The Green Monster!
My Dad purchased a New Kirby D80 in 1968, Now I was only 7 years old and that thing weighed a ton, me and my sister use to call it the Green Monster! It would suck the rugs off the floor, my legos, my sisters doll clothes and more! Dad purchased the whole lot, moth ball crystilizer, shampoo/foamer thingy and all those other crazy attachments, grinder,shoe polisher and who knows what else, loud as all get out too! Back in 1968 he paid close to $1000.00 for that thing according to paperwork I found a couple of years ago!
I hated using attachments I would always pinch my fingers with that damn thing you had to turn and then from time to time that rubber belt inside the floor brush bar would slip off and then it was hell to put back on!
Only thing I was mad about was Dad traded the Sears Kenmore Missile Vacuum (looked like a bomb!) in on the Kirby!
I loved that bomb looking vacuum cleaner and it also had a great soft humming sound almost would put you to sleep!
