FAQs
Comparing the suction power of vacuum cleaners can be challenging because manufacturers use different metrics to describe performance. Here are some key factors and specifications to consider when evaluating vacuum suction power.
• Air Watts (AW): A measure of the vacuum’s effectiveness in using power to create airflow and suction. A higher air watt rating generally indicates stronger suction. This is a more accurate measure than simply looking at the motor's wattage or amperage.
• Cubic Feet per Minute (CFM): CFM measures the volume of air that the vacuum can move in a minute. A higher CFM indicates better airflow, which is critical for effective suction and cleaning performance.
• Water Lift (Sealed Suction): This metric measures the vacuum’s ability to lift water vertically and is a good indicator of suction strength. Higher water lift values suggest better suction performance, especially for pulling dirt and debris from carpets.
• Motor Power (Wattage/Amperage): While motor power can indicate potential suction strength, it is not always a direct correlation. A more efficient design can make better use of available power, so it’s important to consider this alongside other metrics.
A powerful vacuum cleaner can be identified by several key features:
• Measured in watts or air watts, suction power indicates the vacuum’s ability to lift dirt from surfaces. Higher suction power generally means more effective cleaning.
• Measured in cubic feet per minute (CFM), airflow refers to the volume of air moved through the vacuum. A high CFM rating usually correlates with better cleaning performance.
• The motor’s power, often measured in amps or watts, can indicate overall performance. However, efficiency and design also play roles in a vacuum's effectiveness.
• A high-quality filtration system, such as a HEPA filter, ensures that the vacuum traps dust and allergens effectively.
• An effective brush roll helps dislodge dirt from carpets and is crucial for removing pet hair and debris from various surfaces.
A barrel vacuum, also known as a canister vacuum, is a type of vacuum cleaner characterised by its design, where the motor and dust container are housed in a separate unit, or "barrel," connected to a flexible hose and cleaning nozzle. This design contrasts with stick vacuums, which combine the motor and suction head in a single, upright unit.
Key Features and Benefits:
Barrel vacuums are known for their versatility, as they can easily maneuver around furniture and reach into tight spaces. The flexible hose and variety of attachments make them suitable for cleaning a wide range of surfaces, including carpets, hardwood floors, stairs, upholstery, and drapes.
Barrel vacuums often offer strong suction power and efficient cleaning performance. They typically have a larger motor and dust capacity than stick vacuums, making them ideal for homes that require thorough cleaning.
Although the main unit may be heavier, the separate design allows the user to carry only the lightweight hose and wand during cleaning. This can make cleaning less tiring, especially for extended periods or in large areas.
Most barrel vacuums come with a variety of attachments, such as crevice tools, dusting brushes, and pet hair tools, allowing for specialised cleaning tasks.
If your vacuum cleaner is losing suction, there are several steps you can take to restore its performance and maintain optimal suction over time.
The most common cause of suction loss is a clog in the hose, brush roll, or air pathways. Inspect these areas for any blockages caused by debris or tangled hair, and remove them as necessary. A full dust bin or vacuum bag can significantly reduce suction power. Empty the bin or replace the bag regularly to ensure consistent performance.
Filters can become clogged with dust and debris over time, reducing airflow and suction. Check your vacuum filters and clean or replace them according to the manufacturer's recommendations. HEPA filters, in particular, may need more frequent attention.
The brush roll can become entangled with hair, string, or other debris, which can impede its rotation and affect suction. Clean the brush roll regularly to keep it free from obstructions.
Examine the hose and connections for any cracks, holes, or loose fittings that could cause air leaks, leading to reduced suction. Replace damaged parts to maintain a tight seal.
If you have addressed all the above issues and still experience suction loss, it may be time to look into a replacement.
