Vacuum Configurations

Thursday, January 8th, 2009

Vacuum Configurations

Vacuum cleaners are devices that use an air pump to
create a partial vacuum to suck up dirt and dust,
normally from carpeted floors. Most homes that have
carpet floors have a vacuum for cleaning. The dirt
that is pulled up from the carpet is collected by
a filtering system or even a cyclone for later
disposal.

There are several type of configurations possible
for vacuum cleaners.

Upright
Upright vacuums have the pump mounted directly above
the suction intake, with the bag mounted directly on
the handle, which will rise to waist height or so.
The upright type designs normally employ mechanical
beaters which often rotate brushes, to help disturb
dust enough to be vacuumed up. These beaters are
normally driven by a belt that is attached to the
vacuum motor.

Canister
Also known as cylinder vacuums, the canister type
designs have the motor and bag in a seperate canister
unit that connects to the vacuum head by a flexible
hose. Even though upright units have been tested
as being more effective, the lighter and more
maneuverable heads of the canister models are quite
popular. Some models have power heads, which contain
the same type of mechanical beaters found it upright
units, although they are driven by a seperate electric
motor.

Wet vacs/dry vacs
These types a specialized form of the canister
vacuum and they can be used to clean up wet or liquid
spills as well. They will commonly accomodate both
wet and dry soilage, with some being equipped with
a switch or exhaust port that reverses the flow of
air. This is a very useful function for everything
from clearing clogged hoses to blowing dust into a
corner for easy collecting.

Back pack vac
These types of vacuums are commonly used for
commercial cleaning, as they allow you to move about
quickly and efficiently in a large area. They are
basically canister vacuum cleaners, except for the
fact that straps are used to carry the canister
on your back.

Built in or central
These types of vacuum cleaners will move the suction
motor and bag to a central location in the building
and provide vacuum inlets at strategic places
throughout the entire building. You only need to
carry the hose and pickup head from room to room,
while the hose is normally 25 foot long and allows
a large range of movement without changing vacuum
inlets.

The plastic piping will connect vacuum inlets to
the central unit. The vacuum can either be unpowered
or have beaters that are operated by an electric
motor or an air driven motor. The bag in the
central vacuum system is normally so big that
emptying it or changing needs to be done less as
often, sometimes only once a year.

The Essential Vacuum Cleaner

Saturday, January 3rd, 2009

The Essential Vacuum Cleaner

The vacuum cleaner is a truly amazing piece of
equipment, as it would be very hard to cope without
one. There are many people out there who prefer
domestic vacuum cleaners for carpeted floors in
their home.

No matter how you look at it, the vacuum cleaner is
an ingenious piece of equipment. It has an air
pump that creates a partial vacuum to suck up the
dust and dirt, which it collects by a filtering
system or a cyclone to dispose of later.

Vacuum cleaner types
Based on their configurations, there are many types
of vacuum cleans. The following are some of the
most known types of vacuum cleaners.

Bagless
Bagless vacuum cleaners, as the name implies, don’t
use bags. They collect the dust in a compartment
which you can quickly and easily empty. This will
save you from the headache of dealing with messy
and frustrating vacuum bags.

Upright
Upright vacuum cleaners have the pump mounted
directly above the suction intake, with the bag
mounted on the handle that will normally rise to
waist height. The designs of upright vacuum cleaners
will normally employ mechanical beaters, which
are often rotating brushes, to help dust that has
yet to settle be vacuumed up. An attached belt to
the vacuum motor will drive these beaters.

Canister types
Canister vacuum cleaners have the motor and the
bag in a separate cylinder unit that is connected
to the vacuum head by a long flexible hose. Even
though the upright units have been tested as being
more effective, the lighter and more maneuverable
heads of the canister are also popular. There are
some canister models on the market that feature
power heads which contain the same type of beaters
as found with upright units, even though those
types of beaters are driven by a seperate electric
motor.

Backpack
Backpack vacuums are a great tool for commercial
type cleaning. Backpack vacuums will allow you to
move around rapidly in a large area. It is
basically a canister vacuum cleaner, except for the
fact that the straps are used to carry the canister
unit on your back.

