I let my mom borrow a G5 that I was going to sell for $150. She wanted to vacuum her house really good before it got steam cleaned, so I told her she could borrow it and give it a good test drive (it was dead when I got it, I opened it up and cleaned the contacts and changed the cord end and it magically started working, but I wanted to make sure it would keep working before I sold it.) Anyways she liked how well it cleaned she wanted to keep it. lol
The G series are great cleaners but I prefer the size and design of the "Classic" Kirbys, I have a Tradition and Heritage84 setup with cloth HEPA bags, I need to get some ball bearing rollers for them for the best performance. I'm lazy so I have the Tradition with the nozzle attached for doing the carpet, and the H84 with the hose connected so I just grab which one I need. LOL
