Personally, I feel that the vacuum cleaner used in bed will not make me uncomfortable in other places.
The power of bed vacuum cleaner should not be very large, generally more than 300W is enough, and wireless charging is also possible.
The functions of bed vacuum cleaner are: powerful flapping, ultraviolet sterilization and mite removal, and powerful vacuum cleaner.
Those who suck away dust in the air should belong to air purifiers, and domestic ones are generally more expensive, ranging from several thousand.
