Understanding Vacuum Cleaner Specifications

Understanding a sizable number of confusing specifications is among the most difficult areas of choosing a brand new vacuum cleaner. Foremost and first, consumers need vacuum cleaners that provide the most effective cleaning ability. And many customers generally equate cleaning ability with "suction" or "power".

Cleaning ability isn't simply about suction and power, although these characteristics are important components of vacuum cleaner efficiency. With a bit of education and info, you are going to be ready to sort through the numbers and also better comprehend exactly what the specs hostile and which ones are crucial to you.

Regrettably, there's no individual rating which indicates cleaning ability. Nevertheless, there are a variety of main specs, which when clearly understood, enable customers to make educated choices concerning which vacuum cleaner has the most desirable cleaning ability.

These main specifications include watts, amps, volts, drinking water lift (or sealed suction), air watts, horsepower, and also airflow.

There are as well a selection of additional, secondary specifications which influence cleaning potential that we will also analyze. These consist of filtration, cleaning equipment (agitation), noise, quality, capacity, price and features.

To be able to make sense of everything we first have to recognize the fundamentals of the way a vacuum cleaner works.

Most vacuum cleaners work grounded on air moving from the opening at the washing head or maybe tool, through the vacuum cleaner as well as the bag as well as filtration system then out the fumes port. This airflow is produced through the vacuum motor, which additionally could be described as the suction engine.

The vacuum motor comprises of electric components placed on numerous fans or a fan. Whenever the followers spin, a partial vacuum is produced and the strain inside the vacuum cleaner drops below the ambient (or existing) air pressure in the space. Because air pressure is more outside the vacuum cleaner than interior, air rushes through the vacuum cleaner.

Thus, it's not hard to notice that the vacuum motor will be the center of a vacuum cleaner. All things considered, the better the motor, the higher the pressure differential and consequently the more airflow and suction, right? And it's because of this that the majority of the specifications you see regarding cleaning skill connect either indirectly or directly to the motor.

But here is where it becomes tricky. Specifications for elements like the motor don't always relate to the functionality of the whole vacuum cleaner, and thus are just a portion of the story.

Let us check out the main specifications one by one:


The input energy of the vacuum engine is calculated in watts. Even though this specification does not take into account the effectiveness of the engine, the quantity of followers or maybe the general vacuum cleaner layout, motor power level is a legitimate method to assess and examine the strength of the engine.

While the perfect comparison is motor input energy in watts of Product A compared to engine type in energy in watts of Product B, several makers don't supply motor input power specifications in the type of watts but instead rate entire vacuum cleaner in amps. This could help make it difficult to evaluate across brands.

Nevertheless, you are able to change amps to watts by the system, amps x 120 (volts) = watts. Or perhaps alternatively, you are able to change watts to amps by the system, watts/volts (always 120) = amps. For instance, a 1400 watt motor changes to 11.67 amps (1400/120=11.67).

Comparing models rated in amps with those rated in watts isn't an actual comparison because companies that're using watt ratings typically rate the engine just while amperage ratings make use of the entire power use of the vacuum cleaner like the engine within the electrical power nozzle (the motor-driven revolving comb cleansing head), etc, light bulb.

What this means is that a strength Team (a canister vacuum cleaner with a strength nozzle) with a specification of twelve amps are very similar to another Power Team with a 1200 watt motor which changes to just ten amps.

This's because the energy nozzle motor consumes 1.5 amps, the light bulb makes use of more amperage so on. Thus, in case we subtract the amperage utilized by the energy nozzle motor from our twelve amp machine, we think of 10.5 amps for light bulb along with the motor. In this particular example, the 2 motors both have scores of extremely close to ten amps, and consequently, equivalent engine input power.

Thus, it's ideal to either compare motor input energy in watts of equally devices and in case you've to compare a machine ranked in watts with one ranked in amps, attempt getting the amperage rating on the engine only rather than the whole vacuum cleaner. You are able to then transform this to watts and also have a significant comparison.


