Best Vacuum Cleaners By Suction in 2021 (Reviews, Suction Power Calculation, Factors & FAQs)

A vacuum does cleaning by sucking up dirt. A powerful suction will, therefore, mean deep and thorough cleaning of dirty surfaces. The efficiency and effectiveness of a vacuum can, therefore, be measured by the power of its suction. However, it may be difficult to know the best vacuum cleaners by suction since the strength of its motor is not always the indicator. Some factors will help you get a vacuum that suction well. This guide will elaborate on the factors one should consider when purchasing a vacuum based on its suction to get an excellent device. The top six cleaners will also be reviewed for a better understanding of what to look for in a vacuum.

What is Vacuum Cleaner By Suction?

A vacuum cleaner by suction is a type of vacuum cleaner that uses suction through the bottom of the machine to clean.

Before, people had to use a foot pedal to cycle through their different power modes. Now, this device has been replaced by a more efficient and faster-working motorized version.

Vacuum cleaners are often used for cleaning carpets, upholstery, and furniture. However, they also have other uses such as cleaning windows and car interiors. The device, which can also be called a “hoover” or a “vacuum”, is meant to clean up small bits of dust, hair, and other similar debris.

Vacuum cleaners thrive on several different types of motors: rotary or cyclonic; electric or pneumatic; stationary or portable. The two main types of those motors are axial-rotary and radial.

How To Calculate The Vacuum Cleaners Cleaning Ability by Suction or Power?

There is no single way to measure a vacuum’s ability but there are a few ways that can help you calculate the amount of suction for your vacuum.

Primary vacuum cleaning specifications include watts, amps, volts, suction power (or sealed water lift), horsepower, air wattage, and airflow.

Secondary specifications are set to include filtrations, cleaning tools (agitation), capacities, quality, noise levels, and features with cost.

  • To determine the number of air watts a model has, divide 0.117254 by the airflow and suction pressure (in inches of water). Which vacuum cleaner suctions the most? It is hard to tell without looking at the air watts. The more air watts, generally, the more suction power you will have.
  • When converting watts to amps, remember to always use the formula of watts/volts (always 120). For example, a 1400-watt motor would convert to 11.67 amps (1400/120=11.67).
  • The average rating for a vacuum cleaner is 10.5 amps for the power nozzle motor and 10 amps for a light bulb. There are two ratings that can be used to compare vacuum cleaners. The first is the motor rating, which measures how much power a vacuum cleaner can deliver, while the second is voltage on the plug in; this measures how much energy or amperage it takes to run a vacuum.
  • Another way to calculate the power of a vacuum cleaner is by measuring its suction power in cubic feet per minute (CFM). The power of a vacuum cleaner can be measured with respect to its ability to remove particles from the air. This includes dust, dirt, microbes and other airborne substances.

What To Consider When Searching For The Top Vacuum Cleaners By Suction

You cannot just go to the market and pick a vacuum just because you need one. Thorough research is needed to enable you to pick the right vacuum that best serves your needs. As much as you want a vacuum with powerful suction, you have to consider other features. How do you even know the power of the suction? Relax, we will explain to you the factors that you need to consider when looking for the best vacuum cleaners by suction. Check them below:

1. Motor Size

The size of the motor is measured in amps. Higher amps indicate a strong motor, which translates to powerful suction. The value of amp that is typically given by manufacturers is for a complete unit, which is not only for the motor but also LED lights or brush rolls. You should, therefore, know how much energy is used by other systems apart from the motor. From there you can calculate precisely the size of the motor. Sometimes it is indicated in the product description if you are purchasing online or in the manual. Get an excellent vacuum with powerful suction by buying one with a strong motor.

2. Number Of Motors

The vacuum can either have one or two motors. The vacuum with one motor uses it to power both the brush and vacuum while the one with two will run the vacuum while the other will run the brush. A two-motor vacuum is more powerful compared to a single one. Getting a two-motor vacuum with powerful suction will, therefore, result in superior cleaning.

3. Dirtbag Size

Having to keep on changing the dirtbag during cleaning is not only inconvenient but also disgusting. A sizeable dirtbag allows for continuous and effective cleaning. When the bag is full, the efficiency of the vacuum decreases. Get a vacuum with strong suction and an enlarged dirtbag. This ensures uninterrupted cleaning and efficiency of the vacuum. If you get a vacuum with a small bag, ensure you change it regularly to maintain the power of the suction even though it will be inconvenient.

4. Fill Location

The vacuum can have either an upright fill or a bottom fill. An upright fill leaves the trash to drop without any push. On the other hand, a bottom fill will force the vacuum to push the dirt up to create more space. This will strain the motor and thus decreasing the efficiency of the vacuum. Getting a vacuum with strong suction and upright fill will ensure the efficiency of the device is maintained at all times.

