Nice find, Terry.
We have a Panasonic MC6220 3 speed upright.
Back in the day (through the '80s and early '90s), it was the number one upright in Consumers Report.
It has a 7 amp motor that generates great suction and is fairly quiet.
I put together a great set of attachements for it with a 10' hose making it the vacuum of choice by my family.
My daughter has it now and absolutely loves it.
She couldn't believe we were giving her that vac for her apartment at the time.
Still runs great since it has been well maintained over the years.
My understanding is it was the Japanese version of the Hoover DAM, basically improving on the shortcomings of the Hoover.
Too bad that 12 amps had to become the standard.
It changed the pleasantness of the machine and was not necessary/didn't really improve performance.
Funny how the configuration of that vac (clean air system) is now basically the standard for most uprights produced today.
Again, great find and enjoy while you have it!!
BTW, Happy Easter .... hope you're having a great day.
Lets talk soon!!