Central vacuum
A central or built in vacuum cleaner has the suction
motor and bag based in a central location of the
building, providing vacuum inlets at strategic
places throughout the building. This way, you only
need to carry the hose and pickup head from room
to room. The hose is normally 25 foot long,
allowing a large range of movement without having
to change vacuum inlets.

A plastic pipe will connect the vacuum outlets to
the central unit. The head of the vacuum may
either by un-powered or have beaters that are operated
by an air driven or electric motor. The dirt bags
in central systems are so big that you only need
to change or empty them once or twice a year.

Robotic
Robot type vacuum cleaners will move around your
home, cleaning as they wish. They are compact and
powered by batteries.

Hand held
Hand held vacuum cleaners are very small and powered
by either batteries or electricity, and very popular
with cleaning up small spills.

Wet or dry vacs
Wet or dry vacuum systems can be used to clean up
both wet and dry spills and dirt.

Vacuums are very helpful with protecting yourself
and your family from dust particles. They are also
helpful for those who suffer from allergies that
result from dirt and dust. Before you buy a vacuum
cleaner, you should always read some reviews and
find out other information to ensure that the vacuum
cleaner you buy will meet your needs.

How Vacuum Cleaners Work

Friday, December 26th, 2008

How Vacuum Cleaners Work

Even though it may appear to be a very complicated
machine, the conventional vacuum cleaner is actually
made up of six essential components: intake port,
exhaust port, electric motor, fan, porous bag, and
a housing that stores all of the other components.

When you plug the vacuum cleaner into the outlet and
turn it on, the following happens:
1. First of all, the electric current will
operate the motor, which is attached to the fan,
which resembles an airplane propeller.
2. As the blades begin to turn, they will
force the air upwards, towards the exhaust port.
3. When the air particles are driven forwards,
the density of the particles will increase in front
of the fan and therefore decrease behind it.

The pressure drop that occurs behind the fan is
similar to the pressure drop when you take a drink
through a straw. The pressure level in the area
that is behind the fan will drop below the pressure
level that is outside of the vacuum cleaner.

This will create a suction inside of the vacuum
cleaner. The ambient air will push itself into the
vacuum cleaner through the intake port because the
air pressure that is inside of the vacuum cleaner
is much lower than the pressure on the outside.

Picking the dirt up
The stream of air that the vacuum generates is just
like a stream of water. The air particles that move
will rub against any loose dust or debris and if
it is light enough, the friction will carry the
material around the inside of the vacuum cleaner.

As the dirt continues on to the exhaust port, it
will pass through the cleaner bag. They tiny holes
in the vacuum cleaner bag are large enough to let
the air pass through, although too small for the
dust particles to fit through. Therefore, when
the air current gets into the bag, the dirt and
debris will be collected there.

You can stick the bag anywhere along the path
between the intake tube and the exhaust port, just
as long as the air current passes through.

Suction
The power of a vacuum cleaner’s suction will depend
on several factors. The suction can be stronger
or weaker depending on:
1. Fan power – In order to generate a
strong suction, the motor needs to turn at a good
speed.
2. Air passageway – When a lot of debris
builds up in the bag, the air will face a greater
level of resistance on the way out. Each particle
of air will move slowly due to the increase in
drag. This is the reason why a vacuum cleaner
works much better once you’ve replaced the bag
than when you have been using it for a while.
3. Size of the intake port – With the
speed of the vacuum fan being constant, the amount
of air that passes through the vacuum cleaner per
second is also constant.

How To Vacuum

Thursday, December 25th, 2008

How To Vacuum

To maintain the look, feel, and appearance of your
carpet you’ll need to vacuum on a regular basis. If
you are new to vacuuming, you’ll find the tips below
to help you when it comes to keeping your home clean:

1. Before you start, you should always inspect
the area. Pick up any objects that could cause
your vacuum cleaner to clog up. The smaller objects
are fine, just as long as they will pass through the
vacuum.

2. You should check the vacuum bag to ensure
that is isn’t full already. If it is full, you
should go ahead and change it. A full bag isn’t
going to suck up much dirt, as the power will be
greatly reduced due to the bag taking up a great
deal of storage and limiting the suction.

