A vacuum
cleaner
,
commonly referred to
as a vacuum is a device that uses an air pump
to create a partial vacuum to suck up
dust and dirt, usually from floors. The dirt is
collected
by either a dust bag or a
cyclone for later disposal. Vacuum cleaners, which
are used in homes
as
well
an
in
industry,
exist
in
a
variety
of
sizes
and
models:
from
small
battery-operated
hand-held
devices
to
huge
stationary
industrial
appliances
that
can
handle
several
hundred
litters of dust before being emptied.
Technology
A vacuum's
suction is caused by a difference in air pressure.
An electric fan reduces the
pressure
inside the machine. Atmospheric pressure then
pushes the air through the carpet and
into the nozzle, and so the dust is
literally pushed into the bag.
Tests
have shown that vacuuming can kill 100% of young
fleas and 96% of adult fleas.
A
British
inventor
has
developed
a
new
cleaning
technology
known
as
Air
Recycling
Technology which instead of using a
vacuum uses an air stream to collect dust from the
carpet.
This technology was tested by
the Market Transformation Programmer (MTP) and
shown to
be
more
energy
efficient
than
the
vacuum
method.
Although
working
prototypes
exist
Air
Recycling Technology is not currently
used in any production cleaner.
Exhaust
filtration
Vacuums
by
their
nature
cause
dust
to
become
airborne,
by
exhausting
air
that
is
not
completely filtered. This can cause
health problems since the operator ends up
inhaling this
dust. There are several
methods manufacturers are using to solve this
problem. Some methods
may be combined
together in
a single vacuum.
Typically the filter is
positioned so
that the
incoming
air
passes
through
it
before
it
reaches
the
motor.
Typically,
the
filtered
air
then
passes through the motor for cooling
purposes.
History
The vacuum
cleaner evolved from the carpet sweeper via manual
vacuum cleaners. The
first manual
models, using bellows, came in the 1869s, and
first motorised models came in the
2
beginning of the
20
th
century.
Daniel Hess
Daniel Hess of
West Union, Lowe, USA invented a vacuum cleaner in
g it a
carpet sweeper instead of a
vacuum cleaner, his
machine did, in
fact, have a rotating brush
like a
traditional vacuum cleaner, which also possessed
an elaborate bellows mechanism on
top
of the body to generate suction of dust and dirt.
Hess received a patent (.29.077)
for
his invention of the vacuum cleaner on July 10,
1860.
Elves W. Mc Gaffe
The
first
manually-powered
cleaner
using
vacuum
principles
was
the
“
< br>Whirlwind,
”
invented in Chicago, USA in 1868 by
elves W. Mc Gaffe The machine was lightweight and
compact, but was difficult to operate
because of the need to turn a hand crank at the
same time
as pushing it across the
floor. Mc Gaffe enlisted the help of The American
Carpet Cleaning Co.
of Boston to market
it to the pubic. It was sold for
$$25. It is hard to determine how
successful
the Whirlwind was, as most
of them were sold
in
Chicago
and Boston,
and it is likely
that
many were lost in the Great
Chicago Fire of 1871. Only two are known to have
survived, one
of which can be found in
the Hoover Historical Center.
Mc
Gaffney was but one of many
19
th
-century inventors in
the United States and Europe
who
devised manual vacuum cleaners. He obtained a
patent (.91,145) on June 8,1869.
Melville Bissell
In 1876,
Melville Bissell of Grand Rapids, Michigan, USA
created a vacuum cleaner for
his wife,
Anna, to clean up sawdust in carpeting. Shortly
after, Bissell Carpet Sweepers were
born. After Melville died unexpectedly
in 1889, Anna took control of the company and was
one of the most powerful businesswomen
of the day.

John S. Thurman
On
November
14,1898,
John
S.
Thurman
of
St.
Louis,
Missouri,
USA.
Submitted
for
patent
(.634,042)a
“
pneumatic
carpet
renovator
”
.
It
was
issued
on
October3,
1899.
Thurman created a
gasoline powered carpet cleaner for the General
Compressed Air Company.
In a newspaper
advertisement from the St. Louis Dispatch, Thurman
offered his invention of
the horse
drawn (which went door to door) motorized cleaning
system in St. Louis. Louis. He
offered
cleaning
services
at
$$4
per
visit.
By
1906,
Thurman
was
offering
built-in
central
cleaning systems
that used compressed air, yet featured n dust
collection. Thurman
’
s
machine
is
sometimes
considered
the
first
vacuum
cleaner.
