Vacuum cleaner filtration systems vary significantly in performance, maintenance requirements, and environmental impact. Understanding the differences between dust bag, dust cup, and water filtration methods can help users choose the best option for their needs.
With dust bag filtration, the vacuum cleaner captures particles as small as 0.3 microns with an efficiency of up to 99.99%. However, as the dust bag fills over time, suction power decreases, which means the user may not always be able to replace it after every use. Additionally, dust bags can become breeding grounds for microorganisms like dust mites, leading to secondary pollution when the bag is emptied. While they are easy to clean and don’t require daily maintenance, dust bags tend to lose their filtering efficiency over time. The fabric pores may open, reducing effectiveness and requiring replacement eventually. This makes them ideal for industries such as factories, hotels, and car detailing services.
Dust cup filtration systems work by using high-speed motor rotation to separate dirt and air, then passing the remaining particles through a HEPA filter to purify the exhaust air. One major advantage is that the dust cup doesn’t need frequent replacement. However, cleaning is usually done only after the vacuuming session is complete, which might lead to less immediate hygiene benefits compared to other systems.
Water filtration is one of the most effective methods, as it uses water as a medium to trap and dissolve dust and microorganisms. As the air passes through the water, most particles are captured, and the remaining debris is filtered further. This results in exhaust air that is often cleaner than the ambient air. However, this system requires careful design and strong waterproof protection for the motor, making it more complex and expensive. Water-based vacuums are known for their strong suction and purified exhaust, but they also come with downsides. Users must drain and clean the water tank after each use. If not properly maintained, the system can develop mold, odors, or rust. These vacuums are well-suited for home, office, and hotel environments where cleanliness is a priority.
road roller, also known as a compaction, is a kind of equipment for building roads.
Road roller belongs to the category of road equipment in construction machinery, widely used in high-grade highways, railways, airport runways, dams, stadiums and other large-scale engineering projects fill compaction operations, can roll sandy, semi-cohesive and cohesive soil, subgrade stabilized soil and asphalt concrete pavement layer, roller with the gravity of the machine itself, suitable for all kinds of compaction operations, so that the rolled layer produces permanent deformation and compacting.
