I almost never use my Kirby D50 because I don't want a mess in the bag to empty. But, today I had a lot of spilled shredded paper from emptying the shredder and thought it was a good chance to give it a spin.
Back in the 80's I used to love to find and buy the D-50, D-80 from Bo Jackers that came around. As well as take them on trade ins. As they made great Recondition Kirbys to sell in the Vacuum Shop .
