How To Buy Vacuum Cleaners With Strong Suction

When buying a vacuum cleaner, many customers are only interested in the appearance and price without looking closely at the parameters of the machine. This is the biggest mistake because the specifications will reflect the strength and weaknesses of the device. If ignored, you may buy the wrong vacuum cleaner that does not match your requirements. This article will show you how to evaluate the suction power of the Best vacuum in the world through their indicators.

Why is strong suction necessary for a vacuum cleaner?

The motor is the heart of the vacuum cleaner as it generates suction. And the suction power is the factor that creates the value of a vacuum cleaner. Strong suction will help the machine deep clean the dirt in the carpet, nooks and crannies, and even pet hair that is difficult to remove. If there is not enough suction, the machine can only clean the debris on the surface but cannot remove the deep inside.

4 Parameters To Evaluate The Suction Power Of A Vacuum Cleaner

To make a preliminary assessment of the suction power of a vacuum cleaner, you need to read and understand the meaning of one of the four commonly encountered parameters on machines.

1. Airflow Index (CFM)

The Airflow Index represents the air flow strength from the floor surface to the bag/trash bin. In other words, it is the amount of air that the machine can absorb in one minute, usually in cubic feet - CFM (ft3/min). The higher the CFM value, the stronger the suction power. Typical vacuum cleaners will have an Airflow value of 50 - 100 CFM. You can use this parameter to evaluate the suction force. However, more than 50% of manufacturers will not include this indicator in the machine description.

2. Output power/ Suction power (Air Watts)

The Air Watts index is another parameter that helps evaluate the suction power of a vacuum cleaner. It means the amount of Watts used by the motor to draw an air unit, denoted AW. There is a report that an upright vacuum needs at least 100 AW, and that canister vacuums need at least 220 AW to get enough suction. Canister vacuums require more AW because they have to pass the trash through a long straw.

3. Motor power (Watts)

The most common parameter used to estimate suction force is Motor power. Watts is the unit of energy consumed by the motor. The higher the Watt rating, the more powerful the motor and the stronger the suction power is.

4. Input power (Ampere)

Similar to Watt, Ampere is a unit of energy consumption. But unlike the motor power index, the Ampere indicates the amount of power supplied to the entire machine, including the LED lights and the brush roll motor. Of course, most of the energy will be used for the engine. So the higher the Ampere number, the stronger the motor and the greater the suction force.

Top 4 brands of vacuum cleaners with the strong suction power

Just know 1 of the four parameters above, you can estimate whether the machine's suction power is suitable for your requirements or not. The article also introduces you to 4 top rated vacuum cleaners brands with strong suction power. 

Conclusion

You just learned how to read one of the four parameters that describe the suction power of a vacuum cleaner. Strong suction is important, but making best rated vacuum cleaners requires accessories and associated technologies. So you have to consider many more factors to choose the most suitable vacuum cleaner for you.