3. You should always vacuum forwards instead
of going backwards. Going forward will get the
job done quicker and you won’t wear your cord out
near as fast. When going backwards, you also run
the risk of running back over your cord, which is
something you don’t want to do.

4. Be sure that you overlap your strokes
to ensure that you get out all of the dirt and the
residue. You don’t want to miss any of the carpet,
which is why it is important that you overlap your
strokes.

5. You should change your vacuuming
direction on occasion to reduce any type of matting
in your carpet. You can change direction without
any problems. Doing this every time you make a
sweep on the carpet or every other time you vacuum
will be good.

6. On corners, use a damp cloth or a
crevice tool attachment that hooks up to your
vacuum cleaner. This will ensure that you get the
corners and tight areas good, and they don’t
stand out from the rest of the carpet.

7. You can get rid of dust particles and
dirt by waving a vacuum wand under your bed. Doing
so on occasion will ensure that your bedroom
stays clean, and smells clean as well.

For kitty litter on carpets or floors, you should
use a lightweight vacuum cleaner. To get deep
into the fibers of the carpet, you should try
an upright vacuum cleaner with a power brush. Kitty
litter can be a pain in the neck if it gets
crushed in the pile or embedded, which is why
you should get it out as quick as you can.

Give some thought to purchasing a vacuum cleaner
with a rotating brush or combination beater and
brush bar, which will loosen up the dirt in the
carpet and then suck it out. This will beat the
dirt from the fibers and even embedded dirt, which
will leave your carpet clean and smelling great.

Whenever you vacuum, you should always be on the
lookout for straw, thread, and string as it can
trap debris in the vacuum hose and result in a
clog. These types of hazards are also bad for the
agitators as well, as they can clog up the suction
as well, or get tangled up in the agitators and
cause more problems.

If you have pets, you should sprinkle some baking
soda on the carpet before you vacuum. Let it sit
for a little while, then vacuum. The baking soda
is a lot cheaper than carpet fresheners and it
does the same thing – only better.

Vacuuming is very easy to do, and it’s something
that should be done on a regular basis. You don’t
have to be an expert to vacuum, all you have to
do is make an effort. Your carpet will look good
all the time, and your house will stay smelling
great – which is reason enough to grab the vacuum
and take a trip through the house with it.

Get Out More Dirt

Sunday, December 21st, 2008

Get Out More Dirt

The most important part of carpet maintenance is
removing and disposing of accumulated dry soil. The
removal of dry soil will improve the air quality
indoors, extend carpet life, and help to maintain
the carpet. Keeping regular maintenance on your
carpet is one thing, although being sure you have
the right equipment on the job is another.

The Green Label
For vacuum cleaners, the CRI (Carpet and Rug Institute)
has developed a Green Label testing program. The
CRI developed the performance protocol with the
goal of protecting indoor quality, keeping all
surfaces as clean as possible, and all without
putting dust back into the air.

The Green Label program helps to identify vacuum
cleaners that meet three different types of criteria:
1. Removing soil.
2. Keeping dust out of the air by
containing it within the filtration bag and the
machine itself.
3. It doesn’t damage the carpet and helps
to keep the appearance looking good.

The tests for determining the certification of a
vacuum cleaner were developed by carpet and vacuum
experts and reviewed by scientists with experience
in maintenance and the quality of indoor air.

Soil removal
The soil removal protocol will require that the
vacuum cleaner remove a specified quantity of soil
from the test carpet in four passes.

Dust containment
The protocol for dust containment will dictate the
total amount of dust particles that are released
into the surrounding air by the action of the
brush rolls, through the filtration bag, and any
leaks that come from the vacuum system. with this
test, the vacuum cleaner can’t release more than
100 micrograms of dust particles per cubic meter
of air.

Carpet retention
The testing protocol for appearance retention will
require that the vacuum cleaner not adversely
affect the appearance of the carpet, based on
a year of normal usage.

