Vacuum Cleaners Discussions

I like that.  You have the makings of a new age vacuum cleaner designer, erhh, I mean engineer.

On the old Connies, 4 screws less than a 1/2 inch long [agitator brush screws] held the entire machine together including the motor mounted in an inverted position with the commutator end of the motor frame at the bottom.  Simple design and function.  The motor's fans were directly under the pre-motor filter and paper bag drawing the expelled bag air circulating around in the huge half globe bag compartment directly into the motor cavity for motor cooling.  An important feature.  Why?  With the vacuum's weight atop the exhaust [for floatation] the Connie motors would have a predisposition to overheat.  Never did if bag and filter were maintained properly.  Excellent bypass motor design despite the added imposition going back over 50 years.

you would think that because of the possibility of overheating the motor,despite the 'dome' of air ..that they would add a small cooling fan...just in case....i say this because ive heard that back in the day is when stuff was built to last....quality over quantity.
