Household Vacuums -
Suggestions
Types of
Household Vacuums: We will divide our
recommendations (suggestions) on Household Vacuums below into two sections based
upon either canister or upright types of vacuums and then provide our
recommendations (with unassailable logic!) for a specific brand(s) in each
section.![[Image] of vacuuming](images/pict0.jpg)
Preamble: Most people use either an upright vacuum or a canister
vacuum as the main vacuum in their house. The main vacuum, then, is the vacuum
primarily responsible for maintaining the "health" of the house. To keep the
house healthy, this main vacuum needs to do two things well: (1) it needs to
efficiently remove pollutants/allergens from the carpet, upholstery, floors,
etc. and (2) it needs to effectively control emissions so that these same
pollutants are not spewed back into the air.
This requires a considerable degree of precise engineering and meticulous
construction and very few manufacturers are interested in producing machines to
these standards. It is a lamentable fact, therefore, that only a handful of
manufacturers make vacuums in which the main vacuum housings are airtight.
If the housings are not airtight, millions of microscopic contaminants per
minute can be forced out through these housing apertures as the machine is
vacuuming. Thus, a sealed system is needed to control emissions
- a HEPA filter installed on a vacuum that is leaking dirt elsewhere through the
housings only filters the rest of the dirt that reaches the filter - only a very
small percentage, therefore, of the total emissions of pollutants is arrested. The
simple reality is that a better vacuum will clean better, filter better, last
longer and require less maintenance than a "cheaper" vacuum.
It is, therefore, a "better" purchase.
Canister Vacuums: We believe that, in most instances, a canister
vacuum is a better choice as a main vacuum than an upright vacuum. Our reasons
are simple:
- In most instances a good canister vacuum uses a
larger (heavier), more powerful motor than a good upright vacuum
- The extra weight of the canister motor becomes
less important because the canister vacuum is riding on the ground; whereas with
an upright vacuum the weight of everything on the machine is significant since
the entire vacuum is constantly being pushed and pulled
- A canister vacuum absolutely offers more
versatility than an upright vacuum
- The main carpet tool - whether a revolving brush
or a traditional rug nozzle - is lower than the body on an upright
- This allows getting under low furniture and beds
much more readily
- The hose and the wand(s) are already coupled
together and instantly allow longer reach for dusting ceilings, corners and
edges
- All the cleaning accessories are immediately in
reach on the vacuum - not always the case on upright vacuums
- There is an accessory for every job
- Rug tool and/or power brush
- An upright vacuum is not normally equipped with
a rug tool - the upright vacuum itself is the rug tool
- Rug tools are extremely handy for corners and
tight spots, as well as for getting under low furniture
- Bare floor tool
- Upright vacuums are largely unsuitable for bare
floor use. Some have switches that allow the brush to stop rotating when used
on a bare floor surface. This improves bare floor performance; however, it
falls far short of a bare floor brush. On some uprights, it is possible to
attach a bare floor brush to the end of extension wands connected to the hose;
however, this arrangement can be awkward when being used. Only one upright -
Lindhaus - is actually designed to be used with an optional bare floor brush
mounted directly to the main vacuum body - a very nice design feature
- Dusting tool
- Upholstery/drapery tool
- Crevice tool
- Extension wands
- Cars can be readily cleaned with a canister
vacuum
- Stairs - a problem area - can be readily cleaned
with an appropriate canister
With all the above noted,
we will cheerfully sell you an upright vacuum if that is your desire; although,
we find that most upright owners then regularly buy a small canister for its
convenience and versatility for the types of cleaning chores present in the
average home or office.
Canister Vacuum Recommendation: While we believe that, as in most
aspects of life, there are alternative choices, we absolutely recommend the
Miele Canister Vacuum over all others. If you
ever had the privilege to take a tour through a Miele factory you would need
little more than the few hours spent in the factory to enable you to understand
that Miele excels in everything they do.
Miele is a 100 year-old German appliance
manufacturer that produces the finest washing machines, dishwashers, stoves,
sanitizing equipment, vacuums (and other appliances) that can be found anywhere
in the world. Miele is awesome - very few manufacturers think like they
do - they are perfection-driven.
