Vacuum Cleaner History
Before the vacuum cleaner the simple task of
cleaning floors was not so simple. Area rugs would need to be taken outside,
hung from posts and beaten by a large wooden beating stick. Floors were
swept and the the debris was picked of by hand and then discarded. Today
when we vacuum our floors and carpets it usually takes about ten minutes,
but before 1880 cleaning carpets and floors was an all day task.
When vacuum cleaners were first invented they did not resemble the vacuum
cleaners of today. These first vacuum cleaners were large and heavy and were
usually transported from house to house by horse and carriage or were built
in the attics of larger homes with a suction system that was run throughout
the house. One of the first large vacuum cleaner units was invented by
British engineer called Herbert Booth. Herberts invention consisted of a
large box with a gas powdered motor that turned large fans to create
suction. Long bendable houses were fed through the doors and windows of a
house and debris was sucked into the gas powered unit outside. This first
vacuum cleaner was large and heavy and required it to be pulled by horses.
The vacuum cleaner as we know it today was invented in 1908 by James Murray
Spangler. This first version of the vacuum cleaner is a far cry from the
vacuum cleaners of today due to its simplicity and lack of power. Around
1920 William Hoover purchased the patent for this first vacuum cleaner from
James Spangler and the Hoover Vacuum Cleaner Company that we know today was
born. This first upright vacuum cleaner resembled a box on a stick with a
satin bag attached to catch debris. The actual vacuum cleaner itself was
made from a pillow case, an electric fan and a modified soap box. The beater
bar was added to the vacuum cleaner around 1926 which dramatically improved
the performance of the unit. This Hoover vacuum cleaner soon became know as
the Hoover Model 700 and was an instant hit. William Hoovers new patent was
soon to catch on and by 1950 nearly every household in America had its very
own Hoover vacuum cleaner.
The basic design and principle of the vacuum cleaner remained the same from
the 1950's through to the 1980's. In this 30 year span additional
modifications were made to the principal design such as vacuum cleaner self
propulsion and an exterior hose that could quickly attach to the vacuum
cleaner to clean baseboards and other hard to reach areas. In the 1980's
James Dyson invented the cyclonic bag less vacuum cleaner with increased
suction and the added savings of not needing a filter bag to catch the
debris. This cyclonic vacuum cleaner creates a vortex in the debris chamber
that sends the debris to the outside walls of the container and the air is
then pushed out through an exhaust vent.
In the late 1980's to early 1990's many vacuum companies started to
manufacturer hybrid vacuum cleaners that were built to perform different
vacuum duties. The back pack vacuum is one of these hybrids and consists of
a canister like vacuum cleaner that is worn on the back like a back pack
with a long hose that is used to clean walls ceilings and hard to reach
places. The wet dry vacuum cleaner was introduced not only pick up dry
debris but also liquids. This type of vacuum utilizes a motor and a float
valve that protects the motor against water contact and damage to the
electrical interior of the motor windings.
The latest and greatest innovation in vacuum cleaners is the closed system
vacuum cleaner. It is currently being designed in England and its primary
goal is to not suck air in and then exhaust it out but to circulate the air
in a closed chamber so that dust particles are not released into the air. By
keeping dust and other particles in the vacuum cleaner chamber the air in
the environment that is being cleaned is not polluted.