5. Airflow

The airflow is typically measured in cubic centimeters per minute. The ability of the vacuum to take in more air indicates a higher suction, which sucks the dirt way better. A HEPA filtration system is an added advantage; however, you should ensure the vacuum with this system has more watts than the one which does not. This is because the fiber filter is much tinier compared to the sponge ones.

6. Lift

The lift ability is checked through inches of water or the mercury lift. The water lift is particularly essential as it is the right way of checking the power of the suction. The higher the inches of water raised by the vacuum, the powerful the suction is. However, some vacuum has different systems of preventing overheating, and therefore measuring inches of water is impossible.

7. Construction Material

As much as you are interested in the appearance, of great importance should be durability, total weight, and comfort of maintenance. The durability will ensure you get value for your money. The material used may determine the weight of the vacuum. However, the manufacturer will always indicate the weight of the vacuum in the manual.

8. Ergonomics

The vacuum should be one that is designed well to allow easy maneuverability. The vacuums with ergonomics design are easy to use and less tiring. Get a vacuum that you do not get bored using by imagining the energy you have to summon to carry it around.

FAQS On Vacuum Cleaners By Suction

Below are some questions on getting a good vacuum cleaner by suction:

Q: Which Is Appropriate Suction Power For Vacuum Cleaners?

This depends on your needs. People’s preferences vary, but generally, small motors consume less energy, and the suction power is low. The bigger motors consume more energy, but it has powerful suction. A vacuum with moderate suction power will be appropriate if you only need it for your home or small office. If you have substantial cleaning needs then a vacuum with powerful suction will be best for you.

Q: Between Canisters And Uprights, Which One Has The Highest Suction Power?

In most cases, the canisters will have higher power suction compared to upright vacuums. The brush roll and head of the upright are closer to the bag with the sweep-and-vibrate mode of cleaning. The spinning brush roll helps the upright vacuum to collect much dirt without necessarily depending on the power of suction. The trash bin for the upright is much more significant which further makes it more convenient. It means as much as the canisters have more suction power, the upright vacuum can be effective because of its features.

Q: Are There Any Demerits Of Having A Vacuum With Powerful Suction?

Yes, there are disadvantages that come with a high suction-powered vacuum. Though the benefit may outweigh the con it is good to understand them as well. A powerful suction consumes much energy due to the large size of its motor. The power of the motor can make it noisy which can be a nuisance for those who want to concentrate even during vacuuming. The vacuum can also wear quickly due to increased temperature variation.

Q: Between Shop-Vacs And Backpack Vacuums, Which One Has High Suction Power?

The shop-vac is designed for commercial reasons while backpack vacuums are for home and small office use. Since the shop-vac is expected to do substantial cleaning, their suction power is high compared to the standard home vacuum. Many models will go up to 200 CFM and are used in both wet and dry floors. Even though backpack vacuum may have low suction power it does not mean it is not effective. The distance between the dirt and air intake is decreased making it efficient even with less suction power.

Final Word

No one really wants to invest in a vacuum that will still leave behind some dirt even after cleaning. This is probably the reason why you are looking for the best vacuum cleaners by suction. The power of the suction may be an indicator of how well the suction will do the cleaning. At times, however, it might be challenging to know how much suction you require based on your needs. For example, if you are looking for a commercial vacuum a shop-vac is recommended. ONSON has significant power suction and can, therefore, be used for commercial purposes or even in homes with high traffic.

As much as you want the vacuum with powerful suction, other features should not be overlooked. This is because the power of the suction may not necessarily indicate the efficiency and effectiveness of the vacuum. Upright vacuum, for instance, may have less suction power compared to canisters but still do a thorough cleaning. This is because of other features that compliment it. The suction power should also go hand in hand with the size of the motor. A vacuum suction with a small motor may make destabilize the device during cleaning.

Airflow is also something that should be considered when looking for a vacuum with powerful suction. The more the vacuum takes in the air the more its effectiveness. Check to ensure that the vacuum you buy has high airflow to ensure that the sucking of dirt is maximized, leaving the house conducive. If you go for a vacuum with a HEPA filter ensure that it has more watts as it will require more energy to push air in through the thin filters.

Never also underestimate the design of the vacuum since it determines how convenient and flexible it is. You will not want a powerful suction that will make you hate cleaning. Get something the will make you long for vacuuming your home. The ones with the ergonomic design are a perfect choice if you want a device that is easy to maneuver around. Holife Handheld Vacuum Cordless is a vacuum that you will not regret as it has powerful suction as well as ergonomically designed. The cleaning will, therefore, be more comfortable and less tiring.

Appearance should not blind you in choosing a vacuum with powerful suction. Check to ensure the material used is durable and makes the vacuum light. You will not want to get many people to help you carry the vacuum around the home. Suppose they are not there? Does it mean the cleaning will not be done? To avoid all these, get a portable vacuum with powerful suction. Bissell Zing Canister is a vacuum that is recommended because it has strong suction and is lightweight. Carefully go through the six vacuums reviewed based on their suction power. Hopefully, this guide will have done so much to make your work of choosing the right vacuum easier.