- Miele makes their own motors on most of their
canister vacuums
- The best American motors do not, ultimately,
satisfy their standards for quality
- Miele makes their own vacuum housings and
components
- Total control of the manufacturing process
results in extremely high levels of precision in fitted parts
- Precisely engineered and manufactured components
fit together perfectly and work better and last longer without breakage
- A Miele canister vacuum will likely last 15 - 20
years
- Most vacuums today last 1 - 5 years
- Miele canister vacuum housings are airtight and
a Miele canister with a HEPA filter assures true control of polluting emissions
99.97% to .3 microns - .3 microns is bacteria size! The Miele vacuum
with the HEPA filter in place rates today at a Class 12 rating (only step behind
a critical-filtration industrial vacuum for use in a Nuclear Bio-Hazardous Waste
facility rated to a Class 15) and is actually rated at HEPA/ULPA.
A Miele canister vacuum uses 3 - 4 independent,
full 360-degree swiveling caster wheels with soft,
non-marring rubber wheels
A late model Miele canister vacuum hose swivels
freely 360 degrees for complete ease-of-use
The exhaust air on a Miele exits on top of the
vacuum
This prevents millions of bacteria and
pollutants already at floor level from being stirred up and airborne as happens
with ground level exhaust orifices as found on many vacuums
It allows the vacuum to stand on end for ease of
vacuuming stairs, etc. as the exhaust air is not shut off as is the case with
other vacuums
The disposable vacuum bag automatically seals
itself as it is slid out from the vacuum
No pollutants puffing back into oneself's
face as the bag is removed
Miele intelligently markets their vacuums in
such a way that you decide which optional accessories you wish - not the
manufacturer (all standard cleaning accessories are always included with every
Miele). You tailor the vacuum to your own personal needs and uses
You have to see or use a Miele vacuum to
understand how smooth and powerful it is as it operates, and to experience the
almost effortless way it glides around the room
1-year guarantee on everything (except belts)
and 5-year motor guarantee
There are other choices. Royal makes an
all-metal tank that is a very fine vacuum, and Lindhaus makes an excellent
canister vacuum. In an intermediate price point, Samsung has a Quiet Storm
canister that is a good choice. However, Miele is Miele - the best!

Upright Vacuum
Recommendations: We recommend three upright vacuums, in order, as
meeting our standards for high quality: Lindhaus,
Sebo and Royal all-metal.
Lindhaus:
Lindhaus is an 30-year old Italian manufacturer of motors and equipment
for international use. They make the finest twin-motor upright vacuum available
for residential use.
- Two motors mean that each motor performs its own
task - good division of labor!
- The main motor has two fans for optimum air flow
and suction and provides the cleaning power to enable thorough (deep) cleaning
of surfaces of any type
- The second motor spins the revolving brush
- The Lindhaus engineers are motor experts
- A Lindhaus motor undergoes many more steps in
the manufacturing and balancing process than even the best American motors
- Without getting too technical, the more windings
in the motor and the better it is balanced the less there is vibration and heat
- the killer of motors - and , therefore, the longer it will last
- A Lindhaus motor will likely outlast most
competitor's motors by 3 - 5 times!
- It is likely that Lindhaus motors - and the
entire vacuum - will last 20 years
- All Lindhaus upright vacuums use bypass
sytems so that the vacuum motor is protected from coming into contact with
what is being vacuumed
- The Lindhaus engineers are plastics experts
- All the plastics in the vacuum are carefully
selected to be the best possible material for that specific application
- The vacuum housings and components are extremely
durable and long-lived
- A Lindhaus powerhead (remember, the vacuum has
two motors1, and the revolving brush resides
in an actual powerhead connected to the main vacuum body) has a brush that spins
at a constant 5,000 rpm
- Most revolving brushes spin around 2,000 rpm to
3,000 rpm
- It becomes progressively harder to spin a brush
at faster speeds because the brush must be perfectly balanced to achieve such
high brush speeds without excessive vibration
- Vibration both causes brush assemblies to
disintegrate and also causes the housing in which the brush sits to wear out
rapidly
- Vibration also cause the drive belt in a vacuum
to "shimmy" while the unit is operating - considerably reducing belt life
- Lindhaus powerheads are intelligently designed
with the dirt intake directly in the center of the brush area
- Most uprights today have an intake all the way
on one end of the brush area
- It is considerably more efficient to get the
dirt to a central intake than it is to try to get it all the way down to one end
- Lindhaus powerheads use cogged belts; not,
rubber belts
- Cogged belts are not made of rubber; rather,
they are made of a fiberglass-reinforced material much like an automotive timing
belt. Essentially, they do not stretch
- Rubber belts stretch and constantly must be
replaced to keep the brush spinning properly
- Vacuum industry suggestion for belt change
intervals on most vacuums - once every 3 - 4 months!
