Hand Held Vacuum Cleaners Reviews
Have you ever wondered how
hand held vacuum cleaners or for
that matter any vacuum cleaner works? When you suck soda via a straw, you are
utilizing the simplest of all suction mechanisms. Sucking the liquid up causes a
pressure drop between the bottom of the straw and the top of the straw. With
higher fluid pressure at the bottom than at the top, the liquid is pushed up to
your mouth.
Although the execution is a bit more
complicated, this is the same basic principle at work in a vacuum cleaner. A
vacuum cleaner - whether hand held or not - is actually made up of only six main
components:
- An intake port, which may contain a diversity of
cleaning accessories
- A motor powered by electricity
- A fan
- A vesicular bag
- An exhaust port
- A housing that contains all the various components
When you turn the vacuum cleaner on, the following
happens:
- The electric circuit operates the motor, which is
attached to the fan with angled blades just like a propeller of an airplane.
- As the blades of the fan turn, they force air
forth, toward the exhaust port.
- When air are driven forward, the air pressure is
increasing in front of the fan and decreasing behind it.
There are many brands of
hand held vacuum cleaners and we are going to
take a closer look at three of the best of them:
Bissell 33A1 Pet Hair Eraser
The Bissell Pet Hair Eraser gets both positive and
negative testimonies for picking up pet hair. People who have used it say it's
great, while one professional reviewer says removing pet hair is this unit's
only drawback. The Pet Hair Eraser is not cordless, but has a 16-foot power
cord, which means you don't have to be concerned about a battery running down.
The 4-pound Bissell hand held vacuum cleaner is easy
to use and does a great job picking up particles from carpets as well as hard
surfaces, and testimonies say it's also good at getting into corners and
around edges. It is delivered with two nozzles and a washable HEPA filter that
cuts down on emissions.
Black & Decker PHV1800 18 Volt Pivot Vac
This hand held vacuum cleaner is the top cordless vac
in testing, and users say it works well at picking up both fine and coarse
particles. They also say it's powerful and easy to use, and has enough battery
capacity to clean a set of stairs or the interior of a car.
The Pivot Vac folds in half for storage and has a
ten-position pivoting nozzle in addition to an integrated extension nozzle and
a three-stage filter. It comes with an upholstery brush, a wall-mountable
charging base as well as a small crevice tool. Although it is a bit expensive,
the two-year warranty is actually twice the industry standard.
Shark Cordless Hand Vac SV736
The Shark SV736 beats the Black and Decker described
above in one comparative test. While it doesn't get the same number of top
ratings as the Pivot Vac, users say the detachable motorized brush does a
great job on carpets and on digging up hair from pets. In addition to the
motorized brush, the Shark handheld vacuum comes with a detachable filter that
can be washed, a crevice tool as well as a LED charging indicator.
