I own a Keeler Bagless Conversion...
First of all, I have some knowledge of vacuums. I was a Rainbow distributor, a Lux branch manager the last 4 years they were still the old American Electrolux corp. To my knowledge I am the only one ever invited to address the engineering team at Electrolux, which I did in 2000 at the behest of James McCain, chief of operations. I sold Kirbys several times, H I, G4, Ultimate and Diamond, won a few trips, etc.
I have met Jim and his wife Judy (and all 5 canine children) I was going to buy their vac shop in Mt Juliet, TN, but was unable to sell my home in time to do so. They are hospitable, wonderful people.
I have used the bagless conversion on my G4 for seven months, and it does indeed work extremely well. It is easy to tell when the unit has lost sufficient cleaning power to necessitate emptying/cleaning:
the Kirby bagless picks the carpet up with the characteristic 'buzz' usually one notch higher than with the bag. When it can not hold on to the carpet with normal movement at the height adjustment one would normally use with the bag, then it is time to dump the container and clean the filter.
I supplement my income by cleaning for several affluent clients, all of whom are multiple pet owners. I would have a large expenditure on Kirby bags without the bagless conversion. Two of my clients have remarked they like seeing me enter with the clean dirt canister because they can see that I am not dragging someone else's dirt into their home. (My clients are anally retentive, and I charge accordingly. The Kirby is shined before each cleaning job)
Where the bagless conversion really shines is pet hair and sand. Carpet fresh? Not so much. The filter does clog very quickly with fine powder. When I vacuum upholstery and mattresses I am more likely to use the bag. Carpet, bare floors and stairs with the hand portable, the bagless unit for sure.
As for the numbers and statistics: "It is aerodynamically impossible for a bumblebee to fly, given its body mass and proportionally too small wings. The bumblebee doesn't know this and happily flies anyway." The Keeler Kirby bagless conversion works, I know it does and my clients do too.
As any engineer worth his (or her) salt can tell you, some things which are possible/impossible on paper turn out the complete opposite of what "must" be true. The Keeler Kirby bagless conversion works.
Galileo was put to death for stating what we now know to be obvious: the earth is not the center of the universe, and it revolves around the sun. All great truths begin as heresies. The Keeler Kirby bagless conversion works.
And while the bagless unit offends the aesthetic sensibilities of some, it certainly is not on a par with attaching arms to the Venus De Milo. If you think that it is you need to stop sleeping with your Kirby and get a life! It is just an adaptaion of an existing product for particular uses. No one is saying it can, or should totally replace the bag. I also have a cloth bag on a mini emptor, which I use when I have carpet fresh to dig out. It clogs the paper bags too quickly. So, paper bags, cloth bag, bagless canister. I use whatever the situation calls for. But, for the record, the Keeler bgaless conversion does work. It does clog, true, but it still has enough useful cleaning time before it clogs to make it a very useful, practical, thrify option.
"You shall know the truth, and the truth shall set you free, but that doesn't mean it's not going to piss you off first"
There are still people who belive the earth is flat, too. You can say what you want, but I and at least 115 other Kirby owners know the truth: the Keeler Kirby bagless conversion works.
Peace,
