It's the clumping clay litter Rick, and all the Tims Cof
Very useful on a busy sunny Saturday when yer zipping between chores and it beats the rubberband and plastic bag around the man partz. Ok, just kidding.
But there have been some days when I forget to drain the spout before heading home from work, stopping at some store or other for this n that. In the sub cold weather it's a real bastard and a contortionist's dance to hold it all in while dropping the door keys in the snow carrying groceries and so on...One time in January I said to hell with it, stood in the yard and blissfully pissed my 501s - I figured I could hop in the shower and start a laundry right away. 
The 1996 video manual is a hoot - 65 minutes of my life I won't get back. It's a reshoot of the G3 video manual with added opening sequences.
Begins with 2 Independent Reports from Dr Joseph A Belland, MD, Georgetown University School of Medicine showing scary photo blowups of bugs & germs & spores and how gramma's old vacuum simply spewed it all back into the air. Then Susan Goldsmith, Director of Technical Services Interbasic Resources, Inc demonstrates an upside down G5 in a sealed chamber ingesting test dirt and spewing NOTHING out the backside according to very important looking instruments. No arguments from me.
next, Jim Salk, Senior VP of Marketing introduces Gene Windfeldt, President/CEO of The Kirby Company. Jim returns at the end of the video to chat about opportunities to earn hundreds of $ per month demonstrating Kirbys door to door - just call your local Kirby Distributor.
The User Manual supplements the book Manual and covers every detail such as how to clean your Zip Brush and turn the bearing plates for the brushroll as the bristles wear. The uncredited spokesmodel is very Vanna White-like in her determined smiling ability to keep taking the vacuum apart over and over as she points out the item in question with one double-tapping index fingernail.
Speaking of clumping Kitty Litter, just guess what half the bag load was?
