The working principle of a vacuum cleaner is that the motor of the vacuum cleaner rotates at high speed and sucks in air from the suction port, creating a certain vacuum in the dust box. Dust enters the filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe. The dust is left in the filter bag, and the filtered air enters the motor through a layer of filter plates. This layer of filter plates is a protective barrier to prevent the dust bag from breaking and dust from being sucked into the motor, The air entering the motor flows out through the motor, and due to the continuous wear and tear of the carbon brush during the operation of the motor, another filter is added before it flows out of the vacuum cleaner. The finer the filtering material, the cleaner the air can be filtered, but the lower the air permeability, which affects the air volume sucked in by the motor and reduces the efficiency of the vacuum cleaner. But for users, comfort and cleanliness are the main priority. Its breathability is low, so it is made into a wavy shape to increase the breathable area. Some of these filtering materials can also be cleaned repeatedly. Any filtering material has a "lifespan", which means that after long-term use, the micropores of the filtering material have been blocked by small particles of dust. Therefore, paper dust bags are ideal, disposable after use, hygienic and convenient. After cleaning the cloth dust filter bag, the fibers will harden, affecting the filtration and breathability effects. SMS three-layer composite filter material is washable, but has slightly lower air permeability. Product classification: Horizontal vacuum cleaners are commonly used in the Asian and European markets by shape, accounting for over 80% of the overall market. Its characteristic is its compact appearance and convenient storage. Horizontal vacuum cleaners are also divided into "dust box vacuum cleaners" and "dust bag vacuum cleaners". Vertical American markets are common and suitable for large-scale carpet cleaning. The handheld model is compact and very convenient to carry and use. It is mainly used for cleaning the car interior and has good effects on keyboards, appliances, etc. The disadvantage is that the power is small and the suction is not strong enough. Bucket type commercial vacuum cleaners are mostly used by cleaning companies, hotels, and office buildings, characterized by large capacity and the ability to absorb water. The push rod type is gradually increasing, mostly rechargeable, characterized by its compact size and convenient use. By function, robots automatically clean the dust on the floor, hair and debris, and automatically return to charging after the cleaning task is completed. The core technology of intelligent vacuum cleaners is the chip and software inside. High end vacuum cleaner, which can automatically clean and charge, has the advantages of low noise, small size, and easy access to areas that traditional vacuum cleaners cannot reach. Portable vacuum cleaners generally come in four forms: shoulder type vacuum cleaners: small in size, carried on the shoulder when used, with low power output. Rod vacuum cleaner: shaped like a rod, with a handle at the upper end and a suction nozzle at the lower end, with a low power output. Portable vacuum cleaner: smaller in size, can be used directly in the hand, with low power output. Micro vacuum cleaner: Multi battery powered, smaller in size, commonly used for cleaning clothes, instruments, etc., with low power. The high-end vacuum cleaner of the central vacuum system places the vacuum cleaner in places outside the main living area, such as underground equipment floors, garages, cleaning rooms, etc. The vacuum pipeline is embedded in the wall, leaving only small and beautiful vacuum sockets on the wall. When cleaning is needed, only one hose needs to be inserted into the vacuum outlet. At this time, the system automatically activates the main switch, and all dust, paper scraps, cigarette butts, and harmful microorganisms of all sizes are left, Even the unpleasant odors such as smoke in the guest rooms are transmitted to the central collection station through tightly sealed pipelines. Anyone can perform full or partial cleaning at any time, ensuring the cleanest indoor environment. Its cleaning and processing capacity is 5 times that of a regular vacuum cleaner, and the length of the hose can be arbitrarily selected. This type of system is already a mandatory system in European and American countries, and some high-end properties in China have adopted this advanced technology. Water filtration vacuum cleaner uses water as the filtering medium to dissolve and lock the vast majority of microorganisms such as dust, garbage, and bacteria into the water tank when they are sucked in by strong suction. Wet the dust with water to avoid the overflow of small dust during vacuum cleaning; Inhalation of gas through water purification, dissolution of allergens, bacteria, and other microorganisms. Then, further filtration is carried out through HEPA, high-efficiency filter cotton, etc., ensuring the perfect and efficient water filtration through these three major purification systems. When water filtration technology was first developed, it was aimed at people who are prone to allergies. By dissolving and locking in dust, particles, allergens, pollen, dust mites, small microorganisms, etc. through water, it avoids the allergic phenomenon caused by unclean air during the vacuum cleaning process. Portable Mini Vacuum Cleaner Portable Mini Vacuum Cleaner is lightweight and flexible, with a convenient lifting design. As long as you pick it up and lightly press it with your hand, you can easily vacuum. The strap style design allows it to be carried around the waist for operation. Using a large suction head can suck any object on the ground (excluding water), using a wide suction head can suck items with gaps (the head of the wide suction head has hair to sweep, which can clean dust in the gaps), and using a hose to vacuum can be carried on the body. It can not only suck on sofas, curtains, but also dust from ceilings, computer keyboards, bed surfaces, and various household appliance surfaces. Equipped with a small square brush that can turn, it can be used for computer keyboard dust removal, cleaning small areas of debris, and vacuuming pets. It can also remove dust and dirt hidden in every blind corner and narrow seam, improving cleaning efficiency and making it more convenient to use. As the name suggests, the main function of a mite removal vacuum cleaner is to remove and kill mites. Medical grade ultraviolet lamp tubes can remove mites and sterilize household items such as beds, sofas, bath towels, baby crawling blankets, plush toys, etc. The 400W suction can completely eradicate the living environment of mites and suck away the infectious agents of mite bacteria
