What is a Power Vacuum?
It is a trivial matter; vacuum cleaners are designed to absorb. A powerful high-pressure vacuum cleaner works best for removing dirt and dirt hidden from your carpets and tricky corners, between pieces of furniture, under your bed, and more. A vacuum cleaner with a low absorption capacity may remove the visible film of dust, but it does not remove the most challenging level of dirt beneath it. The higher the absorption capacity, the better your chances of removing heavy dirt from various areas. A powerful vacuum cleaner does not use a powerful engine. It’s all about design here. Let’s explain.
What does “high” Absorption mean?
Many people find it difficult to distinguish between low and high absorption units. If you want to test the absorption capacity of your vacuum cleaner quickly, try changing the filter to “carpet mode.” Open the unit and allow it to operate at maximum power. Try attaching the floor head to the wall. If you have a high absorption power device, it should always be attached to the wall without external support.
I’m sure many of you want specific details. That’s why we rely on realistic values. For example, to understand “gravity,” you need to know how it is measured. Traction can be supplied to the manufacturer’s specs in several ways, with various units: Watts, Amps, CFM (cubic feet per minute), or AW (Air Watts). Let’s see what each of them means.
Airflow (CFM)
It is one of the essential types of measurements and represents the force of airflow from the top to the bag (or barrel): the amount of air absorbed by the unit per minute, measured in cubic feet (ft3) / min). Although necessary, manufacturers do not always write this rate. More than 50% do not. If you are lucky and they offer this guide in the product features list, great! This feature considers both the strength of the car and the resistance of the exhaust system (filters, fans, bags, storms, and so on). The higher the CFM value, the more absorption capacity increases. Typical vacuum cleaners operate at a range of 50 to 100 CFMs.
Tip: CFM is usually measured without a connected pipe, rod, or other accessories; this is why you may end up having a much lower CFM than those listed in the specs.
Air Watts (AW)
Air Watts is another type of measurement of absorption capacity; this refers to the number of watts used by the machine to carry the air unit through the opening hole (usually the vacuum nose); this is my favorite measure because it is very much in line with the reality of what needs to be measured. If you are familiar with CFM and Watt Lift (also called closed absorption, measured in inches of the water column, if there is zero to open the mouth of the microphone), you can calculate the Air Watts size using the formula:
Air Watts = 0.117254 * Air Flow (CFM) * Water Supply (H2O inches)
Hoover once had an article on their website (gone now, I would have linked it) and said something like this: an excellent, straightforward person should have at least 100 AW and a canister, at least 220 AW. Why do you think canisters need more AW? Because they need to haul garbage through a pipe. Also, vacuum cleaners with sound filtering systems (i.e., HEPA) need an extra AW because they need to blow air through filter filters, much smaller than in the case of conventional sponge filters.
Tip: As you might guess, Air Watt is very different from Watt: 2 vacuum cleaners with the same engine (same number of watts) may have different efficiency (different number of Air Watts).
Water Lift (H2O inches)
Seal absorption testing is another good way to test the suction capacity of a vacuum cleaner. The unit is entirely closed and connected to a water-containing tube. The higher the water level, the more it absorbs it. However, conventional vacuum cleaners deal with this type of condition (some even have a way of reducing/shutting off energy to prevent overheating).
In the EU, the law prohibits (since 2014) the production of vacuum cleaners that use more than 1600W. Five years ago, EU officials estimated that they would apply the law to 500W by 2015, but things are still cool.
What is the Maximum Strength of a Vacuum Cleaner?
The absorption capacity can vary greatly, in many ways, externally and internally. While checking, if you use a filter outside the bag or without its HEPA filter, you will get high absorption levels. To the best of my knowledge, no one has ever tested the combined absorption capacity. IMO, Watts / Amps ratings are almost useless. The standard rate should be AW, but we will have to wait a long to reach that point.
How much Suction is enough?
The amount of absorption capacity required for a vacuum cleaner depends only on your needs. It’s like buying a car. Smaller moths eat less. Big engines are powerful and very fun. If you want a vacuum cleaner to keep your home or small office area clean and dust-free, a standard canister with a moderate amount of traction can be a good choice (you will save energy).
What’s wrong with having a Reliable Vacuum Cleaner?
Although a vacuum cleaner with high absorption has many advantages, it has its disadvantages as well. First, because it uses a potent engine, excessive use can lead to high power consumption. Otherwise, they can be very noisy and cause noise pollution. Finally, these units will be able to vary the high
Bottom line
In addition to the high absorption capacity, users should consider other factors such as ease of operation, control, and low noise levels when preparing to purchase a vacuum cleaner. Maneuverability is a quality that is often overlooked. That is, you do not have to have a powerful vacuum cleaner if you cannot use it to reach difficult areas.
