Using this wireless vacuum cleaner is a breeze. First, make sure the battery is charged. You can use the included charging cable, which is about 1m long, to charge it. Once it's charged, simply turn it on and start moving it over your bed sheets, quilts, or carpets. The machine will use high - frequency patting and sound waves to suck the bugs into the dustbin. When the dustbin gets full, open it and empty the contents. It has a capacity of about 0.2L, so you won't have to do this too often. As for maintenance, keep the machine clean. Wipe it with a dry cloth regularly. Don't expose it to water or extreme temperatures. Also, make sure to charge the battery when it runs low to keep the machine working properly.
