My first mighty might mite vac was bought about 28 years ago. Tried a couple alternatives in the intervening years but always ended up w/ the ole 3.0 hp / 9.0 amp MM vac. Went through two cord replacements, then when a third cord was needed I decided to move on and retired my faithful MM to garage duty. This replacement model is better than gr8 for the $....it's about what I paid for our original 28 years ago but w/ >30% more power.
