The Ultimate Guide to Superior Suction

Why Suction Power is Essential in a Vacuum for Effective Cleaning

As trusted experts in the vacuum industry, Think Vacuums has built a solid reputation over decades of experience.

Our deep understanding of household vacuums and central vacuums allows us to provide unparalleled insight into what makes a vacuum effective, particularly focusing on one of the most misunderstood aspects: suction power.

For consumers looking to invest in a vacuum cleaner, understanding suction power is crucial for making an informed decision.

Understanding Suction Power

The Role of Suction Power

• Suction power determines a vacuum cleaner’s ability to lift debris from surfaces.

While it's only one aspect of a vacuum's performance, it plays a significant role in how effectively your vacuum will clean various surfaces, from carpets to hardwood floors.

However, many consumers find it challenging to differentiate between low and high suction power due to the variety of measurements used.

Key Measurements of Suction Power

Airflow (CFM)
One of the most critical measurements is airflow, noted as CFM (cubic feet per minute).

• Airflow represents the power of the airflow from the surface to the vacuum’s dust bag or bin.

This measurement indicates how much air the unit can move per minute. Although essential, many manufacturers do not provide this measurement, with less than half listing it in their specifications. At Think Vacuums, we emphasize the importance of CFM, as it directly correlates to cleaning efficiency.

 

Air Watts (AW)

Air Watts is a technical term often encountered, especially in the context of vacuum cleaners and other suction devices, yet it remains misunderstood by many

• AW measurement specifies the amount of power a vacuum uses to move a unit of air through its nozzle.

It's a favorite among savvy consumers because it more accurately reflects the vacuum's real-world performance, unlike traditional wattage ratings that only measure power consumption. Air Wattage provides insight into how efficiently the vacuum converts power into suction.

A higher Air Wattage indicates better cleaning power and effectiveness, making it a crucial element to consider when choosing a vacuum. This ensures you get the best performance for maintaining clean floors and surfaces in your home.

 

Water Lift (Inches of H2O)
This measurement is part of the seal suction test, an evaluation where the vacuum’s ability to lift water in a sealed tube is assessed. The test involves creating a vacuum inside a transparent tube with water, measuring how high the vacuum can lift the water column.

• Water lift provides insight into the vacuum’s maximum suction strength, which is a critical factor in determining overall performance.

While this test is more common in professional settings, understanding this measure can be beneficial for consumers seeking powerful models for heavy-duty cleaning tasks, such as removing deep-seated dirt from carpets or tackling stubborn pet hair. By knowing the vacuum’s suction capabilities, consumers can make informed decisions when selecting a model that suits their cleaning needs.

 

Watts
Watts refer to the motor's power consumption rather than its cleaning performance. A higher wattage suggests a more powerful motor, but it does not necessarily equate to better suction. This means that while a vacuum with a high wattage might have a strong motor, it doesn't always guarantee superior cleaning efficiency. There's an ongoing debate about the correlation between motor power and suction efficiency, as some experts argue that other factors play a significant role.

• Its important to look beyond wattage alone and considering additional measurements like cubic feet per minute (CFM), which measures airflow, and air watts (AW), which indicates suction power.

These metrics provide a more comprehensive assessment of a vacuum's capability, helping consumers make informed decisions based on the full picture of a machine's performance.

Practical Tips for Evaluating Suction Power

1. Read the Specifications: Always examine the product's specifications for CFM, AW, and water lift if available. These numbers give you a clearer picture of the vacuum's potential.
2. Perform a Quick Test: If possible, test the vacuum in-store. Engage the "carpet mode" and power the unit to maximum. Attach the floor head to a wall; a high-suction vacuum will remain attached without support.
3. Consider the Application: Different scenarios require different suction power. For hard floors, high airflow might be more critical, whereas, for carpets, water lift could be more indicative of performance.
4. Consult Experts: At Think Vacuums, our team of experts is always ready to guide you through the selection process, ensuring you choose a vacuum that best suits your needs.