If a vacuum cleaner meets all three of the above
requirements, the manufacturer may then display
the official CRI Green Label on it’s brand of
vacuum cleaner. The CRI tests canister and upright
vacuums, wide area vacuums, and even walk behind
types as well.

Matching machines
Looking for that important Green Label is the first
step to providing longer carpet life and cleaner
air for your home or office. The next step is
selecting the proper vacuum cleaner for a specific
area. You can think of vacuum cleaners like
screwdrivers, as you wouldn’t want to use a Phillips
head screwdriver to remove a flathead screw.

In the bigger, more open areas, a wide are vacuum
cleaner or sweeper can produce excellent results,
as well as an increase in productivity. The
average 14 inch upright vacuum can clean at a rate
of 3,000 square feet per hour, while the average
walk behind can clean at a rate of 40,000 square
feet per hour, and also lift the pile of carpet in
high traffic areas where the carpet fibers are
subject to crushing and matting.

The two motor upright vacuum cleaner is an excellent
choice in areas such as executive offices, lobbies,
conference rooms, and break areas. A two motor
upright can provide grooming of the fibers in the
carpet and removal of the dry soil. Most uprights
with two motor setups will also have a removable
hose and on board accessories for cleaning other
areas as well, such as vents and chairs.

Along with the type of area, you should also give
some thought to the needs of the operator. If
you are a manager, you should look for vacuums
with ergonomic features, especially if the vacuum
will be used for long periods of time.

If it isn’t ergonomically designed, it could result
in injury to the operator. At the very least, the
cleaning operator might want to avoid using
vacuum cleaners that could result in injury.

Buyers Guide

Saturday, December 13th, 2008

Buyers Guide

Deep cleaning vacuums
The typical features with these types of vacuums
include rotating brushes that agitate the carpet
pile and loosen the dirt for better clean. There
are some models that offer a handy automatic tool
conversion button or switch that you can push or
flip as you move from carpet to hardwood floor.

Hand held vacuums
Hand held vacuums are light weight, can be corded
or cordless, and you can even mount most of them
on the wall if you prefer. The performance of the
cordless models will depend on the charge of the
battery, as the battery power drops, so will the
suction power.

The two types of hand held vacuums include straight
suction and suction with a power brush. If you
are considering a hand held vacuum cleaner, you
should consider its primary purpose, if you plan
to use it on a regular basis or occasionally on
smaller jobs.

Broom vacuums
Stick or broom vacuums are great for smaller type
apartments, quick clean ups in the kitchen, or
a family room. The benefit of a broom vacuum is
the light weight. If you have trouble pushing
your heavier upright around, the broom vacuum
may come as a relief. You’ll also have the option
of getting your vacuum corded or cordless.

They usually weight 2 – 7 lbs. and allow you to
easily store them in the closet, as they take up a
minimum amount of space. For quick disposal of
the dirt and debris, most models are also bagless
as well.

Wet or Dry vacuums
The wet/dry vacuum combination may very well be the
most versatile vacuum cleaner on the market today,
with numerous attachments and functions it is a
very handy machine to have around your home. The
canister types can vary from the smaller 6 gallon
sizes to the larger 22 gallon sizes.

The HP ranges as well, from 2 to 10 HP. You should
always try to match the size of the unit to the
size of the job and frequency of use.

Upright vacuums
One of the most popular features of an upright
vacuum cleaner is the bagless system. In addition
to the increased performance, there is no need
to purchase any bags. Emptying the canister can
be a little dusty, although it’s still better than
messing with bags.

Most upright models come with a standard set of
attachments that may even include an upholstery
tool, a crevice tool, and even an extension wand.
A retractable cord and manual or automatic pile
adjustments are other common features. A HEPA
filter is another common and popular feature found
with most upright vacuums.

Canister vacuums
Canister vacuum cleaners normally include retractable
cords. Considering the fact that most cords are
around 25 foot in length, this feature will prevent
you from having to drag the cord around and
possibly damage furniture. A push of a button or
a slight tug on the cord will retract it into the
canister of the vacuum.

The nozzle can be one of two types, nozzle or
power nozzle. To get your carpet as clean as
possible, it is recommended that you use the power
nozzle, which will agitate the carpet and loosen
up the dirt for deeper cleaning.