However,
the
dust
was
blown
into
a
receptacle rather than being sucked in,
an in the machine now used . In later patent
litigation,
Judge
Augustus
Hand
ruled
that
Thurman
“
does
not
appear
to
have
attempted
to
design
a
vacuum
cleaner or to have understood the process of
vacuum cleaning.
”
H. Cecil Booth
Hubert Cecil
Booth has the strongest claim to inventing the
motorized vacuum cleaner in
1901. As
Booth recalled decades later, in 1901 he attended
“
a demonstration of an
American
machine by its
inventor
”
at the Empire
Music Hall in London. The inventor is not named,
but
Booth
’
s
description of the machine conforms fairly closely
to Thurman
’
s design, as
modified
in later patents. Booth
watched a demonstration of the device which blew
dust off the chairs,
and thought it
would be much more useful to have one that sucked
dust. He tested the idea by
laying a
handkerchief on the seat of a restaurant chair,
putting his mouth to the handkerchief,
and then trying to suck up as much dust
as he could onto the handkerchief. Upon seeing the
dust and dirt collected on the
underside of the handkerchief he realized the idea
could work.
Booth
created
a
large
device,
driven
first
by
an
oil
engine,
and
later
by
an
electric
motor
electric.
Nicknamed
the
Billy
Booth's
petrol-powered,
horse-drawn
vacuum
cleaner
relied
upon
air
drawn
through
a
cloth
filter.
Gaining
the
royal
seal
of
approval,
Booth's motorized vacuum cleaner was
used to clean the carpets of Westminster Abbey
prior
to
Edward
VII
’
s
coronation
in
1901.
Booth
received
his
first
patents
on
February
18
and
August 30, 1901
David T.
Kenney
Nine patents granted to the New
Jersey, USA inventor David T. Kenney between 1903
and 1913 established the foundation for
the American vacuum cleaner industry. Membership
in the Vacuum Cleaner
Manufacturers
’
Associatio,
formed in 1919, was limited to licensees
under his patents.
Walter
Griffiths
In 1905
4
another manually operated cleaner,
patented by Walter Griffiths Manufacturer,
Birmingham,
England.
was portable, easy to
store, and powered by
domestic servant
he task of compressing a bellows-like contraption
to suck up dust through a
removable,
flexible pipe, to
which a variety of
shaped nozzles could
be attached. This
was
arguably the first
domestic vacuum-cleaning device to resemble the
modern vacuum cleaner.
Hermann
Bogenschild
German
immigrant
engineer
Hermann
Bogenschild
filed
a
patent
in
1906
for
a
mechanical
'dust
removing
apparatus.'
Emigrating
from
Berlin
to
Milwaukee
in
1892,
Bogenschild's device
was mounted on wheels for portability and its
motor was connected to a
hose and
filter system.
James Murray Spangler
In
1907,
James
Murray
Spangler,
a
janitor
Canton,
Ohio,
practical,
portable
vacuum
cleaner. Crucially, in addition to
suction that used an electric fan, a box, and one
of his wife's
pillowcases,
Spangler's
design
incorporated
a
rotating
brush
to
loosen
debris.
Unable
to
produce
the
design
himself
due
to
lack
of
funding,
he
sold
the
patent
in
1908
to
William
Henry
Hoover
who
had
Spangler's
machine
redesigned
with
a
steel
casing,
casters,
and
attachments. Subsequent innovations
included the first disposal filter bags in the
1920s and
the first upright vacuum
cleaner in 1926.
Hoover
Spangler patented his rotating-brush
design June 2, 1908, and eventually sold the idea
to
his cousin's husband, Hoover. He was
looking for a new product to sell, as the leather
goods
produced
by
his
'Hoover
Harness
and
Leather
Goods'
company
were
becoming
obsolete,
because of the invention of the
automobile. In the United States, Hoover remains
one of the
leading manufacturers of
household goods, including vacuum cleaners; and
Hoover became
very
wealthy
from
the
invention.
Indeed,
in
Britain
the
name
Hoover
became
synonymous
with
the
vacuum
cleaner
so
much
so
that
one
one's
carpets
Initially
called
'The
Electric Suction Sweeper Company',
their first vacuum was the 1908 Model O, which
sold for
$$60.
Nilfisk
In 1910, P.A. Frisker patented a vacuum
cleaner using a name based on the company’s
telegram
address
—
Nilfisk.
It
was
the
first
electric
vacuum
cleaner
in
Europe.
His
design
weighed
just
17.5 kg
and
could
be
operated
by
a
single
person.
The
company
Frisker
and
Nielsen
was
formed
just
a
few
years
before.
Today
the
Nilfisk
vacuums
are
delivered
by
Nilfisk-Advance.
