Dust cyclone for vacuum cleaner

This is a dust cyclone for Electrolux vacuum cleaners (with upward facing hose connector). It uses a cyclone separation technique to separate most of the dust before it enters the vacuum cleaner. It works rather well, separates dust and hair very good. Gravel and larger pieces tend to swivel around inside and make some noise, but it can easily be pored into the bin by removing the cyclone adapter. About noise, yeah... lots of noise, swirling, howling, whining, rattling noise. :)

Be warned tho