Another feature worth looking for is a suction
control switch, as this allows you to adjust the
flow of air for cleaning delicate material such
as upholstery and drapery.

When choosing your vacuum cleaner, you should always
choose the one you like best. The best vacuum for
the job is the one you should choose, as things
will work out much better that way.

Belts And Performance

Thursday, December 11th, 2008

Belts And Performance

The belts for vacuum cleaners can come in many styles
and hundreds of different sizes. Normally, vacuums
use a belt to drive an agitation device, which
is also known as a brush roller. With very few
exceptions, most vacuums will use either a flat
belt, round belt, or a geared style belt.

The type of belt that your vacuum uses is very
important, not only for durability, but performance
as well. The condition and type of belt your
vacuum uses will have a lot of impact on the systems
ability to clean carpet. The proper use of
agitation is almost 70% of the cleaning ability of
a vacuum cleaner.

Suction is also very important. The suction is
what pulls the dirt that is removed from the carpet
into the collection area of the vacuum. The
suction, or airflow, is the key when cleaning
hard surfaces or when using attachments. Without
suction, a vacuum cleaner could only bring more
dirt to the surface of carpet. Even though both
agitation and suction are important with vacuuming,
the agitation is what actually cleans them.

Almost all manufacturers use brush rollers that
are made of wood, metal, or even plastic that
is driven by a suction or brush motor through
the use of three different kinds of belts – round,
geared, or flat.

The round belts are the earliest type as they
were easy to produce and easy to engineer. The
round style, unfortunately, is normally run in
the same space as vacuumed dirt. What this means,
is that almost all of the dirt, staples, and
hair you vacuum up will pass around the belt;
cutting, nicking, or even scratching it along the
way.

Vacuum cleaner belts have to stretch quite a long
way, placing even more stress on the roller and
the motor bearings. The round belt is still
common, and used even today.

The flat style of belts are most often run in a
circular fashion as well, unlike the twisted
route the round belt takes to deliver the
performance in the proper direction.

The style allow manufacturers to run the belt off
of one side of the brush roller, instead of the
center where all of the dirt is. This is truly a
great innovation, as you can eliminate premature
failure due to the soil and dirt in the belt path.

The latest belt design is considered to be the
best in the industry. Even though there are many
variations out there, the geared belt is the
most efficient means to drive a brush. The
geared belt is also known as a positive brush system
because the energy of the brush motor is
transmitted directly to the brush.

Both the brush and the motor are locked by
fixed teeth to each other through a cogged belt
without tension. The resulting direct connection
results in higher cleaning efficiency because
the brush can be driven at a faster speed
regardless of the age of the belt.

The flat style can stretch as they become warm,
which will cause them to lose tension. When
you use your vacuum, the belt is always going to
stretch. Believe it or not, it will lose it’s
tension the moment you put it up to rest in the
closet.

There is however, one real drawback to geared
belts – the cost of the vacuum. Geared belts
are normally used on two motor vacuums. Not
only does this require a separate suction and
brush motor, but it also requires electronic
sensory systems to tell you when something is
wrong with the brush.

Bagged Versus Bagless

Wednesday, December 10th, 2008

Bagged Versus Bagless

As with most things in life, there is really nothing
free. The two most claimed advantages to bagless
vacuum cleaners were lower operating costs and
better performance. As far as the cost issues go,
all vacuums must filter the exhausting air they use
to carry the dirt into the collection area, as they
would otherwise simply pick the dirt up from the
floor and spit it right back out.

Whether you have a bagless HEPA filter, a pre-filter,
or disposable bags, they all need to be changed at
some point. With the average life of a vacuum
cleaner, you can expect to spend the same on either
collection system for filters, but if you value your
time, you can expect to spend quite a bit more on
a bagless system.

To keep your bagless vacuum cleaner operating at
peak levels, you’ll need to empty the dirt container
when it is full and perform regular maintenance on
the filter. The type of filter the vacuum uses will
determine just how much service will be required,
although most use a pleated HEPA filter.

