How do i open my canister vacuum

Open the bag door and grip the bumpers with a set of pliers. The bumpers cover a set of locking keys which will slide all the way forward and out. The back of the vac will then lift off and the top and bottom will open hinging forward like a **** shell. Observe how the front door hinge clips into the lower body before opening teh unit.
If you do this , tag your wires and observe how the pieces interlock. Open the vac with it laying upside down on a piece of carpet.
It will NOT go back togerther unless it is perfectly reassembled , so don't force it.
Post your problem before opening and I will walk you through the reapir
