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.
Wet and dry vacuum cleaners operate using a similar principle to regular vacuums but with additional features that allow them to handle liquids. Here’s how they work:
They have a motor that creates suction, drawing debris or liquid into a storage tank. The tank is divided to accommodate both wet and dry materials. When vacuuming liquids, the tank captures the liquid without it reaching the motor, thanks to protective barriers and specialised filters.
Wet and dry vacuums often have interchangeable filters for dry and wet cleaning. Foam filters or sleeves are used when picking up liquids to prevent damage to the vacuum's motor, while more traditional filters or bags are used for dry debris.
The tanks are typically larger and more durable than those of regular vacuums, designed to hold substantial amounts of liquid and debris. This makes them ideal for heavy-duty cleaning jobs.
Using a wet and dry vacuum cleaner involves a few straightforward steps, but it’s important to follow the manufacturer’s instructions for optimal performance.
Before starting, ensure the vacuum is set up correctly for the type of cleaning you plan to do. For dry cleaning, make sure the dust bag or container is in place. For wet cleaning, check that the dust bag is removed, and the appropriate filter or foam sleeve is installed to handle liquids.
Some models have different modes for wet and dry cleaning. Set the vacuum to the correct mode if applicable. For dry debris, use the standard nozzle or brush attachments. For liquids, switch to the nozzle designed for wet pickup. Make sure to move slowly over wet areas to ensure thorough suction of the liquid.
After cleaning, empty the tank promptly. If you’ve vacuumed up liquids, be sure to drain the tank and rinse it out to prevent odours and bacteria growth.
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 wet and dry vacuum cleaner is a versatile cleaning device designed to handle both liquid spills and dry debris. Unlike traditional vacuum cleaners, which are typically limited to dry dirt and dust, wet and dry vacuums can suck up water, making them ideal for a variety of cleaning tasks, from household spills to more demanding jobs like cleaning up after renovations or in workshops. These vacuums are commonly used in both residential and commercial settings due to their robust design and ability to tackle a wide range of cleaning challenges.
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.