A really widespread vacuum cleaner specification is amps. The amperage rating indicates the optimum amount of electric current utilized by all the vacuum cleaner's power components when operating. The greatest customer of electric current is going to be the vacuum engine, although amperage rating features the electric components, like the vacuum motor, the electrical power nozzle engine, the light bulb, etc.

The optimum amp "draw," (the amount of amps the vacuum cleaner uses when running) permitted for every machine which plugs right into a standard home outlet is twelve. Consequently, in case you notice amperage ratings above twelve, read the small print, as they're not accurate amperage specifications though some other company developed "performance rating" created to produce the feeling of an effective vacuum cleaner.

Although amperage refers to electric use without strength or maybe cleaning capability per se, it may be utilized to evaluate the input power of a single vacuum cleaner to yet another. This's because while input strength is calculated in watts, amps are changed into watts by multiplying by volts. Since volts are regular at 120, amps stand for a valid comparison of engine type in energy.

Once again, as stated above, when making the comparison, try getting the amp rating on the engine only rather than the whole device.

Therefore, amp ratings provide us a way of looking at the input power of a vacuum engine as well as the vacuum cleaner in its entirety and are a significant specification for comparison purposes. However, they're just section of the story. All things considered, simply because a motor or maybe vacuum cleaner consumes much more energy, that doesn't allow it to be a much better cleaner.

The amps specification also doesn't take into consideration just how effective the motor is, along with other design components, like whether the engine has a single or maybe 2 fans (2 is not always better than one) as well as the entire effectiveness of the vacuum cleaner design.


In the United States, regular household current runs at 120 volts at the meter. Voltage within a house is often called "110" and this's because there might be voltage drops through the home wiring. But never to be concerned, devices are created to work within a selection of voltages from 110 to 120.

For the purposes of knowledge vacuum cleaner specifications the single thing about voltage we actually have to learn will be the system, amps x volts = watts & alternatively, watts/volts = amps. When performing these computations utilize 120 volts for U.S. gadgets.

Water Lift (Sealed Suction)

The sealed suction of a vacuum cleaner is calculated in inches of h2o lift. This rating is used once the engine is completely sealed, so the phrase describes the number of in the motor will vertically lift a 1" column of h2o.

Water lift is what provides a vacuum cleaner the capability to acquire or maybe "lift" clutter from the floor surface area, while airflow subsequently removes it with the dust bin. Vacuum cleaners with even more inches of water lift has a simpler time getting sand and various other heavier soils from flooring and carpet.

Water lift is also a measure of a vacuum cleaner's capacity to deal with resistance within the vacuum cleaner. This's particularly significant in HEPA or maybe high filtration vacuum cleaners with much more resistance because of the extra filters that the environment must pass through.

An excellent water lift rating in addition suggests that a vacuum cleaner can keep performing at amounts that are high as the dust bag or maybe box fills as well as the screens "load" or perhaps steadily load up with good particulate and also be increasingly more reluctant to air passing through.

The drinking water lift of a vacuum cleaner is yet another helpful sign of effectiveness in it's a way of evaluating the suction of 1 engine to another as well as, typically speaking, the greater number of water lift up the better.


This's a score which was used mainly for advertising purposes and also had little or maybe no relation to vacuum cleaner functionality within the real world. Fortunately, it's been mostly done away with as a vacuum cleaner specification.

Frequently described as "Peak Horsepower" these ratings had been acquired by eliminating the followers from the vacuum engine and exposing it with the highest load likely prior to the motor burned out. Next, an intricate system was put on to think of a Peak Horsepower rating. Once again, this particular specification is meaningless in regards to analyzing the cleaning capability of a vacuum cleaner.

