First thing- the vacuum was donated to my work. Was kept in good condition so after 2 days of use belt broke ( the original factory belt) so I look up the numbers on Amazon for replacement ( and google) and my goodness...i could not find a match on serial or modle number . Even this one didn't match nor the vacuum modle but it was closest match I could find. It worked!! Though so that's the reason for 5 stars.
