Understanding Vacuum Suction Power

  

Understanding Vacuum Suction Power

In the quest for a clean and dust-free home, a powerful and reliable vacuum cleaner is an essential tool. But how can you navigate the vast array of options and find the perfect vacuum cleaner tailored to your needs? This article will explain the various suction power units, help you understand the key factors to consider when selecting a vacuum, and recommend LG products that are perfect for your home’s needs.

What are suction units?

Suction units are measurements that determine the power and effectiveness of a vacuum cleaner. Units are used to explain the power of a vacuum cleaner because they provide standardized measurements that allow consumers to compare the performance of different models.

Watts

One unit commonly used to express the power of a vacuum cleaner is watts (W). Watts represent the amount of electrical power required by the vacuum’s motor while cleaning, and the typical watt consumption for industrial-type vacuum cleaners is between 1000-4000W. Most conventional household vacuum cleaners have wattage ratings ranging from around 600-2000W. If you’re looking for a vacuum cleaner with powerful suction, you may want to consider one with higher wattage. A higher wattage often indicates a more powerful motor and potentially better suction.

Air pressure

Air pressure is measured in pascals (Pa) and refers to the force created by the vacuum to draw in air and household debris, such as dust, crumbs, and hair. The higher the air pressure, the greater the suction power. The air pressure generated by household vacuums typically ranges from around 20,000 Pa to 30,000 Pa, although some high-end models can exceed this range. Higher Pa ratings can be beneficial for deep cleaning carpets, removing stubborn debris, or dealing with challenging surfaces.


These suction units provide valuable insights into the performance and cleaning capabilities of vacuum cleaners, allowing consumers to make informed decisions when selecting the most suitable option for their cleaning needs. When choosing a vacuum cleaner based on value, we recommend a model with a suction power of 1600 Pa or higher and power consumption of 120W or above.

Factors to consider when choosing your vacuum

Factors to consider when choosing your vacuum

When selecting a household vacuum, it is recommended to consider a combination of factors, rather than relying solely on suction unit ratings. Many vacuums on the market are similar in terms of airflow efficiency and suction power, so considering other elements will ensure that you choose a vacuum cleaner that best meets your specific requirements.

Suction head design

The design of a vacuum’s suction head is key to its performance, as it is the part that comes into direct contact with the various surfaces being cleaned. The design determines how effectively it can create a seal with a surface, ensuring maximum suction and efficient dirt removal. A well-designed suction head will have features, such as brushes, that help loosen and lift dirt from the surface, making it easier for the vacuum's suction. A streamlined design allows the head to reach tight corners, under furniture, and along the baseboards of your home with ease, ensuring thorough cleaning in hard-to-reach areas.

Dust bag or dust bin?

Dust bag or dust bin?

Dust collection areas are designed to contain the dirt, dust, debris, and other particles that are suctioned into the vacuum cleaner, preventing them from scattering back into the areas being cleaned or being released back into the air. Modern vacuums use an internal dust bag or dust bin for this purpose.

Dust bags can become clogged more easily, restricting airflow through the vacuum cleaner and leading to a decrease in suction as the vacuum struggles to draw in air and debris effectively. However, high-quality dust bags are designed to maintain suction power even as they fill up. They can prevent clogging of the vacuum's filters, ensuring optimal airflow and sustained suction over extended periods.

Dust bin vacuums may experience a slight reduction in suction power as the bin fills up. It’s important to empty the dust bin regularly to maintain your vacuum’s performance. Dust bins are also more environmentally friendly, as you are not throwing anything extra away when emptying the vacuum. This means additional cost savings over time, as you will not need to regularly re-purchase disposable dust bags. Some dust bins are washable, allowing for thorough cleaning, and can have transparent or semi-transparent designs, enabling you to monitor the accumulated debris inside, preventing overfilling.

Dust collection technology

Modern vacuums also use different dust collection technologies. In vacuum cleaners with disposable dust bags, the most common technology is filter-based, using one or more filters to trap and contain dirt and debris. This system is suitable for customers who want the convenience of disposing of dust bags or who have asthma or allergies and want to closely monitor their vacuum’s filtration components.
Cyclone-separated dust collection uses cyclonic action to separate dirt and debris from the air. The vortex-like airflow within the vacuum causes larger and heavier particles to be thrown outward and collected in a separate chamber or bin while the cleaner air continues through the vacuum's filtration system. This helps to prevent the filters from clogging and maintains suction power. By separating debris from the airflow before it reaches the filters, cyclone-separated dust collection systems can extend the life of the filters and reduce maintenance requirements.

Major advantages of LG vacuum cleaners

If you’re looking for a vacuum cleaner with impressive suction power and cleaning ability, the range of LG vacuums could be for you. LG is known for its commitment to innovative technology and makes vacuum cleaners with many impressive advantages.

LG’s unique dust collection technology

The LG Smart Inverter Motor™ inside LG vacuum cleaners drives the fan at a rapid speed, creating an internal cyclonic airflow within the device's Axial Turbo Cyclone chambers. This cyclonic action creates robust and efficient suctioning performance, effectively separating dust, hair, and other dirt from the clean air. This design prevents dust from clogging the filter system and ensures that the suction power remains consistent. The motor operates without friction, resulting in reduced wear and tear and enhanced durability. LG is so confident in its durability that the Smart Inverter Motor™ is backed by a 10-year parts warranty, providing customers with added peace of mind.

LG’s self-emptying system

Designed to improve the vacuum-emptying portion of cleaning, LG created the LG Auto Emptying All-in-One Tower™. When docked, compatible LG vacuums are automatically emptied into the tower’s larger dust container, relieving you from the need to manually empty your vacuum after use. The tower comes with a 3-step filtration system, hygienically locking away dirt and filtering out particles to protect you from breathing in any dust or pet hair that could be released into the air during the emptying process of other vacuum cleaners. With built-in space to store vacuum accessories, enjoy a streamlined cleaning routine and only replace the dustbag in the tower approximately every 3 months! The dustbag replacement schedule may vary depending on the actual usage environment.

LG’s multi-surface vacuum head

LG’s multi-surface vacuum head

LG has designed vacuum products that combine ease of use with impressive performance. The LG Vacuum Slim Power Drive™ Nozzle was designed for use on different surface, like carpets, tiles, and hard floors, saving you time that you would have had to spend switching out single-purpose heads when using other vacuum models.1

Unique filtration system

Many LG vacuums come equipped with a five-stage filtration system, created to easily filter dust, pollen, and pet hair out of the air within the vacuum. Large, medium, and small dust is separated layer by layer, and finally, only clean air is released from the machine. This system is especially suitable for customers with asthma or allergies to fine dust and pollen. The metal filter, cloth pre-filter, and fine dust filters can be easily removed and washed to maintain your vacuum’s performance. Filters should be hand-washed in clean water and left to completely air-dry before being placed back into the vacuum.

Easy and smart maintenance
