If you have an old 1, toss it. Buy a new one to keep the vacuum cleaner working and sucking like new. I have an old vacuum that is superior to anything on the market today. I say this BC I tested 8 Vacs to replace this old Mach 5th and Wide Path BC and its 12 amp suction power. Replacement of brushes, belts Beat A Vacuum reaches 1k. It's time for my old lady to be happy and suck well! OLD MAN KNOWS TECHNOLOGY!
