Hi & welcome, Alan!  Recently you wrote in a message to alexander koryagin:

              That's a good start.  It may be all some of our readers can take in   
   at once too.  But because we have students here who are operating at different   
   levels, I often reply briefly & then elaborate just as you did.  :-)   
      
      
      
    ak>  It is a light fluffy stick with a handle, covered with   
    ak>  long fibers. Every fiber (if the thing is not a counterfeit)   
    ak>  is electrified electrostatically. As a result when I sweep   
    ak>  it over the dusty surface all dust clings to the thing's   
    ak>  fibers. To remove the clung dust I should put it out of my   
    ak>  window and shake it.   
      
    AI>  I have something like that but it is not charged

              Yes... IMHO almost any combination of soft fluffy material + a long   
   permanently attached handle + the ability to remove dust easily from irregular   
   surfaces without scratching them could be referred to as a "duster".   
      
              Now, as to fancier names... before humans had synthetic fibres they   
   used feathers or lambswool to make dusters.  They used wool to make carpets as   
   well.  I remember being warned, as a child, not to shuffle my feet on a carpet   
   lest I give some other person a "shock"... and I remember how children used to   
   rub inflated balloons on their heads to make their hair stand on end.  I think   
   our ancestors understood on some level that wool has electrostatic properties.   
   They didn't know the currently fashionable advertising terminology... and many   
   of them had only a grade three education at best... but they knew what works &   
   what doesn't.  My parents & grandparents were reducing, re-using and recycling   
   before the words became a popular slogan.  OTOH I had "older" parents....  ;-)
