and about Dial a Matic...
its too bad the design was sold and abandoned. would be hard to reintroduce since others have already improved it greatly. in my fantasies, i see the DAMs aluminum nozzle redesigned with an all-new precision casting. i can see the original nozzle looseing a couple pounds. the motor is also too heavy! the bag and secondary filter would be "tweaked". the cleaner would grow real, useable REAR WHEELS!. unless the nozzle is feather-light, an articulate height adjuster is mandatory. and, of course, the cleaner would have an active wand, a la Quick Draw. one thing to keep, the DAMs lovely design.
