FILTER QUEENS Do not clog under normal use-the one I bought from a yard sale was one of the most CLOGGED vacuums I dealt with-probably why it was being sold.Its a nice vacuum.I think owner-user abuse for it.There was no cone in the machine.It was PACKED with Christmas tree needles.Same with the hose and powernozzle.The motor filter under the conegard was clogged-I had to replace it.And to top it off there was a package of filter cones and motor filters with the machine when I bought it!And vacuum techs use these machines to clean out vacuums brought into them for service-knew of two vac shops that used some old filter queen to clean out customer machines.Both emptied the machine daily and replaced its cone.