Cleaning
Even though the claim of better airflow performance
with bagless vacuums is true in a sense, over the
life of the vacuum you’ll get the same, or maybe
even better performance from a bagged vacuum cleaner
system.

With bagged vacuum cleaners, the performance will
start at 100% with each new bag then slowly drop
as the bag starts to fill. Just how quickly the
performance drops depends on how well the bag is
constructed. With the average vacuum and the average
bag, you may replace the bag every 3 – 4 weeks
with 90% of performance the first week, 70% in
weeks 2 and 3, then 50% of less in the fourth week.

The short cycle will insure that you get a 100%
peak cleaning every 3 or 4 weeks from the vacuum
cleaner. The filtered cyclonic machines have
filters that are designed to last 6 months, 12
months, and even up to 18 months before they need
to be replaced.

Pets
If you have dogs or cats, whether you see it or
not, almost all domestic animals shed their fur
on a regular basis throughout their lives. Pet
owners often wonder as well, which vacuum is the
best to remove pet hair.

For pretty much the same reasons that fur sticks
to the carpet, it will also stick to your bagless
vacuum’s pleated filter cartridge. The fur will
reduce the performance of airflow, and is also a
pain in the neck to clean off the filter.

Over time, the fiber that makes up the filter can
retain odor from pets, even if you clean the
filter well. If your filter requires replacing
only once a year, you could end up with a vacuum
that spits odors that will stink up your house
pretty bad.

Bagged up
Those vacuums that use bags will often provide
for neat disposal of a full bag. There are some
brands such as BOSCH that actually engineer bag
disposal into the system. With BOSCH canister
vacuums, the replacement of bags is a single
dust free step. The new mega filt bags have a
built in closure system that upon removal,
will slide shut and trap the dirt and debris
inside of the bag, making removal quick and easy.

Still, there are many people out there who love
bagless machines. Bagless vacuums will continue
at a slow place to gain market share, and people
will continue to buy them. For many, a bagless
vacuum can be the right vacuum to have.

Bags are the technology of the past, while bagless
is the technology of the future. There are many
reasons as to why you should go bagless. For
the vacuums of tomorrow, cylinder and bagless
is the key.

What Is The Best Type Of Vacuum Cleaner

Wednesday, December 10th, 2008

Choosing the best type if vacuum cleaner can be really difficult. If you are planning to really clean your home, car, camper, or job site, you may be amazed by the many types of vacuum cleaners. There are several
out there, with each one offering you an array of special uses and features all at lots of different prices..

To keep from being disappointed when you buy your vacuum cleaner, the ideal thing to do is make a list of your price range and budget and what you need your vacuum to do. Then, you can start shopping around and narrow your list down until you find the vacuum that is perfect for your needs.

There are several vacuum machines on the market today (Rainbow Vaccum Cleaners, Hoover Vacuum Cleaners, etc.), and you’ll have no problems finding one that will complete your tasks with ease and durability.

Not surprisingly, vacuums are available in several different colors, sizes, and prices. Basically, there are two main types of vacuum cleaners out there – wet and dry vacs, and there are even companies out there that have found ways to combine both features. You can choose from cordless,
handheld, and even bagless models. If you are feeling really lazy, you can even purchase a robotic vacuum cleaner that will vacuum your entire house for you while you watch — how cool is that?

Normally, vacuum cleaners are made of either durable heavy duty plastic or aluminum. They range in colors, from green to red to silver and white to blue. Models vary, and you can choose from upright, canister, stick, hand
held, and shop vac models.

There are some specialty vacuum cleaners that are specifically designed to help get difficult debris and dirt out from under your car seat and others that are made to help you clean your beautiful hardwood floors. Other features can include extra detachable extension gadgets and tools, retractable power cords, a HEPA (clean air) filter, and an easy to reach power switch. There are even models out there that will pick up crazy stuff like nails and even glasses of water.

There are lots of companies to choose from as several companies out there produce vacuum cleaners, including Oreck, Simplicity, Dyson, Hoover, Bosch,
Sanyo, Bissell, Eureka, and Kirby. If you are looking for a vacuum cleaner, you have a huge selection of discounted and refurbished vacuums out
there waiting for you.
