Modern cordless smart vacuum cleaners are usually equipped with a multi-layer filter system, including a primary filter, a HEPA filter or similar high-efficiency filter material. First of all, it is necessary to clarify the function and position of each filter so that targeted cleaning can be carried out. For washable filters, it is recommended to clean them at least once a month. Use warm water (avoid hot water or chemical detergents) to gently rinse the filter to remove attached dust, hair and tiny particles. For non-washable filters, use the cleaning tool or soft brush that comes with the vacuum cleaner to gently brush off the dust.
The cleaned filter should be placed in a cool and ventilated place to air dry naturally, and ensure that it is thoroughly dry before putting it back into the vacuum cleaner. Avoid using heat sources such as dryers or hair dryers to avoid damaging the filter structure. Every time you clean it, carefully check the filter for signs of damage, deformation or aging. If found, replace it with a new filter in time to ensure that the filtration effect is not affected.
Regularly replace the filter in the vacuum cleaner according to the manufacturer's recommendations. This is usually based on the use time of the filter, the number of cleanings, or the frequency of use of the vacuum cleaner. To ensure the best filtration effect, it is recommended to purchase and use the original filter cartridges recommended by the manufacturer. Avoid using uncertified substitutes to avoid reducing filtration efficiency or damaging the vacuum cleaner. Before replacing the filter cartridge, check that the other parts of the vacuum cleaner are clean and unobstructed. At the same time, make sure that the packaging of the new filter cartridge is intact and avoid contamination during the replacement process.
After each use, clean the dust and debris in the dust box in time. Regularly (such as every quarter) check and clean the vacuum cleaner's suction ducts and connecting parts to ensure that they are unobstructed. Although these parts usually do not require users to clean them themselves, dust may accumulate on the motor and fan during long-term use. If the performance of the vacuum cleaner has significantly decreased, it is recommended to contact a professional maintenance personnel for cleaning and maintenance. When using the vacuum cleaner, avoid inhaling large particles, sharp objects or wet materials. These substances may damage the filter and internal components, reduce filtration efficiency and shorten the life of the vacuum cleaner.
Some high-end cordless smart vacuum cleaners have intelligent monitoring and reminder functions. They can detect the status of the filter and filter cartridge and remind users through indicator lights or mobile phone apps when they need to be cleaned or replaced. Develop a preventive maintenance plan and regularly check the vacuum cleaner's functions. This includes checking suction, noise, vibration, and the cleaning and replacement of filters and cartridges. If the vacuum cleaner fails or performance deteriorates significantly, it is recommended to contact the manufacturer or a professional repair service in time. They can provide professional repair and maintenance services to ensure that the vacuum cleaner returns to optimal performance.
