I am shopping for a vacuum cleaner with as much suction as the 1920 Kirby that my grandfather bought from a local 2nd-hand dealer. <-That machine REALLY HAD A STRONG SUCTION until the motor did eventually burn out (1990.)

Which type of home vac offers what I am seeking (either Stand-up or Canister)?
