Futon-Specific Brush UV Dust Mite Cleaner ・Vacuum cleaner nozzle ・Operation confirmed ・3 batteries included ・High-speed tapping ・ON/OFF with tip power button ・Rotating part easily removable Thank you for viewing. Although it is almost unused, it has been stored at home for a long time. The battery cover is looser than when purchased, so we recommend using tape to secure it. I think it is generally clean, but I will sell it to someone who understands this. ◯Detailed supplement (the following is manufacturer's details) A UV disinfection futon brush that you just attach to your vacuum cleaner. It taps out dust mite carcasses and pollen efficiently with high-speed vibrations of up to about 3500 rotations per minute, and sucks them up. Autumn and winter, after the dust mites' breeding season, is when there are many carcasses. Let's freshen up your futon with this. The dust is sucked into the vacuum cleaner, so it's easy to use and maintain. By the way, I have only used it a few times with the rotation off, so it is unused as a dust mite brush.
