This is not a childhood memory but the canister vac. was a hand-me-down from my childhood. One year ,on the last day of a week long "Spring" cleaning marathon I was happily and proudly vacuuming the last room, the open living-kitchen-dining-family room, I happened to look up and OMG SMOKE ! no FOG!! no!! THE VAC BAG HAD EXPLODED!!!!!
The memory still brings tears to my eyes!
