The First Vacuum Cleaner


Although considered a crecent invention, the Victorians had a machine which used bellows to suck up the dirt.
In 1901, a new railway-carriage cleaner was demonstrated at St. Pancras Station, London. It worked on the principle of blowing the dirt away but this proved unpopular and was not successful. Hubert Booth decided to reverse the process from blowing to sucking the dirt. To catch the dirt he used a cloth that let the air through but not the dirt; this acted like a filter and the dirt was easily thrown away.
Booth's first practical machine was so big that it had to be drawn by a horse. You can see it in the picture supplied by Google Images when you type in The First Vacuum Cleaner(It's like a red wagon with the words: 'Royal College? on the side.
To this day, all cylinder vacuum cleaners rely on Booth's principal. However, a Mr. Bissel in the United States, who was sick of sweeping up the straw in his china shop, made a commercial success out of vacuum cleaners by combining it with a sweeper for home use.

I'll bet you have on at home!