Air flow Watts

As we've mentioned, typical vacuum power specifications like watts and amps measure the vacuum cleaner's type in energy. Central vacuum makers, in addition to various other vacuum cleaner companies, are utilizing air watts specification to make an attempt to rate the vacuum cleaner's paper rather compared to input power. Air watts are estimated using the system, (Air Flow (in CFM) x Vacuum (in inches of h2o lift))/8.5 = Air Watts.

Once more, there's a little question regarding whether this's a helpful specification or simply a fresh rating to further confuse customers and make comparisons hard. All things considered, whenever you do the computations, an air watt comes to 0.9983 watt or even nearly the just like a regular watt.

It's important not to mistake atmosphere watts with airflow, the most crucial specification of all.


Airflow is definitely the most crucial specification regarding identifying the cleaning capability of a vacuum cleaner. Measured in cubic foot per second (CFM), it's the power of the airflow across a surface area which picks up the grime and moves it to the dust bag or perhaps container. Thus, the greater airflow, the happier the cleaning capability of the vacuum cleaner.

Airflow is a superb specification since it takes into account both potential of the vacuum engine, and that generates suction, in addition to the opposition on the bag and filtration process that this particular air should pass through.

Airflow is often assessed through the vacuum cleaner with no hose or maybe attachments connected. Due to this particular, you can find many elements which can impact real airflow, such as turbulence in the hose as well as wands, limitations on airflow where cleaning tool meets some other surface or the floor, increased resistance as a result of the bag filling with soil and cleansing loading.

Comparing Primary Specifications

In terms of these main specifications, there are 3 components that are helpful in comparing vacuum cleaning solutions.

The very first comparison is watts to watts engine type in energy. Ideally, the devices currently being compared will all have engine type in energy specified in watts for a simple, direct comparison. If one machine is ranked in amps as well as the other in watts, a transformation of the amps specification to watts makes comparability possible but is "apples to apples" just when the motor amps alone are utilized for this comparison.

As stated in the amps aisle above, if the one specification offered is the amps for the entire machine, a comparison may really be produced though it won't be an immediate one.

If both devices are ranked just in amps, a comparison may be created of the power use of every device having an assumption when these're equal or close, the motors are very similar in input power. This's because the engine is going to be the biggest customer of the ranked amperage.

The next comparison is going to be drinking water lift (sealed suction). This's a great specification to examine just how well the vacuum cleaner is going to perform as the bag fills as well as the screens load, and is particularly pertinent when selecting high filtration or maybe HEPA filtration vacuum cleaning solutions. Additionally, it offers some notion of just how vacuum cleaners compare in regards to getting heavier soils like sand, grit so on.

The 3rd thing of comparison is airflow. This's the most crucial specification in the world when selecting a vacuum cleaner because airflow is the thing that moves the grime from surfaces on the dust bag or perhaps container. In a nutshell, airflow is perfect specification which demonstrates cleaning ability.

And so, now with airflow ranked in CFM as well as liquid lift ranked in inches, what kinds of numbers woud you want to be searching for? On canister vacuum products (with and with no power heads) airflow of hundred CFM or even more and water lift of ninety inches or higher is recommended.

Upright vacuum cleaners are available in a multitude of configurations, but you can find 2 standard designs. The first will be the "Direct Air" or maybe "Dirty Air" design in which the dirt passes through the engine before any filtration en route on the dust bag. Dirty air uprights are merely ranked in amps.

The second fundamental design is one which has a by pass motor where unfiltered air doesn't proceed through the motor. In uprights with this particular design, just filtered or maybe completely clean space air passes through the engine to be able to cool it. By-pass uprights often provide airflow but not drinking water lift specs along with a high performing upright can provide sixty CFM or even better.

There's no demand for water lift scores on both kinds of uprights, because there's very small distance of the air and earth to travel. CFM ratings don't need to be as large as canisters for exactly the same purpose.

Many uprights won't provide airflow scores at all and will only rate the engine in terminology of amps. As we've learned, which one measures the electrical use of the engine, which is not a degree of cleaning ability. Nevertheless, when evaluating different vacuum cleaners of this particular kind, amp scores are much better compared to nothing.

