.
I opened the window to let in some air in the room as I was gasping for breath.
I then reversed the vacuum cleaner controls from suck to blow and switched it on. The cat shot out of the nozzle at speed and flew out of the window upwards, past the tree in our front garden, and into the open window of our neighbor's bathroom, and landed into our neighbor's lap as she was lying there in a warm bubble bath.
I'll leave the rest of the scenario to your imagination as I stood there watching at her window and asking for our cat back!