- Cogged belts do not slip as do rubber belts -
they have "teeth" that grab cog gears on both the motor spindle and the
revolving brush
- Cog belts - as distinct from rubber belts - only
need replacement when they finally snap
- Lindhaus brushes, belts and motors are so well
"tuned" to each other that there is almost no belt vibration. Thus, the belts
do not fatigue and prematurely wear out
- A Lindhaus powerhead is designed with a sensor
system that instantly turns off the brush motor - thus, halting the action of
the brush - if the brush becomes jammed. Thus, the belts (and, the motor or
revolving brush) never become unduly stressed
- The Lindhaus powerhead has a full height
adjustment mechanism
- Most upright vacuums today have no height
adjustment mechanism (cheaper to make them that way). This "no-adjustment" is
euphemistically called "universal adjustment"
- An upright vacuum depends heavily upon the
revolving brush action. To be able to properly adjust the brush to different
types and heights of carpet is important - if not critical
- Lindhaus powerheads employ a sensor system
connected to both a red and a green light on the powerhead housing. When the
powerhead is properly adjusted the green light is on. If the head is adjusted
down too close to any given carpet, the red light goes on. If the head is then
not re-adjusted properly, the powerhead will turn off! This protects the belt,
brush & powerhead motor
- The Lindhaus vacuum housing is precisely
engineered to be airtight. Thus, no pollutants can escape as with regular
vacuums
- Most Lindhaus upright vacuums are designed to
accept Hepa filters; however, Lindhaus vacuums are equipped with 3M Filtrete
filters that have been specifically engineered by the 3M people to fit
the
Lindhaus and to optimize airflow and filtration
- The Hepa filter provides absolute filtration of
99.97% to .3 microns
- The 3M Filtrete filter provides filtration of
98% to .3 microns
- There are tools-on-board (TOB) with most
Lindhaus upright vacuums
- This facilitates cleaning corners, edges, sofas
& chairs, tabletops, etc.
- Additional tools (cleaning accessories) and
longer hoses are available, as well
- On most Lindhaus upright vacuums the powerhead
is removable by simply pushing one button, and a dedicated bare floor tool can
be installed in its place
- This makes Lindhaus the only upright of which we
are aware that converts efficiently to a bare floor vacuum
- Lindhaus has an
excellent dry carpet-cleaning powerhead that can be attached in place of the
regular powerhead
- This enables fast, easy, effective dry-cleaning
of any carpet anytime
- On most Lindhaus upright vacuums the top handle
can be removed by pushing one button
- Since the powerhead also is removable, a
Lindhaus vacuum instantly converts into a canister-style machine
- An optional backpak harness is available that
further enables the Lindhaus to be used as a backpak vacuum. Very nice,
flexible feature!
- A Lindhaus vacuum lies completely flat to get
under beds and furniture
- A Lindhaus has a long (35-ft) cord so that once
plugged in to a wall socket it can continue to be used in a wide area before it
needs to be plugged in to another outlet
- 1-year guarantee on vacuum proper, 2-year
guarantee on motors, 3-year guarantee on belt
1 Lindhaus
makes a great single-motor upright called the Activa; however, most of our
Lindhaus business is still twin-motor uprights

Sebo: Sebo is a German manufacturer of upright vacuums and
carpet cleaning equipment. We consider a Sebo upright to be a "rung down the
ladder" from a Lindhaus - only because it is a single-motor upright.
However, for a single-motor upright it is a great vacuum!
Many of the same design features found on Lindhaus upright vacuums are found on
the Sebo upright vacuum:
- Precisely balanced motor
- Brush speed of 5,000 rpm
- Cogged belt with a safety shut-off sensor system
- Centralized dirt intake in the revolving brush
area
- Full height adjustment
- Sebo has a unique, sensor-driven,
fully-automatic height adjustment system that is very nice. The vacuum
perfectly adjusts itself to every level of carpet or flooring
- Large, S-class filtration filter (99.97% @ .3
microns) for complete allergen control
- Sealed housing compartments - no emissions!
- Bypass motor-protective system
- Unbelievably quiet at 66 decibels
- Commercial-grade 40-ft long cord
- High-quality construction materials
- On-board tools (TOB) with a great design feature
whereby the hose instantly repositions itself automatically back onto the vacuum
after it has been used - no bending or groping, etc. to reattach the hose
- Additional accessories - including a bare floor
brush! - available
- Likely 20-year life expectancy
- 3 year guarantee on unit; 1 year on labor
Sebo also has a revolving brush with a
slickly-designed feature that makes it instantly removable by pushing one
button. This makes cleaning the brush of hair, thread, etc. extremely easy. A
Sebo upright is an excellent upright vacuum that will completely satisfy the
most discriminating user!

