I picked this up at a thrift shop for $3 today. Its a Regina ElectrikBroom 3 speed. The motor was a bit dry when I bought it so I tore it apart and lubed it. Seems to work OK. I get the feeling if I washed the cloth bag it would have alot more suction. Does anybody know how to remove the bag? Also, how old are these, I hear they are from the 60's
