I further agree.
I primarily use Electrolux Turbo in my Kirbys mainly cause it's what I have on hand. Not any more expensive then Kirby but I am used to it. My dogs like it. I've used Kirby as well as other commercial dry foams with good results. For rentals, I use Franklin Dry Foam which is more concentrated so it can go further or produce good suds.
I actually use my vintage Kirby Dual Sanitronic 50 w/ its original Rug Renovator w/ satisfying results compared to the big "G" series. Not better, just good for its age. I empty 1 little tank per room but it works. Just a note, this would be the 1st running model of 1965 where we are introduced to the, then called, "Rug Renovator" known now as the Carpet Shampoo System. Notice the same basic design exist today. I don't mind using this in small room s since the stay is shorter so you can get closer and more snug fit up against ways where tray can't get.
Be sure to store your shampooer tray in its box properly in the fitted cradle so not let sit on its soft rubber guides. This, if deformed, will cause uneven foam spreading. The older kits didn't sit in bottom but take care to set down so not to let other items lean against the rubber. Keep facing to side of box.
Easy to clean up as said many times. Not the quickest, but easy. To help dry out the brush I lift roller and let spin for a moment, usually 30 seconds, before taking apart to help make clean up a little easier. If brush is dry, you can simply comb out dry foam & dirt by hand so you are not waiting a long time to put away. Avoid putting away with a wet brush.