Royal all-metal: Royal Manufacturing Company is the oldest
manufacturer of vacuum cleaners in the world - since 1905.
They
make a traditional upright vacuum - without tools-on-board (TOB) - that
is all-metal (aluminum). It uses an efficient, ball-bearing, convergent
revolving brush with the same central dirt intake design as does the Lindhaus.
For those who prefer a traditional style upright
vacuum, Royal has no peer. It has a full height adjustment mechanism, a long
cord, a metal toggle switch, non-marring wide wheels and filtration available
down to .1 micron at 98%. It is far and away our largest selling upright vacuum
for commercial use: Liz Claiborne has been our biggest, single corporate
customer; the State of NJ buys Royal uprights under contract for schools,
hospitals, government agencies, etc.; and, contract cleaners, hotels, bowling
alleys and many others use this fine equipment.

Suction motors, amps, watts,
horsepower, suction and cleaning effectiveness: We should add a note
on vacuum cleaner design, motors, suction and airflow as there is much confusion
as to horsepower, amperage, watts, cleaning amp effectiveness, etc.
The key to a vacuum cleaner's performance is the design of the machine.
This includes the motor. Better motors are designed to perform better and last
longer while using less electricity than inferior quality motors. A motor needs
to be "tuned" to the application to which it is being put. It does no good
to design a motor with high airflow and low suction to remove sludge from a
production pit - it simply won't budge it - the sludge weighs too much.
Conversely, if one is cleaning flour from a bare surface high suction is less
important (the flour is lightweight) than good airflow. Design is the key
element!
- Amperage
- Amperage ratings - as they are bandied about
today - are largely meaningless
- The better a motor is designed, the less
amperage it will use
- There is a "break-even" point to this statement
- if one motor is 2 amps and the
other
is 10 amps - the 10 amp motor will absolutely be more powerful
- If two, equivalent-amp motors are rated side by
side for performance and one motor has one fan and the other motor has two fans
- the motor with two fans will move more air. Thus, the number of fans in a
motor can become important
- Horsepower
- Horsepower is another misused, misunderstood
rating
- Many manufacturers unscrupulously rate their
motors on peak horsepower rather than on true VCMA (Vacuum Cleaner
Manufacturers Association) ratings
- A motor rated on peak horsepower has been rated
with the motor out of the vacuum and in a bench vise. It is literally fed more
and more electricity until it "explodes" and the last, final "peak" rating is
used. Peak horsepower ratings are totally meaningless
- Watts
- Ratings of watts is somewhat like amperage
ratings - it is not going to tell you too much beyond the fact that a motor in a
given machine should have at least a base level amperage or wattage rating -
otherwise, it will probably be too small
- Suction
- Suction is a universal format and is measured in
waterlift in inches (mbar in Europe)
- Suction is rated as to how far up a one-inch
diameter tube a vacuum (motor) is capable of lifting a column of water. Thus,
80 inches of waterlift means the vacuum (motor) was able to lift the water
column up 80 inches
- In the residential, portable vacuum category 80
inches of waterlift is good and anything near 100 inches is awesome. A simple,
waterlift reference scale would be:
- 25-year old Hoover-type Convertible upright when
new - about 12 inches
- 25-year old Electrolux tank-type vacuum when new
- about 60 inches
- A Lindhaus upright vacuum - about 80 inches
- A Miele White Pearl canister vacuum - about 90"
- 100"
- Airflow is the amount of air - measured in cubic
feet per minute (CFM) that a vacuum (motor) can move
- CFM is very important to a vacuum's ability to
remove dirt from any surface - especially carpet - and to effectively carry it
back to the dirt compartment. 80 cfm and above is good airflow
- Better vacuum manufacturers will usually provide
CFM and waterlift ratings for their equipment. These ratings are much more
important than the amperage ratings, etc. CFM is closely tied to waterlift -
i.e., the two are "intertwined"
It is easy to see from the above that design is
the critical factor in considering vacuum cleaning performance. A motor must
provide adequate, balanced amounts of CFM and waterlift to enable the vacuum to
do its job properly so that different, varying types of materials may be
vacuumed up. And, as importantly, the vacuum must have a totally sealed dirt
path from the nozzle all the way back to the dirt compartment so that no
cleaning power is lost. And, don't forget about filtration and containment of
particles!
