Does the Cordless Smart Vacuum Cleaner support whole-machine sealed filtration? How to avoid secondary pollution?

The whole-machine sealed filtration system of the Cordless Smart Vacuum Cleaner is its core technology to avoid secondary pollution. Each component connection of the device from the suction head to the exhaust port is sealed with high-precision processing, such as the installation of sealing gaskets around the cyclone components, and the use of pressurized rubber sealing rings on the contact surface between the filter and the body, etc., to ensure that the airflow path is completely closed. This design prevents dust from leaking from the gaps during the vacuuming process, especially when running at high suction, the sealing can effectively resist the escape of fine dust caused by changes in airflow pressure.
The centrifugal force of more than 79,000G generated by the high-speed rotating cyclone separates large dust particles from the airflow and throws them into the dust collection barrel, reducing the burden on the filter and avoiding clogging. The use of H13-level high-efficiency filter material can adsorb and lock 99.97% of particles as small as 0.1 microns (such as pollen, bacteria, viruses, etc.), and some advanced systems can even filter 99.99% of 0.1 micron particles. Some products combine primary filters, cyclone separation layers, front/rear filters and HEPA filters to form 5-6 filter barriers, intercepting particles of different sizes step by step. The garbage dumping path is controlled by a mechanical switch to reduce the risk of manual contact with dust; some systems also use rubber scrapers to remove residual dust to avoid dust during dumping.
The sealing performance of the equipment must pass strict testing, such as verifying whether it leaks under high pressure difference conditions based on standards such as AS/NZS 60335.2.69. Some manufacturers use laboratory-level aerosol tests to simulate the movement trajectory of fine dust in the equipment to ensure that the sealing design has no dead ends. Automatically adjust the suction strength according to the ground type (such as carpet, hard floor) or dust concentration to avoid overloading the filtration system due to excessive suction, thereby reducing the risk of leakage. The precise arrangement of the cyclone components and the symmetrical design of the central axis improve the airflow efficiency and reduce turbulence, ensuring that the dust is stably directed to the dust collection cylinder.
Some devices are equipped with sensors to monitor the filter blockage in real time, and remind users to clean or replace the filter through the display or prompt sound to avoid secondary pollution caused by filter failure. Using piezoelectric sensors or optical detection technology, the distribution of ground dust and cleaning progress can be displayed in real time to help users clean high-pollution areas in a targeted manner and reduce the risk of leakage caused by repeated cleaning.
High suction requires stronger airflow power, but may increase filter pressure. By upgrading cyclone separation technology (such as multi-cone cyclone design), the filter burden can be reduced while the suction is increased to maintain filtration efficiency. For ultrafine particles below 0.1 microns (such as viruses, PM0.1), a higher density HEPA filter material is required, and the filter folding process is optimized to increase the effective filtration area while avoiding excessive airflow resistance. The aging resistance of the sealing material is very important. Some manufacturers use silicone or fluororubber materials to ensure that they remain elastic after long-term use in high temperature and high humidity environments to prevent leakage caused by deformation of the sealing ring.
It is recommended to clean the filter every month and check whether the sealing ring is intact. When dumping the dust collector, keep it away from your face to avoid inhaling dust. High temperature or humid environment may affect the sealing performance and the usage conditions in the product instructions must be followed.