When you select a vacuum cleaner with exceptional water and airflow lift specifications, you're best on your way to a computer with great cleaning ability.

Secondary Specifications

We've analyzed the main specifications which impact cleaning ability. But you can find also secondary specifications which must be considered prior to making a final choice. These consist of filtration, cleaning equipment (agitation), noise, quality, capacity, price and features.


Filtration is vitally important in regards to cleaning ability because HEPA or any other innovative filtration enhances the opposition within the vacuum cleaner. Thus, it's simpler for a vacuum cleaner with regular filtration to achieve substantial airflow ratings. In reality, the task of coping with increased resistance is among the factors that HEPA filtration vacuum cleaning solutions are able to cost more.

The dust bag is part of the filtration process along with a significant element influencing airflow. Many new components, rather than conventional newspaper, are now being utilized to produce dust bags to be able to remember the fine dirt and harmful small specks while still permitting atmosphere to run as easily as you can.

The surface part of the dust bag is as well a consideration because the far more surface region the bag has, the more quickly the air is going to flow through it. This means better cleaning capability while the bag fills. This's a great reason to select full sized vacuum products versus moderate or maybe simple ones.

Cleaning Tools (Agitation)

The main cleaning application has to be properly selected because while airflow is the thing that transports those soils on the dust bag, agitation is the thing that dislodges dirt from carpeting, other surfaces and flooring.

Thus, explore the kind of cleaning methods that make sense for the home of yours. In case you've plenty of carpet or maybe difficult soils including pet hair, pick an upright or maybe a power group with an electric power nozzle. If you've furniture that's tough to get under, make sure your vacuum cleaner has a sufficiently low profile cleaning nozzle to achieve these places so on.

If you've a vacuum cleaner with all of the airflow in the planet but an insufficient cleaning tool, benefits will likely be much less than optimum.


The capability of your respective vacuum cleaner has a job in regards to keeping high levels of cleansing ability. As we saw above, the bigger the particles bag, the happier the airflow, and consequently, cleaning ability. Other things being equal, a full sized vacuum cleaner is going to offer better cleaning ability, particularly as the dust bag or maybe container fills.


The quality of your respective vacuum cleaner is also essential. You are able to have exceptional specifications inside a poorly constructed vacuum cleaner which lasts just a few years, when compared with really good quality products which will deliver great cleaning performance and can last a long time as well as years.

Quality could be partly based on the length of the guarantee along with the kind of materials used, the caliber of the healthy and finish, just how a lot of the housings are, just how small the seals, just how close the tolerances so on. Generally, mass-market, low priced products aren't created for long-term use.


Noise is also a major concern. Some vacuum cleaners are usually very noisy they are almost unbearable to work with. A high quality vacuum cleaner will frequently operate at levels which are very comfy and will enable you to hear the phone or maybe doorbell ring rather easily.

The quantity of sound a vacuum can make while working is ranked in decibels (dB). In order to provide you with plenty of idea, a chat at home is ranked at 50dB, a garbage disposal at eighty dB along with a motorcycle or maybe lawnmower at hundred dB. Extremely quiet vacuum cleaners are able to run at decibel amounts in the mid sixties while cleaners in the 70 77 dB range are still really quiet in comparison to the vacuum cleaner you were raised with. Features Then, you have to think about whether the vacuum cleaner you are contemplating has all or the majority of the functions that you have to have for pleasant and effective cleaning.

Think of your cleaning situation and make sure the vacuum cleaner you pick provides you with everything to make the task of vacuuming as simple as they can. Does it offer a cord rewind, variable speed controls, on board equipment storage, height adaptable wands, a sufficient cleaning radius, the correct resources for your flooring like a gentle brush for your slate entry flooring so on. Cost And, survive but not least, you want a vacuum cleaner which presents the best price. As with anything, better quality generally costs somewhat more, but is usually worthwhile in the end.
