Evolution of Vacuum Cleaners
We take vacuum cleaners for granted but think of all that dust the appliance clears and how much ef-fort would go into cleaning if you were to do it manually. The contraption has been evolving over the years, from the earliest machines that came into existence in the 17th century to today. The best vacu-um cleaners are those that are ideal for all surfaces and conditions, and have an intuitive interface and smart technologies.
Early years - manual operation
Although attempts were made in the 1600s to come up with a device/machine to clean rugs, the first sign of a vacuum cleaner was in 1860 when Iowa man Daniel Hess launched an appliance that had brushes to gather dust and bellows for shifting dust to a container. This device was basically a carpet cleaner and needed manual operation. Later, there was a similar appliance built on the same idea launched by a Chicago man called Ives McGaffey. The machine which was called the Whirlwind had a belt unit to make cleaning and transferring dust into a container. This was invented in 1868. This method was easier but was still bulky.
When the machine became a vacuum cleaner officially!
Through the years, more minute changes came about to the vacuum cleaner, but the first motorised appliance finally made its appearance in 1901. An Englishman called Hubert Booth and an American called David T Kenney independently introduced a vacuum cleaner that had suction power. The credit to coining the word 'vacuum cleaner' is also given to Booth. In this early version, the device helps in creating a tight seal in contact with the floor so that the resulting vacuum helped in pushing or sucking the dust.
Portability and ease of use
Still, in the early years, all the devices continued to be bulky and not so simple to be lugged around. It was in 1905 that Walter Griffiths ushered in a machine that was a portable vacuum. It still need the user to foot pump, but was much easier to use. A year later, James Kirby introduced a system wherein a water filter was used to stop dust from escaping from the canister. Yet another year later, in 1907, James Spangler introduced a vacuum that ran on electricity and kicked up dust, and then transfer it into a canister without any manual help. William Henry Hoover bough the patent for the same from Spangler and 1908, and thus brought about the vacuum revolution!
