AUTO EMPTY DUSTBIN
Get rid of vacuum dust without the hassle of getting your hands dirty. Simply detach the dustbin from your Jet Stick and insert into the Clean Station™. Once in, the bottom lid of the dustbin is designed to open, to securely empty vacuum dust from the bin without scattering it back into the air.
